A simulation of projected changes in June to August mean temperatures from the period 1975 to 1995 to the period 2040 to 2060 is shown on this map. According to this projection, there would be typically more warming over land than over oceans, at higher latitudes than at lower latitudes, and in winter compared to summer. 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.
