When Dr. Roy Spencer looked up summer temperature data for the U.S. Corn Belt, it showed no warming trend for over a century. But that was before temperatures were âadjustedâ by National Oceanic and Atmospheric Administration climate scientists. Now the same data shows a significant warming trend.
Spencer, a climate scientist at the University of Alabama in Huntsville, said that the National Climatic Data Center made large adjustments to past summer temperatures for the U.S. Corn Belt, lowering past temperatures to make them cooler. Adjusting past temperatures downward creates a significant warming trend in the data that didnât exist before.
âI was updating a U.S. Corn Belt summer temperature and precipitation dataset from the NCDC website, and all of a sudden the no-warming-trend-since-1900 turned into a significant warming trend,â Spencer wrote on his blog, adding that NCDCâs âadjustmentsâ made the warming trend for the region increase from just 0.2 degrees Fahrenheit per century to 0.6 degrees per century.
NCDC temperature data downloaded by Spencer in March 2014 looked quite different from data he downloaded this month. Thatâs because NCDC constantly adjusts its data to correct for errors, but critics have said these adjustments seem to always increase the warming trend for the U.S. or globally.
âBeing the co-developer of a climate dataset (UAH satellite temperatures) I understand the need to make adjustments for known errors in the data ⌠when you can quantitatively demonstrate an error exists,â Spencer wrote.
âBut a variety of errors in data measurement and collection would typically have both positive and negative signs,â Spencer noted, adding that he corrects for such errors when calculating satellite temperature data even if they tend to cancel each other out.
âIn contrast, the thermometer data apparently need to be adjusted in such a way that almost always leads to greater and greater warming trends,â he added.
Spencer is not the first to criticize NCDCâs adjustments to temperature data. Science blogger Steven Goddard (his pen name) has been arguing for years thatgovernment climate agencies have been tampering with temperature data to create a significant warming trend where none actually exists.
âNCDC pulls every trick in the book to turn the US cooling trend into warming. The raw data shows cooling since the 1920s,â Goddard told The Daily Caller News Foundation in a previous interview.
Goddard says that NCDC has been cooling past temperatures in the data to make the present look much warmer by comparison, bolstering the case that global warming is being caused by human activity and is rapidly getting worse.
âNCDC does a hockey stick of adjustments to reverse the trend,â Goddard said. âThis includes cooling the past for âtime of observation biasâ infilling missing rural data with urban temperatures, and doing almost nothing to compensate for urban heat island effects.â
Meteorologist Anthony Watts has also caught NOAA changing the temperature record. For two years, NOAA claimed that July 2012 was the hottest month on record â that is, until it quietly adjusted the data so that July 1936 was the hottest month on record.
âTwo years ago during the scorching summer of 2012, July 1936 lost its place on the leaderboard and July 2012 became the hottest month on record in the United States,â Watts wrote. âNow, as if by magic, and according to NOAAâs own data, July 1936 is now the hottest month on record again. The past, present, and future all seems to be âadjustableâ in NOAAâs world.â

The funny reaction to liberals every time they are confronted with truth that contradicts their pathetic arrogant know it all hypocritical dispositions.
