Heh, one article is all it takes to quash this discussion![:D] I wouldn't dismiss solar activity (sunspots, irradiance, etc.) as NOT being implicated in some form. There are interesting correlations that cannot be dismissed out of hand:

It's actually a very interesting discussion. I love how these arguments are always reduced to "either this or that". What about--god forbid--a combination of factors?!![:0]
I think that WE are definitely a contributor but the amount is arguable. I doubt it's 90% or some absurdly large number. Think about the huge increase in particulates in the atmosphere as a result of emissions that are causing another, less-discussed phenomenon: global dimming (
http://en.wikipedia.org/wiki/Global_dimming). Simply put, less sunlight is reaching us. This may even help explain why jet contrails seem to create cloud cover now when they almost never did back in the 1990s.
Nothing wrong with erring on the side of caution but I prefer not to flog myself with "green guilt" and carbon footprinting, especially in light of the uber-hypocrites leading the charge.
