News Briefing: 19 July 2022 Over the past decade, dozens of major high-mountain slopes around the world have partially collapsed due to accelerated ice loss, with major landslides occurring more frequently. In Alaska, unusually warm summers have triggered intense glacier melt, destabilizing sediments on rocky slopes that escalated into debris flows and tsunamis that hit […]
Science Advances, 27 July 2022 Several decades ago, an extended period with abnormally few “controlled burning” fires in the United States — resulting in greater wildfires — accelerated sea ice loss in the Arctic, unveiling a new dimension to the interconnected relationship between wildfires and sea ice. Controlled burning, the setting of planned fires to […]
On Tuesday, August 9 at 13:00 Central European time (CEST) and Wednesday, August 10 at 1PM Eastern Time (EDT), ICCI will host an informational webinar on cryosphere-related efforts within the UNFCCC processes including COP27; and provide information about the COP27 Cryosphere Pavilion, potential side events and our Early Career Scientist volunteer program. Presentations will be […]
Surface temperatures in the Arctic are more than three times higher than the global average. The communities, ecosystems, and species living in this region already experience accelerating impacts from climate change, especially those associated with extreme events. This session from the Arctic Monitoring and Assessment Program (AMAP), a working group of the Arctic Council amplifies […]
News Briefing: 20 July 2022 Temperatures in northern Greenland are running 5-7°C (10°F) warmer than normal for this time of year; and last week, three consecutive days of extremely high temperatures triggered rapid melting in this region, which normally stays below freezing even in much of the summer. Between July 15 and 17, the Greenland […]
Nature Communications, 21 July 2022 Under a high-emissions scenario, ice loss driven by the absorption of heat from the sun could increase by one third across the Greenland Ice Sheet before the end of the century. Clouds act as a shield; they help prevent shortwave and longwave radiation reaching the ground. As global temperatures rise, […]
Springer Science: Landslides, 23 July 2022 Permafrost also exists on Greenland; and rising global temperatures have accelerated its thaw, increasing the vulnerability of coastal mountain regions to unpredictable landslides and collapse. The melting of this frozen ground can open deep fractures in rocky cliffs. These expanding fractures allow rainfall and snowmelt to trickle into the […]
This session introduces “Mountains of Opportunity,” a new approach to scale up investment in mountain-specific climate priorities across the Hindu Kush Himalaya (HKH) region by ICIMOD (the International Centre for Integrated Mountain Development). This effort aims to help vulnerable communities mobilize resources in the face of snow and ice loss driven by rising global temperatures. […]
News Briefing: 14 July 2022 More than thirty glacial lakes in the Himalaya, Hindu Kush and Karakoram mountains of Pakistan are at risk of bursting and releasing several million cubic meters of water and debris. In May, a devastating glacial lake outburst flood rushed through the village of Hassanabad in Pakistan and swept away nearly […]
News Briefing: 19 July 2022 Glaciologists are monitoring a new crack on the Marmolada Glacier that partially collapsed earlier this month, intensifying concerns that such unpredictable threats could become more frequent and widespread as heatwaves intensified this week across Europe. During the beginning of July, an ice shelf broke away from the Marmolada, producing an […]
Proceedings of the National Academy of Sciences, 18 July 2022 Under a high emissions scenario, 80% of the water contained within the winter snowpack across the Rocky Mountains could disappear by the end of the century. Mountain snowpack is a natural reservoir of freshwater. As it melts throughout the spring and summer, it provides a […]
Scientific Reports，2022年7月20日即使是山区规模较小的冰湖溃决洪水，也可能演变成巨大的泥石流，将巨石席卷到大片区域，而松散的沉积物会引发额外的山体滑坡。这项研究发现，这种泥石流会加剧未来此类洪水造成的损失和破坏。融化的冰川产生大型融水湖[...]
本次会议关注能够为印度河流域（HKH）地区提供应对冰川融化威胁所需速度和规模的气候行动的高影响力解决方案；并提出了加强山区社区和经济韧性的机会。该活动由国际综合山区发展中心（ICIMOD）组织，会议期间 […]
《自然-地球科学》 2022年6月23日 喜马拉雅山脉和亚洲其他高山地区冰川加速退缩，给当地社区带来致命风险，破坏地貌稳定，并威胁要淹没众多水电项目。随着气温进一步升高，高海拔地区的冰雪资源正在以两到三倍的速度……
自然地球科学，2022 年 7 月 7 日。消耗臭氧层物质排放量的增加削弱了北极上空的臭氧层，导致北半球各地出现极端天气异常。臭氧在高层大气中起到保护屏障的作用，吸收太阳的有害辐射。随着排放量的增加，北极上空的臭氧层变薄。[...]
