当地居民洛伦佐·巴尔拉托40多年前在"情人拱门"附近向妻子求婚,后来两人经常回到那里进行周年纪 念。得知拱门坍塌,他在社交媒体上说:"我非常想回到那里,可惜,现在我只剩下那片'天堂'的美照 了。" 奇斯泰尔尼诺说,由于气候变化,"情人拱门"坍塌是一场"难以避免的悲剧",只是没想到"这一天来得 如此之快"。 意大利萨伦托半岛海岸边有一处象征永恒之爱的"情人拱门",多年来一直吸引众多有情人前来"打卡"。 但在今年2月14日西方情人节当天,这座拱门因狂风暴雨的侵袭彻底坍塌。 据美国有线电视新闻网17日报道,这一天然岩石拱门位于普利亚大区梅伦杜尼奥镇,是海蚀柱群的一部 分。当地传说,恋人若在"情人拱门"下亲吻就可以永不分离,早在18世纪,就有许多情侣慕名而来,在 拱门处山盟海誓。近些年,在社交媒体的推动下,"情人拱门"更是成了打卡胜地。周边以"情人拱门"命 名的酒店和度假村也如雨后春笋般出现。 受全球气候变化影响,海水温度上升加剧了海岸侵蚀,极端天气也越来越频繁,拱门结构逐渐变得岌岌 可危。2024年,当地本想对受侵蚀严重的拱门实施保护,但因为资金未到位而作罢。今年1月,一场冬 季风暴对拱门造成破坏性打击。2月,意大 ...

南极冰山是全球气候"晴雨表" 我国海洋卫星1米C-SAR卫星持续监测发现,位于南极的世界最大冰山A23a冰山正加速崩解,2025年4 月以后,A23a冰山不断破碎出小的冰山,且在洋流作用下,围绕地处南大西洋的南乔治亚岛漂移。 "南极冰山破碎原本是冰架受外力作用、裂缝扩展等影响产生的自然物理过程。但全球变暖显著削弱了 冰架稳定性,加剧了崩解的频率与规模。"国家卫星海洋应用中心极地遥感监测部高级工程师曾韬说。 南极冰山对全球气候具有重要调节作用,并会产生一系列连锁影响。国家卫星海洋应用中心极地遥感监 测部主任石立坚说,冰山崩解进入海洋后逐渐融化,会造成全球海平面上升,冰山漂移还会阻断企鹅等 极地动物的觅食路径,威胁其生存。 不仅如此,由于南乔治亚岛设有英国南极考察站,且周边海域渔业资源丰富,有一定数量的科学考察和 渔业捕捞船舶,这些破碎的冰山可能会对航运安全构成威胁。 新华社北京2月4日电 题:解码洞察南极冰山变化的"千里眼" 新华社记者刘祯、顾天成 作为淡水载体,南极冰山是全球气候的"晴雨表"。南极冰山的每一次崩解,都深刻影响着全人类的安全 与发展。 如今,我国海洋卫星家族共同构建起极地冰山的观测网络,作为人类 ...

Core Viewpoint - The article discusses the complex historical and strategic relationship between the United States and Greenland, emphasizing the need for a responsible approach to the region amid climate change, rather than aggressive territorial claims or resource exploitation [1][18]. Historical Context - The U.S. has a long history of interest in Greenland, dating back to early 20th century explorations and resource extraction, including the controversial actions of naval officer Robert Peary [5][6]. - During World War II, Greenland was strategically important for the U.S. military, serving as a base for operations and weather data collection [7][9][10]. - The Cold War era saw ambitious military projects in Greenland, including the construction of Thule Air Base and plans for nuclear facilities, which ultimately failed due to environmental challenges [11][13][14]. Current Situation - The article highlights the ongoing issues related to abandoned military sites and the environmental impact of past U.S. activities in Greenland, which have left behind significant waste [16][18]. - Recent climate change has accelerated the melting of Greenland's ice sheets, posing risks to global sea levels and infrastructure [19][20]. Strategic Importance - Greenland's ice sheets are deemed more valuable than its potential mineral resources, as their melting could lead to catastrophic global consequences [19][20]. - The U.S. and Denmark are currently conducting geological surveys to identify mineral deposits, but mining activities remain limited and focused on specific resources [18]. Conclusion - The article argues that the most prudent strategy for the U.S. regarding Greenland is to prioritize the protection of its ice sheets and address climate change, rather than pursuing short-term economic gains through resource extraction [20].
