An international team of scientists found that the South Pole of the Earth over the past 30 years warmed up three times faster than the rest of the planet.
The temperature record recorded in Antarctica is reported in an article published in the journal Nature Climate Change. It is known that the temperature of Antarctica varies widely depending on the time of year and region, so for many years it was believed that the continent is least affected by climate change due to for global warming.
However, the data of weather stations collected over 60 years and the results of computer modeling showed that this is not so. The cause of the warming was the increase in water temperature in the western part of the Pacific Ocean, which for decades reduced atmospheric pressure over the Weddell Sea in the Atlantic part of the South Ocean, off the coast West Antarctica.
This, in turn, increased the flow of warm air directly above the South Pole – since 1989, it has heated by more than 1.83 degrees Celsius. Although it was known that the temperature in West Antarctica and the Antarctic Peninsula increased in the 20th century, at the South Pole it was getting colder, and scientists thought that this part of the land was immune to global warming. However, it is currently warming up at a speed of about 0.6 degrees Celsius for a decade, compared with 0.2 degrees Celsius for the rest of the planet. In part, this may be due to the natural cycle, called the inter-decade Pacific oscillation, lasting about 15-30 years.
However, the rate of warming exceeds the contribution of this cycle, and scientists believe that the cause is still human activity.
