I really don't think the point is to raise awareness about global warming. I mean everyone knows that we are changing the climate.
I think the point is to make people think about their own energy consumption and how it affects the world. I mean when a lot of people complain about global warming, I think they are somewhat disconnected from the whole thing (like they don't realize that it is their own consumption that contributes to it).
It seems to me though that it is not very effective way to do this. Most people who do it will probably go back to their 7-planet lifestyles right after the hour. The people who will really try to change their lifestyles for the better, well they would have probably done it without an "earth hour". Still though, I think the people doing it mostly do have good intentions and are certainly not doing it to "inflate their egos".
oh p.s.
