Great addition.

Every so often I'll see alarmist graphs that show temperature variation over time, back into the ice age or what have you. Of course, the punchline to those graphs is that there is a sharp upwards curve starting right in the 20th century. That always seems disingenuous to me, because there's no way our temperature data from the ice age is anywhere near as granular as our temperature data today, so putting them on the same graph produces nonsense.

I don't think anyone is denying there is warming observed on a broad scale, at least in some form. There are just too many confounding factors to talk about a "scientific consensus" on what might be the cause of observed change.
