New Study Reveals Flaws in Climate Models: Future Permafrost Loss in Asia’s ‘Frozen Giants’ Less Severe Than Predicted

New Study Reveals Flaws in Climate Models: Future Permafrost Loss in Asia’s ‘Frozen Giants’ Less Severe Than Predicted

Breaking News, Climate Actions, Environment
In a groundbreaking study, scientists from the Institute of Atmospheric Physics at the Chinese Academy of Sciences have exposed significant overestimations in climate models predicting permafrost loss in High Mountain Asia (HMA). Known for its vast frozen carbon reserves, HMA has been at the center of global climate concerns. However, the latest research reveals that by fine-tuning model sensitivity to align with realistic warming projections, the feared permafrost degradation may be significantly less severe than previously believed. The study, published in Geophysical Research Letters, finds that previous climate models with overly high equilibrium climate sensitivity (ECS) levels have led to exaggerated warming predictions, distorting forecasts for permafrost loss across HMA. With ne...

Scientists Unveil New Findings on Thunderstorm Ground Enhancements

Breaking News, Climate Actions, Environment
Scientists at the Alikhanyan National Science Laboratory on Mount Aragats have uncovered new insights into a mysterious atmospheric phenomenon known as Thunderstorm Ground Enhancements (TGEs). Led by physicist Ashot Chilingarian, the research offers a deeper understanding of how thunderstorms affect the Earth's atmosphere and could shed light on larger cosmic processes. TGEs are intense bursts of electromagnetic activity that occur during thunderstorms, where electrons are accelerated to high speeds by strong electric fields. These accelerated electrons produce gamma rays, a type of high-energy radiation, as they collide with atomic nuclei in the atmosphere. The phenomenon has been largely overlooked in previous thunderstorm research, but scientists now believe it plays a significant ro...
Rising Tornado Activity in Pennsylvania Sparks Concerns Over Climate Change and Future Risks

Rising Tornado Activity in Pennsylvania Sparks Concerns Over Climate Change and Future Risks

Breaking News, Disasters
On a quiet afternoon in September 2021, Chris Erdner and her husband were at home in Montgomery County, Pennsylvania, when an urgent warning flashed on their television screen. The remnants of Hurricane Ida had sparked a tornado in their area, and residents were being told to seek shelter immediately. The couple rushed to their basement, and moments later, they heard the unmistakable roar of a tornado passing directly over their home. "I don't know if you've ever heard it," Erdner said, describing the noise. "It sounds like a freight train." Though the storm lasted only a few minutes, the destruction it left behind was extensive. Large trees were uprooted, power lines were downed, and some of her neighbors’ homes were severely damaged. One house lost its entire second floor. When the st...
