NOAA Caught Rewriting US Temperature History (Again) | Power Line:
NOAA CAUGHT REWRITING US TEMPERATURE HISTORY (AGAIN)

We have written a number of times about how government agencies, including the National Oceanic and Atmospheric Administration here in the U.S., have systematically adjusted temperature history to make the past look colder. 
They apparently do this, usually surreptitiously and without explanation, in order to stoke global warming hysteria. 
See, for example, He Who Controls the Present Controls the Past and Inside the Global Warming Scandal.

Now Mike Brakey, an engineering physicist and heat transfer specialist, has caught NOAArevising historic temperature data for Maine–as always, to make the past look cooler and the present warmer by comparison:

Over the last months I have discovered that between 2013 and 2015 some government bureaucrats have rewritten Maine climate history… (and New England’s and of the U.S.). This statement is not based on my opinion, but on facts drawn from NOAA 2013 climate data vs. NOAA 2015 climate data after they re-wrote it.

We need only compare the data. They cooked their own books (see numbers below...).

This graph presents the data visually.
The black line shows average annual temperatures for Maine from 1895 to the present as they were recorded at the time, and as NOAA published them in 2013.
Thermometers have recorded no net warming since 1895.
The blue line represents NOAA rewritten history as it appears in 2015.
Note how NOAA reduces earlier temperatures more than recent ones to give the graph a plausibly warming trend.
The green line shows average annual temperatures for a single location, Lewiston-Auburn, showing a steep decline since 2000. Click to enlarge:

NOAA has made similar adjustments to past temperatures around the United States. Brakey writes:

It appears NOAA panicked and did a massive rewrite of Maine temperature history (they used the same algorithm for U.S. in general). The new official temperatures from Maine between 1895 and present were LOWERED by an accumulated 151.2°F between 1895 and 2012.

In my opinion, this is out-and-out fraud. Why did they corrupt national climate data? Global warming is a $27 billion business on an annual basis in the U.S alone.

Now NOAA data revised in 2015 indicate that 1904, 1919 and 1925 in Maine were much colder than anything we experience today. (See the scorecard above comparing the NOAA data that are 18 months apart). Note how for 1913 the NOAA lowered the annual temperature a whole 4°F!

For the balance of the years, as they get closer to the present, the NOAA tweaks less and less. They have corrupted Maine climate data between 1895 and present by a whopping accumulated 151.2°F.

David Archibald writes:

Their cooling of the past to keep the global warming meme alive reminds me of the old Soviet joke – the future is known, it is the past that keeps changing.
