Antarctica’s heatwaves are a warning to humanity – and we have only a narrow window to save the planetClimate scientists

Antarctica’s sea ice levels are plummeting as extreme weather events happen faster than scientists predicted
Antarctica is currently experiencing dramatic changes at unprecedented rates, marked by repeated extreme events. These include circum-Antarctic summer heatwaves and an autumn heatwave last year, with temperatures soaring up to 40C above the average. Moreover, both last summer and this winter, sea ice extent has reached record lows. These changes have happened even faster than scientists predicted.
These changes coincide with a broader global pattern of extreme air and sea surface temperatures, wildfires, floods, disease and other events deeply impacting ecosystems and society. Scientists have warned society about global climate change and its impacts since the Intergovernmental Panel on Climate Change’s first report in the early 1990s. The Antarctic community has done so repeatedly too. These warnings are now being realised.
Antarctica is a crucial component of the Earth system and a sentinel for growing change. As Antarctic scientists, we see the evidence of mounting change, including changes in food webs, rapid change in populations, breeding failure and local ecosystem collapse, with projections of rapid transformation of a region that makes our planet liveable and contributes in extraordinary ways to global biodiversity.
This is a critical moment, impacting our well-being, future generations and ecosystems globally. Confronted by this evidence, we urgently call on nations to intensify and exceed their current commitments to greenhouse gas emissions reductions. An immediate increase in ambition is required to reach net zero and to go beyond it. Pledges are not enough.

Oh! Well! If it’s happening, “faster than scientists predicted,” then it’s not our fault for not acting before now!Fri 4 Aug 2023 02.43 EDT
