Data on global warming?

Personally, I believe in moderate amount of global warming, in which humans are at least a partial contributor.

Also, I personally know some people who think that global warming is a government conspiracy created by the Democrats to take control of the United States.

I need to win this argument, and I want your help.

I need data, lots and lots of data on global warming patterns, as well as historical rates of temperature, rainfall, and atmospheric composition that dates back both as far as possible and as detailed as possible. I want rates of greenhouse gas emissions. I want statistics on ice cover and hurricanes. I want data on the rate of temperature record breaking, and proof that this isn’t random chance.

There are three rules: First, I need links to the original sources. Second, I need a wide variety of credible sources. Third, there is no such thing as too much data.

Bring on the information overload!
