"One-stop shopping into a world of climate information"

In the wake of a recent series of so-called "Climategate" scandals, the Obama Administration is creating a new federal agency focused gathering and disseminating information on climate change. On the surface this appears to be a good thing. But let's hope that this is not merely a defensive measure that provides excuses for delaying the implementation of measures -- such as the immediate deployment of U.S. offshore wind farms -- designed to mitigate the effects of humanity's inadvertent experiment with the atmosphere.

New Federal Climate Change Agency Forming

Obama administration to set up new agency to study, monitor climate change

WASHINGTON

The Obama administration is forming a new agency to study and report on the changing climate.

Also known as global warming, climate change has drawn widespread concern in recent years as temperatures around the world rise, threatening to harm crops, spread disease, increase sea levels, change storm and drought patterns and cause polar melting.

Commerce Secretary Gary Locke and Jane Lubchenco, head of the National Oceanic and Atmospheric Administration, planned to announce Monday that NOAA will set up the new Climate Service to operate in tandem with NOAA's National Weather Service and National Ocean Service.

NOAA recently reported that the decade of 2000-2009 was the warmest on record worldwide; the previous warmest decade was the 1990s. Most atmospheric scientists believe that warming is largely due to human actions, adding gases to the atmosphere by burning fossil fuels such as coal and natural gas.

Researchers and leaders from around the world met last month in Denmark to discuss ways to reduce climate-warming emissions, and a follow-up session is planned for later this year in Mexico.

"More and more people are asking for more and more information about climate and how it's going to affect them," Lubchenco explained. So officials decided to combine climate operations into a single unit.

Portions of the Weather Service that have been studying climate, as well as offices from some other NOAA agencies, will be transferred to the new NOAA Climate Service.

The new agency will initially be led by Thomas Karl, director of the current National Climatic Data Center. The Climate Service will be headquartered in Washington and will have six regional directors across the country.

Lubchenco also announced a new NOAA climate portal on the Internet to collect a vast array of climatic data from NOAA and other sources. It will be "one-stop shopping into a world of climate information," she said.

Creation of the Climate Service requires a series of steps, but if all goes well, it should be finished by the end of the year, officials said.

In recent years, a widespread private weather forecasting industry has grown up around the National Weather Service, and Lubchenco said she anticipates growth of private climate-related business around the new agency.

While most people notice the weather from day to day or week to week, climate looks at both the averages and extremes of weather over longer periods of time. And understanding both weather and climate, and their changes, are vital to much of the world's economic activity ranging from farming to travel to energy use and production and even food shipments and disease prevention.

Atmospheric scientists have long joked that climate is what you expect and weather is what you get. But greenhouse warming is changing what can be expected from climate, and researchers are seeking to understand and anticipate the impacts of that change.

"I'm not holding my breath for a consensus"

The Cape Wind saga continues along a long and winding road riddled with potholes and detours. Interior Secretary Salazar (sporting the cowboy hat) visited Cape Cod last week and promises a decision on the nation's first proposed offshore wind farm by April. (GW)

Mass. wind farm that Obama administration might support meets strong resistance

ABOARD THE IDA LEWIS -- Interior Secretary Ken Salazar journeyed out into Nantucket Sound on a Coast Guard vessel last week to signal the Obama administration's readiness to put some muscle behind wind energy. To do that, Salazar has to resolve a battle over building a wind farm on 25 square miles of open water that has driven a rift between environmentalists, infuriated local Native Americans and threatened one of the administration's cherished priorities.

The nearly decade-long fight over whether to construct a 130-turbine offshore wind farm near Martha's Vineyard has spurred numerous state and federal regulatory reviews. It has cost millions in lobbying fees and has prompted an intense political debate on Cape Cod and in Washington, setting those who back renewable energy against those who want to preserve the natural beauty of Nantucket Sound.

"The worst thing we can do for the country is to be in a state of indecision, and this application has been in a state of indecision for a very long time," said Salazar, who came to see the proposed site of the Cape Wind project and to meet with tribes that oppose it.

With many other obstacles resolved, including the wind farm's potential hindrance to navigation and fishing and harm to birds, the tribes represent the project's latest challenge: They practice a sunrise ritual every morning on the sound and say they may have artifacts buried beneath the seabed. They have managed to qualify the sound for listing on the National Register of Historic Places, which could restrict its commercial use.

Salazar got up before dawn Tuesday to observe a site where the Mashpee Wampanoag's sunrise ceremony takes place before meeting with representatives of the Aquinnah and the Mashpee tribes.

He said that although his department is trying to broker a deal between the tribes and Energy Management, the company seeking to build the farm, "I'm not holding my breath for a consensus." And if the two sides cannot resolve their differences, he said, he will do it himself by April.

The venture stands as a critical test of whether the Obama administration, which views investing in renewable energy as key to reviving the economy and combating climate change, can launch the clean-energy revolution it has promised voters.

Ian Bowles, the Massachusetts energy and environmental affairs secretary, called the Cape Wind project "symbolic of America's struggle with clean energy. Its symbolism has risen above the number of megawatts."

Both sides agree that this offshore wind project, which would be the first in the United States and would furnish about 75 percent of Cape Cod's energy, shows just how hard it will be to construct wind farms off America's coasts.

"The tortured history of Cape Wind is not just a not-in-my-backyard story of fisherman and wealthy people on the Cape," said Michael Moynihan, director of the Green Project at NDN, a centrist think tank. "It is emblematic of the difficulty of getting wind online, anywhere in America, with a system designed a century ago that is frankly hostile to renewable energy."

Wind energy still remains a tiny player, providing less than 2 percent of the nation's supply. Although the United States leads the world in total wind capacity to its power grid, it ranks fifth on a per-capita basis. Last year, China outpaced it for the first time in terms of new installations and manufacturing of wind turbines.

In the short term, land-based wind projects represent a better investment because they can win federal approval faster than the roughly dozen offshore ventures pending, according to Sanjay Shrestha, a senior analyst for Lazard Capital Markets. "If you can do it onshore and do it quicker, why wouldn't you do it?" he asked.

Under Salazar, the Interior Department has launched a concerted effort to streamline approval for offshore projects. In April, the Minerals Management Service finalized rules for placing offshore wind farms, allowing states to decide where and under what terms they will accept bids for wind projects. Salazar has invited the governors of every East Coast state to meet with him Feb. 19 to devise a regional strategy for wind development off the Atlantic Coast.

But these moves have not resolved some of the structural problems facing renewable energy, including utilities have little incentive to gamble on cutting-edge technology that will raise the costs to consumers in the short term. Even under the new permit system, any project must be vetted for compliance with the Endangered Species Act, the National Historic Preservation Act and several other federal laws.

