Daily reminder that no actual long term significant warming has ever been measured. The only measurements going back to the nineteenth century are from the United States and they show no significant net warming. All warming has been added by pairwise homogeneity software because current "scientist" running past temps through spaghetti Fortran are more trustworthy than past scientist using a fucking thermometer somehow. Ground stations are still few in far between outside US and Europe, and satellites also haven't shown net warming until they are run through PH.

It's odd when PH was first introduced it was to detect small errors that mostly cancel each other out anyway. Hansen 1999 shows US data before and after running it through PH and if you didn't overlap the charts it's hard to tell any difference, but now PH is the whole fucking shabazzle. It went from a minor tool meant to clean data into the basis of the entire climate change narrative (perhaps because NO SIGNIFICANT NET WARMING HAS EVER SHOWN UP IN REAL MEASUREMENTS!).

Of course CO2 isn't causing warming. It's a weak greenhouse gas. Water vapor is a much stronger greenhouse gas and in the tropics it's like 40,000 ppm (compared to 400 ppm for CO2). But they argue that CO2 causes a positive feedback in H2O because more hotter means more water vapor. If that were the case wouldn't the H2O also positively feedback onto itself causing the entire planet hot and moist? Water doesn't know what the addition heat is coming from. It makes more sense when you observe that life still exists on Earth that the water has a dampening effect which has kept the cataclysms of the past from turning the earth into an unlivable steam planet.
