Climate Catastrophe by John Stossel
People argue about whether the "consensus" of scientists is that we face disaster because of global warming. Instead of debating whether man's greenhouse gasses will raise temperatures, we should argue about how we gauge disasters.
If you take most environmentalists and climate scientists at their word, the Earth heated up about 1.4 degrees Fahrenheit over the past century, not much more than it heated up the century before that. Warming may increase, but no one can be certain of that.
