Evidence of sunspot involvement in
climate change compelling

By Dr Kelvin Kemm

31 Oct 08 – Source: Engineering News - Excerpts – “Over the last few years, the evidence that sunspots on our sun are directly related to climate change on earth has been steadily increasing. Great work in this field is being carried out by Dr Henrik Svensmark and coworkers in Denmark and elsewhere.

“Briefly, the mechanism is that cosmic rays impact on the earth from deep space. These cosmic rays penetrate our atmosphere and lead to the formation of cloud cover. The cosmic rays nucleate sites in the atmosphere, from which clouds form from the natural water vapour.

“The earth’s magnetic field, which acts as a shielding, is altered by the sun’s activity, which, in turn, is indicated by means of the number of sunspots. As the earth’s magnetic shield varies, so the cloud cover varies. Few sunspots mean a weaker earth shield, which means more cosmic rays, which mean more clouds, which mean a cooling earth.

“The correlation for this effect, going back thousands of years, is good, remarkably so.

“In contrast, the argument that man-made carbon dioxide (CO2) is causing warming does not fit the facts at all. Firstly, there was no industrial CO2 produced in vast quantities when the Roman Warming period occurred, or when the Medieval Warming period occurred. Both are well documented in various archives, such as the historical and archaeological.

“Over the last century, the temperature changes in our planet’s atmosphere, let alone ground and sea, just do not match the atmospheric CO2 concentration at all. This is cause for warning bells that, perhaps, this whole CO2 argument is not correct.

“In comparison, the cosmic ray and sunspot information match well.

“Right now, we have been experiencing a rather long period of sunspot inactivity on our sun, some 200 days plus. This has happened before.

“Formal sunspot data collection started in 1749 and has been monitored ever since. But long before that date, sunspots were known and informal measurements were taken. It is, therefore, known that the Little Ice Age, which took place from the mid-seventeenth century to the eighteenth century, was preceded and paralleled by a period of some 50 years with a virtual absence of sunspots, according to informal records.

“In more recent times, we have had relatively long periods without sunspots. This year, we passed the mark of 200 days without sunspots, which is unusual. In fact, the sun has been blanker now than in any other year since 1954, when it was spotless for 241 days, and this year is now being called the sun’s quietest year of the space age.

“The sun was also very quiet in 1913, so runs of 200-plus spotless days are rare, but not that rare. As I have already said, the global warming and cooling issue is complex, and so a run of 200-plus days without sunspots cannot be compared to a 50-year quiet period during the Little Ice Age, but it is cause for some scientific thinking.

“The evidence for sunspot involvement in climate change is just too compelling for it to be brushed aside by those who want to cling to the simplistic idea that man-made CO2 is the only factor.”
