An international group of scientists found that the South pole of the Earth over the last 30 years warmed three times faster than the rest of the planet. About the temperature record, recorded in Antarctica, according to 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 least affected by climate change due to global warming. However, the data of weather stations, collected over 60 years, and the results of computer simulation showed that it is not.
The reason for the warming was the increase of water temperature in the Western Pacific ocean, which for decades reduced atmospheric pressure over the Weddell sea in the Atlantic part of the southern ocean, off the coast of West Antarctica. This, in turn, increased the flow of warm air directly over the South pole — since 1989, it heated up more than 1.83 degrees Celsius.
Although it was known that the temperature in West Antarctica and on the Antarctic Peninsula during the twentieth century increased at the South pole was colder and scientists thought that this part of the land is immune to global warming. However, he is currently warming at a rate of about 0.6 degrees Celsius during the decade, compared with 0.2 degrees Celsius for the rest of the world. In part, this may be due to a natural cycle called merdekan Pacific oscillation, lasting about 15-30 years. However, the rate of warming exceed the contribution of this cycle, and scientists believe that the cause is human activity.
