BS! By lowering PARTICLE EMMISIONS we risk lower the level of so called global dimming (which is just as much a theory as global warming). Interesting that you would believe such a theory and not global warming...
Its just more evidence that we don't actually know anything concrete.

No, what we are going on is scientific theory based on empirical evidence. Kind of like aerodynamics or relativity.
Cept for the whole competeing and huge wholes in the theory part of the comparison... But I really wouldn't be doing billions of dollars of damages to the worlds economy based on relativity back when it first came up. Hell I still wouldn't. Not that I don't believe it, but it hasn't been proven and the levels of poor on the street and deaths the sacrafice would lead to is hardly worth it based on a theory without facts to back it up.

Because the earth has natural climate change... Whats your point? Does that somehow mean that we are not able to contribute or indeed direct the direction of the cycles by tipping the balances of gas in the atmosphere? Volcanic erruptions have climate effects due to their gasious releases, why should our gasious releases not have an effect? Because we dont want it to and its easier to just burn oil? Head in the sand!

Heres a fun fact for you, the global agency for global warming does its calculations based on there being about 9 times more oil in the world yet to be found than the estimates by the saudis which is extremely generious itself.

There will be no more oil to burn by 2020 and thats the problem we should be worrying about.
