Yesterday I saw An Inconvenient Truth. My first impressions of the movie were about the slide show. I gave about a million PowerPoint presentations in my college career so I suppose I had an expectation that the slide show would be somewhat similar to that. Namely, boring, with the bullet points and the remote control clicker and all that. But instead it was this beautiful multimedia extravaganza, a seamless integration of facts and video and really effective charts and graphs. The one graph about the correlation between CO2 levels and temperature, where Al Gore climbed onto the stepping stool, that was genius.

And the message of the movie, of course, is a very serious one. I had no idea that Al Gore was so dedicated to studying this subject. He's a very credible and authoritative speaker on global warming. Out of all the things that I've seen or read on global warming, this movie has been most convincing to me of the seriousness of the issue. This problem is on such a huge scale with such great ramifications for the entire planet. But it just seems that fixing it is going to be extremely difficult, if not impossible. How do you get the entire world to change? Particularly when some U.S. leaders are still waffling on the issue of whether global warming is happening at all. I'm worried. I'm very worried.
