Record and near-record breaking temperatures dominated the eastern two-thirds of the nation and contributed to the warmest March on record for the lower 48 states, a record dating to 1895, NOAA said.
The average temperature of 51.1 degrees was 8.6 degrees above the 20th century average for March and .5 degrees warmer than the previous warmest March in 1910.
Isn’t that convenient.
NOAA adds a little more than 0.5 degrees on to 2012 temperatures, and subtracts a little less than 0.1 degrees from 1910 temperatures. By doing this, they were able to make a press release saying that 2012 was warmer than 1910.
Chances are that the raw thermometer data was warmer in 1910. But we will never know, because they only release numbers which have been tampered with.

Please explain – does the graph show the adjustments to the raw data?
Yes. it shows how much they add or subtract to/from the raw data.
With expanding UHI effects, the corrections should be exactly opposite what they do.
Have they (I presume James Hansen) ever:
– Shown the change that was made
– Given the reasons why the change was made
– Provided the source of the new data
Hard to believe that there are only one or two data points over the last century that agree between his numbers and the instruments of the time.
(Especially since they accept as gospel the water temps taken by a single ship with a hand manipulated rope)
Where’s the data post-2000?
It does not matter where the data is because the data is FUBAR! The surface temperature records are fairy tales and have little or no relationship to reality.
It’s still in a state of flux….. we have to wait until its about 20 years old to be able to start tracking the changes…… the temps, they move so much when they’re young…… But, when they’re young they’ve got stamina to see the race through!!! http://wattsupwiththat.com/2010/12/25/do-we-care-if-2010-is-the-warmist-year-in-history/
Scroll down and look for this, “The Great Hot 1934 vs 1998 Race”….
Interesting paper published in the International Journal of Modern Physics, and not written by the usual suspects. (aka “The Team”.)
“For the period 1906-2005, we evaluate a global warming of 0.58 C as the mean for all records. This decreases to 0.41 C if restricted to stations with a population of less than 1000 and below 800 meter above sea level.”
“As a result, the probabilities that the observed temperature series are
natural have values roughly between 40% and 90%, depending on the stations characteristics and the periods considered.”

I expect that if HUMAN caused warming includes data from instruments next to Air Conditioning exhausts, then yes, indeed we are causing it.
An argument I used back in my blog days – there is no such thing as average temperature that can be used for comparison. Oh sure, disingenuous people can make a case to use this thermometer and this tree ring and this other thing and come up with a graph – but they are, by definition, lying and are liars that cannot be trusted.
Far better data comes from anecdotes – what were people saying at the time.
