Valerie Trouet: 树木年轮记录了气候、环境灾害和人类活动等信息,可以作为研究历史环境变化的重要资料。现代树轮研究起源于对太阳活动的研究,树木年轮的宽度、密度和化学成分等差异,可以反映树木生长环境的变化,例如气候、灾害等。利用树木年轮研究飓风,为研究飓风提供了新的方法和数据,可以将历史飓风数据的时间范围大大延长。 Latif Nasser: 树木年轮不仅能显示树龄,还能反映气候、环境灾害等信息。 Lulu Miller: 通过结合树木年轮数据和历史海难数据,科学家将加勒比海地区的历史飓风数据时间范围延长了近三倍。科学家在数据中发现了一个长达70年的飓风活动低谷期(1645-1715年),这个飓风活动低谷期与蒙德极小期(Maunder Minimum)相吻合,蒙德极小期期间较低的海洋温度可能导致飓风活动减少。当前全球气温创历史新高,这与太阳活动周期并不完全相关,人为导致的气候变化可能带来比蒙德极小期更严重的后果。 Grant Harley: 通过研究树木年轮,科学家推断出佛罗里达州的树木受到飓风的严重影响。 Marta Dominguez del Mas: 将树木年轮数据与历史海难数据进行比对,可以验证树木年轮中反映的飓风事件。 Matt Casey: 蒙德极小期期间飓风活动减少可能促进了黄金时代的海盗活动,加勒比海地区的糖业发展和奴隶贸易对世界历史产生了深远的影响,糖业发展和奴隶贸易为英国工业革命和现代资本主义的兴起提供了资金支持。蒙德极小期期间的平静天气环境为糖业发展、奴隶贸易和资本主义的兴起创造了有利条件。

Three dendrochronologists discover a connection between tree rings and a seemingly unrelated dataset, uncovering a natural force that has influenced human history and parallels current global changes.

Shownotes Transcript

At a tree ring conference in the relatively treeless city of Tucson, Arizona, three scientists walk into a bar. The trio gets to talking, trying to explain a mysterious set of core samples from the Florida Keys. At some point, they come up with a harebrained idea: put the tree rings next to a seemingly unrelated dataset. Once they do, they notice something that no one has ever noticed before, a force of nature that helped shape modern human history and that is eerily similar to what’s happening on our planet right now. With help from pirates, astronomers and an 80-year-old bartender, this episode will change the way you look at the sun. (Warning: Do not look at the sun.)
