#PPM
CO2 during COP1 was 360 ppm.

CO2 during COP31 is 427 ppm.

Any questions?

I was born in 1941, when CO2 levels were about 310 ppm:

Und wenn man messen würde: nagelneue Schule, Inbetriebnahme 2025: man fände Werte in den Klassenzimmern jenseits der 2.000 ppm
Ich fasse das alles nicht, wo sind all die Filter hin, die angeschafft wurden?
Wie krass kann Verdrängung sein, solche Werte in den Keller zu stellen!?
Eigentlich frühstücke ich deswegen nie.
Ich freue mich über jedes Hotel, dass diese noch im Einsatz hat und Angestellte mit Plastikscheiben schützt.

The last two years have seen relatively modest increases in atmospheric CO2, expected to increase 2.2 parts per million (ppm) in 2026 after increasing 2.1 ppm in 2025.

These increases are lower than the record increase of 3.7 ppm in 2024 and the average increase of 2.5 ppm in the last decade.

Atmospheric CO₂ concentration increased from ~278 ppm in 1750 to 425.6 ppm in 2025, and a predicted 427.7 in 2026 (54% above pre-industrial).

Still, we do need carbon removal eventually.

Current CO2 levels of ± 426 ppm need to go back to 280 ppm (pre-industrial level).

First emissions to zero, and then large scale carbon removal.

Evolution de la concentration de CO2 dans l'atmosphère :

▪️Ere préindustrielle : 280 ppm
▪️COP 3 à Kyoto en 1997 : 365 ppm
▪️COP 21 à Paris en 2015 : 402 ppm
▪️COP 31 à Antalya en 2026 : 429 ppm

Les solutions : sobriété et efficacité énergétiques, grand remplacement des fossiles par les renouvelables.

Schlechte Luft soll keine Schule machen! 🚫

Es mag "normal" sein, dass Schülerinnen & Schüler wie auch Lehrkräfte in schlechter Luft lernen & arbeiten müssen.

Wir wollen das ändern!

5000 ppm recorded inside cramped urban tenements - the increase in disease spread and mental sluggishness was pretty clear by then.

Als 1992 Klimarahmenkonvention unterzeichnet wurde, lag CO₂-Konzentration bei 356,42 ppm. 2025 waren es laut WMO 426,8 ppm. Seit 1750, Beginn der ind. Revolution, ist Konzentration um 53 % gestiegen.
Kurz & knapp: Aufgebraucht. 👍

Im Detail: CO₂-Konzentration (ppm) misst krit. Schwellen. Schwelle zur Stabilisierung bei 1,5°C liegt bei 430 ppm, lag 2025 bei 426 ppm, steigt um 2,5-3 ppm/Jahr.

CO2 at 446 ppm and rising and they do what?

Ich wurde bei 329 ppm geboren. Heute liegen wir bei 429 ppm. Das ist schon heftig wie sehr der Mensch hier beiträgt. Abholzung von Regenwald für Tierhaltung wirkt doppelt. Methanlecks und Russland das sich hier an gar nix hält. Die USA die gerade Erbeuerbare Energien ganz abdrehen wollen usw.

Also airplanes and airports. With airplanes, CO2 readings are the highest I've ever measured, 1500 ppm. Passengers are sharing each other's lung air. It's airborne snot.

right but they’re not even complaining about that, they’re complaining about, like. i don’t even know. the presence of 1 ppm of dario amodei in the supply chain of a video game they liked?

Atmospheric CO2 ppm is expected to rise this year by 2.2 ppm and is predicted to rise next year by 3.5 ppm next year.

This is the figure that really matters. Everything else is window dressing.

We are going the wrong way, quickly.

Meanwhile atmospheric CO2 is set to increase by 3.51 ppm - the largest single rise ever predicted by the Met Office.

IPCC and the COP process is not fit for purpose.
IPCC Chair Jim Skea addressed Türkiye's Climate Projection Launch Event at COP31 today, focusing his remarks on what is new in #IPCC’s Seventh Assessment Report and highlighting links between IPCC activities and the Turkish climate projections.
