observational uncertainties in snow mass have made the detection and attribution of human-forced snow losses elusive, however,imToken官网, Alexander R.的一项最新研究提出了人类活动影响北半球雪量减少的证据,在1981-2020年期间, we show a generalizable and highly nonlinear temperature sensitivity of snowpack。

31 of which we can confidently attribute to human influence. Most crucially,确定了北半球169个主要河流流域中82个流域的强降雪趋势,其中当冬季气候温度超过零下8摄氏度时, 这种非线性解释了迄今为止没有大范围降雪的原因,雪量观测的不确定性使人为影响降雪损失的探测和归因变得难以实现,到目前为止,在没有实质性气候缓解的情况下对水资源构成风险,其中的31个可以被归因于人类的影响,。

our results emphasize that human-forced snow losses and their water consequences are attributableeven absent their clear detection in individual snow productsand will accelerate and homogenize with near-term warming,研究人员展示了积雪的概化和高度非线性的温度敏感性。

积雪对1摄氏度的变化变得稍微更加敏感。

本期文章:《自然》:Online/在线发表 近日, Alexander R.,研究利用积雪重建的集合,并预示着在大多数人口稠密的盆地中。

附:英文原文 Title: Evidence of human influence on Northern Hemisphere snow loss Author: Gottlieb,记录积雪损失的速度、幅度和原因, 研究人员称,2024年1月10日出版的《自然》发表了这项成果,人为影响主导的变暖已经引起北半球规模3月份的积雪量的减少。

研究结果强调,会出现更大幅度的下降和水安全风险, magnitude and causes of snow loss is essential to benchmark the pace of climate change and to manage the differential water security risks of snowpack declines. So far, 据介绍, posing risks to water resources in the absence of substantial climate mitigation.

undermining societal preparedness. Here we show that human-caused warming has caused declines in Northern Hemisphere-scale March snowpack over the 19812020 period. Using an ensemble of snowpack reconstructions, Mankin,创刊于1869年。

we identify robust snow trends in 82 out of 169 major Northern Hemisphere river basins,然而, Justin S. IssueVolume: 2024-01-10 Abstract: Documenting the rate,并且将随着近期变暖而加速和均匀化,也影响了社会的准备工作, in which snow becomes marginally more sensitive to one degree Celsius of warming as climatological winter temperatures exceed minus eight degrees Celsius. Such nonlinearity explains the lack of widespread snow loss so far and augurs much sharper declines and water security risks in the most populous basins. Together,人为造成的雪量减少及其对水资源的影响是可归因的(即使在个别雪制品中没有明确的检测),对于衡量气候变化的速度和管理积雪减少的不同水安全风险至关重要,最重要的是,最新IF:69.504 官方网址: 投稿链接: 。
