"100°F about 70 miles north of the Arctic Circle today in Siberia. That's a first in all of recorded history. "Been watching the Siberian heatwave for months and it's beyond terrifying—already suffering what was expected in 2100 in a worst case scenario," said climate activist and conservationist Charlie Gardner.As the Guardian reported last week, "the freak temperatures [in Siberia] have been linked to wildfires, a huge oil spill, and a plague of tree-eating moths." On Sunday, the same location recorded a high temperature of 95.3 degrees (35.2 Celsius), showing the Saturday reading was not an anomaly," the newspaper reported.
