Summary:
The Rossby Centre Regional Climate Model (RCA3) and the hydrological model HBV were linked to assess climate change impacts on water resources in the Pungwe basin until 2050. RCA3 was capable of simulating the most important aspects of the climate for a control period at the regional scale. At the subbasin scale, additional scaling was needed. Three climate change experiments using ECHAM4-A2, B2 and CCSM3-B2 as input to RCA3 were carried out. According to the simulations annual rainfall in 2050 would be reduced by approximately 10% with increasing interannual variability of rainfall and dry season river flow and later onset of the rainy season. The ECHAM4-A2 driven experiment did also indicate a slight increase of high flows.

Mistra-SWECIA Science seminar: The effects of different energy sources and technological progress on climate change
Fossil energy and technological progress are two important factors that potentially influence climate change. Today, the main source of energy is fossil energy, and its use generates CO2-emissions with global warming as result. Technological progress can however improve the energy efficiency and potentially lead to the implementation of alternative clean energy sources that may partially or fully...
