The animation below flashes between the average of measured adjusted USHCN temperatures, and the estimated (infilled) ones – which are marked with an “E”
As you can see, all US warming since 1990 is due to infilling fake data. And even the measured zero warming temperatures have been tampered with using various other adjustments.
USHCN is losing data at a spectacular rate over the last three years, with more than 50% of the 2015 data marked as estimated, and nearly 40% of the 2014 data marked as estimated.
Temperature analysis reported by NCDC to 0.01 degrees are scientific malfeasance. They probably aren’t accurate within 1.0 degrees.
