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.

。8月26日，《每日经济新闻》记者向特斯拉中国方面求证，一位内部人士回应称：“不实消息。”　　公开信息显示，特斯拉在中国的FSD数据合规及本土化准备仍在推进。特斯拉上海数据中心已实现境内数据全留存，位于上海临港的AI（人工智能）训练中心于2026年2月投入运营，并与百度地图合作使用合规高精地图。此前，特斯拉相关车型已通过四项汽车数据安全标准认证，为FSD进一步推进中国市场适配和数据合规奠定基础。　　值得注意的是，此次“数据中心撤离”传闻或与另一则消息叠加有关。　　近日，有网友发现，特斯拉北美官网更新了FSD监督版的全球可订阅地区名单。最新名单显示，目前全球仅有12个地区开放FSD监督版订阅，分别为美国、加拿大、墨西哥、波多黎各、澳大利亚、新西兰、韩国、荷兰、立陶宛、爱沙尼亚、丹麦和比利时，名单中并未出现中国。　　不过，记者进一步核实发现，相关说法存在一定误读。上述名单列出的是目前可以开通FSD监督版“订阅”（Subscription）的地区，并不等同于FSD监督版可以实际使用的全部地区。

三 | 由于目前中国市场尚未开通FSD监督版订阅服务，因此中国并未出现在这份名单中。图片来源：特斯拉官网　　与此同时，记者在特斯拉美国官网查询发现，在FSD监督版的可使用地区列表中，中国（China）仍然位列其中。　　事实上，特斯拉此前并未释放退出中国市场FSD适配工作的信号。今年2月，特斯拉全球副总裁陶琳曾表示，特斯拉会积极参与中国自动辅助驾驶领域的发展。

四 | 她同时透露，虽然特斯拉尚未正式向中国用户推送“满血版FSD”，但公司一直在针对中国市场进行适配，在中国设有训练中心，并已提前部署适应中国市场的训练能力。（文章来源：每日经济新闻）。
