The Atlantic Meridional Overturning Circulation (AMOC) will shut down by about 2055.
“shutdown of the Atlantic Meridional Overturning Circulation (AMOC) is likely within the next 20-30 years, unless actions are taken to reduce global warming”Climate

Global temperature will reach +2°C above the 1880-1920 average by 2045.
“global warming in the next two decades is likely to be about 0.2-0.3 °C per decade, leading to global temperature +2 °C by 2045.”Climate
