Connection between Increasing China Smog and Melting Sea Ice

We set a record low in the ice extent this winter. Could the loss of ice be causing the air quality to get worse in China?

The Arctic and Antarctica saw record low ice area over the northern hemisphere winter, and now there’s new research that seems to show a link between the Arctic ice loss and increased air pollution in China. With dark, heat-absorbing water now replacing what was once bright and very reflective ice, the energy balance of the atmosphere has to change, and that change translates to changing weather patterns. There is quite a bit of research into this now, with more questions than answers, but I think this paper will be noticed. Dr. Jennifer Francis at Rutgers is also a leader in the investigation of this. Obviously, this is of high interest to synoptic meteorologists (like me).

Science magazine has a good non-geek explainer piece about the paper that’s well worth a read. This is a good example of why scientists prefer the term climate change to global warming. The former is a much more descriptive term for the changes we are making to the Earth’s climate.
