The obvious question these "scientists" were too stupid to ask is: "If CO2 ENDED the "Little Ice Age", what CAUSED it in the first place?" And then "Do you possibly think that whatever caused it, just might have simply STOPPED causing it"?
I think it's simpler than that. They sound like teenagers trying to write the coolest sounding fiction. The more cooler they think their story is the harder they thump their chests.
