Global stability is ‘fracturing.’ For Canada, the stakes are high, Joly warns
The current era of global stability, built from the ruins of the Second World War, is “fracturing,” Foreign Affairs Minister Melanie Joly warned Monday.
And for Canada, the stakes are high.

Yesterday's #flight was bumpy. Lumpy. Chunky. Objectively, it wasn't even moderate #turbulence. They just went on serving the coffee 🤷 In my head, though, it was awful. Still, it was probably good it happened, because I'm so used to smooth flights, my impression of turbulence is the equivalent of driving over cobblestones. I needed a corrective.

Climate change is making turbulence on flights worse, which in turn means you’re much more likely to suffer fools clapping and whooping when the plane lands successfully. Think on.

TURBULENCE (1997) was a decent 90s airplane film. Ray Liotta and Lauren Holly. Little heavy in the violence against women department, for a couple scenes.
#Physics question. Given an energy spectrum that is used a lot in #turbulence, E(k), such that Integral [ E(k).dk ] = Etot the total Energy, what is the typical velocity at wavelength k ?

Why Is #Turbulence Getting Worse? The Plane Experience is Getting Bumpy

Le laboratoire de physique est maintenant présent sur Mastodon!
Nos activités couvrent des domaines très variés, allant de la #physique statistique à la #turbulence #hydrodynamique, en incluant aussi la #physique mathématique et le traitement du signal, mais aussi la matière molle ou condensée. Cette pluridisciplinarité est notamment entretenue par la forte association du laboratoire avec la formation en physique à l’ENS de Lyon.
Comedian Dan Mintz (voice of the older daughter Tina on Bob's Burgers) shares this wise philosophy:
"I'm not usually religious. But one time I was on a plane that was going through some really frightening and violent turbulence. So, I immediately began taking rights from gay people."

Flying could get bumpier in the future. A new study suggests that climate change could increase the frequency and intensity of clear-air turbulence, an invisible and unpredictable air movement that can cause injuries and damage to planes. The study predicts that clear-air turbulence could increase by 60% by 2050 due to changes in atmospheric jet streams. This could affect the safety, comfort, and cost of air travel.

#Turbulence is a natural stage of fluid dynamics, in which a fluid displays (apparently) random fluctuations of velocity, as well as of other quantities, across a large range of scales.
But does "turbulent" really means “random”?
This is what this #AstroPhysicsFactlet is about!
Wrote this piece about the compounded effects of climate change on air travel two weeks ago @FortuneMagazine .

Interestingly, @WSJ published a piece about this yesterday, & the Today show did a feature on it today.
Bottom line: Best to buckle up!

Bumpy air, even violently bumpy air, is not all pilots are dealing with in a climate-changed sky.
It’s a “perfect storm kind of scenario,” says Shem Malmquist, a Boeing 777 captain, flight instructor, & veteran accident/ safety investigator.

With climate change, we are looking at "more storms, more lightning, & more turbulence."
How will this affect future air travel and what can you do to stay safe?

Here's another reason to take the #train, and to push for a #HighSpeedRail network:
"Although #turbulence often only causes a bumpy flight, its severity can vary greatly, harming the aircraft and injuring both passengers and crew in addition to inducing extreme anxiety and fear."
The article says that the #aviation industry is a "victim" of #climatechange.
It is not.
It is a culprit.
