2
00:00:01,250 --> 00:00:04,290
There is carbon all around us. 

3
00:00:04,310 --> 00:00:05,780
The trees, grasses, crops,

4
00:00:05,800 --> 00:00:09,000
all the vegetation and soils on the Earth's surface store carbon.

5
00:00:09,020 --> 00:00:12,280
About three or four times as much in the atmosphere. 

6
00:00:12,300 --> 00:00:12,500


7
00:00:12,520 --> 00:00:17,080
As a whole, the land surface is absorbing one quarter of the carbon we emit from fossil  fuels.

8
00:00:17,100 --> 00:00:19,350
Will it continue?

00:00:19,370 --> 00:00:21,430
I'm George Hurtt, professor at University of Maryland

10
00:00:21,450 --> 00:00:24,130
and leader of NASA's Carbon Monitoring System. 

11
00:00:24,150 --> 00:00:28,100
We are developing technologies to monitor and model carbon with sufficient precision 

12
00:00:28,120 --> 00:00:31,130
to reduce uncertainties and support decision making.
