Extreme Climate Change Could Elicit Cataclysmic Collapse of Atlantic Ocean Current, Scientists Warn

The climate change is highly affecting the ecosystem of the world, and we all know that. But a recently published study has warned about the extreme harshness of abnormal climatic patterns as it can cause the cessation of the ‘current’ that keeps North Atlantic warm. In the research, the scientists warned that Climate change is currently going on in a so extreme state that might set off the catastrophic crumple of a crucial Atlantic Ocean Current that maintains the healthy temperature in North Atlantic. Moreover, it also cautions that the climate change is also likely to throw some regions of the Northern Hemisphere into a freezing state.

The Atlantic Meridional Overturning Circulation (AMOC) current is responsible for the warm atmosphere in the frosty North Atlantic. It streams temperate water from the tropics to the North Atlantic, which in other ways helps to regulate the climatic and weather patterns across the globe. As it discharges the warmness into the atmosphere, the chilled water goes downwards and streams back to the tropics for replicating the procedure.

But, now the scientists, after witnessing the extreme climatic conditions have expressed their concerns that soon, the AMOC will be unable to convey its warmness to the environment which in another manner will make ocean’s great circulatory engine to be idle and eventually blackout. Scientist Wei Liu from the Yale University has estimated that the Atlantic Meridional Overturning Circulation is likely to split up within next three decades. The graphic published in the research report also exemplifies the envisaged responses on shell hotness and rainfall.

In the study, published in the journal Science Advances, the scientists also caution that the changing patterns of climate may soon bring freezing winters for North Atlantic’s countries and can cause the spreading out of the ocean ice in the Greenland, Iceland, and Norwegian seas and also trigger extreme rainfalls across the globe. However, the lead researcher has confirmed that, though most of the climate projections, conducted till date have been supposing a weakening state of AMOC in coming years, but it can still carry on because the global temperature is moving stealthily and steadily upward.

Commenting on this matter, Tom Delworth, a senior scientist at the National Oceanic and Atmospheric Administration said, “As AMOC is a key player in the atmospheric system of Europe and North America, as well as the entire world, its collapsing possibility is a big deal.”
