“This summer has turned into a real marathon,” said Michael Norton, director general of the Canadian Forest Service, on Friday, as the West of the country is about to go through a new episode of heat wave. This is almost equal to the annual emissions of Japan (equivalent to 1.12 billion tonnes of CO2 in 2021), the world’s fifth largest polluter, and more than the annual emissions of the entire global aviation sector in 2022 (nearly 0.8 billion tonnes of CO2). The thousands of historic forest fires in Canada alone this year have emitted the equivalent of more than a billion tonnes of carbon dioxide, unprecedented, Canadian authorities estimated on Friday. The megafires in Canada have emitted since the beginning of the year the equivalent of more than a billion tonnes of carbon dioxide, almost as much as Japan, the fifth polluter in the world, in 2021.
