I 5 punti lagrangiani del sistema Sole-Terra
Gravity creates five special locations in the Sun–Earth system where a small object can maintain the same position relative to both bodies as they orbit. These are called Lagrange points. L1, L2, and L3 lie along the Sun–Earth line, while L4 and L5 form equilateral triangles with them. In the rotating reference frame, gravity and the centrifugal effect balance at these locations. The James Webb Space Telescope orbits around L2 rather than remaining exactly at the point. This geometry allows it to stay near Earth while maintaining a favorable position for observing the universe.

Quanto tempo perso per contrastare le interferenze ideologiche nella scienza... 😔

Che fatica…
#Isaias is now a #hurricane - the first of the 2026 Atlantic season. The last season with zero Atlantic hurricanes was 1914. Of course, our observational system is much better now than it was in 1914, so we may have missed hurricane(s) that year.

Non c’è bisogno di fare guerre ideologiche e tantomeno di buttare il bambino con l’acqua sporca, ma i fatti sono fatti, sempre, quando si fanno le serie storiche e quando si trovano queste evidenze.
Let me get this straight… We're told today's temperatures are the hottest in 125,000 years, yet melting glaciers in the Swiss Alps are revealing human artifacts thousands of years old. So what exactly is the theory here? That ancient humans were living UNDER the glaciers? Building little igloos beneath hundreds of feet of ice? 😂 Or is it possible that these areas were once ice-free, that glaciers subsequently advanced over them, and that Earth's climate has been changing dramatically long before SUVs, coal plants, and private jets? Apparently, climate history only counts when it supports the narrative. The planet has never been static. Stop pretending it was.

E come darle torto…
Well I love the cartoon. And I applaud @RogerPielkeJr for continuing to fight the good fight. But I am so over this stuff. The climate wars and attacks on scientists that challenge the mainstream narrative continue, but may be muted during the Trump regime (I admit I have lost touch with what is going on in academia, but I suspect things haven't improved). Academia has suffered from the loss of myself, Pielke, others, not to mention the scientists that rejected the academic path or left very early on in their tenure. While I will continue to set the record straight if I am asked (e.g. such as the DOE CWG), I've pretty much removed myself from the public debate on this topic (particularly after shutting down Climate Etc), apart from sporadic tweeting. In the meantime, I am working in the private sector (Climate Forecast Applications Network) which allows me to bypass all the BS of peer reviewed journal publication, government grant applications, and generally playing the game to build academic prestige. Academics waste a colossal amount of time on that stuff. Pielke is bypassing all that with his substack, sustaining his reputation and profile in the public debate. I have taken a different path. I am bypassing all that by doing client-driven research to help companies and governments understand and manage their extreme weather and climate change risks (timescales from days to decades). I have done some path breaking work in this regard, which is to the great benefit of my clients but unknown to the broader academic community. So Michael Mann and the rest of that gang can go suck eggs, their path to irrelevance grows with every passing day. It's sad for academia and the education of the future generation of scientists. But the real action these days is in the private sector (e.g. the AI weather forecast models) and on social media. rogerpielkejr.substack.com/p…

Uragano cercasi.
We have made it through September without a single hurricane forming in the North Atlantic. This has not happened since at least 1914 (although the lack of satellite observations before 1966 means that pre-1966 NOAA HURDAT2 best track data has significant uncertainty and data gaps, and those gaps widen the further back in time one goes). The only other two times that this may have occurred were in the 1905 and 1907 Atlantic hurricane seasons, respectively. Like 1914, the 1907 season featured no hurricanes that we know of by year end. The first (and only) hurricane to form in 1905 was on October 8th. With no new named storm formations expected for at least the next seven days, we could very well match or eclipse 1908. Tying 1907 and 1914 in terms of having zero hurricanes is also on the table, but I cannot rule a hurricane or two out yet. October and November can throw us curveballs, but with El Niño strengthening in the equatorial Pacific (yielding higher vertical shear in the North Atlantic) and climatology, odds increasingly are in our favor to go the entirety of 2026 without one hurricane in the Atlantic. Pretty incredible stuff from a meteorologist's POV.

