\begin{abstract}
Hello! I'm Kris Karnauskas, faculty member at the University of Colorado
Boulder's (http://www.colorado.edu) Department of Atmospheric \& Oceanic
Sciences (http://www.colorado.edu/atoc/) and Cooperative Institute for
Research in Environmental Sciences (http://cires.colorado.edu/). I'm
also an editor of AGU's Journal of Geophysical Research-Oceans
(http://tinyurl.com/ztaob5k). I lead the Oceans \& Climate Lab
(http://www.colorado.edu/oclab/), which aims to understand what makes
the climate system tick, the role of the ocean in climate, and what are
the effects of climate change on marine ecosystems and human society. My
team just published a study about some ongoing changes in the Pacific
Ocean near the equator (http://tinyurl.com/gohynr9), and what they mean
for penguins hanging in the balance. With one of the strongest El Nino
events in recorded history peaking just last month, it has been an
incredibly exciting year to be an oceanographer and climate scientist!
Talk to you soon! I'll be back at 12 pm EST (9 am PST, 7 pm UTC) to
answer your questions, ask me anything!%
