I can’t figure out why Peter Sinclair says, at 10:16, that “The changes are local, not global, as climate deniers would have you believe.”

Wouldn’t climate deniers have you believe just the opposite, that the changes are local, not global?

Are the scientists not saying that the changes are global, not local?

Did Peter Sinclair mean to say that “The changes are global, not local, as climate deniers would have you believe.”

I am rather confused by this apparent contradiction. (I am not engaging in climate denial. I am just confused by what I expected Peter Sinclair to say at that point and what it appears that he said.)
