Indeed, the science is complex, and there are all sorts of legitimate reasons to challenge the validity of the models. As for “hubris” regarding mankind’s perceived ability to either effect or prevent global-scale catastrophe, you really can’t blame anyone for being a tad circumspect in a post-Chernobyl age.
On the other hand, citing Winter cold and snowfalls as a repudiation of Global Warming simply demonstrates appalling ignorance of how shit actually works, and/or a deep commitment to the new Conservative strategy of undermining both Science and Government as authorities, in order to rehabilitate “God” and “Common Sense”—i.e., the Warm, Comforting Woobies of uneducated nitwits.
Sarah Palin, who is a devious, self-serving fuckstick whose own hubris could use a 100,000-mile checkup, might as well be Tweeting a message to the Wright Brothers:
Machines 2 heavy 2 ever fly. What’s next—use hot water 2 move a train? Science in 4 big s’prize if try to imitate glory of God’s Design.
