Just seen a video on the North Atlantic Oscillation, and for the first time I’ve got an idea about a potential mechanism that transitions us into the ice-age. More important, this gives an idea of the timing … a few decades … indeed perhaps as long as a century before the ice-age “latches in”. In other words, we could experience conditions suggesting we are heading to another ice-age for a decade, and then return to the inter-glacial.
Still very tentative, but it’s starting to go together.
