Climate change could cause another 4 million square kilometers, or about 1.5 million square miles, of permafrost to disappear with every additional degree Celsius, or 1.8 degrees Fahrenheit, of warming, a new study suggests.

A UM study has found that tidal flooding has leaped by 400 percent in the last ten years thanks to climate change.
