Climate change is upon us, yet we are far, far away from any solution.  That’s because there are two pieces missing from the jigsaw puzzle: a global agreement on how to share out the adjustment to a low-carbon world, and national reduction plans which have citizen buy-in.  This talk focuses on the first lacuna: the lack of a global agreement and argues that we need a broad deal, between the developed and developing world, which includes more than reductions in emissions and the transfer of money–it needs to include access to the markets of developed countries.
