The story title is B S, even though man made global climate change is real & will have very negative efffects on the world population in the future.  That is because the damage is already done & even if all the industrialized nations stopped releasing greenhouse gases tomorrrow, it will take many generations to resolve itself regardless of the climate agreement.  Better for the US to focus on improving electric cars & SAFE nuclear power electrical generation than some climate agreement where countries like Russia & China would secretly violate the terms anyway.  Get the electric cars perfected & affordable & other countries will follow US's business lead in providing alternative fossil fuel base transportation (except air travel).  In Hawaii if we want to be energy self sufficent & stop being a slave to fossil fuel power generation that the Oahu rail project better be cancelled because that beast will use so much electricity, a new fossil fuel electric generator must be built on Oahu.
