你怎么知道二氧化碳水平的上升是人类活动造成的?
温室气体二氧化碳 （CO2） 是人类使用碳基燃料活动的产物，例如家庭供暖、汽车和制造厂等等。但二氧化碳也有许多天然来源，如土壤、火山和所有呼吸的生物。因此，气候学家和公民科学家等都应该问的一个问题是：“你怎么知道二氧化碳的增加是由人类活动造成的？”
科学家有两种方法可以测量二氧化碳的“人类”来源（我们称之为人源二氧化碳）和二氧化碳的“自然”来源（我们称之为生物源二氧化碳）。第一种方法是使用放射性同位素碳-14（或 14C）。这种同位素在某些情况下用于测定物体的年龄（因此有“放射性碳年代测定法”一词），也可用于测定大气中二氧化碳的年龄。测量二氧化碳的年龄对于确定多少二氧化碳是人源的，多少是生物源的有多大作用? 很多人源二氧化碳是化石燃料燃烧的结果，就像它的名字所暗示的那样，已经非常非常古老了（有数千万到数亿年的历史）。…
翼下吊舱、无人机与 NASA = 酷炫新科学
这里有两个简单却能唤起您回忆的短语。翼下吊舱。无人机。心动吗？至少我们是这样的。6 月下旬，日本宇宙航空研究开发机构 （JAXA） 与位于加利福尼亚州帕萨迪纳市的美国国家航空航天局 （NASA） 下属的喷气推进实验室 （JPL） 合作展开了 Railroad Valley 替代标定活动。作为该活动的一部分，来自 NASA 艾姆斯研究中心的一组顶级科学家部署了三台 Picarro 分析仪。其中一台部署在一架阿尔法喷气机的翼下吊舱中，飞上了 25000 英尺的高空。还有一台部署在一架无人机的鼻锥体上。第三台在地面上的帐篷里。这次演习令人印象深刻，我们从中采集到了一些数据。这张照片上是 NASA 有效载荷集成工程师Richard Kolyer（左）在 NASA 艾姆斯研究中心的飞机库里向 Picarro 研发总监Chris Rella（右）展示无人机设备。此外，我想补充的是，…
Nerdgasm! Building Cool Scientific Instruments, and the Joys of Innovation
