Over at AccuWeather, Joe Bastardi questions Al (Darth) Gore's credibility as a climate commentator. It's a great read and this note about the science of climatology from the comments is spot on:
leave the climatology to professionals who know what they're doing
That sounds like an oxymoron.
Predictive climatology is in it's infancy, and no one has demonstrated skill better than a random number generator to date. There are too many random chaotic factors (volcanic eruptions, solar activity, clouds, etc.) for there to be much likelihood of success in our lifetimes.
Several climatologists have demonstrated limited skill at politics and manipulating numbers to fit a curve however.
