Yesterday, I was reading about Britain’s newest prime minister and all the traditions that go along with the transition.

One of the first things every new prime minister must do is write the “letters of last resort” for each of Britain’s four submarines that continuously patrol the ocean while armed with nuclear weapons.

Each letter is handwritten, sealed, delivered to the sub’s commander, then locked in an onboard safe. It gets destroyed — still unopened — whenever a new prime minister takes office.

The letter tells the submarine commander what to do if Britain ever gets wiped out following a nuclear attack and nobody can be reached.

Do you fire the missiles? Or not.

BBC goes into detail about the letters here — including what a former PM wrote in his.

Today’s feature story is about the U.S. lawmakers who are upset that Canada’s wildfire smoke is invading their country.

Check it out below, along with our usual poll.

Have a great day,

Canada’s wildfire seasons are worsening, but its prevention and response systems haven’t kept pace.

With no national wildfire agency, aging aircraft, staffing gaps and provinces struggling to contain fires before they grow, critics say the smoke drifting south exposes a bigger problem. Better co-ordination and more prevention won’t stop every wildfire, but catching more fires early could mean less destruction — and yes, less smoke crossing the border.

Trump blames Canada for wildfire smoke drifting into American cities. But air pollution doesn’t need a passport.

U.S. wildfire smoke also crosses into Canada, while hotter, drier conditions are making wildfires worse on both sides.

Critics say tariffs and demands for more forest thinning ignore the bigger problem: climate change. Without cutting the emissions that create extreme fire conditions, neither country can manage its way out of the smoke.
