Biophysical Feedbacks on the Regional Climate System
Experiments with coupled atmosphere/biosphere models indicate that land degradation leads to a reduction in rainfall, evapotranspiration, soil moisture and runoff, and an increase in surface temperature and near surface winds. This talk discusses studies that have investigated the feedback of degradation in forest and other ecosystems on regional climate in the Sahel, the central U.S., South Am...
متن کاملThe remote impacts of climate feedbacks on regional climate predictability
Uncertainty in the spatial pattern of climate change is dominated by divergent predictions among climate models. Model di erences are closely linked to their representation of climate feedbacks, that is, the additional radiative fluxes that are caused by changes in clouds, water vapour, surface albedo, and other factors, in response to an external climate forcing. Progress in constraining this ...
متن کاملAtmospheric chemistry‐climate feedbacks
[1] We extend the theory of climate feedbacks to include atmospheric chemistry. A change in temperature caused by a radiative forcing will include, in general, a contribution from the chemical change that is fed back into the climate system; likewise, the change in atmospheric burdens caused by a chemical forcing will include a contribution from the associated climate change that is fed back in...
متن کاملOn the determination of climate feedbacks from ERBE data
[1] Climate feedbacks are estimated from fluctuations in the outgoing radiation budget from the latest version of Earth Radiation Budget Experiment (ERBE) nonscanner data. It appears, for the entire tropics, the observed outgoing radiation fluxes increase with the increase in sea surface temperatures (SSTs). The observed behavior of radiation fluxes implies negative feedback processes associate...
متن کاملFeedbacks on climate in the Earth system: introduction.
In the last century, the Earth has undergone a very fast and unusual change in the radiative forcing of its climate, resulting from human actions. This change in forcing has resulted not only mainly from rising concentrations of greenhouse gases, particularly carbon dioxide (CO2), but also from changes in the nature of the land surface and changes in the concentrations of aerosol particles in t...
