Exceptional #stratospheric contribution to human fingerprints on atmospheric temperature: https://www.pnas.org/doi/10.1073/pnas.2300758120 -> A new study reaffirming that global #ClimateChange is human-made also found the #UpperAtmosphere is cooling dramatically because of rising CO2 levels: https://e360.yale.edu/features/climate-change-upper-atmosphere-cooling - scientists are worried about the effect this cooling could have on orbiting satellites, the ozone layer, and Earth’s weather.

In "Envisioning a #sustainable future for #space launches: a review of current research and policy", we look at how launch emission products have effects on #stratospheric #chemistry. As the number of launches scales up, this can start to impact #ozone https://theconversation.com/a-rapidly-growing-rocket-industry-could-undo-decades-of-work-to-save-the-ozone-layer-unless-we-act-now-198982

#DidYouKnow: #AirBus #Zephyr is the first #Stratospheric Unmanned Aircraft Systems (UAS) of its kind.

It's latest model is a high-altitude platform station (HAPS) capable of flying at 70,000 feet (21,000 m) for months at a time without fueling.

For the third year in a row we are seeing the #Antarctic #OzoneHole persisting well into late November, and possibly December, due to low #stratospheric temperatures and a strong polar vortex. #CopernicusAtmosphere monitoring of the #OzoneLayer shows 2022 following a similar trend to 2021 and 2020 with the area (temperature at 50hPa poleward of 60S) well above (below) the 1979-2019 average size.

3 months later, the final OA v of this is finally out ;) 👉 https://iopscience.iop.org/article/10.1088/1748-9326/ab94eb a great team effort with geochemists, ecologists & other experts to try n answer the q: "would the increased deposition from #stratospheric #sulfate #injections be harmful for soils & humans?" https://twitter.com/DanVisioni/status/1266382535740833792
