|Description=Climate change is considered to be one of the most important effects of human activities on the environment. Emissions from fossil fuels, industry, land use and land-use change have increased greenhouse gas concentrations and led to almost 1 °C rise in global mean temperature on pre-industrial levels ([[IPCC, 2007a]]; [[IPCC, 2013]]). The impacts are already visible and are expected to increase in the coming century. Without further action, mean global temperature could increase by 2.6 – 4.8 °C (5-95 percentile, RCP8.5) by the end of this century ([[IPCC, 2013]]). Climate change impacts manifest themselves in all world regions, and affect almost all aspects of human activity. | |Description=Climate change is considered to be one of the most important effects of human activities on 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?
