ANOTHER HIDDEN PROBLEM FROM CLIMATE CHANGE.

An Atlantic Ocean current that brings warmth north from the tropics could collapse much sooner than scientists have previously thought, a new study suggests. Known as the Atlantic Meridional Overturning Circulation (AMOC), this current prevents the UK and other countries in north-west Europe from having the same icy winters often experienced at the same latitudes in Canada. As the warm water flows north it cools and evaporates, becoming saltier and denser, which makes it sink and head southwards before it is pulled to the surface and warmed again, repeating the cycle. Greenhouse gases produced by people since the industrial revolution have been warming the ocean and melting ice in the polar regions, changing the temperature and the amount of freshwater in the Atlantic. Many climate models show the Amoc is likely to weaken in future because of global warming and the Intergovernmental Panel On Climate Change has suggested it could lead to a collapse. This would have a disastrous effect for everyone on Earth, scientists have said, as within a few decades it would cause temperatures to plunge across the northern hemisphere and shift rainfall patterns southward, starving places like the UK of the freshwater needed for drinking and agriculture. Another effect would be to increase the temperature of the tropics even faster than is happening currently as heat that would normally be brought north would remain there. The effect on renewables in the northern hemisphere could be seriously affected and whole governmental policies needing speedy review. No point in pushing EVs if the solar and wind power is diminished. Immediate legislation is required to stop fossil fuel power generation world wide but that will never happen.
