Climate is a global issue. Model projections of climate change show increases in average global temperatures that range from 2℃ to 4℃ by the end of 2100. The difference in the estimate depends on global emissions scenarios, where the higher greenhouse gas (GHG) emissions lead to higher temperature increases.

As of 2021, we are on a high emissions trajectory, but if we are successful in lowering global emissions, future average global temperature change can be limited to 2℃, which is the target under international agreements like the Paris Accord.

For many people, a global change in average temperature of 2℃, may not seem like much. But changes in temperature, and other climate change effects such as precipitation and weather patterns, will not happen equally everywhere. Some regions will experience even higher temperature changes, such as the polar regions of the globe.

This means climate change is a particularly important issue for Canada!
