Penn State scientist Michael Mann posted a short primer on Facebook that describes the connection between the devastating storm and global warming. While climate change didn't "cause" the storm, it's worsening the impact in several ways, he says.

  • Rising waters: Sea level rise attributable to climate change (some is due to coastal subsidence due to human disturbance, e.g. oil drilling) is more than half a foot over the past few decades. "That means that the storm surge was a half foot higher than it would have been just decades ago, meaning far more flooding and destruction."
  • Warmer waters: The rise in sea surface temperatures in the region by about a half-degree celsius in recent decades has led to a roughly 3% rise in atmospheric moisture content. "That large amount of moisture meant the potential for much greater rainfalls and greater flooding," Mann writes.

President Trump's suburbs

President Trump cast an outdated vision of "the 'suburban housewife'" as he swiped this week at Joe Biden's newly minted running mate Kamala Harris — building on his months-long play to drive a wedge through battleground-state suburbs by reframing white voters' expectations.

The big picture: As he struggles to find an attack that will stick against the Biden campaign, Trump for a while now has been stoking fears of lawless cities and an end to what he's called the “Suburban Lifestyle Dream.” It’s a playbook from the ‘70s and ‘80s — but the suburbs have changed a lot since then.

Trump tightens screws on ByteDance to sell Tiktok

President Trump added more pressure Friday night on China-based TikTok parent ByteDance to exit the U.S., ordering it to divest all assets related to the U.S. operation of TikTok within 90 days.

Between the lines: The order means ByteDance must be wholly disentangled from TikTok in the U.S. by November. Trump had previously ordered TikTok banned if ByteDance hadn't struck a deal within 45 days. The new order likely means ByteDance has just another 45 days after that to fully close the deal, one White House source told Axios.
