Introductory discussion.

Point 1.1: Global Warming has halted

Global mean temperature rose continuously from 1800-1850. The rate of increase was .05 degrees Celsius per 100 years. This was mostly unrelated to CO2 gas (CO2 began to increase suddenly after 1946. Until the sudden increase, the CO2 emissions rate had been almost unchanged for 100 years). However, since 2001, this increase halted. Despite this, CO2 emissions are still increasing.

According to the IPCC panel, global atmospheric temperatures should continue to rise, so it is very likely that the hypothesis that the majority of global warming can be ascribed to the Greenhouse Effect is mistaken. There is no prediction of this halt in global warming in IPCC simulations. The halt of the increase in temperature, and slight downward trend is "something greater than the Greenhouse Effect," but it is in effect. What that "something" is, is natural variability.

From this author's research into natural (CO2 emissions unrelated to human activity) climate change over the past 1000 years, it can be asserted that the global temperature increase up to today is primarily recovery from the "Little Ice Age" earth experienced from 1400 through 1800 (i.e. global warming rate of change=0.5℃/100).

The recovery in temperatures since follows a naturally variable 30-50 year cycle, (quasi-periodic variations), and in addition, this cycle has been positive since 1975, and peaked in the year 2000. This quasi-periodic cycle has passed its peak and has begun to turn negative.

(The IPCC ascribes the positive change since 1975, for the most part, to CO2 and the Greenhouse Effect.) This quasi-periodic cycle fluctuates 0.1 degrees C per 10 years, short term (on the order of 50 years). This quasi-periodic cycle's amplitude is extremely pronounced in the Arctic Circle , so it is easy to understand. The previous quasi-periodic cycle was positive from 1910 to 1940 and negative from 1940 to 1975 (despite CO2 emissions rapid increase after 1946).

Regardless of whether or not the IPCC has sufficiently researched natural variations, they claim that CO2 has increased particularly since 1975. Consequently, after 2000, although it should have continued to rise, atmospheric temperature stabilised completely (despite CO2 emissions continuing to increase). Since 1975 the chances of increase in natural variability (mainly quasiperiodic vibration) are high; moreover, the quasiperiodic vibration has turned negative. For that reason, in 2000 Global Warming stopped, after that, the negative cycle will probably continue.

Regarding the current temporary condition (la Nina) JPL observes a fluctuation of the quasiperiodic cycle [JSER editor's note: this book is is still being proofed as of 12/19]. So we should be cautious, IPCC's theory that atmospheric temperature has risen since 2000 in correspondence with CO2 is nothing but a hypothesis.

They should have verified this hypothesis by supercomputer, but before anyone noticed, this hypothesis has been substituted for "truth". This truth is not observationally accurate testimony. This is sidestepping of global warming theory with quick and easy answers, so the opinion that a great disaster will really happen must be broken.

It seems that global warming and the halting of the temperature rise are related to solar activity. Currently, the sun is "hibernating". The end of Sunspot Cycle 23 is already two years late: the cycle should have started in 2007, yet in January 2008 only one sunspot appeared in the sun's northern hemisphere, after that, they vanished completely (new sunspots have now begun to appear in the northern hemisphere). At the current time, it can clearly be seen there are no spots in the photosphere. Lately, solar winds are at their lowest levels in 50 years. Cycle 24 is overdue, and this is is worrisome.

So, have there been other historical periods with an absence of sunspots? As a matter of fact, from 1650 to 1700 approximately, there were almost no sunspots. This time period has been named for the renown English astronomer Maunder, and is called the Maunder Minimum.

There is a relationship between transported energy and the light emissions from the photosphere and sunspots. It was thought that times of few sunspots are times of lower energy. Satellites were launched in 1980 to research this, and results were contrary to expectations. It became clear that these times were more energetic than periods of high sunspots. Periods of low sunspots have vigorous solar activity. The total change during sunspot cycles is usually .0.1%, from the Maunder Minimum to today the increase is .05%. The Maunder Minimum fell in the middle of the period of 1400-1800, the Little Ice Age, and it was theorized that this was due to a cut in solar emissions. The theory is that solar activity began to increase after that, and from 1800 global warming increased and recovery from the Little Ice Age began.

But sunspot change and climate change are not clearly correlated. Rather, the cycle was not the punctual 11 years, scientific research indicates that climate change is related to that change. Furthermore, according to the IPCC's computational investigation, this energy increase does not significantly contribute to global warming. But then, the IPCC insists that current global warming correlates to CO2, solar influence is estimated as minimal, this calculation should be redone. This 0.1-0.5% is an enormous sum of energy. The energy of solar emissions is not just light from the photosphere. Solar winds cause geomagnetic storms, yet comparisons of solar wind and light energy to particle emissions are rarely carried out. Research into the relationship between geomagnetic storms and climate change has been undertaken for almost 100 years. However, because during this time, this simple correlation has not been seen, no conclusion has been reached. The super-hot temperatures of geomagnetic storms higher than 100 kilometers have increased, and the chances of the stratospheric and tropospheric transference are low.

Through the 11 year sunspot cycle, ultraviolet rays vary considerably, the ionosphere and ozone layer are affected. Whether or not this affects the troposphere is unknown. More research is necessary. On the other hand, cosmic rays continuously fall, it seems that they constantly seed comparatively low clouds. The solar system may shield us somewhat from Geomagnetic storms caused by solar winds, so called "magnetic clouds" may shield us from extrasolar cosmic rays, so solar activity and climate are in a complex relationship.

In this way, climate change and solar activity's relationship is inconclusive. It is necessary to increase research efforts into the relationship between Earth's climate fluctuations and solar activity.
