Study: Global Warming Isn’t Causing More Wildfires

wildfiresA new study out of a Welsh university found there’s been no increase in “area burned or in fire severity for many regions of the world,” despite predictions global warming would cause more severe wildfires as temperatures rise.

In fact, researchers found “increasing evidence that there is overall less fire in the landscape today than there has been centuries ago.”

“Yet many consider wildfire as an accelerating problem, with widely held perceptions both in the media and scientific papers of increasing fire occurrence, severity and resulting losses,” Drs. Stefan Doerr and Cristina Santin of Swansea University in Wales, wrote in their study.

“However, important exceptions aside, the quantitative evidence available does not support these perceived overall trends,” they wrote.

The study comes as Canadian firefighters continue to put out a massive blaze in Alberta. For weeks, firefighters have been stamping out the Alberta fire, which forced 90,000 people out of their homes in Fort McMurray.

The fire’s consumed little over 2,000 square miles and shut down about half of the region’s oil production. People can expect to return to their homes in June depending on air quality and other factors.

It wasn’t long before liberal writers and environmentalists blamed the massive blaze on man-made global warming. Slate’s Eric Holthaus ran the headline “Wildfire Rips Through Canadian City, Forcing 80,000 to Flee. This Is Climate Change.”

“One thing that is certain is that this fire has a clear link to climate change,” he wrote. “Canada’s northern forests have been burning more frequently over recent decades as temperatures there are rising at twice the rate of the global average”

The New Yorker’s Elizabeth Kolbert wrote “it’s tough to pin any particular disaster on climate change, in the case of Fort McMurray the link is pretty compelling.”

“In Canada, and also in the United States and much of the rest of the world, higher temperatures have been extending the wildfire season,” she wrote. “Last year, wildfires consumed ten million acres in the U.S., which was the largest area of any year on record.”

    I always find it amazing how a raise of 0.8 degree in temperature is supposed to have these drastic effects. One source lists the normal seasonal temperature fluctuation for Fort McMurray as -17.3 C to 16.6 C for a change of 33.9 degrees. More extreme years the seasonal difference is -22.1 C to 23.2 C for a change of 45.3 degrees. Then we are supposed to believe that a warming of 0.8 degrees, or even a slightly more than this, causes these wild fires.

    All sorts of things have been blamed on this same small temperature raise from species extinctions to bleaching coral. It just doesn’t make sense. It is obvious that the political activists are grabbing onto any excuse they can find to justify their cause.

    Well considering 0.6 degrees of that supposed temperature rise is due to “adjustments” made to the data…
