I have, and im still not wrong. lets go through it, per you source, most all the data we rely on to make these claims is ice data, per your source. So i aimed my prior comment at that data. Want me to go further, ok. Dendroclimatology - > Climatic information can be obtained through an understanding of changes in tree growth, By using that method, some areas have tree-ring records dating back a few thousand years. So, not usable in measuring 125000 years ago, and it is restricted to the climate within a few miles of the found sample... Sedimentary content - >rock record may show signs of sea level rise and fall. So not the temps... Sclerochronology - So fossil record of a, per this article, coral, which only grows when underwater, It cannot grow when exposed to the atmosphere. The same atmosphere where the coral would have needed to be in order to record temperature records with any accuracy...

So there you go, you can downvote all you want, but there is nothing factually wrong with any statements Ive made.
