Too complicated to explain? Which means they are unable to craft a lie that won't be seen through.
The evidence of dishonesty noticed by me just piled up over the past decade. You don't need a PhD to know that half your county burned down in 1936.
Tim Ball said that Michael Mann belonged in the state penn, not penn state, for creating his fraudulent hockey stick plot. Michael Mann sued him for slander in Canadian BC court. After much time the judge ordered Mann to produce his raw data and methods. A real scientist would do that anyway. Mann refused, the judge threw out the case and assessed Mann some court costs.
To get into real details, in case some warmist knows this stuff.
1. There are adjustments for time of observation bias. Min/max thermometers that are reset in the afternoon can double count some hot days. The adjustment may or may not be the right amount.
2. Some temp stations are moved so adjustments may be made which may or may not be mischievous.
3. Corrections for urban heat island effects would heat the past or cool the present, not the other way around.
Tony Heller went through the temp record and only used temp records that had not been adjusted. Little warming was seen.
