At the Copenhagen Climate Change Conference, Google.org, Google's philanthropic arm, announced a cloud-based method for analyzing deforestation around the world in a much more up-to-date manner than previously possible.

Using Google's terabytes of satellite imagery, it lets scientists look back over time at any location in the world and see how the forest has changed. Going beyond visual comparisons, it uses the power of cloud computing to do actual measurement of deforestation. Much more rapid analysis of the images than is possible on a single desktop computer pinpoints locations of most recent activity. This lets authorities locate … Read more

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

Coca-Cola said Thursday that it will eliminate a major greenhouse gas in its new vending machines and coolers, raising the bar for climate-friendly refrigeration in the food and beverage industry.

Coke's Chief Executive Muhtar Kent said that the company, which sells everything from soda and juice drinks to water, will replace hydrofluorocarbon, also known as HFC, in its new vending machines and coolers by 2015.

While Coke's 10 million vending machines, coolers and other refrigeration equipment around the world keep its drinks chilled, they also are the biggest contributor to the company's carbon footprint.

Together the refrigeration … Read more

Google Earth and California Gov. Arnold Schwarzenegger announced Wednesday that Google is developing a tool to map out disturbing scenarios of how California can be affected by climate change.

The project comes out of a collaboration with the California Natural Resources Agency, Schwarzenegger, and the Stockholm Environment Institute (SEI), an organization funded by the California Energy Commission and Google.org.

"There is a serious bottleneck in delivering relevant information, much of which is map-based, to decisionmakers in a manner that allows them to turn climate change research results into effective climate change adaptation decisions and policies," according to … Read more

OSLO--Promises of greenhouse gas curbs by China and the United States brighten prospects for next month's U.N. climate summit but leave big tangles over cash, rich nations' emissions cuts, and how to tie down a legal treaty.

"This is clearly some progress on the Copenhagen road," Frank Jotzo, deputy director of the Australian National University's Climate Change Institute, said of pledges by the world's top two emitters to tackle global warming.

But he noted China's goal of slowing its rising emissions by 2020 was voluntary and President Barack Obama's plan to cut … 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

U.S. Senator John Kerry said on Tuesday he will try to "outline" a compromise climate control bill before December's international global warming conference and U.N. Secretary-General Ban Ki-moon gave an upbeat assessment of Washington's intentions.

"From what I heard today, there is great support in the Senate for action on climate change," Ban told reporters following a meeting with a small group of senators in the U.S. Capitol to encourage them on.

Ban repeated a prediction that the December 7-18 U.N. global warming summit in Copenhagen will not produce a final deal … Read more

The world faces a surge in energy costs, as well as in planet-warming carbon emissions, unless it can swiftly agree a climate change deal, the International Energy Agency said Tuesday.

Arguing strongly for a global deal at the U.N. Climate Change summit in Copenhagen in December, the IEA said use of fossil fuels will increase quickly if policies remained unchanged.

Without an international agreement on climate change, the ratio of energy spending to gross domestic product for the largest consumer countries would double by 2030.

The world would have to spend an extra $500 billion to cut carbon emissions … Read more

People at green-technology companies will likely keep an eye on next month's global climate change negotiations in Copenhagen but they aren't betting their businesses on the outcome.

Research and events company Cleantech Group on Thursday released an analysis called "Why Cop15 Doesn't Matter," referring to the 15th conference of international climate change talks scheduled to start December 7 in Copenhagen.

With numerous political and economic issues complicating the picture, it would be surprising if a major breakthrough pact emerged next month. But whether there is a binding agreement won't have an immediate impact on … Read more
