The Paris Treaty will do very little to rein in temperature reductions

See We Have A Climate Treaty--But At What Cost? by Bjorn Lomborg in Forbes. Excerpts:

"The Paris Treaty promises to keep temperature rises below 2°C. However, the actual promises made here will do almost nothing to achieve that. It is widely accepted that to keep temperature rises below 2°C, we have to reduce CO₂ emissions by 6,000Gt.

The UNFCCC estimates that if every country makes every single promised Paris Treaty carbon cut between 2016 and 2030 to the fullest extent possible and there is no carbon leakage, CO₂ emissions will be cut by 56 Gt by 2030.

The math is simple: in an implausibly optimistic best-case scenario, Paris leaves 99% of the problem in place."

"Using the best individual and collectively peer-reviewed economic models, the total cost of Paris – through slower GDP growth from higher energy costs – will reach $1-2 trillion every year from 2030."

"Until there is a breakthrough that makes green energy competitive on its own merits, massive carbon cuts are extremely unlikely to happen.

Claims that carbon cuts will be free or even generate economic growth don’t stack up given today’s technology. Every economic model shows real costs. If not, we wouldn’t need the Paris treaty: every nation would stampede to voluntarily cut CO₂ and get rich.

The agreement to spend $100bn on climate aid is a poor way to help the developing world. Their citizens clearly say, this is their lowest policy priority and climate aid provided by handing out solar panels has meager benefits compared with the many better, cheaper ways to help, like investing in immunization, girls’ education, and family planning."
