FactCheck - Climate Change: Canadian Forest & Wildfires Due To Human CO2 Emissions?
(click on to enlarge)
This article discusses the severe forest fire that is currently happening in the Fort McMurray area of Canada, which the article's author takes issue with those claiming the fire is due to climate change from human activities - i.e. human CO2 emissions, etc.
Claims that specific fires (and forest and wildfires overall) are due to human greenhouse gases have routinely been made since the 1988 testimony of NASA's top climate scientist, James Hansen, predicted that rapid and accelerating warming from GHG emissions would cause more severe and frequent weather events.
As a result of this Congressional testimony, the "consensus" climate experts then predicted that the "dangerous" human-caused warming would produce a significant trend increase of wildfires, especially in the northern hemisphere's boreal forests.
Although the globe has warmed since 1988 (not rapid, nor accelerating, see here and here), the trend for Canadian boreal forest fires has been the opposite of that predicted over the 27 years after the Hansen 1988 testimony.
The adjacent charts plots the number of Canadian forest fires and hectares burned. Clearly, the trends are declining, which suggests an inverse relationship with the level of atmospheric CO2 (ppm CO2 is the chart's right axis).
Despite those climate "experts" failed prognostications, the recent irrefutable empirical evidence indicates that the increased levels of atmospheric CO2 emissions are producing a greener and healthier biosphere, which actually may be more resistant to wildfires.
