Paris pledges would prevent a 2°C path
According to the UN report on Paris pledges, at best they will use up 723 out of a 1000 Gt CO2 budget required for a 66% chance to stay below 2°C. At 40 Gt a year, this runs out in 7 years. The red line stretches this to 14 years with a crash abatement program. MIT says that if the pledges work as expected (not perfectly), the red line would need to hit zero by 2040.
Climate Action NOW! is a Toronto-based volunteer group
We are dedicated to awakening Canada's citizens and leaders to the urgent need for a scientifically grounded and equitable climate plan that reflects Canada's fair share of the globe's remaining burnable carbon.
We call on all Canadian governments to fulfill our promise made, in Paris, to keep the global temperature increase under 2 degrees and to pursue efforts to limit the temperature increase to 1.5 degrees C.
