If we look at Karl2015, will we find lower past ocean temps and higher recent ones? How about the global temps (combined ocean and land)?
Your conspiracy theory predates Karl2015 by many years, which clearly shows you're tossing out Karl2015 as a red herring. Hence, there's no point in talking about it.
You don't seem to like specific comparisons. These large downward ocean adjustments, when ere they put in place?
Explain to everyone why that matters. That is, specifically explain your conspiracy theory. Best that I can guess, your conspiracy works like this:
The old good-aligned scientists impartially put in the ocean adjustments that make the warming look smaller.
Then, UN infiltrators brainwashed nearly every scientist on the planet.
The now-evil scientists now said "Oh noes! We should never have made the warming look smaller! We must fix that! But how can we do so without giving away our love of evil?"
After stroking their evil goatees for a while, they said "Removing those ocean adjustments is out of the question, even though it would by far be the easiest and most effective strategy. Instead, we'll add some tiny adjustments to the land temps that don't even come close to compensating for the ocean adjustments."
And then they all laughed their evil laughs, MWAHAHAHAHAH, and raised their glasses to make a toast, "TO EVIL!". <clink>
Good luck with that.
Since then what has happened? State YOUR version of events.
My version of events is that scientists impartially use all the data that results in more accurate results. Imagine that. Not a bit of conspiracy nonsense required, and it agrees with all the evidence.
