Canada has been affected by an ongoing, record-setting series of wildfires since March 2023.
Carbon dioxide emissions from the fires would continue to rise drastically, according to estimates by Chinese Academy of Science in a recent study.
It is worth noticing that extreme wildfires are becoming more common and increasingly affecting Earth's climate.
Wildfires are rapidly expanding into boreal forests with emerging warmer and drier fire seasons. Boreal fires, typically accounting for 10 percent of global fire carbon dioxide emissions, contributed 23 percent (or 0.48 billion metric tons of carbon) in 2021, by far the highest fraction since 2000, according to a research paper published in Science magazine.
The year 2021 was an abnormal year as North American and Eurasian boreal forests synchronously experienced their greatest water deficit. Increasing numbers of extreme boreal fires and stronger climate-fire feedbacks challenge climate mitigation efforts, read the paper titled "Record-high CO2 emissions from boreal fires in 2021."
