Dr. Kevin Trenberth is a Distinguished Senior Scientist in the Climate Analysis Section at the National Center for Atmospheric Research. In this interview, Dr. Trenberth explains the effect anthropogenic climate change is having on our weather systems, especially regarding the catastrophic record-breaking flooding in Houston this month, as well as the Category 5 Hurricane Irma that wrecked havoc on Florida and the Florida Keys. This summer, tens of millions of people across Asia have been displaced due to massive flooding, and practically the entire Pacific Northwest of North America has been on fire.
