A Real Gulf?

The 'Gulf stream' is technically known as the Atlantic Meridonal Overturning Circulation (AMOC). This flow of warm water has major effects on weather systems throughout the globe (https://www.theguardian.com/environment/2021/aug/05/climate-crisis-scientists-spot-warning-signs-of-gulf-stream-collapse). The AMOC currents are now at their slowest for at least 1,600 years. Scientists are worried that this 'tipping point' (a change that cannot be reversed) is nearing shutdown. If that happens, the effects would be catastrophic. The scientists predict that India, South America and West Africa would fail to get the rains, needed to grow crops. Storms are likely to become much more frequent in Europe. The sea level would increase on the East coast of the USA, flooding major cities. The Amazon rainforest and the Antarctic ice sheets would be further endangered. The scientists say the AMOC cannot be allowed to fail. They have no idea of the level of carbon dioxide emissions, that would trigger its collapse. Hoping to reach carbon zero in 2050, might well be too little, too late? The scientists involved in the study, clearly feel that a safer strategy would be to reduce 'greenhouse gas' emissions now.
