The devastating wildfires in northern Canada in recent years have climate consequences that go far beyond smoke and carbon dioxide released into the atmosphere, according to a new study co-authored by two NAU researchers. The study, which looked at the various effects of fire in northern Canada and Alaska, wasn't all bad news: The researchers found fires in Canada, when coupled with snowpack, have a net cooling effect. That cooling, however, isn't enough to outweigh the warming effects of permafrost carbon released into the atmosphere from fires in Alaska.
