The Facts on Climate Change on "World Class with Michael McFaul"

Looking for a reliable source on climate change? Marshall Burke is an assistant professor in the Department of Earth System Science at Stanford University and an FSE fellow. He has studied climate change extensively throughout his career. He tells FSI Director Michael McFaul how the world has already warmed one degree Celsius since pre-industrial times, causing more extreme weather events, a small rise in sea levels and a greater amount of carbon dioxide in the atmosphere. There is virtually no disagreement among scientists that the world is warming, he says, and the vast majority of scientists agree that humans are causing the change. Unless we reduce our emissions, the world will warm four to five degrees in the next century, making bad weather worse and gradually increasing average temperatures everywhere. If this happens, the world's GDP will decrease by about 20 percent, causing massive disruption to the world's economy.
