公报解释，北半球1月严寒天气主要由短期大尺度大气环流异常导致。位于地表上空约8至12公里的极地 急流阶段性变得更为波动，使北极冷空气更易向中纬度外溢，导致寒潮出现。公报指出，近几十年来北 极变暖速度快于全球平均水平，北极与中纬度之间的温差变小，在一定条件下可能导致极地急流容易出 现更大幅度波动，从而增加冷空气外溢的可能性。 新华社布鲁塞尔2月10日电欧盟气候监测机构哥白尼气候变化服务局10日发布公报说，虽然今年1月多地 出现强寒潮等极端天气，但全球气候变暖总体趋势并未改变。 公报说，2026年1月为全球有记录以来第五暖的1月，该月全球地表平均气温为12.95摄氏度，较1991年 至2020年同期平均值高出0.51摄氏度，较工业化前（1850年至1900年）水平高出约1.47摄氏度。海洋方 面，1月南北纬60度之间海洋表面平均温度为20.68摄氏度，为有记录以来同月的第四高。赤道太平洋中 部和东部海表温度接近或略低于常年，反映出弱拉尼娜现象。 公报显示，1月中下旬北半球和南半球出现鲜明冷热对比：北半球的北美、欧洲和西伯利亚等地遭遇大 范围严寒；南半球多地出现破纪录高温并加剧极端气候情况，如澳大利亚、智利等地野火 ...

来源：中国新闻网 青藏高原冰冻圈消融致部分高原湖泊水位上涨 中新社西宁2月6日电 (记者 孙睿)记者6日从2026年青海省生态环境保护工作会议上获悉，全球气候变暖 趋势持续加剧，青藏高原冰冻圈消融，极端天气增多对生态环境改善和生态系统稳定产生显著影响，部 分高原湖泊水位上涨对重要基础设施的影响初步显现。 青藏高原作为"亚洲水塔"，其冰冻圈变化对区域乃至全球水文循环与生态系统具有深远影响。近年来， 受全球气候变暖驱动，青藏高原冰川加速消融、冰湖持续扩张，导致水资源失衡与灾害风险加剧。 2012年–2024年期间，青海地区典型冰川面积持续减少。其中，格拉丹东冰川面积变化最显著，累计减 少16.62平方公里；团结峰次之，减少15.40平方公里；阿尼玛卿和八一冰川的减少量相对较小；作为中 国西部重要的生态安全屏障，2024年祁连山国家公园青海片区典型冰川面积和冰储量与十年前(2015年) 相比，呈缩减态势；青海省气象科研人员于2025年对三江源海拔3600米以上核心区开展高寒湿地科考， 结果显示受气候变暖影响，青藏高原冻土退化促使热融湖塘发育扩张。 青海省生态环境厅厅长侯洪波表示，从面临的挑战来看，气候变化带来的生态 ...

新华社北京1月31日电 随着全球气候变暖，北极海冰融化，供北极熊活动的冰面逐渐缩小，不少人因而担心它们的生存。但研究人员惊讶地发 现，生活在挪威的北极熊"变胖了"。 挪威极地研究所资深科学家约恩·奥尔斯日前接受哥伦比亚广播公司采访时说："胖熊才是健康熊。" 研究人员认为，北极熊正在适应海冰面积缩小的情况。它们的猎物，如海豹等，因为海冰减少而集中在更小的区域内，可能有助于北极熊更高 效地捕猎。这也说明，"北极熊所需的海冰面积比我们想的要小"。 另外，海冰融化迫使北极熊不得不登上陆地，有些北极熊甚至九成时间都在陆地上活动，它们正在越来越多地捕食驯鹿和海象。 不过，奥尔斯也指出，这一现象虽然看起来是好事，但还必须进行更多研究，以弄清北极熊如何适应日益升高的温度。"目前的状况它们还可以 适应，"奥尔斯说，随着斯瓦尔巴群岛附近海冰进一步减少，还不清楚北极熊未来会怎样。科学家依旧担心，这一地带的北极熊长胖可能只是暂 时的，情况可能发生逆转。（荆晶） 这是2024年6月22日在挪威斯瓦尔巴群岛拍摄的冰山。新华社记者赵丁喆摄 1992年到2019年，奥尔斯和同事在挪威斯瓦尔巴群岛追踪研究北极熊，记录下将近800头北极熊的体重 ...

世界气象组织日前确认，2025年是有记录以来最热的三个年份之一，延续了全球气温屡创新高的趋 势。然而近期，北半球多地民众感到"瑟瑟发抖"：俄罗斯堪察加半岛持续遭遇极端暴雪天气、美国东北 部正在遭受大范围冬季风暴、欧洲也经历了一波寒潮、日本即将迎来多日强降雪……"最热"与"寒潮"， 看似矛盾，背后恐折射出全球气候变化的复杂影响。 世界气象组织14日发布新闻公报，确认2025年延续了全球气温屡创新高的趋势，预计2026年全球气 温大概率仍将处于"偏暖高位"。不少专家指出，全球气候变暖与多地遭遇严寒并不矛盾，两者之间还可 能存在关联。 北半球在冬季遭遇类似极端天气并不罕见，但频率有上升趋势。一些专家和研究认为，北极地区大 气环流的变化可能使冷空气更容易向南扩展，从而导致低温和强降雪天气的影响范围扩大、持续时间延 长。还有分析认为，由于全球变暖，海洋变暖加剧了水汽蒸发，导致气旋强度增加，增加了降雪量。美 国马萨诸塞大学阿默斯特分校气候系统研究中心助理主任迈克尔·罗林斯表示，全球变暖的确正在发 生，"但这并不意味着你不会遭遇这些极端寒潮"。 俄罗斯东部地区今冬降雪频繁，中东部地区气温比正常水平低7至10摄氏度。俄滨海边 ...