"It's not going to happen overnight," said MMS Director Liz Birnbaum.

No other renewable-energy project in America has followed as convoluted a path as Cape Wind. Unveiled in 2001, the roughly 25-square-mile proposal has soured longstanding friendships and opened political fault lines within the Democratic Party. The late Sen. Edward M. Kennedy (D-Mass.), whose family compound overlooks the sound, fiercely opposed it, while Gov. Deval L. Patrick has pushed for it as part of an ambitious plan to generate 20 percent of the state's electricity with renewable energy by 2025.

And all of the recent talk about the importance of clean energy has done little to shift entrenched attitudes on the project.

"I have not seen a lot of softening on either side of this," said Cape Air Chief Executive Dan Wolf, a local airline executive who initially opposed the wind farm but now backs it "as a transition from the way we produce energy now to the way we will produce energy in 100 years."

If anything, the recent recession has given opponents a new line of argument against the project. Wayne Kurker, the owner of Hyannis Marina, said his neighbors realize they might end up paying more if they switch from traditionally generated electricity to wind power.

"That's what everyone's been talking about in the last 12 months -- how it's going to drive up electricity rates," he said.

"What happens to Cape Wind, whether it goes up or goes down, will not be determinative of wind energy in the United States," Salazar told reporters after traveling to the stretch of water where the wind farm would be built. "The president and the department have made renewable energy one of the imperatives in our country."

"It's representative in that there are tradeoffs and conflicts," said Interior Deputy Secretary David Hayes, who is overseeing the Cape Wind decision. "That's true of oil and gas, and it's true for renewable energy."

How sustainable are the links in your supply chain?

There is always a lot more than what meets the eye in determining whether a particular product or practice is truly sustainable. Most products depend upon a varied and often dispersed network of suppliers to provide critical inputs. If any of the links in the supply chain employ unsustainable practices can the final product be deemed sustainable? (GW)

Sustainable development of tea industry in China

Tea originated in China, and today the country is the world’s biggest producer and has the most tea farmers (around 80 million). Despite this, few consumers (either in the Chinese domestic market or internationally) have clear picture about the tea supply chain (which involves processing, matching, packing, transporting, and selling), and thus have no idea how tea consumption affects the livelihood of tea farmers. This is in stark contrast with the coffee industry, where the supply chain has been the subject of keen interest for many years.

Generally speaking an ordinary tea farming household in China occupies around 2-3 hectares, but generates an income of only around 50 per cent of an average farming household. The livelihood of tea farmers is thus one of the critical issues concerning sustainability of the tea industry in China.

Another issue is supply chain management. The sustainable development of supply chains in China has been a hot topic for around 15 years. However, the focus has been on manufacturing, especially in labour intensive sectors. This is starting to change, with attention broadening to other sustainability issues such as food safety and traceability of products, and with it the social responsibility of companies in the primary sector. In the past few years, international buyers and sourcing agents have been starting to conduct social and environmental audits during the production process in tea processing companies. Unfortunately, the general view is that the labour conditions and environmental issues raised during these audits are of insignificant concern for Chinese management.

It is in this context, then, that the “First Seminar on Sustainable Tea in China” was and held on 23 January. The event was hosted and organised by the China Tea Marketing Association, Solidaridad China (an initiator and driving force behind Fair Trade, and an active player in organic agriculture), and UTZ Certified (one of the largest coffee certification programs in the world). The major aims were to explore opportunities to promote the sustainable development of the tea industry in China, which the organizers believe can result in a fair and balanced development model addressing both social and ecological concerns.

More than 60 representatives locally and internationally joined the seminar, including representatives from local government departments such as the Ministry of Commerce and the Ministry of Agriculture. Of particular interest was the inclusion of local producers; for instance, the Wu Yu Tai Tea Company (a well known Chinese brand) was invited to present about its experience in managing the supply chain. There was also an interesting research report by a professor from the Yunnan Agricultural University on the livelihood of farmers’ in southwest China.

Speakers from the international community working on sustainable tea also shared their experiences and knowledge. Solidaridad, which has supported sustainable products over a long period of time, explained how it had developed a global sustainable tea program. Organisations overseeing international standards and certifications on sustainable products (such as UTZ and the Ethical Tea Partnership) explained how their standards and certifications work and provided helpful information to companies that attended.

One of the outcomes of the seminar was that the China Tea Marketing Association will set up a specialised working group with members from the local and international tea community to examine and design a working plan and measures to promote the sustainable development of the tea industry in China.

One of the participants at the seminar was from an NGO called Inno Community Development Organisation, which has its headquarters in Guangzhou and branches in Shanghai and Beijing. Inno is the originator and developer of the first online purchasing platform for fair-trade products in China (www.fairtradecn.org), and the organisation believes that there is great market potential for sustainable tea in China. Inno also provides companies with fair-trade products through procurement of office refreshment such as coffee and tea.

Along with Inno, CSR Asia is expecting more and more Chinese customers will be interested in such sustainable products.

Ethiopia firm recycling tyres into shoes does big business via internet

SoleRebels offers inspiration to Africans by thriving in global market

Old truck tyres never die, they just turn into sandals. For decades that has been the tradition in Ethiopia, where everyone from farmers to guerrilla fighters has fashioned worn-out road rubber into cheap, long-lasting footwear.

But now, thanks to a young woman entrepreneur who has combined the internet's selling power with nimble business practices more often associated with Asian countries, the idea has been turned into an unlikely international hit. By adding funky cotton and leather uppers to recycled tyre soles, Bethlehem Tilahun Alemu has sold many thousands of pairs of handmade flip-flops, boat shoes, loafers and Converse-style trainers to foreign customers.


In the run-up to Christmas, workers at the soleRebels "factory" – a small house on the outskirts of the Ethiopian capital – were frantically cutting, sewing and gluing to fulfil internet purchases from customers as far away as Canada and Australia. Alemu's brother packed pairs of cotton and suede trainers into a box about to be couriered to Amazon.com, the company's main customer, which receives the shoes in the US three to five days after placing its bulk order. "We are sitting in Addis Ababa but acting like an American company," said Alemu, an excitable 30-year-old former accountant who is fond of reeling off the numbers that illustrate her firm's rapid growth.


Just five years after start-up, soleRebels employs 45 full-time staff who can produce up to 500 pairs of shoes a day. More will be hired after next month once the footwear range, priced between £21 and £40, goes on sale online in the UK and Japan on Amazon's new footwear website javari.co.uk. The company's sales target for 2010 is an impressive £300,000, but Alemu's ultimate goal – one she seems deadly serious about – is far loftier: to become "the Timberland or Skechers of Africa".


