Alternative Targets for Carbon Dioxide Stabilization

Explore the significance of alternative carbon dioxide stabilization targets, ranging from 350 ppm to 450 ppm CO2 levels, as advocated by experts like Nicholas Stern, David King, and James Hansen. Discover the urgent need to address these targets to mitigate the risks of global warming and its potentially catastrophic impacts. Gain insights into the importance of staying below critical CO2 concentrations to prevent irreversible climate damage and deglaciation.

  1. Alternative Targets for Carbon Dioxide Stabilization • Nicholas Stern is calling for a target stabilization level of 400-450ppm CO2. • David King (ex-UK Government chief scientists) says anything above 400ppm CO2 carries an unacceptable risk. • Even at 400ppm CO2 it is virtually certain that there will be more than 2 degrees C of warming. This is a critical point that is still not appreciated by most people. • James Hansen (head of the NASA Goddard Institute) is now saying that we must aim for 350ppm CO2 or risk catastrophe. His research indicates that above a particular threshold CO2 concentration the world will completely deglaciate. This threshold appears to be around 425ppm CO2 with a margin for error of +- 75ppm.
