As smoky as the summer has been so far, scientists say it will likely be worse in future years because of climate change.
As the atmosphere dries, it, creating more fuel that burns easier, faster and with greater intensity. Then you add more lightning strikes from more storms, some of which are dry lightning strikes, said Canadian fire scientist Mike Flannigan at Thompson Rivers University in British Columbia. Fire seasons are getting longer, starting earlier and lasting later because of warmer weather, he said.
The type of fires seen this year in western Canada are in amounts scientists and computer models predicted for the 2030s and 2040s. And eastern Canada, where it rains more often, wasn't supposed to see occasional fire years like this until the mid 21st century, Flannigan said. Since about the 1950s, America pretty much got wildfires down to a minimum, but that hasn't been the case since about 2000.
