Climate change ignites in Canada –> The worst wildfire in Alberta's history has forced nearly the entire population of Fort McMurray, a town of 80,000 in the north of the province and the heart of tar sands country, to evacuate. Eric Holthaus writes for Slate.com: "The images from the scene are horrific. As people left the city, they heard explosions and often drove within a few feet of open flames. A gas station blew up. Radio stations were abandoned. Buildings burned… One thing that is certain is that this fire has a clear link to climate change."
