Antarctic ice sheet loss temporarily slows due to remote influence of tropical warm pool: Chinese, foreign scientists_我的网站

Joint research by Chinese and international scientists have found that the rate of long-term Antarctic mass loss has slowed, driven by sea surface temperature anomalies in the remote tropical warm pool, China Central Television (CCTV) reported on Thursday, citing a statement released by the Institute of Oceanology, Chinese Academy of Sciences (CAS).
The Antarctic ice sheet is one of the major sources of uncertainty in global sea-level rise forecasts. From 2003 to 2024, the Antarctic ice sheet lost an average of approximately 140.5 billion tons each year, CCTV reported.
However, Chinese and foreign scientists have found that the Antarctic ice sheet gained roughly 695 billion tons between July 2021 and April 2023, the largest 22-month mass gain seen in nearly two decades via satellite gravimetry, the Institute of Oceanology, CAS announced on Thursday.
The scientists found out that from 2021 to 2023, sustained heavy snowfall in East Antarctica led to significant increases in snow accumulation, partially offsetting the ongoing ice loss in West Antarctica.
The scientists' research shows that this was caused by tropical ocean-driven atmospheric processes that altered moisture transport pathways and increased snowfall over Antarctica.
The research was conducted by the research team at the Institute of Oceanology at CAS, along with peers from countries including the US, Hungary and Japan. It was published in the academic journal Nature on Wednesday.
According to Wang Yunhe, first author of the research paper and an associate research fellow at the Institute of Oceanology, sea surface temperatures in the tropical western Pacific warm pool remained unusually warm from 2021 to 2023. As one of the regions with the highest sea surface temperatures and strongest heat release into the atmosphere worldwide, changes in this region can reshape atmospheric circulation.
The persistently warmer-than-normal seawater triggered large-scale atmospheric waves.
After reaching the high latitudes of the Southern Hemisphere, the waves reshaped wind patterns and moisture transport pathways. Moisture-tracking simulations show that water vapor from the mid-latitude Indian Ocean fueled heavy snowfall in East Antarctica, leading to a recovery in ice sheet mass.
Observations and climate simulations suggest that such warming events occur roughly once a decade. But these temporary pauses are not enough to reverse Antarctica's long-term ice loss. The West Antarctic ice sheet continues to shrink, while parts of East Antarctica remain increasingly vulnerable to warmer ocean waters melting ice shelves from below and speeding the flow of glaciers into the sea.
The study shows how persistent warming in the tropical warm pool can contribute to the recovery of Antarctic ice-sheet mass, highlighting the role of East Antarctic atmospheric circulation in connecting tropical climate shifts with changes in the ice sheet. The findings point to a previously overlooked climate link between the tropical warm pool and East Antarctica, offering a new perspective on how distant climate systems may shape the continent's future.

二 | 他说，之所以选择自愿裁员的方式，是为了给员工一些掌控自己未来的主动权。除统计局外，社会发展部也采取了自愿裁员的方式，结果有404人选择自愿裁员，200人获得批准。 Sowden透露，许多人要求统计局裁员，包括公共服务协会（Public Service Association）在内。统计局裁员的目标是节省7.5%的开支，这是政府部门开支节省的最高比例。其他部门的削减要求在6.5%到7.5%之间。此前报道称，统计局高水平的员工数量“不可持续”，预算超支数百万纽币。根据《官方信息法》公布的文件显示，统计局预计将减少124人。从去年大选前一天开始，统计局已经暂停了非必要职位的招聘，直至现在。此前，统计局还要求员工限制旅行、暂停招聘、减少休假、共享办公室（基督城）等。但这些还远远不够。记者已联系统计局请其置评。相关阅读：大动荡！新西兰政府猛下狠手，首都要撑不住了？！ “黑暗的一天”，两大政府机构拟裁员上千人！被裁公务员的平均遣散费是5万，政府要解雇2000多人…… 政府节支路漫漫：38个公共服务部门又增加了数千名新员工为完成节支目标，政府这一部门将裁员384人政府今年将节省开支大举减税，有多少公务员会被裁？政府开始削减经费，这个部门率先裁撤40个职位在国家党政府上台之前，知道会裁公务员，很多合同工已转为永久员工…… 如果国家党上台，这一政府部门开支可能会被削减30% 机构越来越臃肿？工党执政下，这些部门的公关人员增加了50% 注：本文为编译/原创，欢迎转发分享；但严禁复制等未经授权的非法使用。违反上述声明者，本网将追究其相关法律责任。
