WEBVTT Kind: captions Language: en 00:00:00.030 --> 00:00:04.350 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 00:00:19.230 --> 00:00:22.699 want to know more go to nasa.gov.
