Climate Warming - National Summer Precipitation Scenario: 2050

A simulation of projected changes in summer (June to August) precipitation from the period 1961 to 1990 to the period 2040 to 2060 for Canada is shown on this map. Projected precipitation changes would not be evenly distributed geographically. Summer patterns show regions with both increases and decreases in precipitation. Warmer surface temperature would speed up the hydrological cycle at least partially, resulting in faster evaporation and more precipitation. The results are based on climate change simulations made with the Coupled Global Climate Model developed by Environment Canada.
