Sensible risk management today dictates that atmospheric carbon should be stabilized at 350 parts per million of CO2 equivalent, not the current pathway of 450 500ppm CO2e. This requires emission reductions of 45 50 in industrialized countries by 2020, and almost complete de carbonization by 2050, not the levels of 15 25 by 2020 and 60 80 by 2050 that are now on the table.
