Today is the #UnitedNations International Day for the Preservation of the Ozone Layer. Stratospheric ozone is projected to recover during the 21st century following the restrictions imposed on CFC emissions by the Montreal Protocol. For more info un.org/en/observances… #OzoneDay

Very excited to start my Borysiewicz Interdisciplinary Fellowship and work with other Borysiewicz Fellows over the coming months!

Abstract submission open for #EGU23 session AS3.5 on composition-climate interactions. See meetingorganizer.Copernicus.org/EGU23/session/… On behalf of William Collins, Paul Griffiths, James Keeble, myself and Chris Smith 🇪🇺

Good news from #AMS2023: The ozone layer is on track to recover within four decades. Press release ➡️ bit.ly/3ZmSdPz Executive summary ➡️ bit.ly/3GlzTOe Partners 🤝🏽 UN Environment Programme, NOAA, NASA, European Commission

Ozone recovery is on track, thanks to the #MontrealProtocol But did you know these 4 facts? noaa.gov/stories/4-fact…

The full UN Environment Programme Scientific Assessment of Ozone Depletion, reviewing the latest research on stratospheric ozone, is now available! Working with so many excellent researchers has been a fantastic experience, particularly BirgitHassler, @pjyng and the rest of the Chapter 3 team!

Congratulations to Fouzia Fahrin on her new paper on unsupervised classification of ozone profiles in UKESM! Check out how the classes change with season, even appearing/disappearing over time Thx Alexander Archibald, James Keeble, and Yan Wu (@GSCOSM) ✨ acp.copernicus.org/articles/23/36…

📢 The #MontrealProtocol's Environmental Effects Assessment Panel's 2022 quadrennial assessment report on environmental effects of stratospheric ozone depletion, UV radiation, and interactions with climate change is now available. Get a copy here: bit.ly/3p70AkN
