"It's so hot, even parts of the Arctic are on fire ," reports Vox, citing wildfires in Sweden, while Greece "has declared a state of emergency as raging forest fires have killed at least 81 people and injured more than 190."But heat-related disasters are happening around the world. In Japan 86 people have been killed by heatstroke , while another 23,000 people have been hospitalized -- about half of them over the age of 65 -- in a heat wave forecast to continue for another two weeks. "Japan hit 106 degrees on Monday, its hottest temperature ever," reports the Associated Press, adding that "So far this month, at least 118 of these all-time heat records have been set or tied across the globe."

In Europe, nuclear power plants in Finland, Sweden, and German were forced to cut electricity production because high temperatures heated the seawater needed to cool reactors In northern California 38,000 people fled their homes as an 80,900-acre wildfire spread through the Shasta-Trinity area.
