<\/a> Climate change may cause a natural circulation system that regulates the Atlantic <\/strong>ocean\u2019s temperature to collapse sometime between 2025 and 2095<\/strong>, according to a study<\/a> published in Nature Communications last week. The collapse of this ocean circulation system \u2014 called the Atlantic meridional overturning circulation (Amoc) \u2014 could lead to northern regions such as Scandinavia having a climate similar to that of Alaska, co-author of the study Susanne Ditlevsen told The National<\/a>. At the same time, tropical areas will face even hotter temperatures on top of the already damaging impacts on global warming, Ditlevsen said, adding that there will also be a greater risk of storms, more extreme weather, and altered precipitation patterns. The study was carried out based on a business-as-usual scenario in which greenhouse gas emissions continue to increase, a scenario in which the UN\u2019s Intergovernmental Panel on Climate Change (IPCC) considers one of the worst possible tracks.<\/p>\n

It was not predicted to happen this century:<\/strong> A 2019 report by the IPCC predicted that the Amoc would weaken over this century, but that its full collapse before 2100 was unlikely, CNN<\/a> reported last week. While the researchers behind the latest study think the collapse will occur between 2025 and 2095, they say it will most likely take place around mid-century.<\/p>\n
