Here's an additional point. I haven't seen "An Inconvenient Truth" but a good friend did, and he said that the movie states that receding glaciers, and loss of ice, worsens "global warming" because of less reflective surfaces.
I was interested in this point, b/c I made the same point in the opposite direction when the Great Lakes froze over a few years back (first time in 15 years or some such).
Ok, now we have snow, 3 weeks early. Not only are temps colder, but this is more highly reflective snow covering the surface, reflecting solar radiation back into space, at a time when more sun is shining on the ground.
What's this going to do w/ the global warming balance?
In short, these things are not well accounted for in models, so the conclusions from those models are overstated, or even flawed. In other words, "junk science".
