      I’m not good at explaining this, here’s the science on climate change

      Climate change and the developments it spurs carry the narrative of the Quaternary, the most recent 2.6 million years of Earth’s history. Glaciers advance from the Poles and then retreat, carving and molding the land with each pulse. Sea levels fall and rise with each period of freezing and thawing. Some mammals get massive, grow furry coats, and then disappear. Humans evolve to their modern form, traipse around the globe, and make a mark on just about every Earth system, including the climate.

      If there’s an AMOC collapse, one of the likely outcomes is literally The Day After Tomorrow. The science in that movie is surprisingly grounded in reality.

        Not even remotely accurate. It would cause notable changes and likely widespread famine but not anything as instantly apocalyptic as the film. Temperatures wouldn’t change dramatically aside from Northern Europe. The gulf stream’s effect on temperatures is smaller than people think.

        The bigger change globally speaking would be shifting precipitation patterns. This could lead to dramatic aridification of parts of Africa and India, and large increase in precipitation in North America. But it’s not going to trigger some kind of hemispheric ice age as depicted in the film.
