is it reasonable to accept this chart?
earliest thermometers are from, say, 1600s.
widespread temperature recordings are, at best, 200 years duration and not globally representative.
proxies from ice cores, tree rings, and sediment cores - even if an accurate proxy - provide local sampling and not global temperature.
and yet we can get to ⅒ of a degree accuracy!?
we should also note that this graph shows a 1.2 ⁰C range over 2000 years.
