00:00:00,350 --> 00:00:02,720
Of all the CO2 that humans are emitting into the atmosphere,

2
00:00:02,740 --> 00:00:06,990
about half is being absorbed by the land and the oceans.

3
00:00:07,010 --> 00:00:10,620
To better understand the processes that control carbon emission and carbon uptake,

4
00:00:10,640 --> 00:00:13,080
NASA is working to develop realistic models that describe

5
00:00:13,100 --> 00:00:16,980
how carbon moves between the atmosphere, land and oceans.

6
00:00:17,000 --> 00:00:18,680
We combine a wealth of satellite data

7
00:00:18,700 --> 00:00:21,020
with a description of physical processes

8
00:00:21,040 --> 00:00:22,900
that control the carbon cycle.

9
00:00:22,920 --> 00:00:26,330
A whole lot of math and computer power in order to better understand
