世界气象组织发布报告强调 应对气候变暖面临更大挑战
世界气象组织 气候变暖 水文研究
2020/7/14
世界气象组织日前发布的最新气候预测报告指出,2019年是全球有气温记录以来第二热的年份,仅次于2016年。由于温室气体水平持续上升,新的“史上最热年度”可能在5年内出现。世界气象组织警告称,实现应对气候变化《巴黎协定》确定的温控目标面临巨大挑战。

几十年减排难改全球气温(图)
几十年 减排 全球气温
2020/7/8
大规模减少人类排放可能要几十年的时间才能让全球地面温度出现可检测的变化。7月7日刊登于《自然—通讯》的这些结果表明,减缓气候变化需要付出长期努力,因为短期努力难以看到效果。尽管减少人为排放是缓解全球变暖必需条件已成为了普遍共识,但大气可能出现变化的时间尺度尚不明确。公开讨论中有观点认为减排可以立即影响全球变暖,但气候系统惯性强、固有背景噪声大,这些特点会掩盖突然改变对气候系统的短期作用。虽然此前针...

近日,美国国家航空航天局(NASA)和美国内布拉斯加大学发布全球地下水地图,帮助监测全球干旱状况。在地表,土壤水分随天气条件的改变而迅速变化;根区土壤(土壤最上层90厘米左右)的水分变化稍慢,但仍对天气非常敏感;最不敏感的是地下水,因为它不受天气变化的影响。地下水通常是作物灌溉的水源,在干旱期,地下水仍能保持一定的流量。对于预测长期旱情或低洼地区的洪水风险而言,地下水是值得关注的重要指标。

气候科学研究遭遇“疫情风暴”(图)
气候科学 疫情风暴 气象数据量

“如果没有疫情,我现在应该在海上了。”美国俄勒冈州立大学的埃德·德维尔领导的小组每年都会由俄勒冈州和华盛顿海岸出海,翻新和清洁100多个精密传感器。这些传感器是每年耗资4400万美元的“海洋观测计划”科学网络的一部分。但现在,他只能和很多科学家一样,眼睁睁看着珍贵的数据流失,对于仪器性能下降也束手无策。英国《自然》杂志网站在4月13日的报道中指出,随着气候和生态监测项目因为新冠肺炎疫情偃旗息鼓,气...

百年生态学模型显示: 气候变化或致种群破坏骤然发生
生态学模型 气候变化 种群破坏
2020/4/9
英国《自然》杂志8日发表的一项生态学模型研究显示,气候变化造成的物种种群破坏,最早或在这个10年内发生,并且会是“骤然”发生。但大规模、快速地降低温室气体排放,则有可能降低生态组合遭遇突然性破坏的几率。环境危机有两个彼此息息相关的要素:气候变化和生物多样性丧失。全球气候变化影响生物多样性,从而影响可持续发展;反之,作为地球生命的基础之一的生物多样性也影响着全球气候变化。
