I have long thought that the green movement made a huge strategic mistake by going ‘all in’ on global warming as the goad to try to change human behaviour. Sadly, after several rounds of ‘double or quits’, even the smallest events get used against the narrative. It’s time for those who are persuaded of the reality of the Limits to Growth to accept that the political argument about global warming has been lost, for at least another generation, and try and find a more productive way to communicate important truths. Hint: it won’t involve Chris Huhne.
