The Crisis Comes Ashore

by Al Gore from The New Republic. Click here to read the full article.

One important difference between the oil spill and the CO2 spill is that petroleum is visible on the surface of the sea and carries a distinctive odor now filling the nostrils of people on shore. Carbon dioxide, on the other hand, is invisible, odorless, tasteless, and has no price tag. It is all too easily put “out of sight and out of mind.” Because the impacts of global warming are distributed globally, they often masquerade as an abstraction. And because the length of time between causes and consequences is longer than we are used to dealing with, we are vulnerable to the illusion that we have the luxury of time before we begin to respond.

But neither assumption is correct. Most of the heat trapped by greenhouse gases is stored in the oceans and reemerges over time into the atmosphere. As a result, we are capable-–through inaction—of making truly disastrous consequences inevitable long before the worst impacts are manifested. Our perception of the dangers of the climate crisis therefore relies on our ability to understand and trust the conclusions reached by the most elaborate and impressive scientific assessment in the history of our civilization.

In other words, rather than relying on visceral responses, we have to draw upon our capacity for reasoning, communicating clearly with one another, forming a global consensus on the basis of science, and making a choice in favor of preventive action on a global scale.

Europe Finds Clean Energy In Trash, But U.S Lags

Click here to read the full article from the New York Times

Far cleaner than conventional incinerators, this new type of plant converts local trash into heat and electricity. Dozens of filters catch pollutants, from mercury to dioxin, that would have emerged from its smokestack only a decade ago.

In that time, such plants have become both the mainstay of garbage disposal and a crucial fuel source across Denmark, from wealthy exurbs like Horsholm to Copenhagen’s downtown area. Their use has not only reduced the country’s energy costs and reliance on oil and gas, but also benefited the environment, diminishing the use of landfills and cutting carbon dioxide emissions. The plants run so cleanly that many times more dioxin is now released from home fireplaces and backyard barbecues than from incineration.

With all these innovations, Denmark now regards garbage as a clean alternative fuel rather than a smelly, unsightly problem. And the incinerators, known as waste-to-energy plants, have acquired considerable cachet as communities like Horsholm vie to have them built.

Denmark now has 29 such plants, serving 98 municipalities in a country of 5.5 million people, and 10 more are planned or under construction. Across Europe, there are about 400 plants, with Denmark, Germany and the Netherlands leading the pack in expanding them and building new ones.

By contrast, no new waste-to-energy plants are being planned or built in the United States, the Environmental Protection Agency says — even though the federal government and 24 states now classify waste that is burned this way for energy as a renewable fuel, in many cases eligible for subsidies. There are only 87 trash-burning power plants in the United States, a country of more than 300 million people, and almost all were built at least 15 years ago.

Instead, distant landfills remain the end point for most of the nation’s trash. New York City alone sends 10,500 tons of residential waste each day to landfills in places like Ohio and South Carolina.

“Europe has gotten out ahead with this newest technology,” said Ian A. Bowles, a former Clinton administration official who is now the Massachusetts state secretary of energy.

Making ISKCON Temples Eco-Friendly

Making ISKCON Temples Eco-Friendly By Nirguna dasi

His Holiness Bhakti Rasamrita Swami (previously H. G.Devamrita Das) spoke this past month at the ICC meetings (a Conference of ISKCON leaders) about the need for ISKCON temples and projects, in India, to consider implementing environment friendly standards.
Maharaj feels that Nature, as much as everything else, belongs to Krishna. As devotees, we should try in every way to counter or at least not add to the present environmental degradation.
Maharaj has surmised his ideas for ISKCON temples to adopt in the paper posted below.
Making ISKCON Temples Eco-Friendly
As a well-known and world-wide spiritual institution with a large member of followers, ISKCON is aware of its responsibility to the environment. In pursuance of this responsibility, we wish to formulate strategies for a step-by-step progression in the level of eco-friendliness of our Temples and other projects in India, leading to the setting up of practical standards of compliance. The culmination of course, will be “Green Temples”. Participation or suggestions from temples and projects outside India are most welcome.
In considering eco-friendliness, the following would need to be considered:
1.MATERIALS:
(For construction, interiors, kitchen and other equipment, packing and storage, stationery, clothing and other personal effects etc.)
2.ENERGY:
(For lighting, heating, cooking, transportation, domestic and other appliances, etc.)
3.WATER:
(Conservation, Recycling, Harvesting rain-water)
4.METHODS:
(For conserving water or for cooking, or for saving energy or for building structures and so on.)

