"The United States will suffer a series of severe droughts in the next two decades, according to a new study published in the journal Nature Climate Change. Moreover, global warming will play an increasingly important role in their abundance and severity, claims Aiguo Dai, the study’s author."

"A federal investigation into two researchers who wrote a famous report on drowned polar bears is finally over, according to their lawyer. But the scientists still haven't been allowed to see a copy of the investigation report or its conclusions, says attorney Jeff Ruch of Public Employees for Environmental Responsibility."

About half of the carbon we are dumping into the atmosphere does not stay there and is instead taken up by the oceans and land. Were this not the case, scientists say, the earth would probably be warming far more rapidly. One of the biggest questions in climate science is: How long will that disposal service last?"

It's the latest fusillade in the ongoing battle over the basic facts of fracking in America."

"Richard Muller, a cantankerous but creative physicist at the University of California, Berkeley, who once derided climate change research, then dove in with his own reconstruction of terrestrial temperature changes and confirmed substantial warming, has now concluded that recent warming is 'almost entirely' human caused."
