Failed Math: In 1997, NOAA claimed that the Earth was 3.83 degrees warmer than today
Climatologist Dr. John Christy said it best: “If you want the truth about an issue, would you go to an agency with political appointees? The government is not the final word on the truth.”
Meteorologist Anthony Watts: ""The point to be made here is that NOAA professes to be an expert at telling the public what the temperature is, when so many contradictions and errors creep into what is presented to the public, we should all learn to take what NOAA says, and what the media says with a grain of salt.
When you look at temperature that isn’t biased by continuous adjustments, such as NOAA’s highly questionable fiddling with sea surface temperature data this year, you find that 2015 was not the hottest record at all according to the U.S> Climate Reference Network data, which is a state of the art system designed to need no “corrections” of any kind. 2015 comes in third for the USA:
If NOAA can’t keep a simple claim accurate, such as what the GAT was in 1997 versus 2015, why indeed should we trust them? We shouldn’t, we should question everything, always, because it seems the global temperature is not only nothing more than a statistical construct, it is as fickle as the political wind.
Meanwhile, satellite temperature data, which NOAA and NASA don’t like to use, shows the Earth as third warmest in 2015."
Yesterday, to much media fanfare, wailing, and gnashing of teeth NOAA pronounced that 2015 was the hottest year on record, ever! There’s only one problem with that…the Internet never forgets. Back in 1997 after the super El Nino made global temperatures soar, NOAA/NCDC produced this report:

In that 1997 report, they say clearly that the Global Average Temperature (GAT) was 62.45°F, based on a 30-year average (1961-1990) of the combined land and sea surface temperatures. Since we know the 1997 El Nino caused a record high spike in temperature, that means that for that 30 year period, there was no warmer GAT than 62.45°F up until that time.
Yet in 2015, the claim for the “warmest ever” GAT is different:
They say:
During 2015, the average temperature across global land and ocean surfaces was 1.62°F (0.90°C) above the 20th century average. This was the highest among all 136 years in the 1880–2015 record, surpassing the previous record set last year by 0.29°F (0.16°C) and marking the fourth time a global temperature record has been set this century.

In the 2015 Annual State of the Climate report referenced above, NOAA says that the temperature was 1.62°F (0.90°C) above the 20th century average. That’s an important number. While they don’t reference the absolute value of the 20th century average temperature for the globe in that report, we can find it here in the November 2015 State of the Climate Report:
