It doesn’t matter if his literal words were an error in repeating the talking point or if he got the talking point correct. The talking point itself is wrong. The inference we are supposed to make from the talking point, that the warming is due to solar forcing alone, is wrong.
Whether he truly thinks Mars is the same temp as Earth or that they both experienced the same temperature trend the specific words are irrelevant. What he wants everyone to take from the point is that coal, oil, and every other fossil fuel can be burned without consequence.
That is the point that needs to be addressed.
