The Climate Atlas of Canada is an interactive tool that combines climate science, mapping and storytelling to bring the global issue of climate change closer to home for Canadians.
The Climate Atlas displays projections for two possible climate futures. Each assumes a different level of future greenhouse gas emissions, which leads to more or less global warming.
Emissions continue to increase at current rates.
This is the "business as usual" scenario, and assumes that world greenhouse gas emissions continue to increase at current rates through the end of the century. This large amount of greenhouse gas emissions results in more severe global warming. This is also called the "high carbon" future, and is based on the RCP 8.5 emissions scenario.
Greenhouse gas emissions slow, peak mid-century, and then drop rapidly.
This scenario assumes that greenhouse gas emissions increase until about 2050 and then rapidly decline. This decline in emissions leads to less severe global warming than the alternative “business as usual” or high carbon scenario. This is also called the "low carbon" future, and is based on the RCP 4.5 emissions scenario.
The "baseline" maps and data describe climate conditions in the recent past. The values were generated by climate models and have been shown to accurately represent observed records (when averaged over time periods such as seasons or years). Importantly, the baseline period does not mean "before global warming": our climate had already warmed quite a bit by the 1970s.
This period of time begins in just a couple of years, and we'll be in the middle of it in about 20 years. Most Canadians will see these changes come to pass.
This period of time begins in about 30 years, and we'll be in the middle of it in about 45 years. Younger Canadians will likely experience all of these changes, and many older Canadians will at least see them begin.
Select the type of information you want displayed using the icons below the map.
You can also choose between more and less extreme warming, and how far into the future you want to go.
Once you've selected some climate info, you can choose a square region or a municipality to get more detailed information.
The icons on the map indicate there are videos available about that area. Hear more about climate change from people all over the country.
