Core Insights - The World Meteorological Organization (WMO) has included the China-MST3.0 dataset in its 2025 global temperature change report, confirming that 2025 will be one of the three warmest years on record [1][5] - The China-MST3.0 dataset, developed by a team from Sun Yat-sen University, has become a key data source for international climate reports, contributing to global climate governance [1][5] - The dataset addresses challenges in global temperature monitoring, such as historical observation inconsistencies and sparse data in high-altitude and polar regions [1][3] Group 1: Dataset Development - The China-MST dataset was first launched in 2019, integrating land and ocean temperature data to improve accuracy [2] - The 2.0 version released in 2022 enhanced data for ice-covered areas and improved coverage in sparsely observed regions [2] - The 3.0 version introduced a comprehensive uncertainty assessment framework, significantly improving data quality and reliability [2][3] Group 2: Global Temperature Trends - The evaluation based on the China-MST3.0 dataset indicates a global average near-surface temperature increase of 1.07°C ± 0.05°C compared to the 1961-1990 climate standard, and 1.39°C ± 0.13°C compared to pre-industrial levels [5] - The analysis from eight datasets shows a clear trend of global warming, with an acceleration in warming rates beyond previous expectations [5] Group 3: Future Directions - The research team is focusing on developing higher-resolution climate application datasets and has recently completed a homogenized global solar radiation dataset [6] - The team aims to enhance data quality standards and strengthen international collaboration in climate research [6]

中国气象科学研究院研究显示，在《巴黎协定》设定的2℃温升情景下，整个南极地区将出现稳健 的增暖信号，其整体增温幅度是南半球平均的1.4倍。 中国气象科学研究院全球变化与极地研究所所长 研究员 丁明虎：由于南半球咆哮西风带的隔离作 用，人类活动的影响，主要是通过海洋表面的升温将热量传输到南极，这也是为什么南极变暖滞后于全 球其它地区的原因。同时，我们还发现，由于海温持续升高，未来南极也会像北极一样，逐步出现放大 效应，也就是增暖速度会加快。这项研究的意义： 一是确认了南极出现整体增温的现象； 二是证明了南极放大效应的存在，只是仍然需要数十年时间显现。 极地作为气候变化的敏感区，在全球持续增暖背景下，其增温幅度将显著高于全球水平，这一现象 被称为"极地放大效应"。北极放大效应已较为明确，而南极放大效应的存在与成因仍有争议。 近日，记者从中国气象局了解到，中国气象科学研究院冰冻圈与极地气象研究团队的最新研究，明 确证实了未来南极增暖放大效应的存在，并进一步揭示了其驱动机制。 全球变暖背景下，北极海冰快速消融，北极地区的气温升高速率是全球平均的4倍，但是过去几十 年南极一直没有发现全域变暖甚至十几年前东南极冰盖有轻微 ...
