In the demented political mind of Ted Cruz, denying that climate change is caused by humans is equivalent to Galileo denying that the earth is flat (yep, that's the logic). Or perhaps there is a political motive behind this pronouncement (shocking, I know).
The astute will notice that one of these results is not like the others.
As the WaPo opinion concludes:
The Galileos on climate change are, like Galileo, the scientists. The people pushing back on the science are, like Cruz, those who favor the status quo. Cruz's comments, from start to finish, are simply not correct.
