Prof Paul Williams @profpaul.bsky.social · 17/02/2026

Great to speak at the Price Forbes Aviation Forum in Bogota earlier this month. I discussed air turbulence and climate change. How bad can it get? Potentially quite bad, I think...

Prof Paul Williams @profpaul.bsky.social · 20/01/2026

A tale of two press releases. One says the jet stream is slowing down, the other says it is speeding up. How can they both be right? In fact, as I explained in this talk at the Andorra Weather Meeting, there is no contradiction. The jet stream is changing in different ways at different altitudes.

Prof Paul Williams @profpaul.bsky.social · 19/01/2026

I enjoyed speaking about the jet stream and turbulence to weather presenters from around the world at the Andorra Weather Meeting this weekend!

Prof Paul Williams @profpaul.bsky.social · 19/12/2025

Great to spend a few days in Toulouse this week. The home of so many great things in aviation!

Prof Paul Williams @profpaul.bsky.social · 14/10/2025

Our new study finds that the upper atmosphere is becoming more sheared and less stratified because of climate change. Both these changes are making the air less stable and more conducive to turbulence. Published in the November issue of Journal of the Atmospheric Sciences. doi.org/10.1175/JAS-...

I love meeting face-to-face at in-person conferences. There's something magical about being physically present in the same place as like-minded people. Virtual meetings have their place, and favour a hybrid-first approach to maximise accessibility, but I will always choose to travel if I can.

Prof Paul Williams @profpaul.bsky.social · 16/07/2025

How is climate change affecting aviation? And how can the sector adapt? We had a stimulating Q&A session on these topics at an Airbus conference in Toulouse recently.

040

Prof Paul Williams @profpaul.bsky.social · 10/07/2025

Did you know that turbulence is the leading cause of weather-related commercial aircraft accidents? It accounts for 71% of them, according to a study we published in 2019, as I discussed at this recent presentation for Airbus in Toulouse.

041

Prof Paul Williams @profpaul.bsky.social · 08/07/2025

Is the jet stream speeding up because of climate change, helping eastbound flights reach record-breaking ground speeds? I discussed the evidence in this recent presentation at the Airbus Leadership University in Toulouse.

130

Prof Paul Williams @profpaul.bsky.social · 07/07/2025

It was a pleasure to share the stage with Camille Sagues and Veronique Roca at this recent Airbus event, discussing the crucial topic of adaptation of the aviation sector to climate change.

051

Prof Paul Williams @profpaul.bsky.social · 26/06/2025

I have been in Peru this week, to speak at an ICAO workshop on severe meteorological phenomena and aviation. It is great to see that the international aviation community is taking seriously the increasing risks of severe weather associated with climate change.

Prof Paul Williams @profpaul.bsky.social · 19/06/2025

I had the pleasure of speaking at a conference in Rimini this week about how aviation will need to adapt to climate change, covering the latest science on topics such as airport flooding, degraded take-off performance, more lightning, modified hail patterns, and stronger turbulence.

040

Prof Paul Williams @profpaul.bsky.social · 18/06/2025

We had a great aviation session at the European Climate Change Adaptation conference in Rimini this week. Thanks to fellow panellists Ian Elston, Davide Bassano, Marc Wetterwald, Robert Brons and moderator Rachel Burbidge for the stimulating discussions.

Happy memories of speaking about trends in weather-related aviation risks at the International Union of Aerospace Insurers (IUAI) conference in Prague last week.

120

Prof Paul Williams @profpaul.bsky.social · 05/06/2025

I am back home after spending a stimulating three days in Prague attending the IUAI Members Conference. It was a pleasure to reunite with old friends and make some new ones too!

120

Prof Paul Williams @profpaul.bsky.social · 03/06/2025

I am happy to be in Prague today, to speak to aviation insurers about long-term trends in turbulence and other hazards related to climate change.

Prof Paul Williams @profpaul.bsky.social · 29/05/2025

It's always good to be in Paris, especially when presenting our research on turbulence and climate change to the Air France KLM Group executive committee.

273

Prof Paul Williams @profpaul.bsky.social · 23/05/2025

I spent the week visiting Airbus in Toulouse, to discuss the consequences of increased turbulence from climate change. Exciting things are happening. Watch this space!

130

Prof Paul Williams @profpaul.bsky.social · 16/05/2025

It was great to give a climate change lecture to teenagers at St Albans School today. Will this be the generation that finally solves the climate change problem? Quite possibly, if the level of engagement during the Q&A session was anything to go by.

Prof Paul Williams @profpaul.bsky.social · 29/04/2025

I'm in Vienna this week at the General Assembly of the European Geosciences Union. You can catch me speaking tomorrow morning on "Jet streams in a changing climate: evidence for large increases in shear and turbulence since 1979". Full details: meetingorganizer.copernicus.org/EGU25/EGU25-...

Prof Paul Williams @profpaul.bsky.social · 25/04/2025

Our new study examines the impacts of geoengineering on future clear-air turbulence (CAT) increases. Injecting sulfate aerosols into the stratosphere, to counteract global warming, would reduce severe CAT trends by the end of the century from around 80% to around 40%. doi.org/10.1029/2024...

Prof Paul Williams @profpaul.bsky.social · 02/04/2025

Climate change denier doesn't know the difference between velocity and acceleration. Absolute shocker!

Prof Paul Williams @profpaul.bsky.social · 27/03/2025

I am happy to share that I was the top University of Reading media spokesperson in 2024. In these times of fake news and alternative facts, I am delighted to play my small part in communicating authoritative information about atmospheric science and climate change to the general public.

Powerful words from the American Geophysical Union.

Prof Paul Williams @profpaul.bsky.social · 03/03/2025

Yes, they are right actually! Also, despite its name, PragerU is not an academic institution and does not confer degrees. Best to trust proper universities with proper professors, and not these absolute jokers.

171

Prof Paul Williams @profpaul.bsky.social · 25/02/2025

It most certainly should not be flying in a straight line. Flying along that southerly route, it enjoyed a 100 knot tailwind from the jet stream, saving fuel and arriving early. But sure, Elon, you know best!

Prof Paul Williams @profpaul.bsky.social · 10/02/2025

I had a very enjoyable time in Bogotá last week, speaking at the Price Forbes LatAm Airline & Operators Forum about trends in weather-related aviation hazards, and setting out the evidence that climate change is increasing aviation turbulence.
