He's absolutely a danger to any efforts against climate change, but this is just one of many examples of him not even able to parse a question or stay on topic. The last I saw was a specific question on Google and Trump went on about Virginia voter rolls, and the host had to remind him the question was about Google. Even if his policies made sense, would you want someone like that in a position of power where he's in charge of decisions? Just getting a breakfast order from him must be painful.
Someone like Sacha Baron Cohen or Tom Green should make a movie about searching the 30k immigrants that Trump claims have been "dropped" into Springfield.
