We collectively need to
demand that there is no acceptable
response to climate change other than strong emission reductions, ensuring that atmospheric concentrations of CO2 are returned to 350ppm levels, global temperature rise is kept (at the maximum) 2 °C and, even better, 1.5 °C — to do that, as was emphasized on numerous
occasions, we need a F.A.B. climate deal: Fair, Ambitious, and (perhaps most importantly) Binding.
