What is the greenhouse effect and which gases are involved? How do man-made greenhouse gas emissions cause change in the earth’s atmosphere and what can still be done to limit global warming?
Global mean surface air temperature has risen gradually since the age of industrialisation. It is now accepted as scientifically proven that we humans are responsible for a significant part of this increase. Hence one speaks of anthropogenic, or man-made, climate change.
Climate is described in terms of mean values, characteristic extreme values, and frequency distributions of meteorological parameters such as air pressure, wind, temperature, cloud cover, and precipitation over a certain period of time and larger area.
