While record-breaking heat scorched the Pacific Northwest in June 2021, parts of Europe and Siberia also saw early-summer temperatures climb. On June 23, ground stations in Moscow measured an air temperature of 34.8°C (94.6°F)—the city’s hottest June temperature on record. A second region of warm surface temperatures is visible toward the east, along the Arctic coast in Siberia. Both the offshore wind and the early heatwave helped to reduce the amount of sea ice in the Laptev Sea. So far, the record-low sea ice appears to be localized to the Laptev Sea.
