An open letter addressed to world leaders ahead of the Paris climate conference in December. The letter is framed in moral language and calls for world leaders to make serious commitments to avoiding climate catastrophe, and for citizens to hold them responsible. The letter is being hosted at the Global Climate Change Week website. Our goal is to collect a significant number of signatures from academics around the world and to place the letter, with several translations, in The Guardian (or a similarly high profile outlet). Ideally, we hope to get as many notable academics as we can to sign the letter early. The letter just went live and I invite you to sign the letter (if you approve) and pass it along to colleagues.
