Stop. There is no meaningful argument: the current, epochally high rate of CO2 release is driving current climate change. Wow, I'm glad you have all the answers. I did not intend to fire off a political debate, I am just truly curious. I think that immediately accepting that it's all because of us is disingenuous to the scientific method. Whether or not the majority of climate change is due to CO2 released by human activity (which I'm still yet to be convinced of), my question was whether the small-scale changes being championed (CFLs, hybrids on an individual scale, living less comfortably (less A/C, bottled water, etc.), and so on) are really going to make a difference in regards to the climate. That's all I was pondering. See also: http://news.ycombinator.com/item?id=230272 http://news.ycombinator.com/item?id=230272 . I think my tone may have been misunderstood. And the land bridge didn't melt, because it's made of land, and land doesn't melt. :) What happened is that the sea levels rose due to melting glaciers on the continents and flooded it. It's still there, it's just a shallow sea instead of a connecting lowland between asia and alaska. I stand corrected. I had learned incorrectly in grade school, apparently (not surprising). I did see my error when reading the Wikipedia page; I'm not sure why I didn't edit my post. Let's pretend the definition I was referring to was: 3. to pass, dwindle, or fade gradually (often fol. by away): *His fortune slowly melted away.* ;-)
