Description: On 20th March 2022, Temperatures at the Concordia Research Station, a French-Italian research station on the Antarctic Plateau, reached 10°F or -12°C. This was about 40°C warmer than the average temperature. At the same time, weather stations near the north pole also showed signs of melting, with some temperatures 30°C above normal. The sudden heatwaves at both of Earth’s poles are causing alarm among climate scientists, who have warned of these “unprecedented” events as a signal of faster climate breakdown. Normally, at this time of year, the Antarctic should be rapidly cooling after its summer, and the Arctic only slowly emerging from its winter, as days lengthen. According to the warnings issued by scientists on IPCC’s comprehensive review of climate science, the rapid rise in temperatures at the poles is a warning of disruption in Earth’s climate systems. Looking first at the global temperature anomalies for March so far, we can see a large area of warmer than normal temperatures over the western Polar regions. As the warmer air moves into the polar regions, it usually means that colder air moves out. Hence, colder than normal temperatures can be found in most of Canada, most of the west-central United States, and over parts of Europe and Siberia. Strong pressure systems in the sub-polar regions are also creating a “wind tunnel” from the North Atlantic into the Polar Circle. The Heatwaves at the poles are a strong signal of the damage humanity is wreaking on the climate, and the melting could also accelerate further climate breakdown. Secondly, as polar sea ice melts, particularly in the Arctic, it reveals the dark sea that absorbs more heat than reflective ice, warming the planet further. The latest unprecedented weather patterns are also following a series of alarming heatwaves in 2021 which in turn resulted in a series of forest fires around the globe including North America and Turkey.
