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.

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!
New paper alert!
Led by @valeriolembo.bsky.social we published a paper on Rossby waves #heatwaves and compound #extremes based on a nice workshop a year ago

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”.

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

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

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
