Climate politics must be as radical as the climate crisis

It’s wrong to think that we can campaign to stop climate change in the same way we might campaign to end a war. All the evidence says we are well past that stage now. That is, even if by some impossible, magical course of events all carbon pollution on Earth was stopped tomorrow, we’d still be in really, really deep trouble. So many greenhouse gases have been pumped into the Earth’s atmosphere that we have rushed far past the safe upper limit — the famous 350 parts per million of CO2, the number that climate action group 350.org took for its name.
