\begin{abstract}
We're Radley Horton, Lamont Associate Research Professor at Columbia
University's Lamont-Doherty Earth Observatory in Palisades, New York and
Sarah Doherty, Senior Research Scientist at the Joint Institute for the
Study of the Atmosphere and Ocean at the University of Washington in
Seattle. We were both Lead Authors on the recent Climate Science Special
Report (http://www.globalchange.gov/content/cssr), which focused on
climate change in the U.S. and part of the Fourth National Climate
Assessment. We're here to talk about how our climate is changing, what
causes it, and what to expect in the years ahead. We're looking forward
to your questions! We'll be back at 1pm ET to answer your questions, ask
us anything! The AGU AMA series is conducted by the Sharing Science
(sharingscience.org) program. Sharing Science: By scientists, for
everyone. More at sharingscience.agu.org.%
