I linked to the EPA. Not to opinion.
What's Known Scientists know with virtual certainty that:
Human activities are changing the composition of Earth's atmosphere. Increasing levels of greenhouse gases like carbon dioxide (CO2) in the atmosphere since pre-industrial times are well-documented and understood.
The atmospheric buildup of CO2 and other greenhouse gases is largely the result of human activities such as the burning of fossil fuels.
An “unequivocal” warming trend of about 1.0 to 1.7°F occurred from 1906-2005. Warming occurred in both the Northern and Southern Hemispheres, and over the oceans (IPCC, 2007).
The major greenhouse gases emitted by human activities remain in the atmosphere for periods ranging from decades to centuries. It is therefore virtually certain that atmospheric concentrations of greenhouse gases will continue to rise over the next few decades.
Increasing greenhouse gas concentrations tend to warm the planet."
The data shows that the world is warmer.

The data also shows that the world began warming 14,000 years ago. I may be missing something, but I don't recall SUV's cruising around back then. The graph only tells you that the world is warming. We know that. The cause is what is being argued or is that beyond you?
So far, no data has been presented by the warmist camp, that shows man is responsible for the warming. Instead, the only empirical evidence we have counters their fundamental tenet (and yes I am using that term intentionally) that CO2 is the cause of the warming.
The best evidence for CO2 having no correlative responsibility for the warming is the Vostock ice core samples which show unequivocally that warming occurs first and then 800 or so years later the CO2 levels rise.
That means the current CO2 level rise we are witnessing can be just as reasonably attributed to that cause, as to any other cause put forth. It is after all around 800 years since the Medieval Warming Period and the temps were demonstrably higher globally then, then they are now.
To further put the nail into the coffin of CO2 being a temperature driver, those same ice cores show that during the Holocene Thermal Maximum of around 8,000 years ago the temperature warmed, hundreds of years afterwards the CO2 levels increased, then there followed 300 or so years of cooling,
and the CO2 level remained elevated, then there was a further 300 year period of warmth followed by a further 300 year period of cooling, then the CO2 levles finally began to drop again after 1000 years of elevated levels.
So, you see, the very theory of AGW has been proven false. That single study (kindly provided by olfraud) refutes everything you have built your entire religion upon. And yes, yours is the faith based belief. Why else would your high priests engage in the persecution of "heresy" they proclaim?
It is your side that is attempting to squash dissent. It is your side who persecutes the "blasphemers of the "word". It is your side that has engaged in the wholesale denial of studies that counter the belief system they have instituted. You are the folks running the Inquisition now.
Thank you for making it so obvious.
