Column by Daniel Wolfe | Clear-air turbulence has increased since the 1970s. Researchers agree that the likelihood of severe turbulence will only increase in a warming world, putting passengers and crew at risk.

The results of a study in npj Climate and Atmospheric Science shows that ongoing and frequent rocket launches could delay ozone recovery. The authors call for action to ensure that future growth of the launch industry and ozone protection are mutually sustainable. 🧪
Near-future rocket launches could slow ozone recovery - npj Climate and Atmospheric Science
Rocket emissions thin the stratospheric ozone layer. To understand if significant ozone losses could occur as the launch industry grows, we examine two scenarios. Our ‘ambitious’ scenario (2040 launches/year) yields a −0.29% depletion in annual-mean, near-global total column ozone in 2030. Antarctic springtime ozone decreases by 3.9%. Our ‘conservative’ scenario (884 launches/year) yields −0.17% annual, near-global depletion; current licensing rates suggest this scenario may be exceeded before 2030. Ozone losses are driven by the chlorine produced from solid rocket motor propellant, and black carbon which is emitted from most propellants. The ozone layer is slowly healing from the effects of CFCs, yet global-mean ozone abundances are still 2% lower than measured prior to the onset of CFC-induced ozone depletion. Our results demonstrate that ongoing and frequent rocket launches could delay ozone recovery. Action is needed now to ensure that future growth of the launch industry and ozone protection are mutually sustainable.

We know that training models on generated content causes model collapse (see autophagy).
So ironic: the more people populate the Internet with the results of these models put to their intended use, the less useful the internet becomes for training the next generation models.

It always boggles my mind that I, a journalist, am expressly forbidden from trading stocks, but members of Congress, with vastly greater knowledge of market-moving news, are allowed to profit by front-running markets, and so may profit by in essence stealing from the public they represent.

A reminder that if the government can send migrants to a prison camp without any due process, it can send U.S. citizens there, too. I know because this happened to me and my family in 1942.

The number of working satellites has soared in the past five years to around 11,000, mostly because of constellations of orbiters that provide Internet connectivity around the globe, but it comes with a series of problems. Nature explores the issues and how scientists are reacting. 🔭 🧪
Swarms of satellites are harming astronomy. Here’s how researchers are fighting back
SpaceX and other companies plan to launch tens of thousands of satellites, which could mar astronomical observations and pollute the atmosphere.
