A simulation showing the projected changes in June to August mean temperatures from the period 1975 to 1995 to the period 2080 to 2100 is shown on this map. There would be typically more warming over land than over oceans, at higher latitudes than at lower latitudes, but the warming would be smaller in the summer than in the winter. Temperatures would generally increase as a consequence of the projected increase in greenhouse gas concentrations in the atmosphere. The results are based on climate change simulations made with the Coupled Global Climate Model developed by Environment Canada.