The success of soleRebels, which has thrived in the global market with no outside support other than a government line of credit to help meet large orders, is challenging preconceptions both about Ethiopia and the best way to lift its people out of poverty.


Abroad, the landlocked country still suffers from an image of a hungry and often helpless nation, with 6 million people requiring food relief and billions of dollars of aid each year. But where some might see despair Alemu saw inspiration. While brainstorming for an Ethiopian-flavoured product that could be produced in a sustainable manner, she remembered the truck tyre sandals, which were used by local fighters who repelled Italian soldiers many decades ago, as well as the rebels who marched into Addis Ababa in 1991 and today run the government.


"Recycling is a way of life here – you don't throw things away that you can use again and again," she said. "I wanted to build on that idea."


At the time other Ethiopian shoe companies were struggling to compete with cheap imports from China. SoleRebels decided to concentrate instead on the export market, where Alemu reasoned that customers would pay good money for uniquely designed products. She found a supplier who could deliver old truck tyres and tubes, and hired women to spin, weave and dye pieces of locally-grown cotton, jute and hemp using skills passed down through generations.


Tracking international shoe fashion trends on the web, Alemu designed a range of footwear. Some are simple cotton-covered or leather covered flip-flops and sandals with names like Class Act and Gruuv Thong. The bestselling Urban Runner takes inspiration from the classic Converse All Star "lo-top" trainer, with a piece of inner tubing for the toecap and organic cotton-covered footbeds. Virtually all the materials are locally sourced, including the camouflage material used on some shoes, which is cut from old army uniforms.


After receiving international fair trade certification, Alemu began bombarding US stores and websites with emails and samples. Shops such as Whole Foods and Urban Outfitters agreed to stock the shoes, which were imported duty-free under the US African Growth and Opportunity Act, helping prices stay competitive. As word spread, individual customers began buying directly from the soleRebels website - the Christmas order from Canada included a scanned trace of the customer's foot - with the shoes usually arriving by courier from Ethiopia within a week. But business really took off when Amazon signed up as a customer. Alemu is an evangelist for the online business model, saying it allows the company "to understand the market needs and demands in real time".


SoleRebels negotiates directly with retailers, doing everything from ordering processing to credit collection itself, and ensures most of the final sales price remains in Ethiopia. As a result, Alemu said, she can pay her staff between £1.20 a day for trainees and £7 a day for experienced artisans – good wages by local standards. In turn, the government earns more taxes, spurring more development.


"In Ethiopia we have become used to taking money from the west, to always getting help," said Alemu. "That does not make for a sustainable economy. We need to solve our own problems."


The success has enabled soleRebels to begin construction of a solar-powered factory near the current workshop, to allow for expanded production. While it will better showcase the company's eco-friendly methods, that's not the main reason customers like the shoes, Alemu said. "People buy soleRebels because they are good, not just because they are green or from Ethiopia. Our product speaks for itself."

''It's more legal for people to grow marijuana in L.A. than flowers''

Decades ago many affluent urban residents fled the city, sidestepped the suburbs and built homes in the exurbs -- areas that bridged the suburbs and rural communities. They said they wanted to enjoy the rural life. It didn't take long before these new exurbanites began complaining about the sights, sounds and smells of nearby farms. Inevitable cultural clashes followed.

Today with the exploding interest in urban agriculture, we're seeing this conflict turned on its head.

By the way, I received several comments on another article on urban agriculture that I posted a couple of weeks ago cautioning that urban farmers need to be sure to get their soil tested to check for contaminants -- lead, among others being a major concern. A point well taken. (GW)

Urban Farmers Fight Nationwide to Sow Green Biz

LOS ANGELES (AP) -- Tara Kolla fancied herself a green thumb-turned-green businesswoman when she planted an organic flower plot in her yard and sold poppies, sweet peas and zinnias at the local farmers market. For her neighbors, it was an eyesore.

Where Kolla saw her efforts as creating a lush sanctuary, her neighbors witnessed dusty pots, steaming compost, flies and a funky aroma on their tiny cul-de-sac in Los Angeles. They complained to zoning officials -- and prevailed.

Kolla and other urban farmers are fighting back by challenging city halls across the country to rewrite ordinances that govern residential gardens. They believe feeding their fellow urbanites homegrown tomatoes, fresh eggs and sweet corn will change the world one backyard at a time.

Seattle has loosened its rules for backyard goats, New York City's health department is taking steps to legalize beekeeping and Detroit is looking into regulating compost and greenhouses.

In Detroit, where zoning laws ban growing crops and raising livestock for profit, city planner Kathryn Lynch Underwood is part of a work group rewriting the regulations and defining what kinds of urban farms might need more oversight.

''The city has not been treating it as an illegal use or a nuisance because it has been a good thing,'' Underwood said.

She is hopeful that urban agriculture and the city's nearly 1,000 community gardens will create good jobs in a city that desperately needs them and put vacant lots to use in blighted neighborhoods.

Kolla, meanwhile, found a loophole allowing her to grow vegetables while lobbying for the right to set up a city farm at her home just four miles from the urban jungle of downtown Los Angeles.

The challenge for cities is to balance the potential to grow green businesses with the concerns of neighbors who don't want a thriving, for-profit enterprise next door, never mind the noise and smells that come from compost and small livestock.

Urban agriculture crosses jurisdictional lines, said Alfonso Morales, a professor of planning at the University of Wisconsin. He advises cities to set up a one-stop-shop for urban farms, like they have for small business development, so that city farmers can deal with zoning, home business regulations and nuisance laws all in one place.

''There's such enthusiasm that people push the laws and upset their neighbors,'' he said. ''The fact is you can't do anything you want on your property.''

While most urban farms operate under the radar of city officials and many neighborhoods welcome productive plots and even backyard chickens, other city growers run into trouble with neighbors who won't be placated with gifts of salad greens or fresh eggs.

In middle class areas, concerns about property values and aesthetic differences lead to conflicts.

Kolla alienated neighbors on her quiet cul-de-sac of Spanish bungalows and neat green lawns in the city's Silver Lake section when she began peddling organic bouquets at farmers markets that she grew on her 21,000 square-foot lot.

''They're trying to grow it into something bigger than what should be in a small neighborhood,'' said Frank San Juan, who lives across the street from Kolla. ''When she started having these gardening workshops without telling anybody, there was no parking. You couldn't enjoy your weekends.''

