I'm aware of most of that (and thanks for the link.)
By bringing up the evidence from the past I mean to remind people that the earth's climate at different times has been both significantly warmer and colder than it is today, for a variety of reasons, all without any input from humans.
With that in mind, it is reasonable to postulate that in the future the earth's climate is also likely at different times to be both significantly warmer and colder than it is today, for a variety of reasons, regardless of the effects of human input.
Based on that information, I think that it makes more sense to invest our efforts into improving our ability as a species to adapt to climate change than to control it. That does not absolve us from any responsibility to use our resources more efficiently and effectively, but it can to a certain extent protect the gullible from those who would sell a product or philosophy based upon promised effects that have little (if anything) to do with the (multiple) identified causes of past climate change.
