My name is Gavin Schmidt and I'm a
climate scientists at NASA. 2015 was a

00:00:04.350 --> 00:00:07.080
record warm year.
That's partly because there's a big El

00:00:07.080 --> 00:00:11.070
Nino event ongoing in the tropical
Pacific, but it's mostly because there's

00:00:11.070 --> 00:00:14.610
a long term trend in temperatures that's
related to the increase in greenhouse

00:00:14.610 --> 00:00:19.230
gases. Particularly carbon dioxide that
comes from burning fossil fuels. If you
