Whether a particular temperature station moved or not is not the only criteria to correct a bias. TOB (Time of Observation Bias) can also skew a graph if they move the time of checking the temperature from pm to am. There could be other biases besides moving.

Also, different stations have different ways of calculating the averages. There is a whole paper on all the different potential biases a particular station may have and hence the adjustment of data.

Meaning what? There are no unadjusted stations?

Kevin Cowtan describes the process of getting finding the global mean average which is really what global warming is about. Selecting a small sample (450) from a small area (the US) which have inherent biases in the data is virtually meaningless. I can find any trend I want.

Are you saying that U.S. measurements, which are what, 95% of all land measurements on the planet, are useless?

Also, if you look at the Geological QA paper, when you look at the entire globe, there were an almost equal number of adjustments down as there were up if you include the ocean data.
-
Wouldn't that mean the ocean adjustments were ten times more impactful on the average because oceans matter more than land for temperature?

In short, the adjustment process is necessary, otherwise, you are not reflecting the real temperature accurately. I linked all the technical refutations but they get lost in Twitterland since it has a poor debate structure.

Would you agree there is no standard by which they can know the adjustments were accurate?

To be completely rigorous, I would have to get the 451 station data from Gregory, find the history of each station and understand each adjustment and make sure it was justified. Then I could be absolutely certain there was not tampering. So far I don't have that history.
-
How the hell would that make you certain? All you would know is what scientists said they did to adjust. Would you check their work against the tree rings in your front hard to see it was done correctly?
