Arctic Ocean could be ice-free for part of the year as soon as 2044

Arctic sea ice“It’s hard to imagine the Arctic without sea ice. But according to a new study by UCLA climate scientists, human-caused climate change is on track to make the Arctic Ocean functionally ice-free for part of each year starting sometime between 2044 and 2067. As long as humans have been on Earth, the planet has had a large cap of sea ice at the Arctic Circle that expands each winter and contracts each summer. The knowledge that sea ice is on the decline is not new: Satellite observations show that since 1979, the amount of sea ice in the Arctic in September — the month when there is the least sea ice, before water starts freezing again — has declined by 13 percent per decade.”
