Who the heck would have any idea what a “pre-industrial level” would be? Anyone who bothered to make such a measurement in, say, 1750 would be using instruments so crude as to be worthless.
Oh, wait. What am I talking about? When it comes to Global Warming accurate measurements aren’t necessary. Just make up the data, then raise the alarm.

Are you saying that using tree rings to determine the temperature is not that accurate?
