Still, I would agree that anyone jumping in with both feet onto the "mankind is responsible" bandwagon has to concede that the globe has warmed and gone frigid in dramatic fashion all on its own many times through millennia without humans helping it . . . . . and we have to understand why that is as well.

You really ought to watch Gore's film, as he goes into great depth on that very subject, showing a graph of the average temperature of the earth going back hundreds of thousands of years, including multiple ice ages. He then overlays another graph of CO2 levels in the atmosphere during that same time-frame, and it's impossible to argue that there's a direct correlation between CO2 and temperature. He then shows another graph that projects near-future CO2 levels to be far and away higher than anything seen before over thousands of years.
As was noted above, the myth that global climate change is a "controversial theory" is one put forward by the media. He notes in his film that of 900+ articles about global warming published in peer-reviewed scientific journals,
not one contested the fact that it was real and worsened by human activity. At the same time, a sampling of an equal number of media stories showed something like 58% of them referring to global climate change having much doubt within the scientific community.
