The imperative for carbon reduction is urgent — In order to limit the global mean temperature increase over historical norms to about 2 degrees Celsius (the temperature at which there is a high probability of catastrophic impacts), global emissions need to be reduced approximately 40 - 70 % below 2010 levels by 2050, with CO2
emissions peaking soon (IPCC, 2014).
The details of this pathway are that: 1) global
emissions peak soon (about 2020) and decline by 2050 to 50 percent below 1990 levels; and 2) Northern emissions simultaneously decline to 80 percent below 1990 levels.
