But during the longer - lasting ones like the Mongol invasion there was enough time for the forests to re-grow and
absorb significant amounts of carbon.
The oceans
absorb a significant amount of the carbon that enters the atmosphere, creating carbonic acid that makes it hard for marine life to survive and threatens the entire oceanic food chain.
Not exact matches
However, overlapping bands in the lower troposphere where water vapor dominates will keep
carbon dioxide from
absorbing any
significant amount of radiation — in the lower troposphere itself.
Plants naturally
absorb carbon dioxide and release oxygen, but certain plants also eliminate
significant amounts of benzene, formaldehyde and / or trichloroethylene.
The fact that organic agriculture systems also
absorb and retain
significant amounts of carbon in the soil has implications for global warming, Pimentel said, pointing out that soil
carbon in the organic systems increased by 15 to 28 percent, the equivalent
of taking about 3,500 pounds
of carbon dioxide per hectare out
of the air.
However, the data also showed that
significant amounts of carbon dioxide were being
absorbed by the waters near the ocean surface.
According to a new study
of 28,000 measurements collected between 2000 and 2006 and analyzed by NOAA's CarbonTracker system, only about a third
of the
carbon dioxide is
absorbed by
carbon sinks such as the soil and forests; a large portion
of it ends up in the atmosphere - but that still leaves a
significant amount unaccounted for.Interestingly, the CarbonTracker found
carbon emissions to be highest in the Midwest; that single region released more
carbon dioxide than any other country - except Russia, China, India and,
of course, the U.S.
Carbon dioxide was found to be most readily
absorbed east
of the Rocky Mountains and in northern Canada.
