A Forecast Of Global Cooing For The Remainder Of The Century


Dr. Norman Page believes that natural cycles of 60 and 1,000 years are the principle drivers of Global climate.  He has recently published a study relating his beliefs.  From that study  “The coming cooling: usefully accurate forecasting for policy makers” I will begin with one of his charts:

Here Dr. Page compares forecasts by the IPCC, another forecaster S. Akasofu and his own.  The IPCC  forecast which you have probably seen many time predicts a global temperature rise of 4C by 2100.  Akasofu is much below the IPCC forecast at about 1C by 2100.  Page’s forecast is for a reduction in global temperature by the year 2100.

Dr Page’s Abstract to this paper lays out the big picture:

“ABSTRACT

This paper argues that the methods used by the establishment climate science community are not fit for purpose and that a new forecasting paradigm should be adopted. Earth’s climate is the result of resonances and beats between various quasi-cyclic processes of varying wavelengths. It is not possible to forecast the future unless we have a good understanding of where the earth is in time in relation to the current phases of those different interacting natural quasi periodicities. Evidence is presented specifying the timing and amplitude of the natural 60+/- year and, more importantly, 1,000 year periodicities (observed emergent behaviors) that are so obvious in the temperature record. Data related to the solar climate driver is discussed and the solar cycle 22 low in the neutron count (high solar activity) in 1991 is identified as a solar activity millennial peak and  correlated with the millennial peak -inversion point – in the RSS temperature trend in about 2004. The cyclic trends are projected forward and predict a probable general temperature decline in the coming decades and centuries. Estimates of the timing and amplitude of the coming cooling are made. If the real climate outcomes follow a trend which approaches the near term forecasts of this working hypothesis, the divergence between the IPCC forecasts and those projected by this paper will be so large by 2021 as to make the current, supposedly actionable, level of confidence in the IPCC forecasts untenable.”

The four basic trends in play here according to Page:

“To summarize, the forecasts which follow rely on four basic working hypotheses. First, the solar millennial activity cycle peaked in 1991+/- as seen in Fig 10 in the Oulu neutron count. Second, the corresponding millennial temperature cycle peaked in the RSS data at about 2004-Fig. 4.Third, the 60 year temperature cycle peaked at about the same time and fourth, Ockham’s razor would suggest that the simplest working hypothesis currently available, based on the weight of all the data, is that the trends from the 990 Millennial peak to the 2004 Millennial cycle peak seen in Figs 3 and 4 will, in general, repeat from 2004 to 3004.”

Those charts are as follows:

Figure 10 has had some enhancements so I am showing you that chart.  Note how the cosmic ray theory/clouds cooling are illustrated.

 

Fig 4. RSS trends showing the millennial cycle temperature peak at about 2003.6 (14)

Figure 4 illustrates the working hypothesis that for this RSS time series the peak of the Millennial cycle, a very important “golden spike”, can be designated at 2003.6.

Good view of the 1000 year cycle that Page refers to.

Dr. Page also predicts the next Little Ice Age  will likely occur about 2640+/-

Page’s  study is about 15 pages long but is definitely  worth your time to read it.

Russian Scientists Suggest Global Temperatures Will Drop


There are two recent papers indicating that global cooling will begin soon.    Both studies believe that more cosmic rays in the Earth’s atmosphere will be responsible for reduced global temperatures. The cosmic rays produce lower level clouds which reduce temperatures by reflecting incoming solar radiation back into space.

 

“Cosmic Rays, Solar Activity, and Changes in the Earth’ Climate is by a group of Russian scientists led by Y.I. Stozhkov.  The Paper considers Milankovich theory on global temperatures but dismiss it for this study saying that “…… (Milankovitch) changes happen on a long -term scales and are unlikely to be related to the contemporary process of global warming.”  The three orbital factors in this theory are:

  • the Earth’s orbital eccentricity which changes or 100,000 to 400,000 years
  • the tilt angle of the Earth’s rotational axis which has about a 41,000-year cycle
  • the precession angle changes with periods of 19,000 to 26,000 years

They considered solar luminosity but feel that the changes in total solar irradiation (TSI) are too small to alter average global temperature by no more than 0.05C.

The study also looked at the cosmic  rays.  The team compiled  monthly Δ T* data for the period from 1880 to early 2016.  Using that data, they made a spectral analysis for the same period.  The result is shown on the chart below:     (*Δ T often called the “temperature anomaly”.)

The team looked at cosmic rays versus Δ T and found a relationship.  Cloud formation is a function of cosmic ray presence in the Earth’s atmosphere. That is illustrated from the team’s chart shown below:

The team interestingly does not attribute cosmic ray intensity in the Earth’s atmosphere to solar activity.  The study reports:

“Another influence on the Earth’s climate is solar activity; the main period of its variations is ≅11 years. Despite numerous attempts to find a connection between different solar activity indices and temporal variations in delta T values, no such link has been firmly established.”

Their contribution is —-an increase in cosmic rays in the Earth’s atmosphere will lower global temperature. Thus, leaving the reason the cosmic rays increase or decrease as an unknown. Their Figure 1 seems to suggest they see a drop in global temperature beginning soon and lasting until at least 2060.

