Potential collapse of the Gulf Stream
By 
This is the kind of thing that could accelerate the climate change emergency in a drastic and extremely destabilizing way:
A new study published Tuesday in the journal Nature, found that the Atlantic Meridional Overturning Current – of which the Gulf Stream is a part – could collapse around the middle of the century, or even as early as 2025.
Scientists uninvolved with this study told CNN the exact tipping point for the critical system is uncertain, and that measurements of the currents have so far showed little trend or change. But they agreed these results are alarming and provide new evidence that the tipping point could occur sooner than previously thought. . .
[Scientists] found “early warning signals” of critical changes in the AMOC, which led them to predict “with high confidence” that it could shut down or collapse as early as 2025 and no later than 2095. The likeliest point of collapse is somewhere between 2039 and 2070, Ditlevsen said.
“It’s really scary,” he told CNN. “This is not something you would lightly put into papers,” he said, adding, “we’re very confident that this is a robust result.”
De Menocal said the study results were “both surprising and alarming.”
It’s been clear for a while that the AMOC will weaken in the coming decades, he told CNN. In 2021, a study found the AMOC was showing signs of instability due to climate change.
But until now, we haven’t had a time frame.
Northern Europe could easily turn into Siberia under the right (wrong) circumstances, and the effects on North America would be devastating as well.
