Quite often you'll read deniers claiming that the earth is warming by magic, or supernatural forces. No denier will ever use the words "magic" or "supernatural". They'll pick a euphemism, like "Little Ice Age" - though how an ice age caused warming I've yet to see anyone explain.

Occasionally there'll be a vague explanation for the unnatural state, usually something to do with the sun - but with little enthusiasm. (The sun may have played a minor role during the Little Ice Age, recent research points to the cause of it being heightened volcanic activity, which is thought to have driven changes in the ocean which caused more cooling. See papers below.) And when one asks, well what about the decline in solar forcing recently - why hasn't it cooled down? You'll be lucky to get a response.
