Tony Heller of RealClimateScience.com: "This warming trend since 1970 does not exist in the thermometer data, so where does it come from?
There has been a large decrease in the number of stations reporting data over the past 30 years. But in the final adjusted data set, they use temperatures for all 1,218 stations regardless of whether or not there is actually any thermometer data.
In other words, they are simply making up data. More than 40% of the data in the final data set is now fabricated.
NOAA US temperature graphs are completely fraudulent, and they are being adjusted upwards to track CO2.
Many of the world’s leading models are now projecting warming rates that most scientists, including the modelmakers themselves, believe are implausibly fast. In advance of the U.N. report, scientists have scrambled to understand what went wrong and how to turn the models, which in other respects are more powerful and trustworthy than their predecessors, into useful guidance for policymakers. ... Climate models used by next month’s Intergovernmental Panel on Climate Change report project more warming over an 1850–1900 baseline than those in a 2013 report. Scientists are using recent observed warming to rein them in.
