Predictions of Future Change Gallery

The different predictions of global mean temperature change obtained from 8 different climate models under the SRES A2 emissions scenario (one which assumes no significant action to combat greenhouse gas emissions).

The predicted warming over the 21st century due to business as usual greenhouse gas emissions scenario (IS92a) as reported by the HadCM3 climate model. The average warming in this model is 3.0 °C.

Conceptual assessment of the risks and impacts of global warming across five areas of concern as a function of increasing temperature, as interpreted by the Intergovernmental Panel on Climate Change in their Third Assessment Report.

The predicted change in global mean sea level in a range of climate models following a business as usual emissions scenario (IS92a). The grey bar at 2100 indicates the full uncertainty range.

The predicted change in Arctic sea ice between 1950 and 2050, according to a climate model run by the Geophysical Fluid Dynamics Laboratory.

Predicted increase in the maximum intensity that hurricanes and other tropical cyclones are likely to achieve under otherwise favorable conditions.
