Not so sure 17/1/2014
Uncertainty at the top:
Environmental Protection Agency administrator Gina McCarthy wasn’t able to definitively say whether the world has gotten warmer in Senate testimony.
Alabama Republican Sen. Jeff Sessions asked McCarthy to confirm a statement made by President Obama last year that global temperatures were increasing faster in the last five or ten years than climate scientists had predicted.
McCarthy couldn’t answer the question, saying that she only repeats what the climate scientists tell her.
