地球迎来有记录以来第二热3月
地球 记录 第二热3月
2020/5/7
在经历了创纪录的1月和第二热的2月之后，地球在上个月持续酷热，2020年3月成为有记录以来第二热的3月。根据美国国家海洋和大气管理局（NOAA）国家环境信息中心的数据，这也是迄今为止有气象记录以来第二热的年份。
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
2020/4/17
“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...
英国《自然·通讯》杂志近日发表一项环境学研究称，三叠纪末火山喷发向大气中释放的二氧化碳（CO2），可能与21世纪人为造成的CO2排放量预估值相当。如此大量的CO2可能促使了三叠纪末全球变暖、海平面上升和海洋酸化。
