MacKinnon says Arctic sea ice could be gone by next year and only develop during the winter months.
Previous research suggested that sea ice can partly recover in the winter following a strong summer melt because thin ice grows faster than thick ice. However, new findings indicate that heat from the ocean is overpowering this stabilising effect – reducing the volume of sea ice that can regrow in the winter. This means that sea ice is more vulnerable during warmer summers and winter storms.
“However, what we’ve found now is that in the Barents Sea and Kara Sea regions, this stabilising effect is being overpowered by ocean heat and warmer temperatures that are reducing the ice growth in winter.”
This new process is called Atlantification, meaning that heat from the Atlantic Ocean carried to higher latitudes is causing the edge of the sea ice to retreat.

June 4, 2021
Utah’s governor is calling for a weekend of prayer to help with the state’s ongoing drought.
Much of the Western half of the United States is in the grip of a severe drought of historic proportions. Conditions are especially bad in California and the Southwest, but the drought extends into the Pacific Northwest, much of the Intermountain West, and even the Northern Plains.
Drought emergencies have been declared. Farmers and ranchers are suffering. States are facing water cutbacks. Large wildfires are burning earlier than usual. And there appears to be little relief in sight.
