Personally, and IMHO (I dont wish to make enemies), I think that is reckless way to go about analyzing climate change. Scientific observation should be seperated from politics; climate change is not a policy issue.
Yes, it is true that the earth's climate changes on its own due to many factors - including water vapor, solar output (not controlled by man), orbit patterns (also not in our control), lunar patterns, and plate techtonics (yes, the same plates that cause earthquakes).
But - the most significant factor in earth's climate is atmosphere composition. There are obvoiusly many independent factors that control this, from volcanic activity, to plant life. However - using the fact that the atmosphere can change on its own to draw a conclusion that it cant change due to human activity is simply laziness. There is ample, ample data to support the fact that human CO2 emissions have, in fact, created an atmosphere that is not what it was before the industrial revolution. This isn't hippie propoganda, it's hard science - the fact that this issue has become so wrapped up in politics is unfortunate. It shouldn't be so difficult for humans to agree on something we all do.
