Climate change scenarios for desert areas by 2050
Hugo Ahlenius, UNEP/GRID-Arendal
In desert areas by 2050, the majority of the temperature increase, according to the NCAR-CCSM3 model (and the IPCC SRES A2 scenario), will occur in the Northern Sahara, western Australia and in the inland deserts of North America. The precipitation will increase closer to the equator, but with large decreases primarily in Australia.
