Beyond Inorganic C: Soil Organic C as a Key Pathway for Carbon Sequestration in Enhanced Weathering
Enhanced weathering involves spreading crushed silicates on soils. Upon weathering of the applied silicates, CO2 is captured via two pathways: pedogenic carbonate formation and leaching of bicarbonat....

How much carbon budget do we have left if we want to stay below 1.5˚C?
Just 2 more years at current rates. It is essentially impossible to avoid global temperature rise exceeding 1.5˚C.

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.

A paper in Nature suggests a quarter of heatwave events from 2000-23 would have been near impossible without anthropogenic climate change. The paper also indicates that major carbon emitters are responsible for around 50% of the increase in intensity of these events. ⚒️ 🧪
Systematic attribution of heatwaves to the emissions of carbon majors - Nature
Climate change made 213 historical heatwaves reported over 2000–2023 more likely and more intense, to which each of the 180 carbon majors (fossil fuel and cement producers) substantially contributed.

Bomen planten is geen magische klimaatoplossing. De impact is veel beperkter dan vaak wordt aangenomen.
- Minder land beschikbaar dan gedacht.
- CO₂ opslag veel kleiner dan uitstoot.
