A change in the type, distribution and coverage of vegetation may occur given a change in the climate. Some changes in climate may result in increased precipitation and warmth, resulting in improved plant growth and the subsequent sequestration of airborne CO 2. Though an increase in CO 2 may benefit plants, some factors can diminish this increase.
Cumulative land-use change contributions to CO 2 emissions, by region. [32]: Figure SPM.2b Local vegetation cover impacts how much of the sunlight gets reflected back into space , and how much heat is lost by evaporation. For instance, the change from a dark forest to grassland makes the surface lighter, causing it to reflect more sunlight.
