3) Summary: Wild fires have burned at least 10.6 million hectares of land across Canada between Jan 1 and July 15, 2023 (665 million tonnes of CO2):
As of July 15, 2023, wildfires have burned at least 10.6 million hectares — or around 19.2 million acres — of land across Canada since the start of this year, according to the fire agency. The acreage has surpassed the previous annual record from 1989, reported by the National Forest Database.
In 2021, forest fires totaling 4.3 million hectares produced approximately 270 million tonnes of greenhouse gases. As of July 15, 2023, we have a total about 270 millions tonnes x 10.6/4.3 = approximately 665 million tonnes of CO2 emitted this year (by this date).

b) WashPost: How the Canadian wildfire smoke could shift Americans’ views on climate by Justine McDaniel, June 11, 2023
The ‘power of direct experience’ can change attitudes on climate change, researchers say. But whether it spurs people to action is less clear.
c) CO2 is not the only greenhouse are emitted by forest fires:
While the vast majority of carbon emitted by wildland fires is released as CO2, CO, and CH4, wildland fire smoke is nonetheless a rich and complex mixture of gases and aerosols.
e) NewScientist: Wildfires across Canada have emitted record-breaking amounts of carbon By Alec Luhn, 2 June 2023
Carbon emissions from wildfires in Canada were the highest ever recorded in May, highlighting the growing risk of blazes earlier in the year
Emissions for the month reached 54.8 million tonnes, more than double the carbon emitted by wildfires in any May since estimates began in 2003,
