\begin{abstract}
Hi Reddit! My name is Gavin Schmidt. I am a climate scientist and
Director of the NASA Goddard Institute for Space Studies. I work on
understanding past, present and future climate change and on the
development and evaluations of coupled climate models. I have over 100
peer-reviewed publications and am the co-author with Josh Wolfe of
``Climate Change: Picturing the Science,'' a collaboration between
climate scientists and photographers. In 2011, I was fortunate to be
awarded the inaugural AGU Climate Communications Prize and was also the
EarthSky Science communicator of the year. I tweet at @ClimateOfGavin.
My name is Reto Ruedy and I am a mathematician working as a Scientific
Programmer/Analyst at the Goddard Institute for Space Studies. I joined
the team that developed the GISS climate model in 1976, and have been in
charge of the technical aspects of the GISS temperature analysis for the
past 25 years. You can read more about the NASA 2015 temperature
analysis here (or here, here, or here). You can also check out the NOAA
analysis --- which also found 2015 was the warmest year on record. We'll
be online at 1 pm EST (10 am PST, 6 pm UTC) to answer your questions ---
Ask Us Anything! UPDATE: Gavin and Reto are on live now (1:00 pm EST)
Looking forward to the conversation. UPDATE: 2:02 pm EST - Gavin and
Reto have signed off. Thank you all so much for taking part!%
