The Talking Dog has an excellent interview with Adam Stein, Vice President for Marketing of Terra Pass. Mr. Stein is obviously on one side of the climate change "debate" but his thoughts are certainly well reasoned. Especially this one.
But a key point is that there is no scientific debate -- there is not a single peer reviewed scientific journal article that disputes the reality of man-made climate change at this point...CO2 records go back 600,000 years, and there is now no alternative explanation-- in short, the "debate" is over. The only question is just how long it takes for most people to understand, and act on this.
Despite what you may hear in certain circles, the debate on man dramatically affecting the world-wide temperature is indeed over. It is now only a matter of discussing what are the potential consequences and, if needed, what are the potential solutions.
