Evidence of the impact of global warming on the environment is reviewed such as melting glaciers and sea ice and water levels in lakes. Its impact on the biological world and on human health is also reviewed. Agents responsible for the greenhouse effect, such as water vapour and fossil fuel combustion are discussed. Specific examples include automotive sources, coal-fired electrical generators and the Alberta tar sands. Computer modeling, often a target of those who choose to discredit the fact of global warming, is also dealt with.
