All Scientists are Sceptics ~Professor Bob Carter

Whenever someone asserts that a scientific question is “settled,” they tell me immediately that they don’t understand the first thing about science. Science is never settled. Dr David Deming

Perhaps the most frustrating aspect of the science of climate change is the lack of any real substance in attempts to justify the hypothesis ~Professor Stewart Franks

John Christy's testimony. More bad news for the Alarmists.

"When a theory contradicts the facts, you need to change the theory."

John Christy testified before the U.S. House Committee on Science, Space & Technology on  2 Feb 2016 (LINK -pdf)

Fig. 1: Five-year averaged values of annual mean (1979-2015) global bulk (termed
“midtropospheric” or “MT”) temperature as depicted by the average of 102 IPCC CMIP5
climate models (red), the average of 3 satellite datasets (green - UAH, RSS, NOAA)
and 4 balloon datasets (blue, NOAA, UKMet, RICH, RAOBCORE).

I shall begin with a discussion that was precipitated by an increasingly active campaign of negative assertions made against the observations, i.e. the data, of upper air temperatures. Figure 1 in particular has drawn considerable attention from those who view the climate system as undergoing a rapid, human-caused transformation into a climate to which people would have great difficulty adapting. This simple chart tells the story that the average model projection, on which their fears (or hopes?) are based, does poorly for the fundamental temperature metric that is allegedly the most responsive to extra greenhouse gases - the bulk atmospheric temperature of the layer from the surface to 50,000ft. 

As with all who show where the Warmists' greenhouse gas theory falls apart, John describes being
tossed into a world more closely associated with character assassination and
misdirection, found in Washington politics for example, rather than objective, dispassionate discourse commonly assumed for the scientific endeavor. 
John Christy goes into detail showing how the ground record is unreliable:

I closely examined individual stations in different regions and have come to the conclusion that the magnitude of the relatively small signal we seek in human-induced climate change is easily convoluted by the growth of infrastructure around the thermometer stations and the variety of changes these stations undergo through time, as well as the variability of the natural ups and downs of climate.” 
and defends the accuracy of satellites:
......the claim is made the satellites do not measure temperature. In reality, the sensors on satellites measure temperature by emitted radiation - the same method that a physician uses to measure your body temperature to high precision using an ear probe. Atmospheric oxygen emits microwaves, the intensity of which is directly proportional to the temperature of the oxygen, and thus the atmosphere.

John summarises:
In my testimony today I have given evidence that the bulk atmospheric temperature is measured well-enough to demonstrate that our understanding of how greenhouse gases affect the climate is significantly inadequate to explain the climate since 1979. In particular, the actual change of the fundamental metric of the greenhouse warming signature – the bulk atmospheric temperature where models indicate the most direct evidence for greenhouse warming should lie - is significantly misrepresented by the models. 

From John Christy's December Testimony

I have also attached an extract from my Senate Testimony last December in which I address

  1.  the popular notion that extreme climate events are increasing due to human induced climate change (they are not), and 
  2. the unfortunate direction research in this area has taken. 


  1. You deniers say that global warming has stopped but you know that isn't true.

  2. That was because NOAA manipulated data to get that result.
