The Anthropogenic Global Warming (AGW) cult is getting bold. They are actually showing us how much they have adjusted the raw temperature data and the data is hiding in plain sight.
The US Historical Climatology Network (USHCN) data set has seen numerous adjustments and the National Oceanic Atmospheric Administration (NOAA) tells us about them here. At the bottom of the page you’ll find this graph showing the total adjustments they’ve made to the USHCN data set since 1900.
Well, they have to do that or else they have to deal with the temperature data from satellites that show no warming over the past 17 years.
