On May 9, for the first time ever, the world’s longest-running, high-precision instrument to record atmospheric CO2 hit the 400ppm level. 275ppm was the norm before the industrial revolution. The concentration has not risen in a linear way, but exponentially. To stand a reasonable chance of not wrecking the climate and the ecosystems we depend on, that exponentially rising curve has to go down again before reaching 450 ppm, by 2050 (stabilisation below 400 ppm would be required to give a relatively high certainty) Scientists and the International Energy Agency calculated that in order to do that, most fossil fuels needs to stay below the ground. But they don’t say how we could get to that scenario, in a world flooded with cries such as ‘drill, baby, drill!’ 350.org co-founder Bill McKibben said, “The only question now is whether the relentless rise in carbon can be matched by a relentless rise in the activism necessary to stop it.”
