With elementary school knowledge of history we can know that the the earth was warmer 1000 years ago than it was today. It's sad that it takes a billion dollars to get this simple truth out, but in the face of the billions of dollars at stake for special interests, governments, and UN beauracrats, it's sadly the case.

Can you (a) back this up and (b) explain why it's relevant?

  I think the commenter is referring to the "Little Ice Age" which we do have a substantial amount of evidence for. http://en.wikipedia.org/wiki/Little_Ice_Age http://en.wikipedia.org/wiki/Little_Ice_Age It would suggest that the climate fluctuates even during periods where carbon emissions from humans was far less than today.

    Another term to search for is, Medieval Warm Period It has been warmer before on Earth while people have been around. There have been articles as early from 2003 I can find in the Telegraph but like all views not following the "common consensus line" they are mocked, derided, or ignored. From where tree lines ended on some mountains covered by snow, to the Vikings being able to navigate areas of the ocean that have ice this day. From where crops were grown then to today, there are many identifiable items from that period which point to a warmer climate than any we have. If anything this article could read, 1 billion dollar network goes up against the 1 trillion or more dollar Global Warming industrial machine. There is a lot of money in GW and those making it don't want it threatened.

      If that's true, it still doesn't follow that human activity isn't warming the climate, or that we can take the additional warming right now without enormous disruption. I call non-sequitur.

        This information is provided to plant some reasonable doubt to anthropomorphic gw and to suggest there's larger forces at play here than greenhouse gasses. It is relevant but it is not "proof" of anything on it's own, aside from the Earth's climate can shift substantially within short periods without any human contributions.
