You know that whole shouting match about global warming? I know it seems like such a noisy mess that it's easy to tune out. But here's a thought for you: while we debate whether humans can really change the climate or not, we are at the same time running the experiment. The kicker is, no matter what the outcome of the experiment, we're in the test tube! So it seems clear that we'd better get to the bottom of the controversy as quick as possible. But how do you know which side to believe?
How does that logic work for you?
