Climate change, human activity causing global water cycles to become 'increasingly erratic': World Meteorological Organization_我的网站

一 |     近日，某韩国大型存储企业正在开发面向AI存算扩展应用的新一代内存控制芯片，旨在满足AI大模型训练与推理场景对大容量、高带宽及高能效内存系统不断增长的需求。    Climate change and human activity are causing the world's hydrological cycle to spin out of balance, according to a new report from the World Meteorological Organization.Global water cycles are becoming "increasingly erratic" due to droughts, extreme rainfall and the increased melting of snow, ice and glaciers -- all of which are a threat to long-term water security, the 2022 State of Global Water Resources report, released Thursday, found.About 3.6 billion people already face inadequate access to water at least a month per year, according to the United Nations. That number is expected to increase to 5 billion by 2050, officials said.Extreme glacier loss is occurring from the Tibetan Plateau to mountain ranges in the Himalayas, the Alps and the Andes -- all of which threaten the water security for millions of people who live on the rivers supplied by the melting."Glaciers and ice cover are retreating before our eyes," WMO Secretary-General Petteri Tallas said in a statement.In addition, rising temperatures have accelerated, causing the atmosphere to hold more moisture and facilitate more heavy downpour episodes that lead to flooding, Tallas said, adding that the "overwhelming majority" of disasters are water-related.More than 50% of the global catchment areas in large river basins experienced deviations from normal discharge conditions in 2022, according to the report. Most of these areas were drier than normal, but a smaller percentage of basins displayed above or much above normal conditions.Hotter temperatures are also causing more evaporation and much more intense droughts, Tallas said.Throughout 2022, anomalies in soil moisture and evaporation also experienced deviations, according to the report. Places like Europe saw increased evaporation and decreased soil moisture and river flows during the summer due to a major heat wave and drought, which led to challenges in agriculture as well as the shutdown of some hydrological power plants due to lack of cooling water, according to the report.Severe droughts impacted other parts of Europe in Summer 2022, posing transportation challenges on the Danube and Rhine rivers in Germany, and disrupting nuclear power production in France. In the U.S., the navigation on the Mississippi River was affected by extremely low water levels due to the continuous drought occurring in the region.The switch from La Nina in 2022 to El Nino conditions in 2023 will likely also have a major impact on water cycles around the world, the researchers said.The WMO is calling for improved monitoring and data-sharing across borders, as well as an increase in investments to facilitate international collaboration, in order to help society cope with increasing water extremes, whether it be too much or too little. They are also calling for more early warnings, and coordinated water management policy, according to the report.。该项目可适配包括CXL在内的新一代高速互连及内存扩展架构，为未来AI存储系统提供更高效、更灵活的内存解决方案。         经过严格的技术评估，该项目最终选用芯动科技符合JEDEC最新规范的Advanced LPDDR6/5X Combo PHY + Controller IP全套解决方案。此次合作充分体现了国际头部存储企业对芯动高速存储接口IP卓越PPA（Performance、Power、Area）表现、技术成熟度及工程交付能力的高度认可。                   芯动LPDDR6/5X IP能够在全球众多竞争方案中脱颖而出，关键在于其行业领先的PPA综合优势。方案严格符合JEDEC LPDDR6最新规范，单线IO峰值速率可达14.4Gbps，较当前主流LPDDR5X提升约50%；同时支持LPDDR5至LPDDR6全代协议兼容，可满足不同产品平台的灵活配置需求。
