Recent observations have highlighted unusual patterns in polar regions, with Antarctic sea ice behaving strangely and the Arctic experiencing a below-average winter peak. Experts, including Ayesha Tandon, Mark Serreze, and Zachary Labe, have commented on these anomalies. Data from the Copernicus ECMWF ERA5 reanalysis revealed temperature anomalies across the Arctic over the last 12 months, including anomalous warmth in northern Siberia extending toward the North Pole, with temperatures over >8°C above the 1981-2010 average during February 2024. Additionally, the Antarctic Circumpolar Current is reportedly speeding up, which could accelerate the wasting of Antarctica's ice, raise sea levels, and potentially impact the ocean's capacity to absorb carbon from the atmosphere, according to researchers at the Earth Institute.
The North and South Poles are united in facing profound upheaval because of global warming. But compared with the changes affecting the Arctic, those threatening the Antarctic are greatly underappreciated https://t.co/lTgqacA7UG 👇
Transition time of year... central #Arctic (e.g. >80°N) continues to be very cold for weeks after the annual sea-ice extent max. However, this max is reached in March due to melting sea ice in the marginal seas - note how far south they extend! Graphic at https://t.co/Gq4vXKSmyg. https://t.co/cjEWmZHywV
