Question for the GW skeptics.. How many of you are scientists?

Yes I am a "scientist-in-training" if you can accept that as my college major, Biology. Does that make me an expert in climate, no. Do I have to be an expert in climate to simply acknowledge that the IPCC has not proved 100% that we're the primary cause of global warming, no. The beauty of the written doents published by the IPCC is so that an ordinary person can read them and make a decision based on that information. I've read the doents and no where does it say humans are the primary cause of climate change. They may think we are but they can't prove that we have. You may call me a "denier" but I am simply waiting for proof like everyone else.
