"The systems affected by tipping points include the Atlantic meridional overturning circulation (AMOC), which includes the Gulf Stream system; if this system was weakened or even interrupted, Europe would face extreme winter cold and more winter storms, among other things. There is a chance that the AMOC tipping point may be passed and the system will start to collapse by the middle of the century. That would entail enormous consequences for social, political, economic and technical systems in the following decades."
