Study blames global warming for 75 percent of very hot days - San Jose Mercury News: "WASHINGTON -- If you find yourself sweating out a day that is monstrously hot, chances are you can blame humanity. A new report links 3 out of 4 such days to man's effects on climate.
And as climate change worsens around midcentury, that percentage of extremely hot days being caused by man-made greenhouse gases will push past 95 percent, according to the study published Monday in the journal Nature Climate Change.
Humans have not had as great an effect on heavy downpours, though. The Swiss scientists who did the study calculated that 18 percent of extreme rain events are caused by global warming. But if the world warms an additional 2 degrees Fahrenheit -- expected to happen around midcentury -- about 39 percent of the downpours would be attributed to humanity's influence, according to the study. That influence comes from greenhouse gases, mostly carbon dioxide from the burning of coal, oil and gas."
