Can weather have long-term effects? Yes. "A heat wave in Greenland and a storm in Antarctica. These kinds of individual weather “events” are increasingly being supercharged by a warming climate. But despite being short-term events they can also have a much longer-term effect on the world’s largest ice sheets, and may even lead to tipping points being crossed in the polar regions."

Antarctica is experiencing an unusually long heatwave this winter, making it the second warmest July since records began in 1979. The average temperature in July was 3.1 degrees Celsius above normal, showcasing a significant warming trend. While temperature anomalies are not rare in Antarctica, the extended duration of this heatwave is exceptional. Daily temperatures ranged from -34.68°C to -28.12°C, reflecting unusual warmth across the continent. This prolonged warmth raises concerns about increased ice loss and potential impacts on global sea levels. Recent studies suggest that warm ocean water is accelerating ice melting, posing risks to coastal communities worldwide. The situation highlights the urgent need to tackle climate change and mitigate its effects on polar regions. Addressing these challenges is crucial for protecting vulnerable ecosystems and populations. . . . #ClimateChange #Antarctica #GlobalWarming #IceMelting #SeaLevelRise #EnvironmentalImpact #tribunetrends

It is not known for its climate alarmism. So, it is telling that The Economist has just published a lengthy piece and a leader article highlighting the very troubling developments in Antarctica. “The models, it turns out, were wrong. A build-up of jaw-dropping events and extremes in recent years has shown that Antarctica is undergoing massive changes on land, sea and in the atmosphere above. As a result, a new portrait of the continent is emerging which has, so far, received little attention. Polar scientists are warning of a regime shift.” #climate #environment #permacrisis #metacrisis #climatemajority #adaptation https://lnkd.in/et2E5g2b from The Economist

Adam, nice post - Ref: International Geophysical Year, 1957-58, leading through the unique Antarctic Treaty, 1961, to the Antarctic Environmental Protection Protocol, 1992, due for renewal 2042-48. So 32 years have passed since the UN Rio Earth Summit spawned the UNFCCC UN and ,all in the same year, the Antarctic Env Protocol. All the signals there, likely lots of coal/ oil under Antarctica…….we must learn even if too late and protect the Antarctic Env Protocol when up for renewal in 18 years…..

Breaching 1.5°C Threshold Across One Year⁠ ⁠ Humans have caused major climate changes to happen and extreme weather is now a part of our lives.⁠ ⁠ For the first time, average global air temperature across the entire year was 1.53°C hotter than before industrialisation, the world’s sea surface was at its highest ever recorded average temperature and the extent of sea ice in the Earth’s polar regions was the lowest on record, according to the EU’s Copernicus Climate Change Service (C3S).⁠ ⁠ January 2023 to February 2024 was a year filled with more extreme droughts, searing heatwaves, intense rainfall, rising sea-levels, loss of wildlife and deadly disasters worldwide.⁠ ⁠

Ground temperatures across vast stretches of Antarctica's ice sheets have surged by an alarming 10°C above normal in July. It has set a record for extreme heat in one of the coldest places on Earth. While Antarctica is cloaked in winter darkness in July, temperatures have shockingly risen to 28°C above what's considered normal, on some days. This isn't just an isolated event—it's a stark indicator of a global trend. We've now endured 12 consecutive months of unprecedented warmth, with temperatures consistently surpassing the critical 1.5°C increase over preindustrial levels, a threshold once considered crucial for mitigating severe climate impacts. Michael Dukes, Director of Forecasting at MetDesk, emphasizes that while the daily highs are startling, the overall monthly average rise is far more concerning. Climate models have long warned that the polar regions would bear the brunt of climate change, and this is a grim testament to that reality. As we grapple with these extreme changes, it's crucial to recognize the severity of the situation. The impacts on our planet are more profound than ever, and urgent action is needed to address this escalating crisis. 🌡️🚨 Image Courtesy: Metdesk #ClimateChange #Antarctica #GlobalWarming #UrgentAction #ClimateCrisis
