What really going on with the Climate?
The analysis and plots shown here are based on the following: first NASA-GISS temperature anomalies (converted to degrees Celsius) as shown in their table LOTI, second James Hansen’s Scenario B data, which is the very core of the IPCC Global Climate models which was based on a CO2 sensitivity value of 3.0 degrees Celsius, lastly, a plot based on an alternative climate model designated the ‘PCM’ climate model based on a sensitively value of .65 degrees Celsius. To smooth out large monthly variations a 12 month running average is used in all the plots. This information will be shown in four tables and updated each month as the new data comes in.
The first plot, UL is a plot of the NASA temperature anomaly converted to degrees Celsius shown in red with a black trend line added. There has been a very clear reversal in the upward movement of global temperatures since about 2001 and neither the UN IPCC nor anyone else has an explanation for this. Since CO2 has continued to increase at what could be argued an increasing rate this raises serious doubts about the logic programmed into all the IPCC global climate models.
The next plot UR, also in red, shows the IPCC estimates of what the Global temperature should be, based on Hansen’s Scenario B, with the NASA actual temperatures’ subtracted from them. Therefore this plot represents a deviation from what the Climate “believers” think the temperature should be; with a positive value indicating the IPCC values are higher than actual and a negative value indicating the IPCC values are lower than actual. A black trend line is added and we can clearly see that the deviation from expected is increasing at an increasing rate. This makes sense since the IPCC models project increased temperatures based primarily on the increasing level of CO2 in the earth’s atmosphere. Unfortunately, for them, the actual temperatures from NASA are trending down since other factors are in play, therefore each year the gap between them widens. Since we have 12 years of observations’ showing this pattern it becomes hard to justify a continuing belief in the climate models, there is obviously something very wrong.
The next plot LL shown in blue is based on the equations in the PCM climate model described in previous papers and posts here and since it is generated by “equations” a trend line is not needed. As can be seen the PCM, LL, and the NASA, UL, trend plots are very similar the reason being that in the PCM model there is a 68.2 year cycle that moves the trend line up and then down a total of .30 degrees Celsius (.0044 degrees Celsius per year); and we are now in the downward portion of that trend which will continue until around 2035. This short cycle is clearly observed in the raw NASA data in the LOTI table going back to 1880. Because there is also a long trend, 1052.6 years with an up and down of 1.36 degrees Celsius (.0013 degrees Celsius per year) also observed in the NASA data; there is a net cooling of .0031 degrees Celsius per year going up right now. After about 2035 it will reverse and be a net increase of .0057 degrees Celsius. These are all round numbers as both curves are sine curves.
The last plot LR in blue uses the same logic as used in the UR plot, here we use the PCM estimates of what the Global temperature should be with the NASA actual temperatures’ subtracted from them. A positive value indicates the PCM values are higher than actual and a negative value indicates the PCM values are lower than expected. A black trend line was added and it clearly shows that the PCM model is tracking the NASA actual values very closely. In, fact since 1970 the PCM model has rarely been off by more than +/- .1 degrees Celsius and has an average trend of almost zero error, while the IPCC models are erratic and are now approaching an error rate of +.5 degrees above expected.
The IPCC models were designed before a true picture of the world’s climate was understood. During the 1980’s and 1990’s CO2 levels were going up and the world temperature was also going up so there appeared to be correlation and causation. The mistake that was made was looking at only a 20 year period when the real variations in climate move in much longer cycles. Those other cycles can be observed in the NASA data but they were ignored for some reason. By ignoring those trends and focusing only on CO2 the models will be unable to correctly plot global temperatures until they are fixed.
The purpose of this post is to make people aware of the errors inherent in the IPCC models so that they can be corrected.
Sir Karl Raimund Popper (28 July 1902 – 17 September 1994) was an Austrian and British philosopher and a professor at the London School of Economics. He is considered one of the most influential philosophers of science of the 20th century, and he also wrote extensively on social and political philosophy. The following quotes of his apply to this subject.
If we are uncritical we shall always find what we want: we shall look for, and find, confirmations, and we shall look away from, and not see, whatever might be dangerous to our pet theories.
Whenever a theory appears to you as the only possible one, take this as a sign that you have neither understood the theory nor the problem which it was intended to solve.
… (S)cience is one of the very few human activities — perhaps the only one — in which errors are systematically criticized and fairly often, in time, corrected
