Community Notes

This is very provocative paper suggesting the the changes in the sea ice and the changes in the springtime snow cover in Canada, Alaska, etc. are having fundamental changes in the propagation of weather systems across North America.  The carry away is that systems are moving more slowly, leading to more extreme events.  This would also suggest changes in the Arctic Oscillation, because the Arctic Oscillation is important in how weather systems move across the country.
