The Paris COP21 draft agreement about which there will be endless disagreement is here. Read it if you have the stomach for it. After a preliminary scan I didn't bother although a reference to holding future global temperature increases to 1.5 °C is interesting.
Emphasizing with serious concern the urgent need to address the significant gap between the aggregate effect of Parties’ mitigation pledges in terms of global annual emissions of greenhouse gases by 2020 and aggregate emission pathways consistent with holding the increase in the global average temperature to well below 2 °C above preindustrial levels and pursuing efforts to limit the temperature increase to 1.5 °C.
You know what? I don't think they expect to see a dramatic and possibly not even a significant global temperature increase at all. They know the science is bollocks.
