I am guessing that few are really climate experts if our ability to predict next seasons climate (never mind tomorrow's weather) is any indication. We are really limited to studying what evidence we can gather from the distance past over the eons, and models. The great thing about predicting long-term trends is that you will be dead before you can be proven wrong (or right). All kidding aside, I would love to see offensive posts censored rather than topics restricted, but I guess its like driving with cell phones. Instead of ticketting dangerous driving, everyone gets punished. By the way, cell phone use is not restricted while driving in Indiana, but I don't do it because I can't drive safetly while talking on my cell phone.
