Minimum CO2 price of $32 needed to curb warming, study shows
A global carbon price of at least $32 (24 euros) per tonne is needed by 2015 to apply an effective brake on global warming—almost five times today's European market rate, a study said Monday.
Sea-level rise drives shoreline retreat in Hawaii
Sea-level rise (SLR) has been isolated as a principal cause of coastal erosion in Hawaii. Differing rates of relative sea-level rise on the islands of Oahu and Maui, Hawaii remain as the best explanation ...

The relentless, weather-gone-crazy type of heat that has blistered the United States and other parts of the world in recent years is so rare that it can't be anything but man-made global warming, says a new ...
Drought, fires impact ability of Amazon to hold carbon dioxide
Fires in the Amazon could jeopardize the forest's ability to soak up carbon dioxide emissions even as deforestation there slows down, according to a Penn State geographer.
Climate panel: Warming 'extremely likely' man-made (Update 3)
Scientists now believe it's "extremely likely" that human activity is the dominant cause of global warming, a long-term trend that is clear despite a recent plateau in the temperatures, an international climate ...
Heat waves to become more frequent and severe, research says
Climate change is set to trigger more frequent and severe heat waves in the next 30 years regardless of the amount of carbon dioxide (CO2) we emit into the atmosphere, a new study has shown.
With climate change, today's '100-year floods' may happen every three to 20 years: research
Last August, Hurricane Irene spun through the Caribbean and parts of the eastern United States, leaving widespread wreckage in its wake. The Category 3 storm whipped up water levels, generating storm surges ...
Amazon inhales more carbon than it emits, NASA finds
