Episode notes
Travel Experience Led To Phone Plan Recommendation
- Nick Martell recounts traveling for over a decade and noticing cheaper phone plans globally compared to the U.S.
- That experience led him to recommend Mint Mobile as a better, cheaper U.S. option.
Younger Dryas Was Abrupt And Globally Recorded
- The Younger Dryas was a rapid, severe cold snap that reversed post-Ice Age warming for ~1,200 years starting ~12,900 years ago.
- Multiple proxies like Greenland ice cores, lake sediments, glaciers, and cave records all show abrupt cooling and rapid end to the event.
Don’t Attribute Rapid Shifts To Orbital Cycles
- Do consider orbital cycles, but don’t blame Milankovitch rhythms for century-scale abrupt events like the Younger Dryas.
- Focus on faster forcings (meltwater, volcanic, impact) when seeking causes of quick climate shifts.
