30 years of weather data reveals how Antarctica is warming three times faster than the rest of the Earth

The South Pole has one of the most inhospitable climates on Earth and is one of the most distant places of human activity. Due to factors like these, it was thought to be not as affected by global warming as other parts of the world. However, new research shows the opposite is true: Antarctica sees average temperatures rise up to three times faster than the rest of the world.


The study published in Nature shows how the temperatures in this region of the planet have increased in recent decades. More specifically, they point out that they have increased on average at 0.6 ° C per decade, while in the rest of the world the average is around 0.2 ° C every ten years.

Average temperatures at the South Pole range from -60 ° C in winter (southern winter) to -20 ° C in summer (although quite surprising exceptions such as the 20 degrees Celsius recorded this year sometimes occur). The huge mass of Antarctica has changed these average temperatures over the years. But it’s not the same, While the western part has warmed, the eastern part has maintained and even reduced temperatures. This is due to the shape of Antarctica and its transantarctic mountains, which act as a wall to separate the continent in two.


1.8 ° C more in three decades

The Amundsen-Scott scientific base has the most southerly observatory on Earth and has been collecting data on the meteorology of the place since 1957. As observed in the data collected, from 1989 to 2018 on average the figures increased by 1.8 ° C. Researchers suspect that the flow of warm air from outside and towards the interior plateau of Antarctica was the main cause.

Another relationship they discovered is between the Temperatures of the western tropical Pacific and the South Pole. They noted that many of the warmest years on the Antarctic continent occurred when the Pacific also had strangely high temperatures.

Although the shape of the continent and the conditions of the Pacific have influenced, that does not mean that humans have nothing to do with it, according to the researchers. They analyzed a total of 200 simulations of climate models in which they included greenhouse gases from 1989 to 2018. Result? They estimate that of these additional 1.8 ° C average temperature, 1 ° C is a consequence of human activity.
