Climate scientist, professor of Physics of the Oceans in Potsdam. Opinions my own.

Stefan Rahmstorf is a German oceanographer and climatologist. Since 2000, he has been a Professor of Physics of the Oceans at Potsdam University. He studied physical oceanography at Bangor University and received his Ph.D. in oceanography from Victoria University of Wellington (1990). His work focuses on the role of ocean currents in climate change. He was one of the lead authors of the IPCC Fourth Assessment Report. .. more

Und vielen anderen Städten!

Am Freitag könnt ihr die vielen Menschen unterstützen, die sich derzeit beim Klimagipfel #COP30 in Belém für unsere Zukunft einsetzen - und auch ein Signal an die Bundesregierung senden. Jede Verzögerung von Klimaschutz kostet viel Geld, Glaubwürdigkeit, Menschenleben, Zukunft.

“Wir in Deutschland importieren fossile Brennstoffe für mehr als 80 Milliarden Euro pro Jahr. Das ist buchstäblich verbranntes Geld.

Sogar in Deutschland verkaufen sich Wärmepumpen, allen Kampagnen, aller Desinformation zum Trotz, längst besser als Gasheizungen.”

Bei der Klimakonferenz im brasilianischen Belém gibt es Grund zur Hoffnung. Das zeigt sich schon an der Autokolonne, in der Brasiliens Präsident Lula beim Gipfeltreffen vorfuhr.

Taifune sind - genau wie Hurrikane - tropische Wirbelstürme (sie heißen nur im Pazifik anders). Sie bekommen durch die globale Erwärmung immer mehr Zerstörungskraft. www.tagesschau.de/ausland/asie...
Nächster Taifun trifft Philippinen: Fast eine Million Menschen evakuiert
Erst vor wenigen Tagen riss der verheerende Taifun "Kalmaegi" Hunderte Menschen in den Tod, jetzt zieht ein neuer Tropensturm über die Philippinen. Fast eine Million Menschen verlassen ihre Häuser.

One of these quotes is real: Musk actually made this sick statement.

The other one most likely is not: Though you may have seen it before because it is very relevant now, it appears to be misattributed to Hannah Arendt.

1/5

“The death of human empathy is one of the earliest and clearest signs of a culture descending into barbarism.”

A good quote but I was informed it’s not from Hannah Arendt, so I deleted my post which included that wrong attribution.

The quote is literally in text form in the post. It often is the case that the post itself describes what is then also seen in an image, and stating that there is a photo of Hannah is definitely not needed to understand the post. You may not have empathy with my work load and very limited time.

Danke für den Hinweis!

Indeed this is an excellent nuanced and optimistic response to Bill Gates by @hausfath.bsky.social !
(Though admittedly less entertaining than @climateadam.bsky.social.)
It’s a good example of how to debate constructively about solving the #climatecrisis.

True, but hopefully people are smart enough to see where the steep slope is. It is happening *now*!

Today the 2025 State of the Cryosphere report was published by over 50 leading cryosphere scientists.

What did Bill Gates actually write? What is right and what is bizarre about it? And how was it then distorted by the media?

In fact it is already happening. The tropical coral reefs are past their tipping point, mass bleaching is widespread. 😢

Guterres is right.
Even a temporary overshoot could unleash far greater destruction and costs for every nation. It could push ecosystems past catastrophic and irreversible tipping points.