5.WASTE MANAGEMENT:
(For solid and liquid waste)
6.FOOD:
(e.g. Organic foods, cooking mediums, utensils, fuels, packed foods, preferred and avoidable types of food, etc.)
7. TREES/GREENERY:
(For different purposes. Encouraging the use of plants indigenous to the local or geographical region.)
8.HEALTH:
(Being aware of health hazards of eco-unfriendly practices)

9.AUDIT:
(Current levels of usage vs ideal standards)
10.CREATING AWARENESS:
(Educating devotees about the need for being more eco-friendly)

These proposals are not intended to be compulsory requirements. Nevertheless, we urge all our temples and projects to follow certain minimum standards of compliance. We highly encourage and if possible will reward movement up the scale to higher standards of eco-friendliness. It will be left to the inspiration and motivation of individual Temples to adopt the standard.
Therefore, we wish to set up practically do-able, relatively simple, cost-effective and reviewable standards. This will be a basic list of do’s and don’ts of sorts.
We propose that this be done in FIVE LEVELS.
Level One will be the bare minimum standard that we expect every Temple to follow. This should be very easy to implement. (For e.g. Not using plastic bags, cups and glasses, conserving water etc.)
Level Five will be the highest standard. This would qualify for a genuinely “Green Temple” status in an urban setting.
There could be Level Six and Seven, it possible, for projects in rural areas, where higher standards are feasible.
We do not, as a rule, intend to obtain Eco-Friendly Certification from well known external institutions. (Of course, individual Temples may do so, if they wish). The certification that we intend for our Temples is our internal certification
Anyone interested in contributing their time and efforts, providing information or expertise are encouraged to please assist in this project. If anyone is, or knows of environment experts who may be able to help with a blueprint for an eco friendly or Green Temple, please do contact me:

Thank you.

Building A Green Economy




Click here to read the full article from award-winning economist Paul Krugman at the New York Times.

If you listen
to climate scientists — and despite the relentless campaign to discredit their work, you should — it is long past time to do something about emissions of carbon dioxide and other greenhouse gases. If we continue with business as usual, they say, we are facing a rise in global temperatures that will be little short of apocalyptic. And to avoid that apocalypse, we have to wean our economy from the use of fossil fuels, coal above all.
But is it possible to make drastic cuts in greenhouse-gas emissions without destroying our economy?

Like the debate over climate change itself, the debate over climate economics looks very different from the inside than it often does in popular media. The casual reader might have the impression that there are real doubts about whether emissions can be reduced without inflicting severe damage on the economy. In fact, once you filter out the noise generated by special-interest groups, you discover that there is widespread agreement among environmental economists that a market-based program to deal with the threat of climate change — one that limits carbon emissions by putting a price on them — can achieve large results at modest, though not trivial, cost. There is, however, much less agreement on how fast we should move, whether major conservation efforts should start almost immediately or be gradually increased over the course of many decades.

In what follows, I will offer a brief survey of the economics of climate change or, more precisely, the economics of lessening climate change. I’ll try to lay out the areas of broad agreement as well as those that remain in major dispute. First, though, a primer in the basic economics of environmental protection.

From Avatar to Amazon

From the New York Times

VOLTA GRANDE DO XINGU, Brazil — They came from the far reaches of the Amazon, traveling in small boats and canoes for up to three days to discuss their fate. James Cameron, the Hollywood titan, stood before them with orange warrior streaks painted on his face, comparing the threats on their lands to a snake eating its prey.

