> Cropping the chart to hide the outliers is so bad that I can't tell if they're incompetent or malicious It reminds me of the famous "hide the decline", when the climate scientists working on the famous "hockey stick" paper discussed how to hide in the graphs the recent decline of proxy temperatures while measured temperatures kept growing (which would put in question the general reliability of the proxies).

PSA: The divergence issue (aka hide the decline) refers to some tree rings in certain high altitude regions where the width of rings after 1960 would flatten or decline. However, there is evidence in the literature that the use of the bristlecone pine series as a temperature proxy may not be valid (suppressing "warm period" in the hockey stick handle); and that bristlecones do exhibit CO2-fertilized growth over the last 150 years (enhancing warming in the hockey stick blade). Further driving misreadings of the report is where the researchers refer to a a standard scientific practice as a trick. This standard practice is replacing the unreliable tree-ring data from 1960 onwards with actual thermometer readings. ref: https://en.wikipedia.org/wiki/Wegman_Report The hockey stick report does not refer to a decline in rates of warming. And since then, subsequent data has not only confirmed the hockey stick graph, it has pulled it slightly sharper. Featured two decades later now in the AR6 SPM is a longer Hockey Stick with an even sharper blade. And no longer just for the Northern Hemisphere, it now covers the whole globe. The recent warming is seen not only to be unprecedented over the past millennium, but tentatively, the past hundred millennia. ref: https://www.realclimate.org/index.php/archives/2021/08/a-tale-of-two-hockey-sticks/ I feel keeping science safe from bad actors and their misguided followers is our duty to do. My personal thanks to all who toil against corruption machines.
