Genau… (und ja ich beziehe mich auch auf Berlin/ Brandenburg)

Ist in meinem Post aber nur der Dezember dargestellt, der wirklich krass trocken war.

Aber tatsächlich war das gesamte Jahr 2025 auch unterdurchschnittlich nass und überdurchschnittlich warm, aber jeweils nur leicht (im Mittel, regional natürlich teils sehr unterschiedlich)

Ich finde es immer interessant, wie weit die Wahrnehmung in der Bevölkerung und die Realität auseinander liegen. Die meisten werden sagen, was 2025 für ein nasses, regnerisches Jahr war 😳

Monatsrückblick 🌧🌡️ Dezember 2025:

links:
Niederschlagsmenge in Prozent zum langjährigen Mittelwert
rechts:
Abweichung der Temperatur vom langjährigen Mittel.

👉 Im ⌀ 3,5°C zu warm. Und überall (!) viel zu trocken. 😐

Karte von Deutschland mit den Niedeerschlagsmengen in Prozent zum langjährigen Mittelwert. Stark unterdurchschnittliche Werte sind orange dargestellt, ganz Deutschland ist orange. Es war überall viel zu trocken.

Karte von Deutschland mit Abweichung der Durchschnittstemperatur von Dezember zum langjährigen Mittelwert. Fast ganz D war deutlich zu warm, nur Südost und Süd-Bayern waren nah dran am "Normalwert".

Only 19% of peatlands are in protected areas — and many still face drainage and degradation.
True protection needs laws, enforcement, and inclusion of Indigenous Peoples, local communities, and women in management.

Experimental evidence that students are more likely to contest grades when they are delivered by an evaluator with a female-sounding name.

"These findings suggest that women in evaluative positions face disproportionate resistance when delivering negative assessments."

Thousand of bulldozers on the way to flatten over 5 million acres of forest in West Papua and this is just one ship
Such is the rush that even the Indonesia army has been brought in to speed up the deforestation
A shameful day for Indonesia and the world

I keep seeing articles about 'rebuilding trust in science'

They all focus on changing how science is carried out, but mistrust in science isn't the result of what scientists do - it has been manufactured by the science denialism industry

Science isn't the problem, the forces of anti-science are
