RC and crew continue to review and discuss the scientific papers that have compiled evidence in support of a major catastrophe at the Younger Dryas Boundary. The Channel Islands off the southern California coast reveal massive fires and floods at that time and a quick shift from forests to grasslands. We puzzle over critics who attribute the transitions to climate change, but don’t consider what forces may be driving that climate change, which prompts Randall to look at the unlikely hypotheses about the repeated filling and draining of Lake Missoula, asking: What conditions allowed that basin to be filled up to the first order stream level? We then get into a 2018 paper authored by many from the Comet Research Group addressing “Extraordinary Biomass-burning Episode and Impact Winter… ~12,800 years ago.”   Support Randall Carlson's efforts to discover and share pivotal paradigm-shifting information!
