Melt extent over Greenland was well over 40% on June 12, 2019. The surface melt map that day (on the right) shows many coastal areas for which data are missing, as indicated by the grey color. As the June 13, 2019, NASA Worldview satellite image (underneath, right) shows, snow and ice in many coastal areas has melted away. Four nullschool images are added below. The first one shows air temperatures over Greenland as high as 22.7°C or 72.9°F on June 13, 2019, at 1000 mb. Also note the high temperatures visible over East Siberia and the East Siberian Arctic Shelf (ESAS). A second nullschool image shows that a temperature of 0.9°C or 33.5°F was recorded at the North Pole on June 15, 2019. Temperatures above the melting point of ice have been recorded at the North Pole for some time now. The third nullschool image shows that temperatures as high as 30.5°C or 86.8°F are forecast for June 19, 2019, near Tiksi, which is on the coast of Siberia where the Lena River flows into the Laptev Sea an...