André Vieira for The New York Times

The Arara tribe, who live along the Xingu River in Brazil, are among the indigenous peoples who oppose a proposed dam.

The New York Times

The Belo Monte dam could dry up part of the Xingu River.

“The snake kills by squeezing very slowly,” Mr. Cameron said to more than 70 indigenous people, some holding spears and bows and arrows, under a tree here along the Xingu River. “This is how the civilized world slowly, slowly pushes into the forest and takes away the world that used to be,” he added.

As if to underscore the point, seconds later a poisonous green snake fell out of a tree, just feet from where Mr. Cameron’s wife sat on a log. Screams rang out. Villagers scattered. The snake was killed. Then indigenous leaders set off on a dance of appreciation, ending at the boat that took Mr. Cameron away. All the while, Mr. Cameron danced haltingly, shaking a spear, a chief’s feathery yellow and white headdress atop his head.

In the 15 years since he wrote the script for “Avatar,” his epic tale of greed versus nature, Mr. Cameron said, he had become an avid environmentalist. But he said that until his trip to the Brazilian Amazon last month, his advocacy was mostly limited to the environmentally responsible way he tried to live his life: solar and wind energy power his Santa Barbara home, he said, and he and his wife drive hybrid vehicles and do their own organic gardening.

“Avatar” — and its nearly $2.7 billion in global tickets sales — has changed all that, flooding Mr. Cameron with kudos for helping to “emotionalize” environmental issues and pleas to get more involved.

Now, Mr. Cameron said, he has been spurred to action, to speak out against the looming environmental destruction endangering indigenous groups around the world — a cause that is fueling his inner rage and inspiring his work on an “Avatar” sequel.

“Any direct experience that I have with indigenous peoples and their plights may feed into the nature of the story I choose to tell,” he said. “In fact, it almost certainly will.” Referring to his Amazon trip, he added, “It just makes me madder.”

Mr. Cameron is so fired up, in fact, that he said he was planning to go back to the Amazon this week, this time with Sigourney Weaver and at least another member of the “Avatar” cast in tow.

The focus is the huge Belo Monte dam planned by the Brazilian government. It would be the third largest in the world, and environmentalists say it would flood hundreds of square miles of the Amazon and dry up a 60-mile stretch of the Xingu River, devastating the indigenous communities that live along it. For years the project was on the shelf, but the government now plans to hold an April 20 auction to award contracts for its construction.

Stopping the dam has become a fresh personal crusade for the director, who came here as indigenous leaders from 13 tribes held a special council to discuss their last-ditch options. It was Mr. Cameron’s first visit to the Amazon, he said, even though he based the fictional planet in “Avatar” on Amazon rain forests. Still, he found the real-life similarities to the themes in his movie undeniable.

The dam is a “quintessential example of the type of thing we are showing in ‘Avatar’ — the collision of a technological civilization’s vision for progress at the expense of the natural world and the cultures of the indigenous people that live there,” he said.

Mr. Cameron said that he was writing a letter to President Luiz Inácio Lula da Silva urging him to reconsider the dam and that he would press for a meeting with the president. “They need to listen to these people here,” he said.

Mr. Cameron, 55, first encountered the cause in February, after being presented with a letter from advocacy organizations and Native American groups saying they wanted Mr. Cameron to highlight “the real Pandoras in the world,” referring to the lush world under assault in his movie.

Atossa Soltani, executive director of Amazon Watch, who accompanied him on his trip last month, said Mr. Cameron lit up at the idea of learning more, saying he had grown up in the Canadian woods and had even logged thousands of hours underwater exploring the world’s oceans.

As for Mr. Cameron’s Amazon adventure, it got off to a rocky start. The boat he traveled to the village in flooded when a hose became disconnected. Mr. Cameron chipped in, grabbing a plastic bucket to help bail for a few hours in the searing midday heat, he and others on the boat said.

Many of the indigenous leaders he was planning to meet with had never heard of him before, much less seen his movie. All they knew was that “a powerful ally” would be attending their gathering, Ms. Soltani said.

