1 00:00:00,000 --> 00:00:00,330 2 00:00:00,350 --> 00:00:02,720 Of all the CO2 that humans are emitting into the atmosphere, 3 00:00:02,740 --> 00:00:06,990 about half is being absorbed by the land and the oceans. 4 00:00:07,010 --> 00:00:10,620 To better understand the processes that control carbon emission and carbon uptake, 5 00:00:10,640 --> 00:00:13,080 NASA is working to develop realistic models that describe 6 00:00:13,100 --> 00:00:16,980 how carbon moves between the atmosphere, land and oceans. 7 00:00:17,000 --> 00:00:18,680 We combine a wealth of satellite data 8 00:00:18,700 --> 00:00:21,020 with a description of physical processes 9 00:00:21,040 --> 00:00:22,900 that control the carbon cycle. 10 00:00:22,920 --> 00:00:26,330 A whole lot of math and computer power in order to better understand 11 00:00:26,350 --> 00:00:30,530 how carbon is changing both today and in the future. 12 00:00:30,550 --> 00:00:34,013
