Perhaps one thing that needs to be done is to stop calling it global warming and call it what it actually is: Climate Change. And then spend the rest of your life researching historical climate data that will ultimately show that climate change has been and always will be an ongoing process, before man existed and most likely after man ceases to exist. Using the term "global warming" makes it too easy for folks to blow off the whole idea when they don't see a big change in the thermometer. However, if you look at the ice cap situation it should be pretty obvious that there is a major change underway. Would that change have taken place if man didn't exist, or is it a product of man screwing up the atmosphere? Don't know, and don't see any foolproof way to figure it out either. The best we can do is look at the scientific models and realize that reducing carbon and ozone emissions may or may not help, but surely won't hurt. And of course, man being the manipulative and greedy creature he is, there will be plenty of folks who profit from this fear mongering. That also has been the way of the world, and will most likely not change until man ceases to exist.
