00:00:00,010 --> 00:00:04,080
2017 was the second hottest year since 1880, when global measurements first became possible.

00:00:08,090 --> 00:00:12,100

00:00:12,100 --> 00:00:16,100
This continues a decades-long trend of global warming.

00:00:16,100 --> 00:00:20,120

00:00:20,120 --> 00:00:24,140
As the global climate continues to warm, polar ice melts,

00:00:24,140 --> 00:00:28,160
sea levels rise, and fire seasons burn hotter and longer.

00:00:28,160 --> 00:00:32,210

00:00:32,210 --> 00:00:36,220


10
00:00:36,220 --> 00:00:40,220
NASA continues to monitor Earth's temperature and its effects on weather and climate,

00:00:40,220 --> 00:00:44,240


12
00:00:44,240 --> 00:00:48,240
to better understand our home planet as an interconnected system.
