FEP 17.2.6 Greenhouse effect

Global changes in climate and sea levels caused by a warming of the atmosphere may occur due to the release of gases, principally carbon dioxide but also methane, through human activities (e.g. burning of fossil fuels, forest clearance, industrial processes). If this effect becomes dominant, markedly warmer climate states are predicted for northern Switzerland. The general consensus is that anthropogenically induced climate forcing may delay but not prevent a next ice age.
