Vielen ist nicht mehr bewusst, dass ≥ 35°C selbst im Oberrheingraben früher selten waren und nur alle paar Jahre mal 1 bis 2 Tage dabei waren. Nach 2003 und 2015 stellt der Sommer 2026 nun alles in den Schatten. /FR

Foto al eclipse hecha hoy con mi Xiaomi 17 Ultra y un filtro protector de la lente. ¿Notáis algo raro?
Pues sí, la luna era la otra. Ha detectado una esfera brillante en el cielo, se ha puesto en modo "superluna", y directamente se ha inventado toda la superficie – at Madrid, Spain

Relevant xkcd for those of you within a drivable distance to the total eclipse.
A 91% eclipse does not mean it’s 91% as cool as a total eclipse.
If you can’t make it to totality, a partial eclipse is still worth seeing… but a total eclipse is more than worth the extra effort.

Somewhere between the indestructible American ice cream, rubbery watermelons, and uncrushable strawberries, I believe you'll find a whole new appreciation for EU food safety standards.

If you still don't think climate change is making these fires worse, feel free to comment. It'll also be the last comment you ever make on one of my posts.

Canada is on fire.
Europe is on fire.
The Amazon is on fire.
Cities are breaking heat records.
Rivers are drying up.
Other countries are drowning in floods.
Storms are getting stronger.
Seasons don’t feel like seasons anymore.
And somehow…
climate change is still a debate.
One single photo, only 13 seconds, but 12 satellites on it. This fucking space junk is ruining Milky way photography.

The largest solar radiation storm in over 20 years is now underway.
An S4 severe solar radiation storm is in progress and the last time this level was observed was October 2003.
Potential impacts are expected to be largely confined to space launches, aviation, and satellite operations.

Latest NASA CME model: CME may be FASTER than originally anticipated. Impact is slated for Jan 20 around 1 UT--it's a very fast CME and could deliver strong geomagnetic storming Monday night with auroras visible across mid-latitudes. We'll see what happens over the next 24 hr!
