The real question is whether we are raising temperatures outside of what would be normally expected.



Exactly. Which is why looking at the last 2000 years, or even 400,000 years is pointless. You're looking at a tiny fraction of the data set to pronounce trends. That's ridiculous. If you're going to try to determine long-term trends, you've got to look at long-term data.

What happened one million years ago or even 20,000 years ago is not as important. Human civilization did not exist then and there was no reliance on agriculture.



Bingo! You're finally getting it. What was happening then? Is there documented evidence that mankind is making the climate warmer than it was before man's existence? Absolutely not.

Quote:

If we are indeed raising the global temperature, the consequences of climate change could be catastrophic.



But again, there is not evidence whatsover that we are.

Quote:

We are raising the temperature of the planet. That is not in question.



Yes it is in question. The temperature may be slightly rising in the extreme short term, but there is not one shred of evidence to say that it's being caused by humans. Not one single shred.

Quote:

What is in question is what effect it will have and what we can do about it.



See, this is where we humans need to get over our overinflated sense of self importance. There is nothing, I mean nothing, that mankind can do to the earth that the earth cannot recover from. You need to lose this silly notion that man has some particular importance in earth's history and that we somehow have some moral obligation to prevent natural changes.
