Is that possible? Can you describe the chain of events that would lead to that?
Seems vanishingly unlikely to me, on the face of it, but I admit I am not read up on all the possible doomsday scenarios.

Human extinction seems very unlikely, but the collapse of the infrastructure that allows creation of the infrastructure that allows modern life? That could be much more likely, particularly when you factor in military conflicts as well as purely climate-based changes and losses.
It's quite hot around there. Wet bulb temperatures often near the edge of survivability outdoors.
It's worse now with 1-1.5C warming. If we don't stop, and we get to 3-5C warming, this could lead to large scale migration to Europe in pursuit of liveable climate. And warming won't stop unless we stop emitting greenhouse gases.
