all past temperature readings.

What really concerns me is that I've
read a lot about climate models not being able to replicate the magnitude of abrupt regional
temperature changes in the
past, and Raypierre has said here that he fears that
past climate records point towards some yet unknown positive feedback which might amplify warming at the northern latitudes.

So, after
reading about climate change for awhile and how the «
Temperature of the Earth» has moved up and down in increments of hundredths of a degree, over the

I just thought that since the proxies are all (as far as I know) annual
readings such as tree rings or lake sediments they each can be determined to a precise year in the
past, and the global
temperatures are compared on an annual basis, perhaps you lose accuracy (or is it precision?)
The results of this proxy formula didn't match up with actual
temperature readings past 1960, so to make their method look like it had more skill (accuracy) than it did, they simply grafted the actual
temperature series to the end of the tree ring proxy
temperature series.
Reading all of these comments, my conclusion... any scientist who claims to understand the accurate

The current warming trend 1998 - 2005, has no precedent in recent Arctic memory, there were a few unique occasions when open water was seen during mid-winter over Barrow Strait, but this was at roughly 10 year intervals, now the intervals are totally irregular, but between Islands ice cover is not the best indication of warming, monthly
