Jo Nova give a point by point summary of what we knew which Anthony Watts has proved in his new paper.
1. There goes half the warming trend. The most accurate thermometers in the right places are not recording high trends. High estimates come from combining good records with poor ones then adjusting that up.
2. They show Mueller and BEST’s latest exaggerated claims of 1.5C are meaningless.
3. They show that only class 1 and 2 stations (which are placed well, not next to concrete, car-parks, or air-conditioners) give reliable data and the warming trend from these stations is much lower than the warming trend from Class 3, 4 or 5 stations. It’s what we always knew — thermometers near artificial heat sources are measuring artificial warming, but it’s not the global kind.
4. Mueller, BEST, GISS, Hadley and all the others should have removed the data from poor stations entirely. No amount of statistical chicanery can correct the artificial warming effect no matter how you adjust, blend, or homogenize the data.
5. Worse, the adjusted data shows an even warmer trend than the warmest and worst stations. That casts a very dark shadow indeed. How honest or impartial are the scientists who adjust data from stations with thermometers near air-conditioners and create more warming? Bad stations have been adjusted up, instead of down, and then the good stations were adjusted up to match the now-really-awful-bad ones. The stench of failure and a lack of dedication to the truth in on show… |
