In climate news, new research finds a record-breaking heat wave in Siberia is directly linked to greenhouse gas emissions from human activity. The study by the U.K. Met Office finds temperatures in Russia’s Arctic this year were 5 degrees Celsius above historical averages. The report warns of the widespread melting of Siberia’s permafrost, and an explosion of populations of silk moths that have damaged forests, helping to spark massive Arctic wildfires.
Meanwhile, the United States is heading into a record-breaking heat wave, with forecasters warning nine out of 10 U.S. residents will experience high temperatures of 90 degrees Fahrenheit or more over the next week. Death Valley, California, reached 128 degrees Fahrenheit on Sunday — just one degree shy of the highest temperature ever recorded anywhere on Earth.
