Feynman laid down rules on how not to fool yourself when doing science. Google and read the speech.
Fast forward a few decades and compare climate science. They have stepped into all the pitfalls.
I am not going to rehash everything I have written over the last eight years but I will point out what happened to a minor proxy.
Boreholes show a general relationship to temperatures. There have been tens of thousands of them done. In the 90's, ~15,000 were averaged and the graph showed a warmer MWP. In the early 00's, Mann's hockey stick needed propping up and a new borehole graph was presented using only ~500 holes. It stopped before the MWP and showed a classic hockey stick shape. In the later 00's, the same author produced yet another graph using about 1500 holes. This time the MWP was evident but cooler than the present.
These three papers were all peer reviewed and written by a noted expert in the field. If there can be such wildly divergent conclusions based on the same trove of evidence, by the same author, how can we say the 'science is settled'? I hope you noticed that the first paper used most of the available data, the second only a small fraction, and the third slightly more.
Cherrypicking and dodgy methodologies are the hallmarks of climate science. Any preformed conclusions can be reached by choosing the preferred data and using the preferred methodologies.
