No. Temps could have gone up or down during these 5000 to 12000 year periods. In fact we do see evidence of this in the saw tooth behavior which is a sign of slp stick behavior common in almost all chaotic events. The slopes could have been anything in between. No one has any idea what happened between the two points because no one has the data to analyze what happened between the two points. In fact, one would have expected them to behave exactly as we see today. At what point are you going to acknowledge that the data clearly shows that our present temperatures are at least 1.4C to 2.4C below the peak temperatures of three of the last four interglacials?You are an idiot. It doesn't matter what happened in those intervening 7000 years. It only matters where you set the endpoints. And you're still too inept to explain how to account for a 10x difference in slope. 20% or 30% maybe. Not a 10x difference.
