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.
A new report finds that the much maligned Copenhagen Accord could give negotiators at global warming talks in Cancun, Mexico, next week something to build upon.
Interior Secretary Ken Salazar met with the offshore drilling industry Monday in Houma, La. The event highlighted building tensions in the wake of the Gulf oil spill.
That's the good news heading into Cancun global warming talks Nov. 29. The bad news is that the carbon dioxide emissions aren't likely to stay down for long.
In the wake of the Gulf oil spill, Obama said science would guide energy policy, but some claim that the White House made a political 'edit' in a drilling report. House hearings could explore the issue.
The guidelines are intended to help states and industry evaluate the cost and kind of technologies that would best reduce greenhouse gases.
Operators of the Deepwater Horizon rig, getting ready to move on to the next job, appeared to let their attention drift at a critical moment, hints the National Commission on the BP Deepwater Horizon Oil Spill and Offshore Drilling.
Amid hearings on the cause of the Deepwater Horizon disaster, government scientists, academics, and those most affected by the Gulf oil spill are at odds over the extent of its effects.
A new energy revolution – similar to shifts from wood to coal to oil – is inevitable as climate change and oil scarcity drive a global search for sustainability in power production. But even the promise of renewable energy holds drawbacks.
Everyone has been conditioned to flick off lights when they leave a room – or, if they forget, to tromp dutifully back to turn them off. Many such energy-saving actions have become routines that make us feel very green, very much the global good citizens helping to reduce dependence on fossil fuels. We don't really know how Al Gore would do on this quiz. But if you take it and ace it, you might feel a little competitive with the man who won the Nobel Peace Prize for his efforts to counter climate change by reconsidering the energy choices behind the problem. Take our quiz and find out how much you really know about your energy use:
The US Postal Service and other government agencies are trying to make their transportation fleets more eco-friendly.
Biodiversity researchers warn that 20 percent of vertebrate species are threatened with extinction, largely because of human damage to habitats. But conservation efforts, they say, are effective.
As firms prepare to launch the space tourism business, one study warns that the soot from the suborbital crafts' hybrid rocket motors could collect in the stratosphere and warm the poles.
Mayor Daley has proposed the idea of privatization, after Chicago's own 'blue bag' recycling program flopped. But the next mayor may be the one to decide.
Utilities may close up to 1 in 5 coal-fired power plants after tougher EPA air pollution rules go into effect next year, Wall Street investment banker Credit Suisse recently reported. Coal power is losing its price edge to natural gas, too.
An expiring tax credit is pushing homeowners to boost energy efficiency. Can it work for you?
