The White House says the President's views on climate change are "evolving".
So, WHO Radio News asked Iowa Senator Charles Grassley if he believes humans are to blame for climate change. "Of course, man has contributed some to global warming, (but) the amount is still questionable."
But, Senator Charles Grassley says he is NOT a big fan of the Paris Accord on Climate Change. He says the agreement doesn't have the force of an international treaty, but, it still demands more U-S action while letting China continue 'business as usual'. "While they're contributing more to global warming than we are, and, we've already cut back to 1993 levels (of carbon production) anyway."
The Iowa Republican also says India, Indonesia and Brazil aren't being "called on the carpet" by the accord either.
