Gulf Stream Collapse: Why Europe Could Freeze

Europe has a problem. While the continent sits pretty far north, it actually has pretty mild temperatures overall. But that could change as the two things that keep Europe so pleasant could be collapsing: the Gulf Stream and the Atlantic Meridional Overturning Circulation (AMOC). Both of these work in tandem to distribute warm water from the south to the northern region which then influences the temperatures of Europe. So what happens if the Gulf Stream and AMOC do collapse? And are we seeing it happen right now?
