The facts of climate change have entered the public consciousness to an unprecedented degree over the past couple of years. But to date there hasn’t been a strong, coherent campaign around which masses could organise. Effective campaigns need clear targets and, ideally, clear deadlines.

I’m hoping that that is what the recently announced 100 Months can offer. Introduced by Andrew Simms, writing in the Guardian, the campaign is based on the idea that 100 months is a very good bet for how long we have until the cascade effects of climate change take us past the final tipping point.

It suggests a series of integrated policies, promises monthly actions for its supporters, and hints that a powerful, deadline-driven coalition may yet emerge. We can only hope (and click, act, lobby, and all the rest).