So, the night before Mr. Cameron and his wife, Suzy Amis, arrived with three bodyguards, a dozen or so villagers gathered in the house of José Carlos Arara, the chief of the Arara tribe here, to watch a DVD of “Avatar.”

“What happens in the film is what is happening here,” said Chief Arara, 30.

The morning after Mr. Cameron’s party arrived in the village, Chief Arara led them on a walk through the rain forest. Mr. Cameron, almost mirroring the enraptured scientists in his movie, was calm but wide-eyed, peppering the chief with questions about the local fauna and flora and traditional indigenous ways. In seconds, the chief showed how he could fashion ankle braces from leaves to help him scale an açaí tree.

The leaders then invited Mr. Cameron to participate in their meeting. He sat at a small wooden school desk as they made speeches condemning the impending dam and the Brazilian government. Mr. Cameron seemed to tear up when some leaders said they would be willing to die to stop the dam.

Finally, Mr. Cameron was asked to speak. He stood and complimented the leaders on their unity, saying they needed to fight off efforts by the government to divide them and weaken their resistance.

“That is what can stop the snake; that is what can stop the dam,” he said.

A rush of applause swept through the crowd. When the real snake fell from the tree, the director seemed unfazed. After clearing it away, indigenous leaders thanked him with gifts. One gave him a spear, another a black and red necklace of seeds. A third, Chief Jaguar from the Kaiapo nation, one of Brazil’s most respected, gave him his headdress before the dances in Mr. Cameron’s honor began.

“It’s not like there is any pressure on me or anything,” he said, half-joking, moments before boarding the boat. “These people really are looking for me to do something about their situation. We have to try to stop this dam. Their whole way of life, their society as they know it, depends on it.”

Protecting Our Oceans

From Sigourney Weaver at the Huffington Post

On the 40th anniversary of Earth Day, at a time when our country's attention will be focused on what we need to do to protect our planet, I am honored to be in our nation's Capital to testify before Congress on an emerging environmental threat. I will be testifying before the Subcommittee on Oceans, Atmosphere, Fisheries, and Coast Guard of the Senate Committee on Commerce, Science and Transportation Committee on the topic of ocean acidification.

Scientists have known for decades that when carbon dioxide mixes with ocean water it creates an acid; this is textbook chemistry. But only recently did they begin to realize what this growing quantity of acid would mean for ocean life. This new understanding has some of the world's leading ocean scientists deeply concerned.

What they say is this: the oceans are 30 percent more acidic today than they were during pre-industrial times and, if we continue burning fossil fuels as we are now, we will double the ocean's acidity by the end of the century. Scientists fear many organisms may not survive so radical a shift in chemistry. And some of those organisms form the foundation of ocean food webs. If they perish, what happens to the tens of thousands of species further up the chain? What happens to our shellfish -- our oysters, clams, mussels -- that appear particularly vulnerable to ocean acidification?

I first had the opportunity to address this issue in the Senate last fall, when I screened a short documentary I narrated on this phenomenon called Acid Test, made by my friends at the Natural Resources Defense Council. And after my Senate testimony this Earth Day, I am thrilled to show it to our nation's policymakers once again -- this time for a group in the House of Representatives.

Like that other film I was in this year, Acid Test has had an amazing run of its own. It aired on the Discovery Channel, has been shown in film festivals nationwide, and was selected by the National Oceanic and Atmospheric Association to run in kiosks in major aquariums and museums across the country. If you haven't seen it yet, catch it online here.

More and more people -- at home and in the halls of Congress -- are learning about ocean acidification and what we can do to stop it. Thankfully, we have solutions that will not only fight ocean acidification, but climate change at the same time.

Our policymakers have the power to add to the legacy of Earth Day by taking action that will protect people and the planet. Along with millions of other Americans, I will be urging them to put aside their differences and begin America's transition to a clean energy economy that will increase our energy efficiency and invest in renewable power, while cutting carbon pollution. By passing strong clean energy and climate legislation, Congress has the power to move us toward clean energy, tackle climate change and protect our seas from acidification.

