This page presents notes on scientific published articles related to Fires.
Article: "Warming and Earlier Spring Increase Western U.S. Forest Wildfire Activity."
  • Since 1970, large wildfire activity in western U.S. increased suddenly and markedly in mid-1980s.
  • Increase highly correlated to sub-regional responses to changes in climate.
  • Continuing frequency of large wildfires will result in carbon release, becoming a source rather than sink of carbon dioxide.

Article: "The Impact of Boreal Forest Fire on Climate Warming."
  • Short term (first year) effect of boreal forest fire is increased radiative forcing 34 Watts per metre squared of burned area.
  • Long term effect is decreased forcing by -2.3 Watts per square metre when averaged over 80 year fire cycle.
  • Future increases in boreal fire may not accelerate climate warming.
