The Atlantic Meridional Overturning Circulation (AMOC), of which the Gulf Stream is a part, carries warm surface water northward and sends colder, denser water back toward the south through a deep-ocean pathway.

The planet isn’t warming evenly—it’s unraveling fastest at the top. In the Arctic, temperatures are rising four times faster than the global average, turning what was once Earth’s frozen stabilizer into a rapidly shifting engine of change.

Sea level rise, as eloquently explained by NASA’s Global Climate Change webpage, is caused by two factors.

Warming Sea Water May Be Threatening the Collapse of the Antarctic Thwaites Glacier.
