Wim Carton and Andreas Malm emphasize dismantling fossil capital over geoengineering or carbon removal.
They warn that crossing climate tipping points between 1.5°C and 2°C could cause irreversible ecosystem changes.
Adaptation becomes much harder after these tipping points are crossed.
The collapse of the Atlantic Meridional Overturning Circulation poses a significant risk for Britain, with a tipping point between 1.4°C and 2.2°C.
