Interesting weather effects --

The blue bands running southeast from the Great Lakes are lake effect snow, caused by cold air blowing over the open water surface, picking up moisture, and dumping it over land downwind. Later in the year, after the lakes have frozen over, there is no more lake effect snow.
The waters around Greenland have been seeing decreasing ice coverage and warmer air temperatures over the last few decades, which leads to a similar effect.
Knowledge of this is nothing new. It is not likely, however, to show up in any climate-change denier twitter feed.
