|Description=Climate change is generally considered among the most serious of human interferences in the environment. Emissions from fossil fuels, industry, land use and land-use change have increased greenhouse gas ([[HasAcronym::GHG]]) concentrations and caused the global mean temperature to be almost 1 oC above pre-industrial levels ([[IPCC, 2007a]]) . The impacts of climate change are already visible today and are expected to become much stronger during this century and beyond, if no action is taken and if global mean temperature could increase by 4 to 6 °C ([[IPCC, 2007a]]). Climate change impacts manifest themselves in all world regions, and practically affect all aspects of human activity. | |Description=Climate change is generally considered among the most serious of human interferences in the environment.

Key policy issues
- What would be the impact of global climate change in this century without additional mitigation policies and measures?
- To what extent would the various scenarios to significantly reduce net greenhouse gas emissions lead to a reduction in climate change?
- To what extent does the uncertainty of geographical patterns in temperature and precipitation change influence future climate impacts and response strategies?
