Andrew Freedman outdid himself on Climate Central with an excellent overview of the scientific debate on the link between Arctic sea ice loss and a wavy jet stream causing weird and extreme weather. Coincidentally (?) there's an "extreme kink" in it right now that just caused the warmest December temperature ever measured at any site on the Alaskan Arctic Ocean shoreline region.

Freedman wrote the piece following the publication in Nature of a new paper - with Jennifer Francis as co-author - that claims that rapid Arctic warming has an influence on extreme summer weather events. The last couple of years a lot of pioneering research is being done in this area, which in my view is one of the most exciting and important scientific corners currently around. Which explains why more and more experts are keeping an eye on developments.
