The National Climatic Data Center has broken last year’s record for misleading the public about US temperatures. The thermometer data they use shows no warming over the past 90 years, and that 2013/2014 were two of the coldest years on record in the US. But after data tampering, they report a sharp US warming trend. The animation below flashes between the average measured and final temperature at all stations.
The total amount of tampering reached record levels in 2014, at almost 1.8 degrees F. They create the appearance of warming by cooling all years prior to 2003, and warming all years since that date.
Another spectacular milestone is that the now fabricate 30% of their monthly data. Almost one third of their reported monthly station data has no actual thermometer data from that station. This allows them to contaminate missing rural data, with UHI affected thermometers tens or hundreds of miles away.
The physical basis of their tampering appears to be the amount of CO2 in the atmosphere. The correlation between tampering and atmospheric CO2 is almost perfect.
It appears that they have a tampering algorithm designed to force reported temperatures to match hopelessly broken global warming theory. NCDC says that the algorithm is “working as designed.”
