Ice Age Now: An “ocean chimney” the size of Tasmania is pumping huge amounts of heat into the atmosphere. Headlines call the hole “mysterious,” but it doesn’t seem all that mysterious to me. I think the heat is coming from underwater volcanic activity.
A huge hole – roughly 30,000 square miles or the size of the state of Maine – has been spotted in sea ice near Antarctica. Australian media notes that the hole, roughly 80,000 square kilometers, is the size of Tasmania.
The humongous hole, known as a polynya, was detected about a month ago.
