Impact of wildfire in Russia between 1998–2010 on ecosystems and the global carbon budget

Verified estimates of wildfire area and related carbon emissions in territories of Russia are reported for the period of 1998–2010. It is shown that the average burnt area is estimated to be at 8.23 million hectares per year (uncertainty ±9.0%, confidence interval 0.9), and carbon emissions—121 Tg C...

Description
Summary:Verified estimates of wildfire area and related carbon emissions in territories of Russia are reported for the period of 1998–2010. It is shown that the average burnt area is estimated to be at 8.23 million hectares per year (uncertainty ±9.0%, confidence interval 0.9), and carbon emissions—121 Tg C yr −1 (±23%), with a significant interannual variability of these indicators. A quantitative characteristic of fire emissions by species is reported. Forests are a source of three quarters of all carbon emissions caused by wildfires. A significant acceleration of fire regimes is expected during the 21st century as a result of climate change in the country.
