00:00:05,070 --> 00:00:09,070
2018 was the fourth hottest year on record.
3
00:00:09,070 --> 00:00:13,000
4
00:00:13,000 --> 00:00:17,070
Earth has been warming up for decades.
5
00:00:17,070 --> 00:00:21,070
6
00:00:21,070 --> 00:00:25,000
7
00:00:25,000 --> 00:00:29,000
The last five years are the hottest five years on record…
8
00:00:29,000 --> 00:00:33,070
9
00:00:33,070 --> 00:00:37,070
And the last four were all more than 1 degree Celsius
10
00:00:37,070 --> 00:00:41,000
warmer than the 19th Century average.
11
00:00:41,000 --> 00:00:45,000
A warmer climate contributes to…
12
00:00:45,000 --> 00:00:49,000
melting polar ice and mountain glaciers,
13
00:00:49,000 --> 00:00:53,000
rising sea levels,
14
00:00:53,000 --> 00:00:57,000
more severe droughts,
15
00:00:57,000 --> 00:01:01,000
longer fire seasons.
16
00:01:01,000 --> 00:01:05,000
17
00:01:05,000 --> 00:01:09,070
NASA and NOAA work together to study the temperature from weather stations,
18
00:01:09,070 --> 00:01:13,070
ships and buoys in the ocean, and Antarctic research stations.
19
00:01:13,070 --> 00:01:17,070
