The ‘flickering’ of Earth systems is warning us: act now, or see our already degraded paradise lost | George Monbiot

When Rishi Sunak granted 27 new North Sea licences this week, he wasn’t thinking about the survival of the living worldCan you see it yet? The Earth systems horizon – the point at which our planetary systems tip into a new equilibrium, hostile to most lifeforms? I think we can.

But even this is a euphemism.
