It’s the last chance for the climate. Of course, this is said before every annual COP, but for COP26, which starts this weekend in Glasgow, it really is the case. Scientists are clear that to meet the 1.5-degree goal set by the Paris Agreement, global emissions of carbon need to be cut by half by the end of this decade. That won’t happen if COP26 fails, momentum is lost and climate targets are watered down.

It has become something of a cliché, in advance of each annual climate summit, to say that it represents the “last chance to save the climate” or somesuch.

For COP26 this is actually true in a very specific sense. The meeting in Glasgow really is the last chance for the world to embark on the drastic cuts in emissions required to achieve the Paris goal of keeping global temperatures from rising by more than 1.5 degrees Celsius.

The scientific consensus that humans are altering the climate has reached 99.9%, according to a paper of which I was lead author, published in the journal Environmental Research Letters.

Here’s Cornell University’s news story, and coverage from the Guardian.

So what might be a COP26 climate emergency target that we actually could meet? My suggestion is extremely simple: we set a date for the worldwide exit from fossil fuels, a sort of independence day from carbon. Like all ideas that eventually become mainstream, at first sight this looks preposterous. You mean, we actually have to stop burning oil? No more petrol? No more LNG tankers plying the world’s oceans? No more giant coal machines scraping up carboniferous forests from underneath medieval villages in eastern Germany? Yes, that’s exactly what I mean.
