Here's a Discover magazine article I noticed a couple of days ago, containing a nice (but big) animation that shows how many days per year (parts of) the Arctic will be ice-free in the future if things keep going as they are:
If global warming continues unabated, humans are likely to completely remake the map of the Arctic in a few decades
Ice was in the news quite a lot last week. There was, for example, the news that Antarctica could be gaining, not losing, ice, at least for now.
But far to the north, some equally important news unfortunately got less attention. For the long and short of it, see the animation above.
I created it to portray in visual form what a study published last week has revealed: Unless we start reining in greenhouse gas emissions, “our projected impact on the climate system will change the face of Arctic sea ice,” says Katy Barnhart, who led the study while she was at the University of Colorado’s Institute for Arctic and Alpine Research. (Full disclosure: I’m a professor at the University of Colorado.)
The animation shows computer model simulations of how Arctic sea ice is likely to respond to continued human-caused warming. More specifically, it models how the number of days of open water change each year from 1920 to 2100 under a “business-as-usual” scenario. By 2100, according to the study, much of the Arctic has greater than 150 additional days of open water as compared with the pre industrial period prior to 1850.
