NASA | Carbon All Around Us

The video discusses the significant role of vegetation and soils in storing carbon, which is three to four times more than the atmosphere. It highlights that the land surface absorbs a quarter of carbon emissions from fossil fuels. George Hurst, a professor at the University of Maryland and leader of NASA's carbon monitoring system, introduces technologies being developed to monitor and model carbon with precision, aiming to reduce uncertainties and support decision-making.

How much more carbon do Earth's vegetation and soils store compared to the atmosphere?

• Twice as much

• Three or four times as much

• The same amount

• Five times as much

What fraction of carbon emissions from fossil fuels is absorbed by the land surface?

• 1/2

• 1/4

• 1/5

• 1/3