"Establishment" climate science is so sick. Note: NASEM refers to the US National Academies on Science, Engineering and Medicine
Wow NASEM scandal gets worse In March I documented that a lawyer representing plaintiffs in climate litigation had ghost written a NASEM/FJC chapter on climate science for federal judges House Judiciary just released a report with the smoking guns It’s even worse than I claimed judiciary.house.gov/media/pr… rogerpielkejr.substack.com/p…

🚨 The “planetary boundaries” game is remarkably convenient. Scientists define precautionary boundaries that are not actual physical tipping points. We cross their chosen line. The graphic turns red. It gets called a “planetary emergency.” And, surprise, we're told more research, programs and funding are urgently needed. Meanwhile, Earth history contains climates and ocean conditions far outside many of these preferred ranges while complex life persisted and diversified. This isn't a planetary dashboard handed down by nature. Humans chose the boundaries. Humans chose the thresholds. Then humans declared crossing them an emergency. That deserves scrutiny... especially when the institutions sounding the alarm also benefit from continued funding to study it. livescience.com/planet-earth…

Interessante punto di vista. E se fosse davvero l'ora di cambiare?
Je ne sais pas si vous mesurez ce qui est en train de se passer. Alex Karp, le patron de Palantir, ne va plus chercher ses talents à Harvard. Il les forme lui-même. Des jeunes de 18 ans, sans diplôme, choisis sur leur seul talent, qui codent sur de vrais projets et lisent de la philosophie politique entre deux sprints. Il appelle ça « le diplôme Palantir ». Et aujourd'hui le New York Post titre que les boîtes tech lancent leurs propres programmes parce qu'elles ne peuvent plus compter sur l'Ivy League. Ce n'est pas une anecdote RH. C'est un basculement de civilisation. Pendant des décennies, les entrepreneurs ont confié à l'université la mission la plus sacrée qui soit : former les esprits. Ils comprennent aujourd'hui que cette mission a été trahie. Les institutions censées produire des penseurs libres produisent des conformistes. Le mérite a été remplacé par des critères opaques. L'enseignement est devenu catéchisme. Paul Graham l'avait vu avant tout le monde. Alors ils font ce que font les bâtisseurs quand un système les trahit. Ils ne le réforment pas. Ils en construisent un autre, à côté. Elon n'a pas attendu que la NASA se réveille, il a fait SpaceX. Il n'a pas réformé les médias, il a racheté la place publique. Les entrepreneurs ne cherchent plus à convaincre l'État. Ils font l'État, partout où l'État a abdiqué. Relisez La Grève d'Ayn Rand. Nous y sommes. Les bureaucrates gardent les titres, les budgets, les bâtiments. Mais ils perdent la seule chose qui compte : la confiance. Aux États-Unis, à peine 28 % des gens font encore confiance aux médias. Un plus bas historique. Plus personne ne croit ceux qui prétendent nous dire quoi penser. On entend partout que l'école est finie. Je pense exactement l'inverse. Ce n'est pas l'école qui est morte. Ce sont les institutions qui l'ont confisquée. L'école, la vraie, celle de l'Académie d'Athènes, des ateliers de la Renaissance, du maître et de l'apprenti, va renaître. Plus exigeante. Plus juste. Sans dette, sans dogme, sans diplôme comme rente à vie. Une école qui ne fabriquera plus des diplômés, mais des polymathes. Des esprits libres, capables de coder, de penser, de construire et de douter. Ce sont eux qui créeront la valeur des cinquante prochaines années. J'ai appris à coder seul à 12 ans. Aucun amphi ne m'a appris ce que j'ai appris en construisant. Je sais ce que devient un talent quand on le laisse respirer. L'université a eu des siècles pour former les meilleurs esprits. Les entrepreneurs vont le faire en une décennie. La grande reconstruction a commencé.
