Nope. That is not what I said. I said that paleo data because of the time spans involved don't show the fineness to assess any variations over small time spans.

I even cited Marcott's temperature reconstruction, he used 300 year smoothing over a 2000 year time span. Now i'll let you imagine what smoothing would be used over a 500,000 year time span. You do understand smoothing means you lose data?

Do you really have accurate records for the last 400-500 thousand years?

Here is how you opened - this is the standard you required. not exactly a short time span as you seem to be now saying.

You lose peaks and troughs not long term trends or averages the difference would make very little if any difference in the context needed here.

Oh dear. Can't differentiate between paleo and instrumental data.

Got a reference for that or is it a gut feeling? If you lose the peaks and troughs it must have an effect. Depends on whether the peaks are higher or the troughs lower or vice versa.

If the majority are positive peaks the overall outcome will be a bit higher and vice a versa.
