What the Arctic’s rapid transition into a ‘new climate’ looks like | CBC News
By 2100, the Arctic will likely be ice-free for three to four months of the year; fall and winter temperatures for most of the Arctic Ocean will be 16 to 28 degrees warmer; and rainfall will replace snowfall, with an extension of the rainy season by two to four months each year compared to conditions in the 20th century — if greenhouse gas emissions stay up.
In the next 10 to 40 years, if emissions continue at a high rate, we could see a new climate, statistically, for air temperatures in the fall and winter.
The study says these changes will have wide-ranging and enormous consequences that will affect ecosystems, water resource management, food planning and infrastructure.
