Lest you wonder, I see no doubt that Global Warming is happening, and it looks very likely that the activities of humans are driving it. Left to itself, the planet would probably be moving back into another Ice Age, since the last one ended ca. 12,000-16,000 years ago. As a scientist, I have to look at the hard facts, the real evidence. What I see indicates that global warming is well underway. Individuals and organizations for whom recognition of global warming might mean personal or financial inconvenience are still complaining and protesting; very few rational observers however doubt the reality of human-driven global warming. We're the cause of it, and we may be staving off the next Ice Age by our activities. I would prefer warming to glaciers, with limits.
