We know atmospheric CO2 levels are up dramatically. We know temperatures are up. We have a good theory on how CO2 (and other gases) could make temps rise. I know climate has varied a lot in the past, but between strong correlation + mechanism I'd say human causation is likely.

That said, we all know that concern about global warming is just pushed by people of coldness trying to force their climate values on everyone else. Whitey just wants more ski resorts.

the earth goes thru glacial periods, the earth is gonna continue to warm and sea levels continue to rise until we hit the inflection point and move into the next ice age

That's the big picture, for sure, but you're not suggesting that the realistically predicted climatic effect of CO2 liberation is zero (are you)?

it seems unreasonable that it should be zero, doesn't it? The greenhouse analogy is so striking! yet it's also unreasonable that after 30 yrs the models still have no predictive power...

No reason to trust the models on quantity of temperature change, but I do trust the likely mechanism of CO2 blocking some wavelengths of radiation coming from the Earth.

I don't mean to overemphasize this one factoid, but circa 1970 the idea was that CO2 would start a cycle of increasing cloudcover, block *incoming* radiation and freeze the earth. There are now "obvious" reasons that doesn't happen: but these mechanisms are never immaculate

But the incoming radiation has a lot more visible wavelengths, and as far as I know CO2 absorbs much more in the IR.
