1/n: Because of record-breaking diesel prices, the Trump Admin is reportedly considering a diesel export ban. There is one part of the country that this would squeeze tremendously, risking physical shortages that would prevent people from heating their homes in winter: New England (PADD 1A).

Not an exaggeration to say when authoritarian thugs distort scientific research toward their own petty or prejudiced tastes, economies suffer, national security is compromised, people die. Exact proportion of each of those consequences varies from one authoritarian state to another, but all happen

Damage assessments continue in Hawaii following the passage of Hurricane Lala. Much of the damage on Hawaii (island) is flood-related. The National Flood Insurance Program (NFIP) take-up rate on the island is less than 5%, which sadly means that a large portion of incurred damage will be uninsured.
