Writing for Time, Ciara Nugent doesn't pull any punches: "The World Has Been On Fire For the Past Month," reads her headline. But it's an assertion she backs up with photos from locations scattered across the northern hemisphere, from Greece and Italy to Siberia and our own shores. That includes Turkey, which has no operational firefighting planes, and northern Finland, which only sees wildfires infrequently and last month suffered its worst wildfire in 40 years. In the US, Greenville, California, has been turned into a "moonscape" by the Dixie fire. But Nugent expresses particular worry about Siberia due to the double whammy created when fires accelerate permafrost melting, which releases methane into the air—leading to a cycle of greenhouse gases pushing up temps and making conditions for such fires more favorable.
