The Obama administration's greenhouse gas ruling Monday was meant to send a warning to industry, the U.S. Congress, and the world: with or without a law, Washington will tackle global warming in a serious way.

The Environmental Protection Agency issued a final ruling that greenhouse gases endanger human health, allowing it to put limits on emissions even if U.S. lawmakers fail to pass a law to achieve the same objective.

These are the ramifications of the long-expected decision:

• Timing: as the EPA made its announcement, negotiators from nearly 200 countries met in Copenhagen to work toward a … Read more

LONDON--The head of the U.N.'s panel of climate experts rejected accusations of bias on Thursday, saying a "Climategate" row in no way undermined evidence that humans are to blame for global warming.

Climate change skeptics have seized on a series of e-mails written by specialists in the field, accusing them of colluding to suppress data which might have undermined their arguments.

The e-mails, some written as long as 13 years ago, were stolen from a British university by unknown hackers and spread rapidly across the Internet.

But Rajendra Pachauri, who chairs the Intergovernmental Panel on Climate … Read more

A few days after leaked e-mail messages appeared on the Internet, the U.S. Congress may probe whether prominent scientists who are advocates of global warming theories may have misrepresented the truth about climate change.

Sen. James Inhofe, an Oklahoma Republican, said on Monday the leaked correspondence suggested researchers "cooked the science to make this thing look as if the science was settled, when all the time of course we knew it was not," according to a transcript of a radio interview posted on his Web site. Aides for Rep. Darrell Issa, a California Republican, are also looking into … Read more

WASHINGTON--A key U.S. Senate environment committee approved a Democratic climate change bill on Thursday that would require industry to cut emissions of carbon dioxide and other greenhouse gases 20 percent by 2020 from 2005 levels.

The bill approved by the Environment and Public Works Committee will now become one of several initiatives in the Senate aimed at attacking global warming. But they are unlikely to produce legislation that would be voted on by the full Senate until next year at the earliest.

With Republicans boycotting the environment panel's measure, saying more analysis of the legislation was needed, 10 … Read more

Can a $1 billion help save the environment? George Soros hopes so.

The billionaire financier and philanthropist plans to invest part of his wealth on clean tech to fight global warming. In a speech at the Project Syndicate editors' forum in Copenhagen, Denmark, on Saturday, Soros gave the keynote address announcing his new plans.

Soros said he will invest $1 billion in clean-energy technologies and will provide $100 million--$10 million each year for the next 10 years--for the new Climate Policy Initiative, a watchdog-type foundation to promote measures to combat climate change.

Note: All information in this story, unless otherwise noted, is from the National Park Service's pamphlets on and in-park signs about climate change and Glacier National Park.

GLACIER NATIONAL PARK, Mont.--The small graphics on a single sign, deep inside this incredible natural treasure says just about all you need to know about the drastic effects of rapid and intense climate change on the park and what's inside it.

"With warmer temperatures and changes to the water cycle, Glacier National Park will be glacier-free by 2030," the sign reads. "These changes will also have consequences … Read more

The Environmental Protection Agency may have suppressed an internal report that was skeptical of claims about global warming, including whether carbon dioxide must be strictly regulated by the federal government, according to a series of newly disclosed e-mail messages.

Less than two weeks before the agency formally submitted its pro-regulation recommendation to the White House, an EPA center director quashed a 98-page report that warned against making hasty "decisions based on a scientific hypothesis that does not appear to explain most of the available data."

The EPA official, Al McGartland, said in an e-mail message (PDF) to a … Read more

Tim O'Reilly makes the most cogent argument I've yet seen on why we should believe in global warming and act accordingly, even if we don't fully buy into the hype: The downside to belief is quite small. The upside is quite big.

In other words, it's a near-perfect application of Pascal's Wager, as Tim points out:

In my talks, I've argued that climate change provides us with a modern version of Pascal's wager: if catastrophic global warming turns out not to happen, the steps we'd take to address it are still worthwhile. … Read more

Granted, summer (or spring) picnic season may seem like a long way away, but it will be time to break out the blanket and head to the nearest patch of grass before you know it. Since the local weather here in San Francisco this week has been on the warm side, I think it's never too early to look ahead. Those winter doldrums aren't going to last forever, and when they melt, parks and beaches will be filled with hungry people, and I plan to be one of them.

Having a nice chilled meal outdoors on a clear, … Read more
