Read my edit. I answered it already with an analogy that fits your temperature example perfectly. Read post #14.
I wonder how many times I've pointed people to post #14 now, and yet they continually result to red herrings, ad hominem attacks, etc.
Oh well.. Anyway, I hope you guys seriously look at what I'm saying here. I'd love for this aspect of science to be corrected, so that this inherent pre-bias will be resolved, and we can move forwards towards getting more accurate dates on things, to either back up the current estimates, or refute them. (I doubt that these posts will make any difference, but hopefully it has illuminated a glaring issue with this specific issue.)

It's funny how many times you've posted and yet you still haven't given me one environmental factor that will change the half-life of an element or anything that will screw up uranium-lead dating.
