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

A |     (ECNS)-- In the mountains of southwest China's Guizhou Province, industries once unlikely to be associated with a remote inland region are finding their way into global markets.    In Jiangkou County, Tongren, stands what local authorities describe as the world's largest single-site matcha refining facility. Fully automated production lines process the finely ground green tea for consumers at home and abroad.    According to local figures, one in every five cups of matcha consumed worldwide is produced in Tongren. The city's matcha products are exported to more than 50 countries and regions, with the industry generating an output value of 750 million yuan ($105 million).        For Mauro, a young visitor from Brazil, the industry raised a broader question: how can globally competitive production create opportunities for rural communities?    Tongren's matcha industry works with 73 upstream partner companies and around 13,300 hectares of tea plantations. Financial and technical support for growers, alongside links between market demand and production, helps connect local farmers with a wider supply chain.    Matcha is not the only Guizhou product reaching international markets. In Jinping County, Qiandongnan Miao and Dong Autonomous Prefecture, local industry figures suggest that one in every 10 shuttlecocks in circulation worldwide is made there. Production is supported by a supply chain extending from goose farming and feather sorting to intelligent manufacturing.        "I hadn't realised that some of the key materials used in these vehicles come from Guizhou," said Thai visitor Nim Jiratchaya, whose family owns a Chinese electric vehicle. Guizhou developed an advanced functional materials industry serving sectors including electric vehicles and renewable energy.    Digitalization is also changing traditional manufacturing. Guizhou Tyre's intelligent plant was the first in China's tyre industry to join the World Economic Forum's Global Lighthouse Network, which recognizes factories deploying advanced technologies at scale. The facility also uses photovoltaic power, purchased renewable electricity, and waste-heat recovery to reduce emissions.        Infrastructure played another role in connecting the mountainous province with wider markets. Nearly half of the world's 100 highest bridges are located in Guizhou, helping overcome terrain that has long complicated transport and economic connectivity.    For the visiting Gen Z group, the journey offered a view of China beyond its major cities and coastal manufacturing centres. Tea, badminton equipment, advanced materials, and tyres illustrate how specialised manufacturing, infrastructure investment, and local resources are connecting communities in China's mountainous southwest with national and global markets.                    。

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.
