Description:
The accumulation of greenhouse gases in the atmosphere over the past century is projected to cause a warming of the Earth. limate change predictions vary by region and terrestrial biosphere response and feedbacks will be ecosystem specific. orests play a major role in the earth's carbon cycle through assimilation of CO2, storage of carbon, emission of greenhouse gases. imulation models have been employed to examine the possible responses to climate change of global forest ecosystems. ajor shifts in forest species distribution and composition are predicted in response to projected climate change within the next 60-80 years. he range of some species is expected to shift dramatically in biomes worldwide. avanna type vegetation could replace some forests under the more extreme climate change predictions in temperate latitudes. The ultimate response end feedbacks of forests will be influenced by the direction and magnitude of climate change, site quality and other stress agents. stablishment of new forests and implementation of management practices could potentially be used to sequester significant amounts of atmospheric CO2. reliminary evidence suggests the terrestrial biosphere could be managed to reduce accumulation of greenhouse gases in the atmosphere and mitigate negative impacts of climate changes.
