Interesting that you have less respect for MF now as I have more than even before.
The quote is brief but if and when we hear the full remarks I suspect they will reveal that he is saying what any right-thinking person would. Specifically, that it is by definition tosh to make any statement linking humans and global warming. We don't have another uninhabited earth in a parallel orbit as a control, ergo any talk of scientific "proof" is wrong by definition.
