GCSE Evidence for Climate Change
Changes in the pathway of the Earth around the Sun.
The period of geological time from about 2.6 million years ago to the present. It is characterized by the appearance and development of humans and includes the Pleistocene and Holocene Epochs.
A gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.
is a long-term change in the earth's climate, especially a change due to an increase in the average atmospheric temperature.
Suggest average world temperatures are increasing
are melting due to climate change. 90% of glaciers in Antarctica are retreating, melting glaciers at the poles could also affect ocean water movement.
have air bubbles that tell the composition of air from many years ago - shows a very strong link between CO2 concentrations and temperature
show climate change is happening, autumn starts later and spring comes earlier
