This completely overstates the problem, is not supported by the evidence, and is exactly the kind of alarmism that undermines genuine climate science.

An AMOC slowdown or even collapse does not trigger an ice age. Full glacial periods are driven by orbital forcing, not ocean circulation alone.

The evidence points to regional cooling of a few degrees in parts of Western and Northern Europe, not rendering everything north of France uninhabitable.

Past ice sheets advanced over millennia under much colder global conditions than today, not on human timescales.

Even severe AMOC scenarios would be major and costly disruptions, not close to Europe being wiped off the map.
