A new record high temperature for the Antarctic continent of +18.3C has been confirmed by the World Meteorological Organization (WMO). It occurred on 6 February last year at Argentina’s Esperanza research station. The mark was widely reported at the time but has now been validated by a WMO committee set up to check extreme weather data from around the globe. The same group rejected an even higher Antarctic claim for 2020 of +20.75C, “recorded” on Seymour Island.

Guest post: Deciphering the rise and fall of Antarctic sea ice extent. The sharp decline in Arctic sea ice over recent decades has become one of the most enduring images of the Earth’s warming climate. Yet, at the same time, the sea ice changes at the Earth’s south pole have been much less clear-cut. Antarctic sea ice extent increased gradually over much of the satellite record (1979 to present), reaching successive record highs in 2012-14. Yet, 2016 saw the beginning of the most pronounced fall in sea ice cover ever observed. Over the three years that followed, the precipitous drop in Antarctic sea ice was equivalent to 30 years of sea ice loss in the Arctic. These fluctuations led the Intergovernmental Panel on Climate Change (IPCC) to conclude in its 2019 special report on the ocean and cryosphere that Antarctic sea ice extent “overall has had no statistically significant trend” due to “contrasting regional signals and large interannual variability”.

We are running out of superlatives to describe what climate change is doing to the weather. Temperature records have been broken, smashed and then obliterated. Droughts have been prolonged, extreme and then brutal. Storms have gone from damaging to unprecedented to apocalyptic. Eventually we are left with the language of destruction and death, as only this can adequately communicate the consequences of our actions. Hundreds of lives have been lost under the deadly heat dome that has settled over the Pacific Northwest. This lethal heat is the result of a region of high pressure. That in turn is the result of sea temperatures in the Western Pacific being much higher than in the Eastern Pacific. This puts into motion a vast conveyor belt of hot air that snakes its way over the Pacific. When it meets North America, it becomes trapped by the high-altitude winds of the jet stream. The end result is weather beyond our endurance.

Land temperature in the Arctic Circle has reached peaks of 48C during a “persistent heatwave” in Siberia. The European Union’s Copernicus Atmosphere Monitoring Service said land surface temperature “widely exceeded” 35C across the Russian region on the first day of summer. Siberia has been hit by wildfires and hotter than usual temperatures in recent years. Scientists found the heatwave experienced by the far northeastern region last year would have “effectively impossible” without the man-made climate crisis.

A refuge for polar bears and walruses known as the Arctic’s “last ice area” experienced record melting last summer, indicating that it may disappear much sooner than expected because of global warming. The Wandel Sea, a region north of Greenland, is normally covered by compact, thick, multi-year ice that is expected to persist longer than anywhere else in the Arctic in the face of climate change. However, it incurred a dramatic loss in sea ice last year, mainly as a result of strong summer winds blowing ice away, according to a study by a team at the University of Washington in Seattle.
