The delegates, all of whom are ignorant about basic science and climatology are being told that there may be no way to prevent the planet's temperature from rising, given the current level of greenhouse gases already in the atmosphere and the projected rate of emissions expected to continue before any new deal is carried out. While a breach of the 3.6 degree threshold appears inevitable, scientists say the climate negotiators should not give up on their efforts to cut emissions. At stake now, they say, is the difference between a newly unpleasant world and an uninhabitable one.
