The Atlantic Ocean is Acting Weird

We've heard of the Gulf Stream, but it's just a part of the Atlantic meridional overturning circulation (AMOC). AMOC flows one way on the surface, and then a different direction in the lower depths of the ocean. This explains why the coldest regions of the continental US are at the same latitudes as the warmest parts of Europe. We will also be introduced to the "cold blob" in the ocean. But this system has shown some changes lately, thanks to glacial melting in Greenland. What does that mean for us?

The effects would be felt in Europe first, but it may affect other parts of the world as well. When will all this happen? Scientists are leery of assigning a date to the point of no return, or the point of environmental collapse. Other factors may be in play, and we can't say that today's trajectory will not change. Still, ocean currents that have been stable for a few thousand years suddenly starting to change can't be a good thing.
