I responded on Turn Left. The sources in here do not support your conclusion that greenhouse gas emissions play no significant role in global warming. At most, they strongly indicate that some of the recent increase in temperature on Earth is due to an increase in solar radiation. The size of this effect is not quantified, but appears insufficient to account for the rise by itself. It still seems like a smart bet to attempt to reduce the increases in greenhouse gas emissions as a way to slow up the warming. Since it also means saving resources, it's a winner all around if you don't own an oil or coal company.