Just a half century ago, Los Angeles was transforming itself from the most lucrative farm county in the nation into a major metropolis. A zoning ordinance written in 1946 as developers were cutting down the San Fernando Valley's citrus orchards to build suburbia allowed small farms to grow vegetables to truck to market, but banned growing fruit, nuts or flowers for sale on residential plots.

Kolla could get a conditional use permit, but she has a stubborn streak and it costs $15,000 just to apply. She and others are trying to reverse the zoning laws with a proposal called ''The Food and Flowers Freedom Act.''

Growers from across Los Angeles formed the Urban Farming Advocates to rally around Kolla, defend her right to grow and lobby the city.

''Most people would pay to have a view of her backyard,'' said founding member Erik Knutzen, who keeps chickens and grows food in his yard. ''I can understand someone not wanting 50 roosters or an autobody shop next door, but our proposal is about bringing common sense back to our lives.''

In July, City Council President Eric Garcetti introduced a motion to clarify city policies on urban farms and allow cultivation and sale of flowers, fruits, nuts or vegetables.

While the city farmers wait patiently for the proposal to work its way through the planning commission, Kolla started a weekly vegetable box subscription service so as not to miss too many of Southern California's long growing seasons.

She feels the distinction between vegetables and fruit is arbitrary and unscientific.

''Broccoli is a flower, and a tomato is a fruit. And some of my flowers are edible,'' Kolla said. ''It's more legal for people to grow marijuana in L.A. than flowers.''

Russia’s ambiguous land laws

It is truly amazing how threatening actions leading to individual and community empowerment can be to some (most) governments. (GW)

Russians Rally Around a Falling Enclave

MOSCOW — The bulldozers came at night, flanked by armor-clad riot police officers, to clear the houses of a small neighborhood here at the behest of Moscow’s mayor, forcing residents out into subzero temperatures.

The mayor, Yuri M. Luzhkov, said they were living on the land illegally. But as more and more homes — some stately, some mere shacks — have come tumbling down over the last week and a half, an uncharacteristically fierce backlash has broken out, challenging one of Russia’s most powerful politicians. Politicians, human rights activists, media organizations and even nationalist and anarchist groups have come to the defense of the neighborhood, called Rechnik. Legal or not, these critics say, the demolition operation has crossed the line.

“The methods used to resolve this problem were completely unacceptable,” Vladimir Lukin, Russia’s government-appointed human rights ombudsman, told the Interfax news agency on Thursday. He called on the prosecutor general’s office to investigate what he called “gross violations” of Russian law.

On Monday, residents and their supporters blocked the entrance to the neighborhood, preventing crews from resuming demolitions.

More than a dozen homes have now been destroyed, and Moscow officials have told Russian news agencies that the operation would continue throughout the week.

Sergei Mironov, the speaker of the upper house of Parliament, said the city had “discredited” itself.

“I am personally disturbed by the fact that the Moscow government decided simply to throw these people out on the streets despite the minus-20-degree temperatures,” he wrote on his blog, citing the Celsius equivalent of minus 4 degrees Fahrenheit.

Even government-run television channels, typically gushing in their coverage of top officials, have focused their cameras on dumbfounded and teary-eyed residents watching the bulldozers tear their homes apart.

Once a charming neighborhood of about 200 single-family homes, a rare sight in a city dominated by hulking apartment blocs, Rechnik has become a battleground in a long-running fight between the government and homeowners over Russia’s ambiguous land laws.

The Soviet government set aside the plot of land on the Moscow River as a gardening collective in the 1950s. Residents claim that Soviet-era permits, which many bought or inherited from the original holders, give them de facto title over the land that their houses stand on. The city says those permits are invalid, and never allowed for the large mansions and quaint cottages that the residents built.

Mr. Luzhkov, who in his 18 years as mayor has not been given to tolerating affronts to his authority, has stood firm. In an interview published Thursday in the newspaper Moskovsky Komsomolets, he called the residents “impostors” squatting on land that he said was zoned to be a park. “These cottages are located in a protected environmental zone,” he said. “The city has been saying for years that construction in this area was forbidden.”

To prove his resolve, he has promised next to send his bulldozers to a luxury housing development neighboring Rechnik, where several government ministers are said to live.

Critics have accused the mayor, whose wife is a billionaire real estate developer, of using ambiguous land laws to acquire prime property and resell it to private interests. Just over a year ago, several dozen similar homes were destroyed in a neighboring community that was in the same nebulous legal situation.

President Dmitri A. Medvedev, who has the authority to remove Mr. Luzhkov, has been silent on the issue, as has Prime Minister Vladimir V. Putin, who appointed the mayor to his current term. After years of threats and legal battles, police officers in black riot gear finally swept into Rechnik around 3 a.m. on Jan. 21, rounding up several dozen residents who had blockaded the entrance with their cars, said Konstantin Shtoiko, one of the residents. “We called the police and they told us that they were conducting a special operation as if we were terrorists in Dagestan,” Mr. Shtoiko, 39, said, referring to the volatile region neighboring Chechnya.

About a dozen homes have been demolished in the last week, and crews began tearing down more on Friday, officials said. Several elderly residents have reportedly been hospitalized with chest pains, as have others who were beaten with nightsticks.

Is climate change speeding forest growth?

It would be naive to assume that the Earth/Nature/Gaia will not/is not taking steps in response to climate change. Our planet's four-plus billion years of experience in preserving he conditions necessary for life to prevail has prepared it well to deal with threats (natural or human-induced) to its overall ecological integrity.

Nature's responses may be subtle and even be (or seem) benign or beneficial. I would, however, wager that if nations continue to drag their feet on implementing effective strategies to mitigate climate change, she may be forced to be much more aggressive. But make no mistake, Nature will adapt and thrive with or without us. (GW)

Forests are growing faster, climate change appears to driving accelerated growth

Shorelines
February 1, 2010

Speed is not a word typically associated with trees; they can take centuries to grow. However, a new study to be published the week of Feb. 1 in the Proceedings of the National Academy of Sciences has found evidence that forests in the Eastern United States are growing faster than they have in the past 225 years. The study offers a rare look at how an ecosystem is responding to climate change.

For more than 20 years forest ecologist Geoffrey Parker has tracked the growth of 55 stands of mixed hardwood forest plots in Maryland. The plots range in size, and some are as large as 2 acres. Parker’s research is based at the Smithsonian Environmental Research Center, 26 miles east of the nation’s capital.

Parker’s tree censuses have revealed that the forest is packing on weight at a much faster rate than expected. He and Smithsonian Tropical Research Institute postdoctoral fellow Sean McMahon discovered that, on average, the forest is growing an additional 2 tons per acre annually. That is the equivalent of a tree with a diameter of 2 feet sprouting up over a year.

