The Atlantic Ocean current that drives the Gulf Stream is at its weakest for more than 1,000 years - and human-induced climate change is to blame. Known formally as the Atlantic Meridional Overturning Circulation (AMOC), it is the driving force which brings warm water from the Gulf of Mexico up to the UK and is responsible for mild winters in Western Europe. Scientists determined that in 2015 it to had slowed by at least 15 percent since 1950, but the latest work paints a picture of how it will develop long term. Experts warn that by 2100 the AMOC could weaken by as much as 45 per cent, bringing humanity dangerously close to a 'tipping point', resulting in devastating weather conditions across the world.
