Sudden Flood in Tibet: The 340th Evolutionary Lens with Bret Weinstein and Heather Heying

On this, our 340th Evolutionary Lens livestream, we discuss the recent flash flood on the border of Nepal and Tibet, climate science, and the nature of evidence. What commonalities are there between a glacial dam breaking and flooding the valley below, taking out towns and villages; Dry Falls and the Columbia River Gorge in Washington state; the Boxing Day tsunami in the Indian Ocean; and the 2011 earthquake that resulted in the destruction of the Fukushima nuclear power plant in Japan? In some cases we have to infer what happened; in some cases we have direct observation; in all cases we have to construct a plausible story that fits all of the evidence. Meanwhile in climate science, a new paper reconstructs NOAA data from 1,200 weather stations from over 100 years, uses a different metric than NOAA does to describe the data, and concludes that the world—or at least the coterminous U.S.—is not heating up in the way we have been told. We discuss.
