The climate is a complex machine sensitive to variations, the health of each cog determining that of those it turns. Thus, temperature variations in the Pacific Ocean can have a drastic and unexpected effect on climatic conditions in Antarctica. This is the worrying constant that has recently been made by an international team of researchers. By analyzing 60 years of meteorological data, and thanks to the implementation of computer models, these have brought down – with horror – a belief shared for decades by scientists: that Antarctica was cooling while the rest of the world was sitting on a hot plate.
The South Pole is heating up
Long hidden by natural climatic phenomena, the increase in SAT at the South Pole has just been revealed in all its magnitude, displaying the alarming figure of 0.6 ° C additional per decade over the past 30 years! “data-reactid = “14”> If an increase in the temperature of the surface air (SAT) is undeniable observable at the world level, and this, since the XIXe century, not all regions are created equal. Researchers thus estimate that, since the 1970s, the planet has been warming from 0.15 to 0.2 ° C per decade on average. But, in Antarctica, it is a completely different picture that is being painted. Long hidden by natural climatic phenomena, the increase in SAT at the South Pole has just been revealed in all its magnitude, displaying the alarming figure of 0.6 ° C additional per decade over the last 30 years!
Kyle R.Clem, lead author of the study published in the journal Nature Climate. Recorded on site since 1957, pole temperatures have so far appeared to be stable or declining according to the data. Winds from the west formed a protective barrier around the continent, preventing warm air from entering it. Nevertheless, towards the end of the XXe century, the enemy was preparing to storm the ice fortress, not by air but by water. “data-reactid =” 15 “>” The South Pole is heating up at an incredible rate, and this change is mainly fueled by the tropics “, Explain Kyle R.Clem, lead author of the study published in the journal Nature Climate.
