Frank, although it's not the most informative thing in the world, I for one would have trouble getting much out of 40 seconds. And since when is Gore's book "peer reviewed" in the traditional sense? Was that tongue-in-cheek? I also doubt Gore said water vapor is the main cause of global warming. I believe he acknowledges water vapor as a significant amplifying feedback (discussed
here), as most climatologists do. Big difference.
Ollie, I think that's a perception problem. You can't get a picture of a global climate trend by looking at seasonal weather events, or listening to media accounts of regional record temperatures. The averages are what count, and the ratio of record highs to record lows over time is also telling. And it could be a mere 31 degrees and you'd still get heavy snow if regional moisture availability is high.
Those blaming practically everything on global warming (especially at this stage) seem to be in the minority, but that doesn't stop some from pointing to them as a reason to dismiss the issue. Realists know we're looking at an interaction of natural factors and the growing radiative imbalance of the planet. The science examines the influence on things like atmospheric circulation, pressure gradients, and precipitation patterns, and on the incidence, duration, and intensity of events. It doesn't tend to say event X was "caused" by global warming. Heck, from what I've seen even Al Gore generally avoids such language. Not that Gore is the be-all and end-all of AGW, as much as those obsessed with political whipping boys like to think so.
