Wildfires transform forests from carbon sinks into sources.

2023 Canada wildfires emissions have already doubled previous annual record https://perma.cc/83EG-VNCZ
Currently (3rd August 2023), the total wildfire carbon emissions from Canada are around 290 megatons, while the previous record registered in 2014 of 138 megatons.

Boreal fires, typically accounting for 10% of global fire carbon dioxide emissions, contributed 23% (0.48 billion metric tons of carbon) in 2021, by far the highest fraction since 2000. (from Record-high CO2 emissions from boreal fires in 2021)

Wildfires, which release about 90 Tg CO2 annually into the atmosphere over the continuous U.S., are an important factor for the carbon cycle in this region.
The wildfire emissions of CO2 in the contiguous U.S. are expected to increase by 50% by 2050 and be doubled by 2100 due to the greenhouse effect. (from CO2 Emissions from Wildfires in the U.S.: Present Status and Future Trends)

So again, don't play with fire! See previous post
