Temps rose as fast as the past 40 years around 1890-late 1930s. Then there was a reduction in global temps from then until the late 1970s. Now temps are (supposedly) rising again.
Industrial output/man made CO2 was of course way worse 1890s-1930s than the next dacades which saw huge increase in CO2 output, but those temps went down.
There's also the problem that measuring devices have changed radically over the past 50 years. And a lot of these sciencetards will compare data sets that were done with mercury thermometers 100 years ago to current satellite IR data. And if the old data set doesn't fit their narrative, they will just say 'oh, that reading was probably bad, so we need to do some science shit on it (IE noodly bullshit subjective math) to make it fit our narrative...of course when it does fit the narrative, then that data is all good. Or they will make up datasets from the past using subjective noodly math in order to compare. So many assumptions in these equations that they are as good as useless, it's here that they can inject whatever narrative they want (in the assumptive parts).
You have ice cores, which are used for this 'temps are rising faster than ever' bullshit, but the difference in temp differentiation is so small, that there is no way to accurately plot that to within a tenth of a degree as they claim using ice core samples.