Forests and their soils store the majority of the Earth’s terrestrial carbon stock. Small changes in their growth rate can have significant ramifications in weather patterns, nutrient cycles, climate change and biodiversity. Exactly how these systems will be affected remains to be studied.

Parker and McMahon’s paper focuses on the drivers of the accelerated tree growth. The chief culprit appears to be climate change, more specifically, the rising levels of atmospheric CO2, higher temperatures and longer growing seasons.

Assessing how a forest is changing is no easy task. Forest ecologists know that the trees they study will most likely outlive them. One way they compensate for this is by creating a “chronosequence”—a series of forests plots of the same type that are at different developmental stages. At SERC, Parker meticulously tracks the growth of trees in stands that range from 5 to 225 years old. This allowed Parker and McMahon to verify that there was accelerated growth in forest stands young and old. More than 90% of the stands grew two to four times faster than predicted from the baseline chronosequence.

Two trees tagged with a metal band and an orange ribbon.

Parker, his colleagues and a team of citizen scientists have tagged more than 20,000 trees at the Smithsonian Environmental Research Center. Photo: Kirsten Bauer.

By grouping the forest stands by age, McMahon and Parker were also able to determine that the faster growth is a recent phenomenon. If the forest stands had been growing this quickly their entire lives, they would be much larger than they are.

Parker estimates that among himself, his colleague Dawn Miller and a cadre of citizen scientists, they have taken a quarter of a million measurements over the years. Parker began his tree census work Sept. 8, 1987—his first day on the job. He measures all trees that are 2 centimeters or more in diameter. He also identifies the species, marks the tree’s coordinates and notes if it is dead or alive.

By knowing the species and diameter, McMahon is able to calculate the biomass of a tree. He specializes in the data-analysis side of forest ecology. “Walking in the woods helps, but so does looking at the numbers,” said McMahon. He analyzed Parker’s tree censuses but was hungry for more data.

Parker uses diameter tape or 'd-tape' to measure the trees. The tape is calibrated to convert the tree’s circumference, the measurement used to determine a tree’s biomass. Photo: Kirsten Bauer.

It was not enough to document the faster growth rate; Parker and McMahon wanted to know why it might be happening. “We made a list of reasons these forests could be growing faster and then ruled half of them out,” said Parker. The ones that remained included increased temperature, a longer growing season and increased levels of atmospheric CO2.

During the past 22 years CO2 levels at SERC have risen 12%, the mean temperature has increased by nearly three-tenths of a degree and the growing season has lengthened by 7.8 days. The trees now have more CO2 and an extra week to put on weight. Parker and McMahon suggest that a combination of these three factors has caused the forest’s accelerated biomass gain.

Ecosystem responses are one of the major uncertainties in predicting the effects of climate change. Parker thinks there is every reason to believe his study sites are representative of the Eastern deciduous forest, the regional ecosystem that surrounds many of the population centers on the East Coast. He and McMahon hope other forest ecologists will examine data from their own tree censuses to help determine how widespread the phenomenon is.

These findings are also important for policymakers trying to address climate change. Future carbon cap-and-trade rules will need to quantify the amount of carbon forests hold. If faster growth rates prove the norm, this could affect the formulas and the dollar value assigned to forests that are cut or conserved.

Parker and McMahon don’t expect SERC’s forest to continue growing at this accelerated rate forever. Some day the growth rate will level off. When that happens, they wonder how that will affect CO2 levels. If trees are sponges that absorb CO2, what will happen to CO2 levels in the atmosphere when the trees become saturated? It’s a question for further exploration. In the meantime, Parker will continue walking through the SERC woods, tape measure in hand carefully tracking the growth of the trees.

PNAS will make the study available online sometime this week at this link.

"...a breach of trust that cannot be tolerated’’

It really is crunch time with respect to the nation's energy future. Nature doesn't care that the Copenhagen climate summit was a flop. She will proceed to respond to humanity's carbon-loading of the atmosphere. In the meantime we will either make energy decisions by design or default.

A clean energy future based on renewable energy sources like wind and solar is the preferred design option. Nuclear energy proponents continue to insist that their technology is part of that future. Some go so far as to say that it is our best 'clean energy option'.

The default mode is to procrastinate and avoid making the hard decisions until such time as we are forced to settle for what's available/convenient/cheap -- like recommissioning aging nuclear plants.

A couple of weeks ago headlines were made when a twenty-foot section of a wind turbine on the island of Nantucket snapped off and fell harmlessly to the ground.
Some critics of wind energy suggested this was just another example (its intermittent nature being another) of why turbine technology cannot be relied upon.

Today's post provides some perspective on that issue. (GW)

Leaks imperil nuclear industry

Vermont Yankee among troubled

By Beth Daley
Boston Globe
January 31, 2010

VERNON, Vt. - The nuclear industry, once an environmental pariah, is recasting itself as green as it attempts to extend the life of many power plants and build new ones. But a leak of radioactive water at Vermont Yankee, along with similar incidents at more than 20 other US nuclear plants in recent years, has kindled doubts about the reliability, durability, and maintenance of the nation’s aging nuclear installations.

Vermont health officials say the leak, while deeply worrisome, is not a threat to drinking water supplies or the Connecticut River, which flows beside the 38-year-old plant, nor is it endangering public health. But the controversy is threatening to derail the nuclear plant’s bid, now at a critical juncture, for state approvals to extend its operating life by 20 years when its license expires in two years. Nuclear Regulatory Commission inspectors, Vermont Yankee’s owners, and state officials are tracing the source of the radioactivity and searching for other leaks in the labyrinth of below-surface pipes on the plants’ property about 10 miles from the Massachusetts border.

The timing couldn’t be worse for the nuclear industry, coming as it attempts a broad rebirth as a green energy source in the battle against global warming; the reactors do not emit greenhouse gases that cause the atmosphere to warm.

Memories of the accidents at Three Mile Island and Chernobyl are receding and many in the public are taking a second look at nuclear. President Obama last week endorsed a new generation of nuclear power in his State of the Union address, and for the first time in decades, more than 20 new plants have been proposed.

But the leaks have the potential to slow, if not stop, the bandwagon. Crucial voices are calling for caution. “I am appalled by the safety procedures not only at Vermont Yankee, but at other nuclear facilities across the country who have failed to inspect thousands of miles of buried pipes at their facilities,’’ US Representative Edward J. Markey of Massachusetts, the chairman of the House Energy and Environment Subcommittee, said last week. Earlier this month, Markey asked the US Government Accountability Office to investigate the integrity, safety, inspections, and maintenance of buried pipes at nuclear plants.

