Climate Change: Plausible Worst Case Scenarios

Climate Progress has a great post up:

" * The Arctic could warm by up to 15.2 °C [27.4 °F] for a high-emissions scenario, enhanced by melting of snow and ice causing more of the Sun’s radiation to be absorbed.
* For Africa, the western and southern regions are expected to experience both large warming (up to 10 °C [18 °F]) and drying.
* Some land areas could warm by seven degrees [12.6 F] or more.
* Rainfall could decrease by 20% or more in some areas, although there is a spread in the magnitude of drying. All computer models indicate reductions in rainfall over western and southern Africa, Central America, the Mediterranean and parts of coastal Australia.
* In other areas, such as India, rainfall could increase by 20% or more. Higher rainfall increases the risk of river flooding.
* Large parts of the inland United States would warm by 15°F to 18°F."
