&quot;But reading farther, the &quot;red flag&quot; seems more like a &quot;blazing conflagration&quot;. In the abstract, they explain that the reason that 1504 to 1515 is considered unreliable is because the written record says that lake didn&#x27;t freeze for those that 8 consecutive winters. They argue in the abstract that since this is so statistically unlikely, it must be wrong. So this paper is eliminating data as unreliable because of non-freezes, and then concluding that the current string of non-freezes is unprecedented!&quot; That&#x27;s hilarious. How on earth is that justifiable?