 

The second study will be posted next.

Solar Cycle 24 February Update And Some Thoughts On Cycle 25.


There were no visible Sunspots on 11 March 2017.  There was but one Sunspot cluster showing on 12 March.  This will become more common as Solar Cycle continues on its way to its demise and the beginning of Cycle 25.  From Wiki, we get the record of The “Spotless days at the end of the cycle”.   These numbers have been recorded since Cycle 9 that ended in March 1855.  The recent “grand maximum” beginning with Cycle 18 thru Cycle 22 provides us with these numbers:

Cycle Start/Finish Max sunspots Sunspotless days-end of cycle
18 Jan44/Feb54 151.8 446
19 Feb54/Oct64 201.3 227
20 Oct64/May76 110.6 272
21 May76/Mar86 164.5 273
22 Mar86/Jun96 158.5 309
23 Jun96/Jan08 120.8 817
24 Jan08/   ?   81.9 (Apr14) ?

 

Cycle 24 has been much less active than its recent predecessors. It was ushered in following 817 spotless days.  This appears to be significant but we probably need to see how this plays out at the end of Cycle 24 and its effect on Cycle 25.

The current, seemingly, most used way to predict the size of Cycle 25 is examining the Solar Polar Field Strength of Cycle 24.  As noted in previous postings the technique is to examine the average field strength after the Maximum occurs.  Typically, it levels out.  The average field strength is computed by adding North and South field strengths and dividing by 2.  Below is a plot of the field strength for Cycles 21,22,23 and 24. Looking at the left

plot, so far the Cycle 24 average is about 50. The high point for Cycle 23 looks to have been about 70. This suggests that Cycle25 will be smaller than 24.  But Cycle 24 average field strength of  nominally about 50, could become larger over the next year. So again, we will have to wait and see.

(Unfortunately, the expanded left chart is unavailable.An  expanded left chart was put in this posting but it was too large to show the period of the Cycle 23 and 24.)

 

Below is the February 2017 Cycle 24 chart comparing it to Cycle 23.

CO2 And Climate Change Science–Part 2: A Summary Of The Science


The website CO2 Coalition has a post titled “Climate Change: A summary of the Science”.  It one of the best summaries I have come across lately.  It is fairly long, so I could do my usual and summarize it, but there is virtually nothing in it that I would want to skip over.  So, I will not deprive the reader. I will put it in, in its entirety.  I hope that my posting yesterday will fill in any blanks you may have otherwise had.

CO2 And Climate Change Science–Part 1 Carbon Cycle


This posting sets out a preliminary understanding of the “carbon cycle” that you may not be aware of. The next posting will build off of this to lay out the science of climate change.

The Sun is the Earth’s source of energy. The energy is transported in the form of waves (radiant energy) known as electromagnetic energy. The Sun’s enormous surface temperatures generates these waves. The waves have a wide range of frequencies. In general, the waves are known familiarly as x rays, ultraviolet, sunlight, short wave infrared, radio waves, and microwaves. These waves heat the Earth.  Not all of the waves get through to the Earth’s surface.  Some are absorbed like Ultraviolet by ozone;  some are reflected back into space by clouds; and some are scattered by encountering mater in the atmosphere.

Much of the  Suns energy is reemitted from the Earth as longwave infrared. Some of the reemitted energy is delayed on its way back out into space by the so called greenhouse gases and water vapor. This slowdown is the reason the Earth has a habitable temperature. The primary greenhouse gas is carbon dioxide (CO2).  However, water vapor is the largest factor, by far, in the greenhouse effect.

CERN CLOUD Study Says IPCC Climate Sensitivity Is Too High.  Svensmark Vindicated Some What.


Water vapor is acknowledged to be the primary “greenhouse gas”.  In the warmer’s theory, any increase of global temperature due to atmospheric CO2, results in a corresponding increase of water vapor.  The impact on temperature is a tripling of that which would occur from CO2 alone. This feedback loop is called Climate Sensitivity.

Climate Sensitivity

Actual temperature records show that this is not happening.  There has been only a slight rise in global temperatures over the past 20 years and that rise may have been from natural causes rather than CO2. See this argument in this posting. The most recent IPCC global warming report was ambiguous on this issue, apparently recognizing that their long held standard 3X increase was in trouble. Studies by many groups have demonstrated the multiplier is not 3X and at least 2X at best.  See the following chart:

German Solar Scientists Say Solar Cycle 25 Will Look Like Cycle 24.


German solar scientists, Frank Bosse and Fritz Vahrenholt say that Solar Cycle 24 is the “..third weakest cycle since observations began in 1755.”  The Accumulated Sunspot Anomaly until 97 months after cycle start is shown on the figure below:

Figure 2: Comparison of all the solar cycles.  The chart shows the accumulated sunspot number anomaly from the mean value.

The mean value is noted at zero and Cycle 24 is running 3817 spots less than the mean and only two other Cycle had fewer.    Note that the seven Cycles that preceded Cycle 24 had more sunspots than the mean.
