Turns out the sun has more to do with global temperatures than just about anything. I don't know if it's in one of those lectures (it should be), but the sun had a pretty hot 1000 years there where it also released more radiation. This actually impacts radiocarbon dating.
You do realize that taking historic temperatures are pretty difficult and we can only get an approximation? Meaning, you may only get the historic average over a given 5, 10, 50 years when looking at historic data. Meaning some years may have been 5°c warmer on average, while others were 5°c lower on average. We simply can't know.
Regarsless, the point of my comment is still relevant. This has happened before, it will happen again. We should try and minimize damage, but also keep the perspective that in the past tempratures have fluctuated more and faster. It's been warmer and colder on our planet, and everything will adapt.

yeah, I'm going to go out on a limb and guess you haven't done a lot of research on this. Short of super volcano winter you aren't going to see more than a tenth of that in annual variation.

No, it's really not. Not only was your initial claim wrong, but your point seems to just be that "changes happen", which is vacuous in and of itself.
Some day we'll reach the heat death of the universe. Why do anything at all, am I right?

You'd be wrong, I have done a lot of research. The fact is, we can only sample averages based on decades at a time. Meaning, even if a temperature is (like I said) 5°c warmer in year 1, then 0.5°c cooler until year 20, then rise again 0.5°c for the next 10 years, the gaussian of the sample would put the temperature is roughly 2.5°c cooler than today for that 30 year window.
You have to look at how this data is gathered, it's through melting ice mostly. Which is not an exceptionally accurate measurement.
And all my points have been the same (before a bunch of people came and down voted), life will go on and this is normal. Extinction events happen every few thousand years. Yes we are the cause, and no I don't think we shouldn't do anything. However, I also don't think we should ignore the fact that historically this isn't rare.
Source? I can't find anything to back that up.
