Urlaub in der Klimakrise.
Keine KI, einfach ein Handyfoto, das ich vorhin am Strand von Lacanau (Frankreich) gemacht habe.
In welchem Klima wird der kleine Junge aufwachsen?

Holiday in the climate emergency.
No that’s not AI or edited, it is a photo I just took with my phone on Lacanau beach in France.
Ash is raining from the sky.
What future will this boy grow up in?
It is in our hands, but time is running out.

Yesterday afternoon 14:09 in Lacanau Océan in France. A pale red sun through smoke tinged everything in Mars style orange.

Hier eine Karte der Lage am Sonntagmorgen und mein Foto von der Fahrt nach Bordeaux am Freitagabend.

The smoke plume of the Gironde wildfire in France extends far out over the sea. Wildfires get increasingly uncontrollable as #globalwarming caused by fossil fuel emissions dries out plant matter faster.
