What’s a “Proxy”

This is something that I find fascinating. In climate debates, there is this argument that “the proxies” (do) (do not) reflect the temperature. So I ask: What is a proxy? Apparently it is something that is used to provide evidence of temperature at some point in time. Sooooo. How is a thermometer NOT a proxy? Indeed, let’s get into the high end. How is an RTD (resistance thermal device),  with data logging software different from a tree ring in recording temperature? Much more precise than a tree ring (and if calibrated properly, accurate too), but nonetheless, substantially the same. Personally, I think “Proxy” is a misdirection. The appropriate term is thermometer. The results are readings. If the readings of the tree thermometers are substantially different from a well calibrated RTD, then I humbly suggest the tree thermometers are crap. And apparently, you have to hide the decline to mask this.