Critics say the problems with buried pipes are evidence the plants are too old and poorly maintained to continue to safely operate as many - including plants in Seabrook, N.H., and Plymouth - seek extensions of their original 40-year operating licenses. Nuclear advocates, and the Nuclear Regulatory Commission, say that while the leaks of a radioactive form of water containing tritium are serious, those that have contaminated groundwater have not exceeded regulatory limits or harmed the structural integrity, operation, or safety of the plants.

“No leak of tritium has ever had a negative impact on the health and safety of the public,’’ said Tom Kauffman, a spokesman for the Nuclear Energy Institute, a prominent industry group. In 2006, the industry took it upon itself to search more aggressively for problems with buried piping and tritium leaks.

“These are the most highly regulated, highly monitored industrialized [power plants] in the nation,’’ Kauffman said. He said the nation’s 104 nuclear plants are some of the greenest sources of energy in the country. “It is very important to keep these plants working.’’

Indeed, Vermont Yankee provides roughly one-third of the Green Mountain State’s electricity and, to the delight of many business owners and residents, it is inexpensive. That low cost - and the 650 jobs the plant provides - has won it longstanding political support in the state. Still, antinuclear sentiment, always an undercurrent in this liberal state because of the dangers of radioactive releases and waste, accelerated after the plant received NRC permission to increase its power output by 20 percent in 2006.

The next year, a cooling tower partially collapsed, and in 2008, another tower sprung a leak. The plant’s safety was not compromised, but the events stoked public concerns about the adequacy of plant maintenance. More than 200 people, evoking the 1970s grass-roots efforts against the construction of nuclear plants in New England, took part in some portions of a 127-mile march from Brattleboro to the state capital, Montpelier, earlier this month.

Then earlier this month, Vermont Yankee’s owner, Louisiana-based Entergy Corp., told state and federal regulators it had discovered elevated levels of tritium, a radioactive isotope of hydrogen, in a 30-foot-deep monitoring well on the property as part of the voluntary industry effort to look for leaks. Two weeks later, Entergy said it found much higher levels of tritium - along with Cobalt-60, another radioactive isotope - in a 40-foot-long trench that houses pipes. It is unclear whether the two areas of contamination are related.

Tritium, while found in nature in small amounts, is produced as a byproduct in nuclear power plants. The US Environmental Protection Agency says tritiated water increases the risk of cancer if someone drinks it, but the radiation is low-level and leaves the body quickly. The agency has set a drinking water standard for tritium of 20,000 picocuries - a measure of radioactivity - per liter.

The test well, which is not used for drinking water, has registered increasingly higher levels of tritium in recent weeks - topping out at 29,000 picocuries per liter. The trench had levels in the millions of picocuries per liter. Vermont Yankee is drilling seven more wells to see how widespread the problem is.

“Obviously we are taking this very seriously,’’ said plant spokesman Rob Williams, as he guided a reporter through a maze of security fencing to view one of the monitoring wells near the Connecticut River. He stressed that the company was doing everything it could to figure out the extent of the problem and its source. The plant told regulators about the elevated levels as soon as they were found, even though they were below levels required to be reported, he said.

Across the country, tritium leaks have not prevented re-licensing of the nation’s nuclear plants by the NRC, which has extended the operating life of 59 reactors and is considering or expected to consider 37 other applications in the next seven years.

In December, the agency issued a report noting that an evaluation of buried piping showed that corrosion, where leaks can spring from, tends to occur in small areas where anti-corrosion coating is damaged. The agency concluded that its oversight of the issue is adequate, but spokesman Neil Sheehan said in an e-mail that the NRC is “a learning agency’’ and would continue to review any new information and change policies as needed to ensure safety.

The leaks at Vermont Yankee have caused a credibility problem for the plant’s owner. State officials have charged that Entergy officials misled them on a number of occasions by denying the plant had buried piping that could carry radioactive material. Last week, Governor Jim Douglas, a longtime supporter of the plant, asked legislators to delay a vote needed for the plant’s re-licensing. He also called for a state board to stop considering Entergy’s request to spin off Vermont Yankee into a subsidiary with its other nuclear plants, a move that the Vermont Public Interest Research Group, a consumer and environmental non-profit, says could limit the parent company’s financial liability when the plant shuts down.

“What has happened at Vermont Yankee is a breach of trust that cannot be tolerated,’’ Douglas said in a statement last week. Until questions are answered, he said, “decisions about the long-term future of the plant should not be made.’’

Entergy, in a statement, said that it was disappointed by Douglas’s decision but is conducting an investigation “to get to the bottom of how and why the company provided conflicting information to state officials.’’

The Brattleboro-based New England Coalition, longtime critics of nuclear energy, said the buried-pipe problem at Vermont Yankee underscores a far larger one for the nation - its nuclear plants are old.

“It is the canary in the coal mine,’’ said coalition codirector Clay Turnbull.

China's great leap forward on renewable energy

America's vast offshore wind resource positions the U.S. to be a leader in offshore wind energy production and a premier developer and manufacturer of offshore wind energy technology. But an unfortunate (hardly funny) thing happened on our way to offshore wind primacy.

As Cape Wind -- the nation's first proposed offshore wind farm -- struggles through it's ninth year of permitting, China has leapfrogged ahead of us and has become the world leader in the manufacture of wind turbines.


While China is still far down on the list of installed offshore wind capacity, they're still ahead of the U.S. Even though more than 800 megawatts separates them from the leader (UK), I would't bet against China closing that gap pretty fast. (GW)


China Leading Global Race to Make Clean Energy

TIANJIN, China — China vaulted past competitors in Denmark, Germany, Spain and the United States last year to become the world’s largest maker of wind turbines, and is poised to expand even further this year.

China has also leapfrogged the West in the last two years to emerge as the world’s largest manufacturer of solar panels. And the country is pushing equally hard to build nuclear reactors and the most efficient types of coal power plants.

These efforts to dominate renewable energy technologies raise the prospect that the West may someday trade its dependence on oil from the Mideast for a reliance on solar panels, wind turbines and other gear manufactured in China.

“Most of the energy equipment will carry a brass plate, ‘Made in China,’ ” said K. K. Chan, the chief executive of Nature Elements Capital, a private equity fund in Beijing that focuses on renewable energy.

President Obama, in his State of the Union speech last week, sounded an alarm that the United States was falling behind other countries, especially China, on energy. “I do not accept a future where the jobs and industries of tomorrow take root beyond our borders — and I know you don’t either,” he told Congress.

