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 |     Salman Khan and Hollywood icon Johnny Depp captivated audiences at the Red Sea International Film Festival, as viral photographs of their warm encounters and polite interactions quickly spread across social media, generating excitement among fans worldwide. The presence of these two veteran actors together sparked a wave of admiration and discussion, with many celebrating their meeting as a big cross-cultural event.           At the festival's closing ceremony, both stars presented themselves in their finest attire. Salman Khan chose a subtle and elegant style, wearing an ink-blue suit with a coordinating shirt, which beautifully enhanced his unique charm. Johnny Depp, known for his diverse yet classic fashion sense, donned a grey suit with a dark shirt and a scarf draped around his neck. The two were seen engaging in genuine conversations, sharing smiles, and posing for photographs, much to the delight of those in attendance.                                                                 View this post on Instagram          A post shared by Red Sea Film Foundation (@redseafilm)               Fans soon took to social media, expressing their surprise and pleasure at seeing two global icons in the same photo. A fan said, “When Bollywood meets Hollywood at the Red Sea Film Festival: Salman Khan and Johnny Depp serving looks and legends.” Another said, “Just look at the aura, man.” A third amused fan remarked, “Johnny Depp and Salman Khan, what kind of multiverse is this?!”            Salman also ran into Hollywood actors Idris Elba and Edgar Ramirez at the festival, and pictures of their meeting quickly went viral. At the event, Salman Khan presented the Red Sea Honoree Award to actor-director Idris Elba.           The description on the festival’s official social media account said, “Congratulations to actor and filmmaker Idris Elba for being honoured at RedSeaIFF25 with the Red Sea Honoree Award, presented by Salman Khan.”            Salman's most recent appearance was in Sikandar, which did not achieve the expected success. He also made a brief cameo in Aryan Khan's directorial debut web series, The Ba***ds of Bollywood.            On the work front, Salman Khan is currently preparing for his upcoming war drama, Battle of Galwan, directed by Apoorva Lakhia. This film draws inspiration from a chapter in the book India's Most Fearless 3, delving into the Indo-Chinese conflict in the Galwan Valley. A character poster featuring Salman has already been released, and fans are eagerly awaiting the first official look at this much-anticipated film.     Also Read: Salman Khan Says He Hasn’t Gone Out for Dinner in 25 Years at The Red Sea Film Festival。