I hope you will join me in calling on our leaders in the Senate to act.

Masdar: Abu Dhabi's Carbon-Neutral City

By Tom Heap for BBC News on 28 Mar 2010
Masdar City aims to be powered solely by renewable energy sources.

From ISKCON News

The oil-rich United Arab Emirates is the last place you would expect to learn lessons on low-carbon living, but the emerging eco-city of Masdar could teach the world.

At first glance, the parched landscape of Abu Dhabi looks like the craziest place to build any city, let alone a sustainable one.

The inhospitable terrain suggests that the only way to survive here is with the maximum of technological support, a bit like living on the moon.

The genius of Masdar - if it works - will be combining 21st Century engineering with traditional desert architecture to deliver zero-carbon comfort. And it is being built now.

Masdar will be home to about 50,000 people, at least 1,000 businesses and a university.

It is being designed by British architects Foster and Partners, but it is the ruler of Abu Dhabi, Sheikh Khalifa bin Zayed Al Nahyan, who is paying for it. And it will cost between £10bn ($15bn) and £20bn ($30bn).

Renewable energy

The architects are turning the desert's greatest threat - the sun - into their greatest asset.

Kaled Awad, director of the Masdar project

They have built the biggest solar farm in the Middle East to power the city and to offset the inevitable burning of diesel and baking of cement in construction.

They are also experimenting. One project involves a circular field of mirrors on the ground, all reflecting towards a tower in the middle.

That, in turn, bounces the light down in a concentrated beam about a metre (3ft) wide to produce heat and drive generators.

But I was told firmly not to wander over and feel the warmth, as it could fry me in seconds.

The international team of engineers have real pride in their work.

This is more than building to them, it is a lab bench with the freedom to get it wrong, and Masdar's chief architect Gerard Evenden loves the concentration of expertise: "What Abu Dhabi is beginning to generate is the Silicon Valley of renewable energy."

Keeping cool

The Emirates have seen one of the world's most spectacular building booms paid for by oil and made tolerable by air conditioners, which also depend on oil to feed their vast appetite for energy.

Lunar technology has begun to influence our thinking

But Masdar will have to be low temperature and low carbon.

Part of the solution is apparent the moment you walk in. And you do "walk in" because this is a city surrounded by a wall, a defined boundary.

Unlike the upward and outward sprawl of Dubai or Abu Dhabi, Masdar is compact like ancient Arab cities.

Streets are narrow so buildings shade each other, and the walls and roofs of buildings will do their bit to shed heat too.

The vertical faces are dressed with screens which look like a terracotta mesh. They keep the sun out but let the breeze in.

And as architect Gerard Evenden says: "Lunar technology has begun to influence our thinking."

One idea being tested is using a thin foil surface covering, a gas or vacuum blanket, to keep the heat out. It is an idea dreamt up for a moon base.

To encourage a breeze, wind towers are being built, drawing draughts through the streets without using energy.

Masdar will still use electricity for gadgets, some air conditioning and, most crucially, to desalinate sea water but, when it comes to power, the city has a simple mantra: "Only use energy when you have exhausted design."

Driverless vehicles

Conventional cars must be checked in at the city gates and then you can choose between the oldest and newest modes of transport.
Map of United Arab Emirates

At street level, it is all pedestrianised and the planners have done their best to keep the city compact and foot-friendly.

But if fatigue overtakes you, then slip down a level and meet the Personal Rapid Transit or podcars.

These driverless vehicles are guided by magnetic sensors, powered by solar electricity, and they stop automatically if an obstacle appears. They are programmed to go where you ask.

Kaled Awad, director of the Masdar project claims: "The quality of air will be better than any other street in the Gulf and in the world, and that alone will bring you safety, health and happiness."

The future success of the project will be clear to see.

On top of the wind tower, there will be a beacon betraying the city's actual energy use: red for too much, blue for just right.

It will be 45m (147ft) up and visible for miles around so, when Masdar is finished in five to 10 years' time, we will all know if it is in the red.
