Episode notes
Why Russia's Earthquake Had Small Tsunami
- The magnitude 8.8 earthquake near Russia's Kentucky Peninsula caused relatively minor tsunami waves despite its strength.
- The non-linear scale between magnitude 8.8 and 9.0 explains the smaller tsunami compared to the 1952 event.
EPA's Climate Policy Reversal Move
- The EPA moved to repeal the 2009 endangerment finding that allowed CO2 regulation as pollutants.
- The proposed repeal is based on a report challenging climate change consensus despite expert opposition.
Benefit of Brisk Walking
- Walking briskly for just 15 minutes a day can reduce mortality risk by almost 20%.
- Even slow walking helps, but faster walking provides significantly greater longevity benefits.
