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

一 |     本地共享充电宝服务需求持续上扬。有业者表示使用量同比增加三倍，平均每月租借1万5000个充电宝。共享脚踏车业者也看准商机，开始提供共享充电宝服务，要在市场上分得一杯羹。

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.

。本地最大共享脚踏车业者Anywheel去年10月进军共享充电宝市场，服务率先在这家酒店试点推出。站点数量之后每月增加，目前集中在酒店和餐饮场所。

二 | 共享脚踏车公司创办人杨源家说：“包括游客包括本地的这些用户，我们得到的反馈就是他们有时候出去，要那个导航那个谷歌地图这些的时候，会没有电或者出去一整天。然后我们同时也是一个共享平台，我们就继续（增加）这个共享业务就是充电宝。”新加坡乌节门今旅酒店营运总监陈玉娟说：“我们有客人到我们的服务台问我们有没有这个服务给他们，但是我们那时候没有。

三 | 我们酒店希望就给客人更好的一个服务。”一家业者目前在全岛设1000个站点，每个站点最多有48个充电宝，最少的有六个。大型购物中心和卡拉OK场所的租借率最高。新加坡加电科技董事周利忠说：“使用率比较高的场所的话，可能一台机器上面20、30个充电宝都会被全部租用掉。我们有自己的后台系统可以去查看，然后我们根据客户的使用情况会及时去补充充电宝。

四 | ”业者说星期五，周末和公定假日的租借率最高。

五 | 公司计划明年将站点扩大到2000个。嗨翻市场部负责人王顼玲说：“为顾客带来很大很大的方便。之前就有一点麻烦，就是说我们需要提供一些我们可能自己的那个电源那些，还是我们自己门店的一些员工自己的设备。

六 | ”一家在全岛有约100个站点的业者指出，近几个月的共享充电宝需求，比之前高约八成，7月达6000多个。业者计划今年内将站点增加到300个。
