The oceans absorb more heat than ever. The researchers note that this water has increased heat at an unprecedented rate, and that this shift affects the patterns of weather and marine life, but the most important thing is that the degrees of warming were varying.
According to study It was published in the American magazine “Climate”. Scientists examined the global measurements from 2000 to 2023, and compared them to the data of the early first decade of the 21st century, and they found two extensions of the latitudes approaching 40 degrees in both half of the globe where the temperatures of the ocean rise significantly.
The research team analyzed the temperature data from the ocean water strips, which is one degree, and extends to depths of up to 6500 feet. And follow the changes during that period.
“It is not customary to discover such a distinctive style that emerges from climate data,” said Dr. Kevin Trinbert of Oakland University and the National Center for Air Cover Research in Bulder, Colorado, who led the study.
Thermal changes are not distributed evenly. Some latitudes witnessed an accelerated rise in temperatures, while other lines have maintained relative stability and the two regions that witness a rapid rise in temperatures on the line of approximately 40 degrees in both hemispheres.
Scientists note that these spots extend from the North Atlantic Ocean near the eastern coast of the United States to water near Japan, and from areas near New Zealand and Tasmana across the Atlantic Ocean in eastern Argentina.
This distribution coincided with transformations in the wind patterns that follow the jet current, a stream of strong wind that moves from west to east. The ocean currents also responded to the same transformations, as they directed heat differently than before.
In addition to medium latitudes, the researchers noticed a significant rise in temperatures between the two latitudes of 10 degrees north and 20 degrees in the south, which covered a large part of the tropical areas.
However, these changes were less consistent due to strong fluctuations in temperatures caused by a phenomenon. Nineu AndNinea.
Even with this contrast, tropical areas still absorb a large amount of heat. This energy stored in air humidity levels, which may later affect rainfall patterns in remote areas through remote communications, and climate reactions that extend for thousands of miles.
Determination of environmental systems
In general, the ocean stores more than 90% of the extra heat, and the movement of storm paths toward the poles appears to be associated with warming ranges. The researchers note that slight changes in the air cycle and wind contributed to the emergence of new heat transmission paths.
These wind patterns move sea surface and guide the path of warm currents. Hence, the ocean temperature may leak into deeper layers, which exacerbates serial reactions that affect storms and precipitation.
The rise in the ocean temperature can affect faster the amount of water vapor in the atmosphere, which in turn leads to the strengthening of conditions for heavy rains and this extra moisture extinguishes local rain, which raises concerns about floods and repeated storms.
Scientists stress the importance of natural fluctuations when studying climate patterns. While human activity contributes to high temperatures in the long run, the dynamics of regional oceans also play a role.
Although the climate change caused by human activities is the main driver of the high temperature of the ocean, researchers emphasize the role of natural diversity; Events and phenomena such as the phenomenon of nienu, and southern oscillation (annual fluctuation in the atmospheric pressure in the Indian and Pacific Oceans) can cause short -term fluctuations that exaggerate or conceal the significant long -term warming signal.
Acute temperature changes can shake the stability of marine ecosystems, which leads to changing habitats and changing the distribution of species. Warm water also disrupts the feeding areas and migration paths, which negatively affects the fisheries and coastal economies.
The new data highlights how different parts of the ocean respond to global warming in a variety of ways. Among the most strange results is that there is no significant rise in temperatures near the 20 -degree latitude in the hemisphere, and these semi -tropical areas remained relatively stable in the peripheral heat content, which highlights in light of the direction of wide warming.
The researchers note that this may be attributed to overcoming ocean currents and the air cycle of these areas. Instead of accumulating heat, the tropical areas may work as transit areas, where energy is redistributed instead of absorbing them.
