Alexandra Heal in the Financial Times 9-10-22. "The Ancient subarctic forests at risk from climate change and war".  she says these forests are going fast due to global warming and fires.  They store lots of carbon-more than humans have released since 1870!    

Although much of the boreal is undeveloped, logging is rampant in parts of Canada and Siberia. More than 4,000 sq km of Canada’s ancient trees are cut down every year, according to the Natural Resources Defense Council. This destroys wildlife habitat and can also release carbon from the soil. An environmental research paper found last year that fires in Siberia were more frequent near felling sites.
