If I have correlated my proxy to a moving target, doesn’t that effect the likelihood that the proxy will yield useful information?
It would seem to me that this constant massaging of the database used to define and tune my proxy, would, in the end, destroy the utility of my proxy to deliver useful information. Evidence has been found for reduced sensitivity of tree growth to temperature in a number of forests at high northern latitudes and alpine locations.
Everything we know about past climate is based on “proxies.” As I understand the concept, science looks at “stuff” and finds something that tends to mirror the changes in temperature, or whatever, and uses that as a means to determine what the likely temperature would have been at an earlier time. So what we have, in essence, is a 150 year or so record of temperature readings to use to determine our proxy’s hopeful accuracy.
Now my question would be, if we are continuously adjusting the “readings” of that record, how does that affect the usefulness of the proxy information?

We explore that system of knowledge in this Educational Insight.elieving nothing, the skeptic is blind; believing everything, the naif is lame. A 2013 Harris Poll concluded that 29 percent of Americans (and nearly half of 18- to 24-year-olds) believe in or follow astrology.
Somewhere between the two lies the lauded land of viveka, discrimination, which neither doubts every inexplicable phenomenon nor swallows every unexamined statement. Galileo, the Italian mathematician and astronomer, cast charts on the side, as did the German celestial scientist Johannes Kepler. By contrast, 92 percent of the Chinese public think horoscopes are nonsense.
Gwalior was the winter capital of the state of Madhya Bharat which later became a part of the larger state of Madhya Pradesh.
Prior to Indian independence on 15 August 1947, Gwalior remained a princely state of the British Raj with the Scindia as the local rulers.
