The US Department of Transportation’s pipeline safety division says the 800-mile trans-Alaska pipeline is corroded and poses a severe public safety and environmental risk.
Record droughts hit the Amazon's rain forests in 2005 and 2010. With climate models projecting more drying with global warming, researchers are keeping close watch for such extreme droughts.
For years researchers have watched plants and animals migrate to cooler quarters in response to global warming. But a new study suggests some plants are moving downhill, drawn by increased precipitation.
The seasonal cooling effect of light-reflecting snow and ice in the Northern Hemisphere may be weakening at twice the rate predicted by climate models, a new study shows, accelerating the impact of global warming.
A panel of weather and climate experts ranked the the Top 10 global weather and climate events of 2010. Voters considered the scope and unusualness of the event, its immediate human and economic impact, and whether it is emblematic of climate trends or variability. They voted during the first week of December, so the following weeks' extreme winter weather in Europe, which may have deserved a spot in the Top 10, received an honorable mention.
2010 tied as warmest year ever, NOAA climatologists say. Year's data are consistent with the notion that greenhouse gases from burning fossil fuels are contributing to global warming.
The study's leaders say rates of methane decomposition after the Gulf oil spill 'were faster than had ever been recorded in any other place on the planet.' Other scientists are cautious about the results.
The president's commission on the Gulf oil spill has roundly criticized BP's role in the disaster. But it's appearing less likely that the British oil giant will be charged with gross negligence.
It's not unheard of that birds fall from the sky or fish die off en masse – but all at once around the world? Hard cold snaps are emerging as a likely cause of some of the bird deaths and fish die-offs.
Hinkley, Calif., battled pollution of its ground water by chromium 6 in the 1990s – a case that inspired 'Erin Brockovich.' Now the substance has escaped its containment barrier.
Just days after more than 1,000 birds fall from the sky over Beebe, Ark., another batch of blackbirds has dropped in Pointe Coupee Parish, La. What's going on?
Verdant Power seeks license to build a plant with 30 underwater turbines in New York's East River. It would be the first of its kind in the US, expanding the nation's green energy resources.
Dead red-winged blackbirds, starlings, and grackles rained down on Beebe, Ark., on New Year's Eve, freaking out local residents. After 3,000 birds fall from sky, state biologists look for answers.
Hexavalent chromium is the pollutant at the heart of 'Erin Brockovich.' The movie recounts the legal battle waged by residents of Hinkley, Calif., who blamed exposure to the chemical for high rates of diseases.
The debate over how much oil remains in the Gulf and where it is continues as research groups, environmental organizations, and government scientists conduct separate missions.
If climate change leads to ice collecting in one general area in the Arctic Ocean, it might be enough to provide a last 'refuge' for many Arctic inhabitants, including polar bears.
Greenhouse-gas emissions worldwide must be cut to avoid a disappearance of summer sea ice in the Arctic, which is crucial to the polar bear.
There's an expanding rift between developed and developing countries over whether to extend the 1997 Kyoto Protocol goals for reducing greenhouse gas emissions beyond the 2012 limits.
If November and December temperatures stay relatively warm, 2010 could capture the record for warmest year, an early analysis shows. This year has also been marked by extreme weather events.
The two-week negotiations begin on Monday and carry far lower expectations than did last December's climate change talks in Copenhagen.
