A new study finds that partisan conservative media led to "hurricane skepticism" among Trump voters before Hurricane Irma hit Florida in September 2017, discouraging evacuations.

Why it matters: As the divided response to the coronavirus pandemic underscores, how we view the world politically is increasingly determining how we view the threat of natural catastrophes. With extreme weather on the rise, that's a dangerous recipe.

What's happening: In a study published Friday in Science Advances, researchers from UCLA examined evacuation patterns for the hurricane using GPS phone location data from each affected voting precinct, which allowed them to compare the behaviors of likely Clinton and Trump voters living as closely as 500 ft. apart.

  • They found Florida residents who voted for Donald Trump were between 10% and 11% less likely than residents who voted for Hillary Clinton to obey evacuation orders.
  • That partisan gap was not present during Hurricane Harvey in August 2017 or Hurricane Matthew in October 2016.

Context: The researchers theorize the partisan gap seen in Irma was due at least in part to conservative media pushing hurricane skepticism before the storm hit, casting doubt on official predictions of its severity and the need to evacuate.

  • They cite a broadcast from Rush Limbaugh a few days before the storm's arrival, where the conservative radio host blamed government officials and the media for overhyping the hurricane to "advance this climate change agenda."
  • While such "hurricane trutherism" existed in pockets before Irma, the researchers noted an unprecedented spike in Google searches for skeptic content in the days leading up to Irma.
  • Irma ultimately caused 123 deaths in Florida, and it was the most expensive storm in the state's history.

Of note: There is evidence that at least some people in Oregon are resisting evacuations from the state's wildfires in part because of baseless rumors that left-wing activists are setting the fires so they can loot abandoned houses.

The bottom line: It's frightening to realize a growing number of Americans trust partisan media over authoritative sources — even in matters of life and death.

Three deaths have been linked to former Hurricane Delta, as PowerOutage.us reported over 100,000 customers remained without power in Louisiana on Tuesday morning — four days after the storm made landfall in the state.

Details: Louisiana officials said Sunday a man, 86, died while refueling a generator in a shed that caught fire and a woman, 70, died in a fire "likely caused by a natural gas leak following damage." In the Florida Panhandle, Okaloosa County sheriff's office said a 19-year old Illinois tourist drowned Saturday "after being caught in a rip."

CEO confidence skyrockets on expectations of layoffs and wage cuts

U.S. consumers remain uncertain about the economic environment but CEOs are feeling incredibly confident, the latest survey from the Conference Board shows.

Why it matters: Confidence among chief executives jumped 19 points from its last reading in July, rising above the 50-point threshold that reflects more positive than negative responses for the first time since 2018.

Louisville officer: "Breonna Taylor would be alive" if we had served no-knock warrant

Sgt. Jonathan Mattingly, the Louisville officer who led the botched police raid that caused the death of Breonna Taylor, said the No. 1 thing he wishes he had done differently is either served a "no-knock" warrant or given five to 10 seconds before entering the apartment: "Breonna Taylor would be alive, 100 percent."

Driving the news: Mattingly, who spoke to ABC News and Louisville's Courier Journal for his public interview, was shot in the leg in the initial moments of the March 13 raid. Mattingly did not face any charges after Kentucky Attorney General Daniel Cameron said he and another officer were "justified" in returning fire to protect themselves against Taylor's boyfriend.
