Scientists Warn Atlantic Current Changes Could Reshape UK Weather

New research and decades of ocean data suggest the Atlantic Meridional Overturning Circulation may be weakening, with potential for colder winters and more volatile weather in Britain.
- The UK government has said the AMOC, as a key component of Earth's climate system, contributes to the UK's long-term climate risks.
- A study led by University College London found the Atlantic circulation was "abruptly altered" during the Younger Dryas cooling period 13,000 years ago.
- Professor Stefan Rahmstorf of the Potsdam Institute said he has changed his view and now believes the risk of an AMOC shutdown has increased.
- The IPCC's 2021 assessment concluded the AMOC is very likely to weaken this century, but an abrupt collapse before 2100 was not expected.
