Fires in non-tropical forests have steadily emitted more and more carbon each year since 2001, releasing an additional half a billion tons of carbon dioxide each year, a new study has found.

Carbon dioxide emissions from forest fires have surged 60% globally since 2001, as more and bigger blazes tore through fast-warming regions outside the tropics, according to a new

A major new study reveals that carbon dioxide (CO2) emissions from forest fires have surged by 60% globally since 2001, and almost tripled in some of the most climate-sensitive northern boreal forests.
