The Earth is millions of years old. We’ve been keeping records on the Earth’s temperature for about 100 years. We don’t do a very good job of predicting what the weather will be like next week, much less years or decades from now. To look at the evidence that we have collected and say that the Earth is headed past some “point of no return” would be like watching a human hold their breath for 20 seconds and declaring that they will never breathe again. I’m sure others will come along after me and tell you that I’m naive or that I’m rejecting the scientific evidence, but I’m just not convinced. Do yourself a favor, read Al Gore’s book and then read Glen Beck’s “Inconvenient Book,” then make up your own mind.
