Good morning.

We’re covering the latest personnel change in the Trump administration and the worrying price of pork in China. We’ve also got two juicy interviews with Joaquin Phoenix and Jennifer Aniston.

Mr. Bolton objected to Mr. Trump’s attempts to pursue diplomatic avenues with players long considered American enemies. And he angered Mr. Trump with a last-minute battle against a peace agreement with the Taliban, which the president dropped for other reasons.

Mr. Trump said he would appoint a replacement in the “next week.”

Mr. Bolton handed in his resignation letter on Tuesday. A Fox reporter tweeted it.

Related: The Trump administration’s decision to pull the plug on negotiations with the Taliban at Camp David inadvertently provided the Afghan president, Ashraf Ghani, with a lifeline, bringing his re-election bid back into the spotlight.


The higher grocery bills have frustrated Chinese consumers already burdened by the trade war with the U.S.

Officials have announced a raft of creative measures to tamp down anxiety, from tapping strategic pork reserves — yes, that is a thing — to emphasizing the virtues of a diet with less pork.

Supply constraints: One of the main factors that has affected pork supply is African swine fever, which first broke out in August 2018 and has since spread to all of the country’s provinces.

And China’s most recent round of tariffs, which came into effect on Sept. 1, made U.S. pork more expensive, along with U.S. soybeans to fatten Chinese pigs.


The tech giant dropped its annual goody bag of new gadgets and updates on old standbys, including three new iPhones aimed at drumming up sagging enthusiasm for its flagship moneymaker.

How we know: Our reporters interviewed current and former officials, who agreed to discuss classified information if their names were not used. They did not disclose the identity or location of the informant, whose life remains in danger.

The answer emerges from global phenomena. Radiation from the sun falls unequally on our tilted, spinning planet, hitting with most impact at the Equator. There, the hot air rises into the atmosphere and power tropical cyclones through evaporation and the Coriolis effect, the spin created by the Earth’s curvature.

Tropical cyclones in the Atlantic — hurricanes — are most likely to occur after surface temperatures peak and large amounts of moisture are already in the atmosphere. That season lasts from June to November, with the most perilous period from mid-August to mid-October.

Tropical cyclones in the northwestern Pacific — typhoons — can form year-round because of warmer waters, but they most commonly occur from May to October.

And global warming has increased the amount of energy absorbed by oceans, which scientists believe has resulted in stronger storms.


That’s it for this briefing. And sorry, another correction. Tuesday’s Back Story misspelled the surname of Alan Siegel, the brand consultant who devised the N.B.A.’s logo.
