In response to the disruptions of climate change, plants will emit greater levels of fragrant chemicals called biogenic volatile organic compounds, a major scientific review finds. The problem is too complex to yet gauge many of the consequences.

Former Alaska Gov. Sarah Palin called studies supporting global climate change a "bunch of snake oil science" Monday during a rare appearance in California, a state that has been at the forefront of environmental regulations.

Sen. Blanche Lincoln's ascendancy to the Agriculture Committee chairmanship was a bad omen for passage of climate-change legislation in 2010 due to her close ties to agricultural producers and processors seen as major contributors of greenhouse gases.

Recent winters have been ending earlier than ever before, according to a new assessment of Britain's wildlife that reveals global warming could be disrupting the delicate balance of nature.

Researchers funded by a $170,000 federal grant are focusing on Sarasota and its Gulf of Mexico shoreline to demonstrate how low-lying coastal communities grow more vulnerable to storm surge as sea levels rise. And they are rising, scientists say.

German Enivronment Minister Norbert Röttgen has caused a rift in Chancellor Angela Merkel's coalition government by suggesting that it drop plans to extend the lifetimes of the country's 17 nuclear power stations.

Energy experts are thinking through how to replace coal that's burned in American power stations. One alternative is to burn plants, because they can produce fewer greenhouse gas emissions. And in the Midwest, there's talk of growing millions of acres of grass for biomass.

Phillips has invested more than 4 billion euros ($5.47 billion) to ride the clean-tech wave. The company is betting on a shift in the lighting market, away from inefficient incandescent light bulbs and toward long-life energy-efficient light-emitting diodes, or LEDs.

Finnish researchers called for a revision of climate change estimates Monday after their findings showed emissions from soil would contribute more to climate warming than previously thought.

Business-as-usual agricultural expansion to meet biofuel production targets for 2020 will take a heavy toll on Brazil's Amazon rainforest in coming years, undermining the potential emissions savings of transitioning from fossil fuels to biofuels.

Washington's climate policy analysts from environmental groups are quietly abandoning – at least temporarily – the once sacrosanct notion that nations must agree to legally binding emission targets.

Dr. Rajendra K. Pachauri and the IPCC are now under intense scrutiny, facing accusations of scientific sloppiness and potential financial conflicts of interest from climate skeptics, right-leaning politicians and even some mainstream scientists.
