Mark Albright has located a smoking gun of NCDC data tampering in Oregon.
In June, 1898 the US Weather Bureau reported that Oregon averaged 62.2F for the month, 1.7 degrees above normal. But NCDC reports that June, 1898 in Oregon was 56.4 degrees, 0.8 degrees below normal.
The US Weather Bureau normal in 1898 was 60.5F, and in 2014 the NCDC normal is 57.2F. In other words, Oregon was much hotter in the 19th century than it is now, and the NCDC US temperature record is meaningless political propaganda.
