气候报告首次揭示全球洪涝脆弱性
气候报告 全球洪涝 脆弱性
2020/10/20
英国《自然·通讯》杂志近日发表的一项环境学报告称，全球有3.39亿人口居住在河流三角洲，其中89%的人口所居住的三角洲和大部分热带气旋活动处于相同的维度区域。鉴于未来沿海洪涝可能恶化，报告总结认为，洪涝将对居住在河流三角洲的人口造成不成比例的影响，尤其是对发展中经济体和最不发达经济体。河流三角洲由于海拔低，尤其易受沿海洪涝影响。此外，预计到本世纪末，热带气旋等事件将变得更加强烈。热带气旋是一种发生...

世界气象组织报告显示全球变暖加剧
世界气象组织 全球变暖 南极海冰面积
2019/4/1
世界气象组织28日发布的《2018年全球气候状况声明》显示，过去一年全球变暖仍在加速，为全球带来诸多经济社会方面的挑战。当天，世界气象组织秘书长彼得里·塔拉斯与联合国秘书长古特雷斯、第73届联合国大会主席埃斯皮诺萨一起，在纽约联合国总部发布了这份报告。报告显示，2015年至2018年是自有气温记录以来最热的四年，其中2018年是史上第四热的年份；当年全球平均气温较工业化前水平上升约1摄氏度；上层海...
改善水质可增强珊瑚礁恢复能力
改善水质 珊瑚礁'恢复能力
2019/3/18
英国《自然·生态与演化》杂志近日在线发表的一项研究指出，暴露在较差水质中的珊瑚礁受干扰后的恢复速度较慢，且更易受到珊瑚疾病的感染。但研究发现，改善当地水质或能帮助部分珊瑚礁更好地抵抗气候变化引起的白化，不过，这并不足以拯救那些最具标志性的珊瑚礁。气候变化和其他压力已经对大堡礁的大片区域造成了破坏。大堡礁未来的恢复力将取决于其抵抗干扰的能力以及珊瑚消失后的恢复能力。
植物物候学是气候变化的敏感指标，在调节植物碳吸收方面具有重要作用。以往物侯变化研究主要集中在春季温度和积雪融化时间的影响上，对于控制秋季叶片衰老时间的因素尚未明晰。中科院地理资源所研究员吴朝阳等联合国外专家开展的一项针对北半球植被秋季落叶期物候与昼夜温变化的研究有望填补这项空白，近日相关研究结果以《秋叶衰老对日、夜暖的响应对比》为题发表于《自然—气候变化》。
2018年6月7至8日，“共同行动以减轻咸海灾难后果：新方法、新技术与投资”国际会议在乌兹别克斯坦首都塔什干召开。会议旨在讨论咸海干涸对生态和社会经济的负面影响，达成实际行动的共同决定，并吸引投资；以期交流和讨论减轻生态灾难对咸海地区公共健康和环境负面影响的创新思维和新方法，实现改善该区域生态状况投资项目的落地。来自咸海地区周边国家政府、联合国系统机构、有关国际组织和基金会的代表，以及专家学者参加...
