ice cores and the temperture record

It seems like the watts up author like chogan2 has put up a hard to read plot that really doesn't say anything because of the scaleing. Then he has used some distortions that he seems to imply is ok 'cause gore did it.

Look at the page I refereed you to, and you can clearly see the cores from antartica show it was colder while Greenland was warmer

Ice Cores
Its in figure 7. Figure 4 shows a more high resolution of Antarctica. I put my comment only to clarify, but that watts up piece seemed to be there mainly to distort.


Steffensen does talk about a very quick warming period that may have warmed faster than today that is consistent with the antarctic cores. He appears to be a skeptic to man being a main driver behind climate change, but he does not seem to fall into the distorted charts, only a longer term perspective. He also disagrees with the hypothesis that ghg warming is the only thing that is going on.

Which gets back to the question, how good are the proxies, and how good are the models that use them. If the ice cores are extremely accurate for a 50 year period within the last 15,000 years, we do need to reject the hypothesis that the earth has never warmed this fast before. We also need to understand that this is comfirmatory evidence that there are tipping points, and there is the possibility that Anthropologic contributions may be pushing the world towards one. But I would rather stick to the science instead of the politics behind that last statement.

 

You seem to not like the graph I presented, but... these graphs show more raw proxie data. If you have a better model for both local and global temperatures great. But otherwise why not use a mathematical model that uses both hydrogen and oxygen isotopes which should be more accurate, as the section I quoted suggested. The reconstruction I posted is consistant with these proxy graphs.

Now onto your point.... The ice age ended 9703 BCE, according to greenland records, from previous post. It all depends on where and how you define it. Interglacial starts then. It was warmer in greenland most of the time in the interglacial. In antartica is was colder most of the time. On other places on earth, I simply do not know. I also am skeptical about the errors reported in proxies as we seem to continuously find new data and models moves things beyond the error bars.
