How close the world is to a catastrophic collapse of giant ocean currents is unknown, making halting global warming more critical than ever, scientists saySerious disruption to the Gulf Stream ocean currents that are crucial in controlling global climate must be avoided “at all costs”, senior scientists have warned. The alert follows the revelation this week that the system is at its weakest ever recorded. The new research worries scientists because of the huge impact global warming has already had on the currents and the unpredictability of a future “tipping point”. We should avoid disrupting the Amoc at all costs. “But they differ a lot because it depends on a very subtle balance of density – that is temperature and salinity distribution in the ocean.
