Uncertainty requirements in radiative forcing of climate change.

The continuing increase in atmospheric carbon dioxide (CO2) makes it essential that climate sensitivity, the equilibrium change in global mean surface temperature that would result from a given radiative forcing, be quantified with known uncertainty. Present estimates are quite uncertain, 3 +/- 1.5 K for doubling of CO2. Model studies examining climate response to forcing by greenhouse gases an...

Radiative forcing of climate by historical land cover change

[1] The radiative effect of changing human land-use patterns on the climate of the past 300 years is discussed through analysis of a series of equilibrium and transient climate simulations using the UVic Earth System Climate Model. Land-surface changes are prescribed through varying land cover type, representing the replacement of natural vegetation by human agricultural systems from 1700 to 19...

Radiative forcing and climate response

We examine the sensitivity of a climate model to a wide range of radiative forcings, including changes ofsolar irradiance, atmospheric CO2, 03, CFCs, clouds, aerosols, urface •bedo, and a "ghost" forcing introduced at arbitrary heights, latitudes, longitudes, easons, and times of day. We show that, in general, the climate response, specifically the global mean temperature change, issensitive to...
