China’s CO2 emissions have now been flat or falling for 18 months, starting in March 2024.
This trend continued in the third quarter of 2025, when emissions were unchanged year-on-year.
If this trend starts to move into sustained carbon emissions reduction it would be hugely significant.
The land and ocean CO₂ sink are 25% and 7% smaller, respectively, than they would have been without the effects of climate change and variability, on average for the 2015-2024 period.
Combined, this is equivalent to the total sink (land and ocean) being nearly 20% smaller than otherwise.

Fossil CO2 emissions continue to rise in 2025 while the terrestrial carbon sink recovers to pre-El Niño strength.
The key findings are covered in two reports this year:

Tout sur l’état du développement du solaire photovoltaïque en France fin 2024 :
* 6 000 MW installés en 2024 💪
* Un tiers des nouvelles installations est « au sol »
* Coût en toiture > 2,7 fois au sol (710 le kW)
* Coût des modules : 25% du total d’une installation

Trump claimed at the UN: “They [China] build them, but they have very few wind farms. So why is it that they build them and they send them all over the world, but they barely use them?”
Answer is: they actually do. China has more wind power than any other country.

The ocean has shielded us from the worst of the climate crisis: absorbing over 90% of the excess heat and storing vast amounts of carbon.
Because 90% of the ocean is the deep sea, protecting the deep is essential for a healthier, more resilient planet.

Les chiffres noirs indiquent les estimations de biomasse absolue, les chiffres gris indiquent la fraction de la biomasse totale estimée des mammifères En haut : la biomasse totale des humains et des mammifères domestiques (bovins, buffles, porcs et autres). En bas : la biomasse totale des mammifères marins sauvages, ainsi qu’une estimation de la biomasse totale des mammifères terrestres sauvages.
Quelle est la biomasse totale de tous les mammifères sur Terre et son évolution depuis 150 ans ?
Si celle des océans et des animaux sauvages a sensiblement baissée, la biomasse correspondant aux humains et au bétail a littéralement explosé (95% de la biomasse totale)
