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.

B |     最近，新加坡警察部队通告，一名63岁的韩国籍男子，因为从国外弄来了15亿新币非法所得后，到新加坡狂撒钱买金条。他以为这样做就能把钱洗干净，但天网恢恢疏而不漏，警方顺藤摸瓜，还是将他逮捕了！ 示意图据悉，这起案件发生在2014年至2017年间，当时，这名被捕男子Kim，不知道用了什么法子，将这接近15亿新币全部“走私”到了新加坡。据本地媒体报道，这15亿新币似乎还不是走银行网络转来新加坡的，而是通过人肉运送到新加坡的。当局对Kim的一项指控，就是他曾经多次在未进行现金申报的情况下，带超过20000新币的现金入境......图源：见水印警方通报，在2014年的某个时候，他从韩国方面一口气收了3100万新币，然后直接将这些钱买了628根金条。为了将这些金条拿到手，他还涉嫌欺骗两家物流公司，称他的货物中只有一些气动工具。

C | 为此，他还不知道做了什么欺骗了新加坡海关，让海关批准了包含金条的货物的货物清关许可证。似乎是因为这次得手让他产生了强烈信心，在之后的几年里，他屡屡这么操作并且屡屡得手。直到2017年，他陆陆续续利用这15亿新币的非法所得，一共买了28000多根金条......胆子越来越大的他，在去年2月份想故技重施。他与一个名叫Jeon姓男子再度谋欺骗新加坡海关。

D | 法庭文件中没有披露有关后者的详细信息，但这一次次他似乎被发现了。海关人员据说在他申报的货物内，发现了有15根金条。当局在接到他参与一向洗钱计划的信息后，在2023年12月将其逮捕。

E | 在掌握充分事实和证据后，警方对Kim提出了控告，他预审会议将在下个月举行。他一共面临21项指控。

F | 对于每一项洗钱罪名，Kim 都可能被判处最高 10 年监禁、最高 50 万新元的罚款，或两者并罚。对于每一项诈骗罪名，他都可能被判处最高三年的监禁、罚款，或两者并罚。对于携带超过 20,000 新元现金进入新加坡的每项未报告罪名，他可能会被处以 50,000 新元罚款、最高三年监禁，或两者并罚。

G | 看起来，他应该是要在新加坡牢底坐穿了......。
