Simulations of Climate Change for IPCC AR4
2-Meter Temperature
The different presumptions for emissions of greenhouse gases and aerosols according to the different scenarios result in different projected changes of the 2-meter temperature. The warming varies regionally. The warming over the continents is, for example, much stronger compared with the temperature increase over the oceans. This typical warming pattern appears within a few decades, with different strengths for the different scenarios, though. Consequently, the warming over land is much stronger compared with the global mean temperature increase.
The animations show the running 5- years mean of the "Ensemble Mean" for the IPCC SRES scenarios A2, A1B and B1.
