Dr. Noor van Andel has updated his paper CO2 and Climate Change and explains in greater detail how climate scientists have adjusted radiosonde (weather balloon) data to try to bring it into agreement with their computer models and concept of greenhouse gas induced global warming. This is the opposite of the normal scientific procedure of adjusting the models to fit the data. The unadjusted data does not show the elusive "hot spot" predicted by climate models and conventional 'greenhouse' theory. Dr. van Andel's latest version also expands on the descriptions of Miskolczi's 'saturated greenhouse' theory and the cosmic ray theory of Svensmark et al.
"...This behavior has been a problem for many, as it falsifies a main point of the global-warming-by- greenhouse-gases- hypothesis. The warming by increased CO2 can only result from “increased back radiation” from the atmosphere to the surface, and for this the warming of the troposphere due to increased CO2 must be more than the surface warming. all models predict much more warming at 300 - 400 hPa compared to the surface warming trend. This is not observed.
There has been a large activity to bring models and observations in line, strangely only by adjusting the measurements instead of adjusting the models. The radiosonde measurements are adjusted so that they show the larger warming trend around 300 hPa that the models must assume to exist to get antropogenic CO2 induced warming, or to attribute the surface warming to increased CO2. Scores of publications and discussions try to prove this “atmospheric hot spot” must exist in the real world because the models say so. One example I show below:
From: Toward Elimination of the Warm Bias in Historic Radiosonde Temperature Records—Some New Results from a Comprehensive Intercomparison of Upper-Air Data, HAIMBERGER et al, JOURNAL OF CLIMATE, VOLUME 21, 4587) we take the following figure: Fig. 14 shows that the unadjusted 1979-2006 tropical temperature profile trends in the tropics, left graph, dotted line, shows a constant 0.1 K/decade warming with height until 200 Pa [11 km in the tropics], and above this height a substantial cooling trend, with a minimum of -1.2 K/decade [minus twelve times the surface warming trend!] at 70 Pa. Exactly like the fig.12 observations from Hadoffice show. This behavior is does not agree with the accepted theory of Greenhouse-gas induced global warming, that assumes a decrease of the convection activity with rising SST, because the temperature and moisture at 500-100 hPa in theory both rise, and this rising θe prevents convection. This is known as the “hot spot”. It is the main “positive feedback” assumed by the models to get the high climate sensitivity to be able to attribute the warming 1976-2010 to the CO2 increase. It is also called the “super Greenhouse Effect’. It exists only in climate models. This is the reason that so many corrections or adjustments have been proposed to the radiosonde measurements; the maximum adjustment [see left graph] reaching 0.9 K/10y, or 10ºC/decade from 1979 to 2009, that makes an adjustment of 2.7 ºC between the HadAT temperature measurement. and the unadjusted radiosonde measurement. Radiosonde sensors have a precision of 0.1 ºC! Physically it is impossible that convection decreases as the driving force for convection increases. Riehl & Malkus measured and quantified this deep convection in 1958 for the first time by flying into thunderstorms and derived the θe mathematics, which are soundly and simply founded in atmospheric thermodynamics. Thunderstorms are very local phenomena, they cannot and are not well parameterized in climate models. Clearly frequency and intensity of these storms is increasing fast with SST. Any CO2 in the atmosphere, if it would increase SST, is regulated back by this deep convective cooling mechanism.
The main error in the climate models is that they suppose heating and moistening, and thus higher θe [temperature], of the upper troposphere by CO2, in contradiction with radiosonde and satellite measurements. This assumed heating & moistening leads the model to assume an increase of θe [temperature] at this height, which makes deep convection decrease as a result of increasing SST, very unphysical as we have seen here above.
In the real world however, the upper troposphere will dry out as a result of stronger deep convection, because cloud top temperature goes down and condensation efficiency increases with deep convection intensity. In the region that the air spreads from the ITCZ and subsides, radiation into space is therefore enhanced. The lowest temperatures in the troposphere are to be found in the deep convection cumulonimbus tops, sometimes -80 ºC. All water is then in solid form, which coalesces easier and snows [rains] out more efficiently. This drying out has been documented well in the ERA and in the NCEP reanalysis historical time series. But it is hotly contested by IPCC- quoted authors, again because it is incompatible with climate models. "
