There is a disturbing trend at the bottom of the ocean, and science is actively learning more.
The process of climate change making the Earth hotter is something we have known about for a long time. But how effective was the effect of this process, only scientists could answer.
And in a recent study of the deepest seas on the ocean floor, scientists discovered a heartbreaking truth: Global warming has already happened!
In fact, much of the ocean’s surface has absorbed most of the heat produced by humans with the Earth. This makes the surface of the sea warmer. However, the circulation of water slowly reduces this heat. According to the United States’ National Oceanic and Atmospheric Administration (NOAA), they discovered warm water currents in the deeper parts of the South Atlantic.
Specifically, when analyzing 10-year temperature data (2009 to 2019) in the Argentinian Basin (in the Atlantic), the scientists found that 4 regions warmed by about 0.02 to 0.04 degrees C, depending on the depth. One of them is located at a depth of 4757 m and the change in temperature of the surrounding water is of great concern.
“For a long time, everyone thought the deepest waters are always calm. No ocean currents, no spinning. Everything is the same,” said NOAA expert Chris Meinen.
“But every time we watched it, we found things more complicated than imagined.”
This complication is in part due to the location. These are very deep seas – literally, that is, extremely difficult to crawl in. However, some calculations made by recent climate models show that deep sea water tends to heat up. In which, the southern part of the Atlantic Ocean is more influenced than the north.
Scientists obtained data from four anchors under the Argentine Basin. At a depth of 1360 to 3535 m, the temperature changes more than expected. When it goes further, the changes are less, but the changes in trend are similar to what happens on the surface of the sea.
The impact of this phenomenon on local ecology and weather conditions is not yet clear. However, given the importance of airworthiness to the global climate system, this is probably not good news.
