Does anybody remember a book a few years ago titled “The Coming Global Superstorm” ByArt Bell and Whitley Strieber? Is was the basis for the disaster movie “The Day After Tomorrow.” Basically, the theory is that global warming will reach a point where the polar ice melt desalinates the water in the North Atlantic, causing the Nort Atlantic current to shift south. This then causes extremely cold air (now held above the greenhouse layer getting colder and colder) to drop mixing with very warm air from global warming causing extremely powerful storms of ice and snow. Possibly a new ice age. This isn’t it, but it could be a precursor like a tremor before a big quake or the smoking and rumbling of a volcano before it erupts. I’m not saying the theory is correct but read the book and see what you think.
