Melting Antarctic ice will slow down a major global deep ocean current by 40% by 2050
Daily MailMelting ice around Antarctica will spark a rapid slowdown of a major global deep ocean current by 2050 that could have devastating impacts on ocean health and the marine food web. Warning: Melting ice around Antarctica will spark a slowdown of a major global deep ocean current by 2050 that could have devastating impacts on ocean health and marine life The scientists warn that if greenhouse gas emissions continue at today's levels, the current in the deepest parts of the ocean could slow down by 40 per cent in just 30 years. This graphic shows how the ocean near Antarctica has warmed and will continue to do so until 2050 and beyond unless more is done to tackle global warming emissions across the world The world has very few places that produce water that is cold enough and dense enough to sink to the deepest parts of the ocean, but Antarctica has four such locations. Unfortunately, however, the melting ice is stopping water from becoming dense enough to reach these levels 'Direct measurements confirm that warming of the deep ocean is indeed already underway,' Dr Rintoul added.
