Well we can ALWAYS DO SOMETHING (even if it’s a meaningless fruitless gesture). We can obviously determine that our present global climate is optimum for human existence and since we have such a deep understanding of all of the variables involved we can not only accurately PREDICT weather for more than 48/72 hours but we can CONTROL our climate and all it’s variables (solar, tectonic, volcanic, etc) to maintain our optimum climate forever! We will no longer have to adapt to change as we become the gods we once worshipped. (Yeah, right…)

For a more constructive look at what we can do that doesn’t involve destroying our economy, creating more poverty and creating International Commissions look here http://www.lomborg.com/

As far as the “affirmative” points mentioned, climate change is made primarily first, last and primarily by the sun, and its variations. (Yes, the sun is a VARIABLE star!)

Not only THAT, there actually is a climate effect (with the mechanism described) from astronomical effects from OUTSIDE of the solar system, where cosmic ray variations changes the amount of overall cloud cover…hence, changes our climate…significantly in some cases. This science IS out there!

Anything we could do by accident, or by intent is insignificant compared to that. Temperatures rising? Maybe so…but not from US!

Climate change with “bad” consequences? It was measurably warmer during the middle ages (for example), and conditions were BETTER in most ways that count.

I COULD go on at length, and get way more specific (after teaching chemistry, physics, and geophysical sciences for 25 years I DO know how to find and understand scientific publication without filtering through AlGor or some politically motivated UN commission), and I expect to post on this more in the future (as I already have in teh past) as specific stuff comes out.

As far as playing “tit-for-tat” argument, I have found the “Pig Rule” rapidly comes into play: “Never mud wrestle with a pig. You both get dirty, and the pig likes it.”
