The sizzling heat threatening lives and fueling wildfires this summer would have been virtually impossible without man-made global warming, scientists said on Tuesday.

The Algerian Defense Ministry said on Monday night that 10 soldiers died in the hardest-hit region of Bejaia. It added that 25 people were injured and evacuated to the closest hospitals.

Environmentalists have warned that wildfires may hasten the thaw of Siberian permafrost and peatlands, releasing carbon stored in the frozen tundra into the atmosphere.
