What is global warming and why is it happening? . Global warming is the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans, a change that is believed to be permanently changing the Earth's climate. Learning Objectives. :. To understand the evidence for and against global climate change- World and UK temperatures for the last 100 and 1000 years. To know the causes of global warming. To know the consequences of global climate change- social, economic, environmental and political consequences of global climate change and how they change the way we live. . Effects on Biodiversity.

Climate change can be discussed in short, medium and long timescales. . Short-term (recent) climate change is on a timescale of decades, an example would be global warming. . The medium-term (historical) timescale covers changes over the last few thousand years.. Some of the infrared radiation . passes through the atmosphere, . and some is absorbed and . re-emitted in all . directions by . greenhouse gas . molecules.

Climate change?. . “Whatever Nature has in store for mankind, unpleasant as it may be, men must accept, for ignorance is never better than knowledge.” Enrico Fermi 1938.. :.
