The MWP exceeded the temporal resolution of that proxy. Big whoop. That has nothing to do with individual versus group proxies. Proxy data aren't thrown together in a bag and poured out on the table. Each is treated individually according to its characteristics: its scaling factors, its range, it's temporal resolution and so forth.
You've got to stop assuming that folks with PhDs who've been doing this sort of stuff all their lives and are following on other PhDs who did it all their lives, know no more than do you.
There sure IS a difference between individual proxies. Especially the specific TYPE of proxy used. That ice core study you gave me in that other thread DEMONSTRATES this. Because the slices were taken at MUCH finer increments. You can't DO that for a 10,000 year proxy.. Not only that -- but there is less filtering done on individual proxies resulting in maybe 3 or 4 times the sampling resolution. Don't believe me -- read Marcott's comments above in the thread. The INDIVIDUAL proxies had inherent temporal resolution in the range of 100 years. The MERGED and HOMOGENIZED multi-proxy result had NO temporal resolution at 300 years. And reduced resolution out to 1000 years. That's not a temperature record. It's a very crude estimate of LONG TERM mean values of temperature.
The "big whoop" that you STILL DON'T GET is that Mann/Marcott others did not get good fidelity on KNOWN events less than 500 years --- So they in NO WAY could show a 100 year event like this modern one.. I've shown you MANY HIGH RESOLUTION proxies that show variations of 1deg or more local to those individual samples. And fairly COMMON as well.. You've forgotten all that for sure.