The United States and other countries are offering incentives to develop their own renewable energy industries, and Mr. Obama called for redoubling American efforts. Yet many Western and Chinese executives expect China to prevail in the energy-technology race.

Multinational corporations are responding to the rapid growth of China’s market by building big, state-of-the-art factories in China. Vestas of Denmark has just erected the world’s biggest wind turbine manufacturing complex here in northeastern China, and transferred the technology to build the latest electronic controls and generators.

“You have to move fast with the market,” said Jens Tommerup, the president of Vestas China. “Nobody has ever seen such fast development in a wind market.”

Renewable energy industries here are adding jobs rapidly, reaching 1.12 million in 2008 and climbing by 100,000 a year, according to the government-backed Chinese Renewable Energy Industries Association.

Yet renewable energy may be doing more for China’s economy than for the environment. Total power generation in China is on track to pass the United States in 2012 — and most of the added capacity will still be from coal.

China intends for wind, solar and biomass energy to represent 8 percent of its electricity generation capacity by 2020. That compares with less than 4 percent now in China and the United States. Coal will still represent two-thirds of China’s capacity in 2020, and nuclear and hydropower most of the rest.

As China seeks to dominate energy-equipment exports, it has the advantage of being the world’s largest market for power equipment. The government spends heavily to upgrade the electricity grid, committing $45 billion in 2009 alone. State-owned banks provide generous financing.

China’s top leaders are intensely focused on energy policy: on Wednesday, the government announced the creation of a National Energy Commission composed of cabinet ministers as a “superministry” led by Prime Minister Wen Jiabao himself.

Regulators have set mandates for power generation companies to use more renewable energy. Generous subsidies for consumers to install their own solar panels or solar water heaters have produced flurries of activity on rooftops across China.

China’s biggest advantage may be its domestic demand for electricity, rising 15 percent a year. To meet demand in the coming decade, according to statistics from the International Energy Agency, China will need to add nearly nine times as much electricity generation capacity as the United States will.

So while Americans are used to thinking of themselves as having the world’s largest market in many industries, China’s market for power equipment dwarfs that of the United States, even though the American market is more mature. That means Chinese producers enjoy enormous efficiencies from large-scale production.

In the United States, power companies frequently face a choice between buying renewable energy equipment or continuing to operate fossil-fuel-fired power plants that have already been built and paid for. In China, power companies have to buy lots of new equipment anyway, and alternative energy, particularly wind and nuclear, is increasingly priced competitively.

Interest rates as low as 2 percent for bank loans — the result of a savings rate of 40 percent and a government policy of steering loans to renewable energy — have also made a big difference.

As in many other industries, China’s low labor costs are an advantage in energy. Although Chinese wages have risen sharply in the last five years, Vestas still pays assembly line workers here only $4,100 a year.

China’s commitment to renewable energy is expensive. Although costs are falling steeply through mass production, wind energy is still 20 to 40 percent more expensive than coal-fired power. Solar power is still at least twice as expensive as coal.

The Chinese government charges a renewable energy fee to all electricity users. The fee increases residential electricity bills by 0.25 percent to 0.4 percent. For industrial users of electricity, the fee doubled in November to roughly 0.8 percent of the electricity bill.

The fee revenue goes to companies that operate the electricity grid, to make up the cost difference between renewable energy and coal-fired power.

Renewable energy fees are not yet high enough to affect China’s competitiveness even in energy-intensive industries, said the chairman of a Chinese industrial company, who asked not to be identified because of the political sensitivity of electricity rates in China.

Grid operators are unhappy. They are reimbursed for the extra cost of buying renewable energy instead of coal-fired power, but not for the formidable cost of building power lines to wind turbines and other renewable energy producers, many of them in remote, windswept areas. Transmission losses are high for sending power over long distances to cities, and nearly a third of China’s wind turbines are not yet connected to the national grid.

Most of these turbines were built only in the last year, however, and grid construction has not caught up. Under legislation passed by the Chinese legislature on Dec. 26, a grid operator that does not connect a renewable energy operation to the grid must pay that operation twice the value of the electricity that cannot be distributed.

With prices tumbling, China’s wind and solar industries are increasingly looking to sell equipment abroad — and facing complaints by Western companies that they have unfair advantages. When a Chinese company reached a deal in November to supply turbines for a big wind farm in Texas, there were calls in Congress to halt federal spending on imported equipment.

“Every country, including the United States and in Europe, wants a low cost of renewable energy,” said Ma Lingjuan, deputy managing director of China’s renewable energy association. “Now China has reached that level, but it gets criticized by the rest of the world.”

Unapologetic insubordinate

Howard Zinn was, and will forever be one of the noblest and most courageous defenders of Truth the world has known. (GW)

Saying goodbye to my friend Howard Zinn

By Alice Walker
Boston Globe
January 31, 2010

On hearing the news of his death.

Me: Howie, where did you go?

Howie: What do you mean, where did I go? As soon as I died, I went back to Boston.

I met Howard Zinn in 1961, my first year at Spelman College in Atlanta. He was the tall, rangy, good-looking professor that many of the girls at Spelman swooned over. My African roommate and I got a good look at him every day when he came for his mail in the post office just beneath our dormitory window. He was always in motion, but would stop frequently to talk to the many students and administrators and total strangers that seemed attracted to his energy of non-hesitation to engage. We met formally when some members of my class were being honored and I was among them. I don’t remember what we were being honored for, but Howard and I ended up sitting next to each other. He remembered this later; I did not. He was the first white person I’d sat next to; we talked. He claimed I was “ironic.’’ I was surprised he did not feel white.

I knew nothing of immigrants (which his parents were) or of Jews. Nothing of his father’s and his own working class background. Nothing of his awareness of poverty and slums. Nothing of why a white person could exist in America and not feel white: i.e., heavy, oppressive, threatening, and almost inevitably insensitive to the feelings of a person of color. The whole of Georgia was segregated at that time; and in coming to Spelman I had had a run-in with the Greyhound bus driver (white as described above) who had forced me to sit in the back of the bus. This moment had changed my life, though how that would play out was of course uncertain to a 17-year-old.

One way it did play out was that the very next summer I was on my way to the Soviet Union to see how white those folks were and to tell as many of them as I could, even if they were white, that I did not agree to my country’s notions of bombing them. I didn’t see a lot of generals, but children and women and men and old people of both sexes were everywhere. They were usually smiling and offering flowers or vodka. There was no “iron curtain’’ between us, as I’d been told to expect by Georgia media. I love to tell the story of how I was so ignorant at the time I didn’t have a clue who folks were queuing up to see in Lenin’s tomb; nor did I even know what the Kremlin was. I also didn’t speak a word of Russian.

