The consequences of global warming are now unavoidable, while climate catastrophes are likely to get worse. Those are the findings of a new report from the United Nations Intergovernmental Panel on Climate Change (IPCC). 

The earth is projected to surpass a heating threshold of 1.5 degrees Celsius. It’s at that point when serious climate events are expected to take place. All that is according to Michael Prather, a professor of earth system sciences at UC Irvine and a contributor to the IPCC report. 

“There's probably going to be environmental issues of insecurity and threats around the world because a lot of places will not be livable,” Prather tells KCRW. “When you exceed 40 degrees Celsius … people cannot work outdoors. And so we're basically going into a new world.”
