First, the graph is clearly marked Climate4you. A simple Google of climate4you maturity graph will take you there. In fact, it has been updated once since I posted it, on Sep15, 2015. You will find info on many of the major global datasets.
Like I suspected, the graph does not include ocean temperatures. It excludes 70% of the data. GIGO.
Second, I have challenged you to discuss the pre-WWII ocean adjustments on several occasions and you declined. Apparently it is easier to make a general statement than to actually the specifics.
You haven't "challenged" anyone. You've babbled about buckets, but nobody can figure out why. Best guess is that it's your attempt at evasion. You've steadfastly refused to address the actual point that if one includes the ocean adjustments, as scientists always do, then the temperature adjustments make the total warming look smaller, which destroys your conspiracy theory.
Look, if some crank rants about how all the data on unicorn migrations is being faked to push a socialist agenda, I know to ignore it, because there are no unicorn migrations. There's no point spending effort refuting a total fiction.
Likewise, if some cranks rants about how temperature data is being adjusted to make warming look bigger, I know to ignore that craziness, being how the temperature adjustments are making the warming look smaller. Again, there's no point spending effort refuting a total fiction.
