Research published in the scientific journal Nature Climate Change showed that the South Pole over the past 30 years of observation heats up three times faster than other parts of the Earth. Perhaps there is no human guilt in this.
Scientists believed that warm air does not reach Antarctica as easily as the rest of the globe. But a new study showed that even the South Pole is not immune to the effects of anthropogenic climate change.
A study published in the journal Nature Climate Change reports that over the past 30 years, this region has warmed up to three times faster than any other part of our planet. Between 1989 and 2018, the largest warming trend for the last 30 years was observed here – an increase in temperature by 0.61 ° C over 10 years.
A group of scientists analyzed the data obtained using 20 meteorological stations that measure temperature in this part of the planet for several decades, and confirmed their theory. “This conclusion is especially important because it previously seemed that the South Pole is immune to warming,” the researchers noted.
Scientists emphasized the need for further research: due to the small number of temperature records and the short history of observations of meteorological stations in the interior of Antarctica, they know little about changes in this part of the planet. “In fact, we first said that the internal regions of the South Pole are subject to sharp and extreme climatic fluctuations,” the researchers added.
Along with temperature, the team studied atmospheric data. It turned out that the temperature increase is associated not only with human activities, but also with lower atmospheric pressure in the Weddel Sea, along the northern coast of the continent, which brings warmer air from the South Atlantic to the South Pole. This is probably due to an increase in temperature in the western part of the Pacific Ocean.
The authors found that the level of warming is still within the possible threshold of natural climate variability, but they emphasize that greenhouse gas emissions from humans exacerbate the situation.
