There is a cult of ignorance... nurtured by the false notion that democracy means that ‘my ignorance is just as good as your knowledge.’

Ce 19 septembre aurait été perçu comme une chaude journée du cœur de l'été au siècle dernier. Mais là, 37°C mi-septembre, et ça nous paraît normal.
Tout le début du mois est resté dans les normes… et puis, hop : il suffit que le vent bascule au sud pour que le thermomètre s’emballe.

El próximo 19 de septiembre, a plena luz del día, tendremos la ocultación de Venus por un fino menguante lunar.

🕑a las 14:20

Visible desde la península ibérica
Desde 🇮🇨 pasará pero sin ocultación con la estrella Régulo cerca.

Busca la fina luna menguante en el cielo...

Ocean Waves can be a source of unlimited #cleanenergy. This Wave Power Plant, could power thousands of homes.

We have the solutions to the #climateemergenecy. Stop the delays. Implement them. #ActOnClimate

La agencia France Press (AFP) dice que sin ayuda inmediata, sus periodistas en Gaza van a morir de hambre.

"Desde nuestra fundación en 1944, hemos perdido a compañeros en guerras, pero nunca muriendo de hambre".

El texto es tremendo.

Durante los próximos días los ojos deben estar puestos en el Mediterráneo.

La llegada de una potente vaguada (anómalamente intensa para la época) junto con el mar extremadamente cálido, provocará una situación muy energética, con potencial de tormentas altamente organizadas y muy virulentas.

Sigue los avisos de AEMET.

🇨🇳 CHINA IS TURNING ITS DESERTS INTO GIANT SOLAR FACTORIES

China is flattening massive chunks of desert to make room for solar panels. We’re talking enough to power entire cities.

Why? Because they want clean energy and fewer oil and coal headaches.

But here's the plot twist: these panels are also healing the desert.

By blocking harsh sun and holding moisture, they’re helping grass grow back in places that were nothing but dust.

So now China’s getting energy and land they might eventually use for farming or building whole towns on.

Turns out saving the planet might come with bonus real estate.

Cela peut vous sembler surprenant, mais les températures d'aujourd’hui sont exactement dans la moyenne d’un mois de juillet de la fin du XXe siècle.
➡️11 à 15°C le matin dans le nord, 20 à 27°C l’après-midi : c’étaient les normales estivales d’il y a 30 ou 40 ans.

Et pourtant, beaucoup trouvent ça "frais". C’est ce qu’on appelle le "shifting baseline" : le réchauffement climatique modifie peu à peu nos repères, au point qu’une journée normale d’autrefois nous semble aujourd’hui anormalement fraîche.

Les statistiques sont là pour nous le rappeler.

Let’s talk about COVID, brain damage & society.

Specifically, what happens when a neurotropic virus repeatedly infects the population, targeting the frontal lobe & almost nobody talks about the consequences?

This thread is for the skeptics.

I’m a neurologist, stay with me 🧵

Covering all of California's water canals with solar panels could generate 13 gigawatts of renewable power and save 63 billion gallons of water per year: https://t.co/Xd1CYbX5DL

Incredible temperature anomalies in the Arctic Circle — especially around Scandinavia — with temps up to 8°C above normal. Ecosystems in this region aren't accustomed to temperatures above 30 °C
At this rate, "Santa" will need sunscreen more than thermals. #ClimateCrisis #Arctic

[Nicolas Fulghum @nicolasfulghum]

With a new all-time record in June (43 TWh), US 🇺🇸 solar power has now reached 192 TWh so far this year ☀️

That easily surpasses the 2021 TOTAL ANNUAL generation of 164 TWh and almost exceeds the 2022 total (205 TWh).

Between this and coal, I know who I would bet on.

[Nicolas Fulghum @nicolasfulghum]

Global electricity generation from solar has been doubling roughly every three years ☀️

In 2024, solar generation grew 29% year-on-year.

This was the fastest growth rate in six years.

[Max Roser @MaxCRoser]

In 2014, half of Greece's electricity was generated by coal.

A decade later, that share has fallen to just 6%.

[Mike Hudema @MikeHudema]

France and Spain are dealing with an extreme heat wave, with temperatures soaring to 40 °C plus in many regions. Climate change makes these heatwave events up to 10x more likely. This is not normal, this is not "summer"

No time to wait. #ActOnClimate

In 2014, France TV weather presenter Evelyne Dhéliat predicted extreme temperatures for a day in August 2050.

Those temperatures became real 25 years earlier.
