John Kerry: Ukraine crisis is bad, but 'wait until you see' flood of climate refugees

John Kerry, the U.S. special presidential envoy for climate, said the refugee "problem" in Ukraine pales in comparison to the refugee crisis that will come if climate change is not addressed.

"We’re already seeing climate refugees around the world," he said. "If you think migration has been a problem in Europe in the Syrian War or even from what we see now, wait until you see 100 million people for whom the entire food production capacity has collapsed."
