But where do we see the face of global warming? It's there, in the roll of the dice.
“It’s OK to talk about events when you discuss them in a proper scientific context,” says Michael Mann, director of the Earth Science Center at Penn State and creator of the famous “hockey stick” graph. “The climate models have predicted what we’ve now seen, which is a doubling in the rate at which we break all-time warmth records in the U.S. We’re breaking those records, over the past decade, at a rate of almost twice what we would expect from chance alone.”
In fact, more than 2,000 U.S. heat records were broken just in the past week. Climatologists argue that while there’s certainly nothing unexpected in periodic record-breaking temperatures, the rate at which these records are being broken year after year can’t be explained away by coincidence.
“There’s a randomness to weather, but what we’re seeing is loading of the weather dice to the point where sixes are coming up 10 times more often,” says Mann. “If you were gambling and you saw sixes coming up 10 times more often you’d start to notice. We are seeing climate change now in the statistical loading of these dice.”
