The past is getting cooler

In George Orwell’s dystopian novel “1984,” the “Ministry of Truth” was constantly changing historical records to conform with political policy of the present. The same thing seems to be happening with official temperature records.

With each new publication of the official temperature record, the past, especially the 1930s is shown as cooler than it was in earlier versions, and more recent temperatures are shown as warmer. This phenomenon is due to government data manipulation designed to make the present look warmer in relation to the past. This falls in line with the global warming scam that demands we reduce our carbon dioxide emissions and use the more unreliable wind and solar energy rather than burn our abundant fossil fuels, or dire consequences will follow.

Chief temperature tamperers in the U.S. are the National Climatic Data Center, part of NOAA, which maintains the Global Historical Climatology Network (GHCN), and the Goddard Institute for Space Studies (GISS) which is part of NASA.

Steven Goddard (no relation), proprietor of the blog Real Science, has a special page which documents the data tampering with many comparative graphs. Here is how GISS plotted U.S. temperatures in 1999:

US Temp 1999

And here is how GISS plotted U.S. temperatures in 2011:

US Temp 2011

Notice how the past got cooler? Note that the vertical scales are different between the graphs. However, look particularly at the year 1999 on both graphs. On the earlier graph, the 1999 temperature anomaly was less than 1 degree C and cooler than the 1930s. In the more recent graph, however, the 1999 temperature anomaly was more than 1 degree C and warmer than the 1930s.

GISS isn’t content to mess with just U.S. temperatures, they also revise world temperatures. For instance, Paul Homewood notes in his post, “Cooling The Past In Iceland” GISS made some “homogeneity adjustments” for Reykjavik resulting in these before and after temperature graphs:

Iceland temp before

Iceland temp after

Steven Goddard notes that the New Zealand government is into data tampering also and he compares before and after “adjustments” See post here:

New Zealand temp adjustment

It seems that in the realm of climate, government science is mostly political science. Good science has been corrupted by ideology and politically correct funding. It seems that Big Brother is in charge of government climate science.

P.S.:  Dr. Tim Ball has an interesting article on the IPCC’s promotion of climate alarmism and how they altered the records to conform with their agenda:

P.P.S. The National Climate Data Center adjusts temperatures every month. Here is a good explanation of why this always produces a warming bias (see full post here):

“The reason why station values in the distant past end up getting adjusted is due to a choice by NCDC to assume that current values are the ‘true’ values. Each month, as new station data come in, NCDC runs their pairwise homogenization algorithm which looks for non-climatic breakpoints by comparing each station to its surrounding stations. When these breakpoints are detected, they are removed. If a small step change is detected in a 100-year station record in the year 2006, for example, removing that step change will move all the values for that station prior to 2006 up or down by the amount of the breakpoint removed. As long as new data leads to new breakpoint detection, the past station temperatures will be raised or lowered by the size of the breakpoint.”
