Is the extreme weather we have been experiencing related to climate change? Is climate change caused by humans? To answer these questions, the author interviews "Kevin Trenberth, head of the Climate Analysis Section at the National Center for Atmospheric Research in Boulder, Colo. The climatologist, a leading member on the Intergovernmental Panel on Climate Change, shared the Nobel Peace Prize in 2007 when it was awarded to the IPCC."
The thing that is most clear is the increasing temperatures. We can look to sea levels rising, Arctic sea ice and glaciers melting. ...All this is consistent with this warming. There’s also pretty good evidence that when it rains, it rains harder than it used to especially across the U.S. That’s due to anthropogenic climate change, and that’s only going to get bigger.
