Abstract

In the last one-and-a-half century the rapid growth of the world's population and the development of technology caused an immense increase of energy use. Most of this energy was and still is produced by burning fossil fuels. The direct consequence has been an increase of the atmospheric CO2 level by more than 35% since 1750, the beginning of the industrial era. In this presentation the effect of greenhouse gases in the Earth's radiation balance will be discussed. A second question that will be addressed is to what extent changes in atmospheric radiative transfer affect the global mean temperature. Observational and model studies show that the climate sensitivity in response to a doubling of the CO 2 concentration is 2-4.5 K. Thirdly, t he attribution of observed global average temperature change to potential causes will be discussed as to compare the relative importance of natural and anthropogenic factors.
