The only way the “warmists” get the high temps they do, is when they use (and fudge) the very unreliable land temps at stations [most in fact] that are in areas that add an artificial heat to the real temperature.
- NOAA’s adjustments to previous ocean temperatures between 1998 and 2012 made recent global temperature changes appear more than twice warmer than the original records showed (Dr. Larry Bell, NewsMax)
- “To manufacture warming during the hiatus, NOAA adjusted the pre-hiatus data downward” (Daily Caller)
REAL SCIENCE notes that before “the year 2000, NASA showed US temperatures cooling since the 1930’s, and 1934 much warmer than 1998.” Continuing RL says:
- Right after the year 2000, NASA and NOAA dramatically altered US climate history, making the past much colder and the present much warmer. The animation below shows how NASA cooled 1934 and warmed 1998, to make 1998 the hottest year in US history instead of 1934. This alteration turned a long term cooling trend since 1930 into a warming trend.
However, a stark contrast to now is still wrapped up in this graph:
NOAA/NASA use only land-based temps to claim 2015 hottest year ever
Using data from heavily adjusted land-based temperature readings, NOAA and NASA declared yesterday 2015 to be the ‘hottest year ever,’ even though they’ve excluded the satellite record, and worse, ocean temperatures. That’s important because “70 percent of the Earth is oceans,” and “we can’t measure those temperatures very well,” says MIT’s Dr. Richard Lindzen. “The ocean temps can also be “off a half a degree, a quarter of a degree. Even two-10ths of a degree of change would be tiny but two-100ths is ludicrous.”
As for 2015? The satellite record shows it as being only the third or fourth warmest since satellite tracking began in 1978. The satellite data, which is compiled and maintained by the University of Alabama/Huntsville, found “2015 to be third warmest on record, and Remote Sensing Systems satellite data ranked 2015 as the fourth warmest in the nearly four-decade-old satellite record.”…
In the above graph, you have lines showing GREAT warming… waaaay above the 30’s to 40’s. HOWEVER, these have been adjusted… that is, the red “raw” data is the ground stations temps… the two lines above it, the blue one (TOBs-Adjusted) and green one (Homogenized) have been monkeyed with. A researcher lightened those lines and put the bolder “pink” and “purple” lines showing data from satellites (NASA). (Much of that blurred out data is milked from measuring units discussed in my post after a Christmas discussion about 2014 being the hottest year on record)
…Just for grins, I plotted the UAH and RSS satellite time series on top of the Hausfather graph…. I think can see why the so-called consensus has become so obsessed recently with destroying the credibility of the satellite data.
(WUWT … read it all for better context)
Now the truth is revealed… in that these persons cannot dabble with the preciseness of the satellite data. And why recent attempts have been to discredit it because it discredits their pet theory.
Climate Depot continues the “heresy”!
NASA and NOAA today proclaimed that 2015 was the ‘hottest year’ on record.

Meanwhile, satellite data shows an 18 plus year standstill in global temperatures.
MIT climate scientist Dr. Richard Lindzen balked at claims of the ‘hottest year’ based on ground based temperature data.
“Frankly, I feel it is proof of dishonesty to argue about things like small fluctuations in temperature or the sign of a trend. Why lend credibility to this dishonesty?” Lindzen, an emeritus Alfred P. Sloan Professor of Meteorology at the Department of Earth, Atmospheric and Planetary Sciences at MIT, told Climate Depot shortly after the announcements.
“All that matters is that for almost 40 years, model projections have almost all exceeded observations. Even if all the observed warming were due to greenhouse emissions, it would still point to low sensitivity,” Lindzen continued.
“But, given the ‘pause.’ we know that natural internal variability has to be of the same order as any other process,” Lindzen wrote.
Lindzen has previously mocked ‘warmest’ or ‘hottest’ year proclamations.
“When someone says this is the warmest temperature on record. What are they talking about? It’s just nonsense. This is a very tiny change period,” Lindzen said in November 2015.
Lindzen cautioned: “The most important thing to keep in mind is – when you ask ‘is it warming, is it cooling’, etc. — is that we are talking about something tiny (temperature changes) and that is the crucial point.”
“And the proof that the uncertainty is tenths of a degree are the adjustments that are being made. If you can adjust temperatures to 2/10ths of a degree, it means it wasn’t certain to 2/10ths of a degree,” he added.
