Blistering heat waves are proof of global warming, insists expert

The relentless, weather-gone-crazy type of heat that has blistered the US and other parts of the world in recent years is so rare that it can’t be anything but man-made global warming, a statistical analysis from a top government scientist says.

The research by a man often called the “godfather of global warming” says that the likelihood of such temperatures occurring from the 1950s through the 1980s was rarer than one-in-300. Now, the odds are closer to one-in-10, according to the study by Nasa scientist James Hansen. He says statistically what’s happening is not random or normal, but pure and simple climate change.

“This is not some scientific theory. We are now experiencing scientific fact,” Mr Hansen said.
