Global wildfires emitted about 2.8 billion metric tons of CO2 equivalent in 2023, roughly sketching the scale of what smoke, heat, and land cover loss can add up to. At the same time, high intensity fire behavior is shifting how landscapes recover, from increased carbon loss to doubled tree mortality in the western US. This post pulls together the key global and regional signals, so the patterns behind the acreages and emissions are easier to see across years and continents.
Key Takeaways

- Global wildfire burned area averaged 350 million hectares annually from 2003-2022
- Global fire radiative power increased by 15% from 2001-2021, indicating hotter fires
- In 2023, global wildfires emitted approximately 2.8 billion metric tons of CO2 equivalent
- Siberia's 2021 wildfires burned 18 million hectares, releasing 500 million tons of CO2
- Boreal forests accounted for 60% of global fire carbon emissions in 2021

- Projections indicate 30% increase in global burned area by 2050 under RCP4.5
- Fire weather index globally increased 25% since 1970
Wildfires are burning more area and releasing more carbon, with longer, hotter seasons reshaping ecosystems and costs worldwide.
