Die Herausforderung globaler Klimawandel
At least half of the global warming observed during the 20-super-th century of about 0.8°C is of anthropogenic origin and mostly due to enhanced atmospheric carbon dioxide levels in response to the burning of fossil fuels. The climate problem is therefore closely linked to the way we produce energy. Climate models predict a massive warming by the end of the century should global greenhouse gas emissions not be strongly reduced. The Intergovernmental Panel on Climate Change (IPCC) reports that the warming can amount to up to 4°C in a worst case scenario, which would be unprecedented in speed and extent in man's history. This can lead to an increase of extreme weather events and a rise of global sea level by up to 1m. A less known impact of increasing atmospheric carbon dioxide is ocean acidification, as the oceans take up large amounts of carbon dioxide. Ocean acidification potentially threatens marine life and global food production. Copyright 2010 die Autoren Journal compilation 2010, Verein für Socialpolitik und Blackwell Publishing Ltd.
