Scientists Now 95% Sure Climate Change Is Our Fault

And say sea could rise 3 feet by end of century, according to leaked IPCC report

(Newser) - OK, we did it. A new UN report from the Intergovernmental Panel on Climate Change has found "it is extremely likely that human influence on climate caused more than half of the observed increase in global average surface temperature from 1951 to 2010." That "extremely likely" is...

Truth About Last Ice Age Found in Antarctic Ice

Study: Turns out warming happened around the same time everywhere

(Newser) - December 2011 saw the end of a five-year effort to recover the longest ice core ever drilled by the US. About half of the more than two-mile core, taken from the West Antarctic Ice Sheet Divide, has been now been analyzed, taking scientists back through 30,000 years of annual...

Climate Change Moving Marine Life 4 Miles Every Year

Could be fatal for some

(Newser) - Climate change is really jerking animals around—literally. A new international study has found marine life is moving an average of 4.3 miles towards the poles each year, while land animals are moving about 3,280 feet, as ocean and air temperatures rise, the Guardian reports. "We knew...
