Analysis: The White House's proposed overhaul of the Endangered Species Act is its latest end-run around Congress to undo one of the real success stories of the green movement
By any measure, it is a long way from the Park Avenue headquarters of JPMorgan Chase, the global investment bank that generated revenues of $100 billion last year, to the dusty streets of Kampala, Uganda, where a poor woman can buy a new cook stove for about $6.

Covering the coming eco-apocalypse can be depressing business. But Rob Kutner sees the good times in end times
It is a sign of the times that the craziest thing I have seen this week was not Daryl Hannah licking surplus fuel off the petrol cap (or whatever she would call it) of her 60s-era Chevrolet El Camino.
What senators McCain and Obama believe about U.S. energy policy matters - hugely. To fight global warming, the next President will oversee the transition to a new, green economy, which will result in one of the biggest business transformations of the 21st century and potentially one of the largest transfers of wealth since the creation of the income tax.
Ahead of next week's G8 summit in Japan, former British Prime Minister Tony Blair calls for a united front against global warming
I separate my paper and plastics. I take the train to work instead of driving, and I'm definitely going to buy a bunch of those screwy lightbulbs one of these weekends. And...well, when it comes to being green, I guess that's about it.
Global warming could destabilize "struggling and poor" countries around the world, prompting mass migrations and creating breeding grounds for terrorists, the chairman of the National Intelligence Council told Congress on Wednesday.

Analysis: Senators Joseph Lieberman and John Warner's Climate Security Act is the U.S.'s most serious attempt to reduce greenhouse gas emissions. Is it destined for failure?
Global warming is not a problem for the future. We're already feeling the catastrophic effects today. Question is, is it too late to do anything about it?
An influential coalition of Fortune 500 companies and environmental groups that was formed to support climate-change legislation has splintered over the Lieberman-Warner bill that is headed next week to the Senate floor.
It's hard to imagine why ExxonMobil shareholders are so unhappy. After all, the world's largest publicly-owned energy company rode the surge in oil prices to a record $40 billion in earnings last year, making it by far the most profitable Fortune 500 company. Shares are up 10% in the last year, while the S&P500 has fallen by just as much.
If one person can make a difference, Taylor Francis, 16, wants to be that person. He's taking the global warming warning door-to-door from the U.S. to China
A climate-change bill that has widespread support as it heads to the Senate floor will create an estimated $150 billion of new assets in the first year it takes effect. Between now and 2050, regulating greenhouse gases could easily generate $3 trillion worth in value in the United States.
Analysis: The US finally rules that global warming is indeed threatening the species' survival. Not that it will make any difference
(WASHINGTON) -- The Interior Department declared the polar bear a threatened species Wednesday, saying it must be protected because of the decline in Arctic sea ice from global warming.Interior Secretary Dirk Kempthorne cited dramatic declines in sea ice over the last three decades and projections of continued losses. These declines, he told a news conference, mean the polar bear is a species likely to be in danger of extinction in the near future.Kempthorne also said, though, that it would be "inappropriate" to use the protection of the bear to reduce greenhouse gases, or to broadly address climate change.Reflecting views recently expressed by President Bush, Kempthorne said the Endangered Species Act was "never meant to regulate global climate change."He said the decision to list the bear includes administrative actions aimed at limiting the impact of the decision on energy development and other climate related activities."This listing will not stop global climate change or prevent any sea ice from melt
The GOP candidate's global warming plan has its flaws. But he has engaged the issue, and that bodes well for the '08 campaign
Climatology was once a small and often overlooked branch of science. But important discoveries made as early as the 19th century have contributed to what is the most important field of scientific study in the world today. Listed below are some key dates in climate change history.

The Dems may be greener, but the GOP are no slouches. (A Republican created the EPA, after all.) And that's what the Earth needs: good government, not politics
In the coming years we face an unprecedented challenge -- to provide the means for global prosperity, growth and stability from a radically different set of energy sources.
If all goes according to plan, the business of buying and selling rights to pollute the atmosphere with carbon dioxide and other greenhouse gases - carbon trading, as it is known - will curb global warming and save the world. That is its only purpose. Along the way, a lot of people will get rich.

Or assuaging your concerns over the environmental impact of getting that produce to your kitchen by shopping locally instead?
Tree-hugging goes only so far. The modern-day breed of environmentalist has bigger, better, higher-tech solutions for fixing global climate change

True or False: China, India and other developing countries are exempt from the Kyoto Protocol
The general dialogue on adapting to a world affected by climate change by definition excludes the world's poorest people.

Two new studies show that biofuels aren't the solution to global warming -- and may even exacerbate the problem
A new study finds that rising temperatures are in danger of wiping out the king penguins of Antarctica
It's lunchtime on Sand Hill Road, and Al Gore wants answers. "How does the efficiency decline with latitude?" he asks. "What size community could be served by one plant? If a manufacturer like GE wanted to make smaller turbines, would the technology support a smaller scale?"

The government plans to delay its decision to put the polar bear on the endangered list until after it leases 30 million acres near Alaska for oil and gas drilling. What gives?

At the UN climate change summit in Bali, global deforestation -- an oft-forgotten source of CO2 emissions -- is finally getting attention
NRG Energy's David Crane can seem miscast sometimes in the role of a Fortune 500 CEO. He wears a child's blue Swatch with a shiny plastic band. He settles into a chair - even a boardroom chair - the way a teenager would, with one leg curled up under his body.
As the UN summit on climate change wraps up in Bali this week, details of any post-Kyoto strategy still remain largely unknown.
Ten years after Kyoto, nations are wrestling once again over climate change. But big questions remain to be answered
