Speaking on climate, Kevin Anderson, professor of energy and climate change at the Universities of Manchester, Uppsala and Bergen, said: “The choice is between deep, rapid and fair decarbonisation of modern society, and an organised-ish technical and social revolution; or ongoing rhetoric and delay as temperatures [rise]. And then we’ll have a revolutionary style change that will be both chaotic and violent.”

On nature, Nathalie Seddon, professor of biodiversity at the University of Oxford, said: “We are facing a national emergency not only because the climate is changing, but because the living systems that protect the climate are breaking down.”

She added: “This isn’t about choosing between the economy and the environment. It’s about recognising that the economy is embedded within the environment, and that the health of the nation depends on the living systems that sustain us.”

And yet, despite this, we still get “Drill, baby, drill!” in our budget.
