Southern Québec is warming twice as rapidly as the rest of the world due to the progressive loss of snow cover. An average annual warming of 3 C to 6 C is expected by the end of the century.
The report projects an increase in mean temperatures and hot extremes across the continent. Worryingly the rate of temperature increase across the continent exceeds the global average.

New Zealand’s climate has been changing in line with global trends over the last century, warming by 1.1°C. But unless we curb emissions fast, we can brace for more extreme downpours and droughts.
Australia may warm by 4°C or more this century, the IPCC has found. As these IPCC authors explain, there is no going back from some changes in the climate system.
As rivers run dry in the Rocky Mountains and the West, it’s easy to wonder where all the snow you see on mountain peaks goes. Some of it ends up in the air, but researchers aren’t sure how much.
Not every extreme weather event is caused by climate change, but heat waves that were once ridiculously improbable are showing up more often. Just ask Portland.
Scientists studied charcoal layers in the sediment of lake beds across the Rockies to track fires over time. They found increasing fire activity as the climate warmed.
