The Arctic Ocean began warming decades earlier than previously thought, new research shows

The study, published Wednesday in the journal Science Advances, found that the expansion of warm Atlantic Ocean water flowing into the Arctic, a phenomenon known as"Atlantification," has caused Arctic water temperature in the region studied to increase by around 2 degrees Celsius since 1900.

The researchers used marine sediments in the Fram Straight, where the Atlantic meets the Arctic east of Greenland, to reconstruct 800 years of data that paint a longer historical picture of how Atlantic water has flowed into the Arctic. The marine sediments are"natural archives," the researchers wrote, which record data on past climate conditions.

Muschitiello said it's not clear how much of a role, if any, human-caused climate change played in the early Arctic warming, and more research is needed. A recent study found that the AMOC, often described as a"conveyor belt" that transports warm water from the tropics and redistributes it northward, is now showing signs of further instability due to human-caused climate change. Scientists have warned that a collapse of the circulation could lead to an abrupt shift in weather patterns across the globe — colder winters in Europe, changes to monsoons and potentially permanent drought in West Africa.

"Loss of sea ice and ocean currents has shifted the buffer region between the Atlantic and Arctic Ocean to something closer to an arm of the central Atlantic," Overland, who was not involved with the study, told CNN."Important fisheries and marine mammals are vulnerable to ecosystem reorganization from such Atlantification."

expect China to be there soon.when they do, blow them to smithereens!
