The Paris Climate Agreement Won't Change the Climate

For Prager U, Bjørn Lomborg explains the Paris climate agreement.

For an example, when the committee asked the head of the US Environmental agency:  
Exactly how much will this treaty reduce global temperatures? 
she could not, or would not say.

As Bjørn says:
The agreement will cost a fortune, but do little to reduce global warming. 
The Paris Climate Agreement will cost at least $1 trillion per year, and climate activists say it will save the planet. The truth? It won't do anything for the planet, but it will make everyone poorer--except politicians and environmentalists. Bjørn Lomborg explains.
