Have you looked at the projects suggested in Science Buddies? There are several in the Weather and Atmosphere projects that you could connect to global warming:

Suppose you decide to do the Weather and Climate in Your Neighborhood project. (I'm not sure whether you've done science fair projects before or not; another one along the same lines would be the Dry Spells, Wet Spells project.) Global warming predicts that many areas will have warmer temperatures. You can use Internet databases to look at the average, maximum, and minimum temperatures for each season over a span of ten or more years. You can then ask whether the temperature in your area is increasing, as you would expect it to for global warming. In addition to the websites listed on the Science Buddies project page, the NOAA (
http://www.noaa.gov) also keeps track of air and ocean temperatures. If you're interested in something like that and let me know what state you're in, I can try to find the NOAA page for you.
One thing to be careful of in an experiment like this (seeing if actual temperatures match the global warming model) is that some areas are actually expected to decrease in temperature because of global warming. It sounds contradictory, but it has to do with how air and ocean currents distribute heat throughout the world.
Good luck with your project!
