“Gotcha” Graph from GISS

Lots of buzz over Brian Cox using the latest GISS land and ocean graph to put down Malcolm Roberts in a TV debate in Australia. Likely we will be seeing the image everywhere and alarmists crowing about “deniers” dismissed once and for all. For the record here is the graph showing no pause whatsoever:

This is accomplished by lowering the 1998 El Nino spike relative to 2015 El Nino. To see what is going on, here is a helpful chart from Dr. Ole Humlum at Climate4you

It shows that indeed, GISS is showing 1998 peak lower than several years since, especially 2002, 2010 and 2016. In contrast, the satellite record is dominated by 1998, and may still be in that position once La Nina takes hold later this year. The differences arise because satellites measure air temperature in the lower troposphere, while GISS combines records from land stations with sea surface temperatures (SSTs) to fabricate a global average anomaly, including adjusting, gridding and infilling to make the estimate of Global Mean Temperatures and compare to a 30-year average.

An insight into the adjustments is displayed below.

As we have seen before, the past is cooled, and the present warmed to ensure evidence of global warming. Presently it is claimed that July 2016 is the hottest month ever. But stay tuned for future adjustments necessary to keep the warming going.

Dr. Humlum demonstrates that GISS is an unstable temperature record.

Dr. Humlum:

Based on the above it is not possible to conclude which of the above five databases represents the best estimate on global temperature variations. The answer to this question remains elusive. All five databases are the result of much painstaking work, and they all represent admirable attempts towards establishing an estimate of recent global temperature changes. At the same time it should however be noted, that a temperature record which keeps on changing the past hardly can qualify as being correct. With this in mind, it is interesting that none of the global temperature records shown above are characterised by high temporal stability. Presumably this illustrates how difficult it is to calculate a meaningful global average temperature. A re-read of Essex et al. 2006 might be worthwhile. In addition to this, surface air temperature remains a poor indicator of global climate heat changes, as air has relatively little mass associated with it. Ocean heat changes are the dominant factor for global heat changes. (my bold)

Too much trickery going on. I prefer to see actual temperatures, and this graph presents clearly the GISS record without the distortions:


Or, if you prefer Celsius degrees (range represents human sensory experience of daily and seasonal temperature variability)



Brian Cox defended the GISS graph by saying it was from NASA who put men on the moon.  He forgot to mention that several of those men and many scientists who put them there find NASA increasingly unscientific and untrustworthy on climate matters.

It could also be said about the recent GISS graph:  You show us a graph where the past history is different today than GISS reported it a year ago, and different again from 5 and 10 years ago.  Why should we believe this one any more than the other ones?  And why does GISS contradict temperatures recorded directly by NASA satellites?

He who controls the past controls the future. He who controls the present controls the past.

Same point as Orwell, but with a dash of humour:

A soviet university professor addresses his students: “There’s good news and bad news about this year’s History final exam.  The good news is all the questions are exactly the same as last year’s exam.  The bad news: Many of the answers have changed.”

    The journalist was quite correct, an appeal to consensus is not science. For a long time the consensus was that the Sun and planets went round the earth. If you disagreed you were put to death. Perhaps, with that sort of appreciation of scientific method, Cox should offer his talents to the inquisition

    “This sort of deception isn’t a complete surprise, though, given the questionable study published last year by the National Oceanic and Atmospheric Administration (NOAA) [Karl et al].
    But it reveals the degree to which academic and government elites will pursue their own agenda at the expense of institutional honesty.” – Climate Change Dispatch

    Can I also add that your graph of Global Mean Temperature GIS (number 6 I think) is inherently wrong. Pedantically – The y-axis should be in Kelvin, deg C is an artificial temperature artifact base on the melting point of water rather than energy basis of temperature. One cannot really do physics in Celcius without setting the origin to -273.15 deg. Can you please redo this chart in Kelvin please?

      bobl, the GISS output is in degrees F, so I went with that. The graph has the advantage for people to compare what they experience (at least in N. America) on an annual basis: highs near 100F and lows below 32F.

      also Pedantically – the last two graphs’ y-axes should say “Degrees”


      • Ron Clutz · September 13, 2016

        Fixed. Thanks for catching that in peer review. Obviously I need help with vertical text.
