As a student of Climatology, I have observed that for every scientist that supports the "Scientific Theory" of global warming. Just as many disagree. A "Scientific Theory" isn't just someone making a hunch though. This comes about after years of observing, recording data, coming to an opinion on a matter. Then testing it, and seeing if all adds up. This is a huge matter that is intensly debated & divided by prominent scientists worldwide.
I think there is a problem. But I agree with Jmace that there are more pressing issues to "Worry" about. Unless your only worry is climbing snow in August.
By the way, that is a great photo AlpineDave
