An almost 1-year old interview on the role of AI for weather forecasting and climate predictions/projections for the @mm-ansa-bot.bsky.social Italian press agency. I was a bit offline recently!

Can climate models reproduce observed trends?

The answer can be challenging. Our new review paper in Science Advances led by Isla Simpson and Tiffany Shaw @drshaw.bsky.social discusses challenges and ways forward in confronting climate models and observations.

Da quando l’ho letta sul riassunto di un romanzo distopico qualche giorno fa, c’è una frase che non mi lascia più:

“Visto che la democrazia non interessava più a nessuno, il presidente la dichiarò abolita”

this poll says to me that a lot of americans just think everything is a TV show with zero consequence www.cbsnews.com/news/trump-a...

CBS News poll — Trump has positive approval amid "energetic" opening weeks; seen as doing what he promised

Trump's deportation plans are popular, but Americans say there's not enough focus on lowering prices.

Deep in the Canadian Arctic, scientists and entrepreneurs brave sub-zero temperatures, whipping winds and snowstorms to drill holes through the sea ice to pump out the seawater below and freeze it on the surface.

The group is trying to prove they can grow and restore Arctic sea ice.

It took a while, but we finally got to publish this meeting summary (that is also a bit of a perspective) from the community that took part to the workshop on Rossby waves, #heatwaves and compound #extreme #events, held at Bologna CNR research area in November 2023!

I am very happy to announce that I am convening a session at @eurogeosciences.bsky.social 2025 GA in Vienna!

If you are an expert on atmosphere-oceans interactions in the extra-tropics, you have time until 15th January 2025 to submit an abstract here: meetingorganizer.copernicus.org/EGU25/sessio...

The G20 has removed language calling for the "transition away from fossil fuels," agreed on at COP28, from its leaders' statement in Rio.

You can call this backsliding, or you can call it murderous indifference. Really, up to you.

The #climateactiontracker global update shows we are heading for around 2.7°C of warming by the end of the century, says Sofia Gonzales-Zuñiga, “the curve is not going down”.
apnews.com/video/floods...

Climate tracker suggests no improvement in Earth's projected warming for 3rd straight year

Climate scientists say the atmospheric warming, mainly from human burning of fossil fuels, is causing ever more extreme and damaging weather including droughts, flooding and dangerous heat.

Thank you @DaviFaranda and Gabriele Messori for allowing us to provide some views on what we have been doing in recent years...
And thanks Vera Melinda Galfi for bringing her expertise on EVT inside our analyses. Her contribution has been fundamental! https://t.co/0ncXDtpeJa

Valerio Lembo @valeriolembo.bsky.social · Nov 14

Let me recall something that she said in her Perspectives seminar in 2021, where she was invited as speaker, something that I consider now as a take-home message and a testament: "The path to a sustainable future goes through policies that truely address social inequalities."/END

Valerio Lembo @valeriolembo.bsky.social · Nov 14

She had an incredible talent, worked with some of the universally recognized pioneers of climate science, first female professor at MIT Department of Meteorology. Always generous and kind, supportive and encouraging./2

Ok... I would not consider 40 years of AMIP runs a groundbreaking step towards hybrid climate simulations, but results are certainly interesting! It might also be worth noting that not all dynamical cores are similar. Let us see where this hype is bringing us in the future! https://t.co/I4A08QP2bf