Coming back to Spelman, I discovered Howard Zinn was teaching a course on Russian History and Literature and a little of the language. I signed up for it, though I was only a sophomore and the course was for juniors (as I recall). I had loved Russian Literature since I discovered Tolstoy and Dostoevsky back in the school library in Putnam County, Georgia. As for the Russian language, as with any language, I most wanted to learn to say hello, goodbye, please, and thank you.

Howard Zinn was magical as a teacher. Witty, irreverent, and wise, he loved what he was teaching and clearly wanted his students to love it also. We did. My mother, who earned $17 a week working 12-hour days as a maid, had somehow managed to buy a typewriter for me and I had learned typing in school. I said hardly a word in class (as Howie would later recall), but inspired by his warm and brilliant ability to communicate ideas and conundrums and passions of the characters and complexities of Russian life in the 19th century, I flew back to my room after class and wrote my response to what I was learning about these writers and their stories that I adored. He was proud of my paper, and, in his enthusiastic fashion, waved it about. I learned later there were those among other professors at the school who thought that I could not possibly have written it. His rejoinder: “Why, there’s nobody else in Atlanta who could have written it!’’

It would be hard not to love anyone who stood in one’s corner like this.

Under the direction of SNCC (Student Nonviolent Coordinating Committee) many students at Spelman joined the effort to desegregate Atlanta. Naturally, I joined this movement. Howie, taller than most of us, was constantly in our midst, and usually somewhere in front. Because I was at Spelman on scholarship, a scholarship that would be revoked if I were jailed, my participation caused me a good bit of anxiety. Still, knowing that Howard and others of our professors, the amazingly courageous and generous Staughton Lynd, for instance, my other history teacher, supported the students in our struggle, made it possible to carry on. But then, while he and his family were away from campus for the summer, Howard Zinn was fired. He was fired for “insubordination.’’

Yes, he would later say, with a classic Howie shrug, I was guilty.

For me, and for many poorer students in my position, students on scholarship who also worked in the Movement to free us from centuries of white supremacy and second-class citizenship, it was a disaster. I wrote a letter to the administration that was published in the school paper pointing out the error of their decision. I wrote it through tears of anger and frustration. It was these tears, which appeared unannounced whenever I thought of this injustice to Howard and his family - whom I had met and also loved - that were observed by Staughton Lynd, who realized instantly that a) there was every chance I was headed toward a breakdown; and b) the administration would quickly find a reason to expel me from school. Added to the stress, which nobody knew about, was the fact that I was working for a well-respected older man who, knowing I had to work in order to pay for everything I needed as a young woman in school, was regularly molesting me. Lucky for me he was very old, and his imagination was stronger than his grasp. As a farm girl and no stranger to manual labor, I could type his papers with one hand while holding him off with the other. What rankled so much, then as now, is how much others respected, even venerated him.

Perhaps this was one of many births of my feminism. A feminism/womanism that never seemed odd to Howard Zinn, who encouraged his Spelman students, all of them women, to name and challenge oppression of any sort. This encouragement would come in handy, when, years later, writing my second novel, “Meridian,’’ I could explore the misuse of gender-based power from the perspective of having experienced it.

With Staughton Lynd’s help, and after he had consulted with Howie (I did not know this), I was accepted to finish my college education at Sarah Lawrence College, a place of which I had never heard. I went off in the middle of winter, without a warm coat or shoes and ice and snow greeted me. But also Staughton’s mother, Helen Lynd, who immediately provided money for the coat and shoes I needed, as well as a blanket that had been her son’s.

In my solitary room, and knowing no one on campus, I hunkered down to write. Letters to the Zinns, first of all. To inform them I had been liberated from Spelman, as they had been, and had landed.

I was Howard’s student for only a semester, but in fact, I have learned from him all my life. His way with resistance: steady, persistent, impersonal, often with humor, is a teaching I cherish. Whenever I’ve been arrested, I’ve thought of him. I see policemen as victims of the very system they’re hired to defend, as I know he did. I see soldiers in the same way. In some ways, Howie was an extension of my father, whom he never met. My father was also an activist as a young man and was one of the first black men unconnected to white ancestry or power to vote in our backwoods county; he had to pass by three white men holding shotguns in order to do this. By the time I went off to college, the last of eight children, he was exhausted and broken. But these men were connected in ways clearer to me now as I’ve become older than my father was when he died. They each saw injustice as something to be acknowledged, confronted, and changed if at all possible. And they looked for signs of humanity in their opponents and spoke to that. They both possessed a sense of humor and love of a good story that made them charismatic teachers. I recently discovered, and it amuses me, that their birth dates are close, though my father was 13 years older.

Howie and I planned to rendezvous in Berkeley in March, when he came out to spend a few weeks with his grandchildren. In April we planned to be on a panel with Gloria Steinem and Bernice Reagon at an event in New Orleans for Amnesty International. I had decided not to go, but Howie said if I didn’t come he would “sorely miss’’ me. I wrote back that in that case I would certainly be there as “soreness of any sort’’ was not to be tolerated.

Over the years I’ve been in the habit of sending freshly written poems to Roz and Howie. After her death, I continued to send the occasional poem to Howie. Last week, after the Supreme Court’s decision to let corporations offer unlimited financing to electoral candidates, I wrote a poem about what I would do if I were president, called: “If I Was President: ‘Were’ For Those Who Prefer It.’ ’’ My first act as president, given that corporations may well buy all elections in America from now on, would be to free Mumia Abu-Jamal and Leonard Peltier, both men accused of murders I’ve felt they did not commit; both men in prison for sadistically long periods of time.

Howie’s response, and the last word he communicated to me, was “Wonderful.’’ I imagined him hurriedly typing it, then flying, even at 87, out the door.

The question remains: Where do our friends and loved ones go when they die?

They can’t all go back to Boston, or wherever they’ve lived their most intense life.

I fell asleep, after leaking tears for Howie most of the day: my sweetheart’s shirt was luckily absorbent and available to me, and after tossing and turning almost all night, I had the following dream: We (Someone and I) were looking for the place we go to when we die. After quite a long walk, we encountered it. What we saw was this astonishingly gigantic collection of people and creatures: birds and foxes, butterflies and dogs, cats and beings I’ve never seen awake, and they were moving toward us in total joy at our coming. We were happy too. But there was nothing to support any of us, no land, no water, nothing. We ourselves were all of it: our own earth. And I woke up knowing that this is where we go when we die. We go back to where we came from: inside all of us.

Goodbye, Howie. Beloved. Hello.
