7 years window for stablising the climate

Here’s Rajendra K. Pachauri’s [Chairman of the Intergovernmental Panel on Climate Change (IPCC) ] panic-inducing assertion: We have a window of seven years to stabilize CO2 at today’s levels if we are to limit our global mean temperature increase to around 2.40C. A world this hot would be a very unpleasant place to be. Pachauri lays out unequivocal” evidence of climate change, and describes how extreme precipitation events, heat waves and other natural catastrophes will become more frequent, endangering vast swaths of humanity. We stand to lose 20-30% of species if warming exceeds 1.5 to 2.5 0C. Pachauri also notes this “scary prospect”: the rapid loss of ice sheets on polar land, leading to sea level rises of several meters, and the flight of large populations in response.
