Duke University just released an analysis of the impact that ACES will have on global temperature, factoring in the impact that US leadership will have on the rest of the world. As many recognize, the only way to get serious global efforts to cut emissions moving is for the US to make clear its own commitment.
The Duke study concludes that ACES can help drive a global policy that would stabilize carbon dioxide concentrations below 450 parts per million and limit global temperatures increases to less than 2 degrees above 1990 levels.
What will that do as far as global warming impacts go? Here's a synopsis of the escalating impacts of global warming, based on IPCC reports. You can see for yourself what global warming effects the ACES bill will help us avoid:
The bullets ACES will help us dodge: global GDP losses of up to 5%; extinction of 40% or more of the world's species; decline of global food production; and so on.
Amidst all the posts regarding the economic benefits of the ACES bill, its worth remembering that it will put us on track to avoid the worst effects of global warming.
