Germany in the midst of climate change

Based on the 4th Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) submitted in 2007 concerning the causes and impacts of global warming as well as options for mitigation, the scientific findings are unambiguous. In all likelihood, i.e. with a probability of over 90 percent, the rise in the mean global temperature since the mid-20th century is attributable for the most part to the anthropogenic increase in the concentration of greenhouse gases.
