CRU Information Sheet no. 2: The Causes of Climatic Change
Earth's climate? Despite many studies, the evidence is still controversial. Sunspot cycles have been found in climate parameters, but the fluctuations are weak and tend to ... -term fluctuations have also been linked to climatic change. In the early 1600s, the sunspot cycle almost disappeared and this phenomenon, the so-called Maunder Minimum, has been associated with the ...

Controversy
CFC's? S.F.Singer argues No for the following reasons- Insufficient experimentation or observation to show that the current downward trend is not due to natural factors, such as the 11year sunspot cycle. Singer does acknowledge that there is sufficient data to show that CFC's are the major cause of ozone depletion ...

We now know that what reaches the Earth rises and falls in step with the eleven-year sunspot cycle, such that today--near the minimum of the cycle--we receive about 0.1 percent less heat and light than in years when sunspots are plentiful. The cause is a systematic variation in brightness from place to place on the surface ...

Climatology
The Sun's brightness varies enough to effect climate. The Sun's 11 and 22 year sunspot cycle is well known. Sunspots have been observed for thousands of years. Apparently there were no sunspots ... sudden. There are many examples of metastability. The El Nio Southern Oscillation is one; the monsoon cycle of India is another. [4] Climate exhibits negative and positive feedback Here is an example of ...

NGDC/STP - Sunspot Numbers
Wolf chose to compute his sunspot number by adding 10 times the number of groups to the total count of individual spots, ... to be 11.1 years by using early historical records. Wolf, who became director of the Zurich Observatory, discovered independently the coincidence of the sunspot cycle with disturbances in the earth's magnetic field. How Sunspot ...

I guess we'll start with the auroras that occurred here on July 26th. Auroras can occur at any time of the year, but are more frequent near the peak of the 11-year sunspot cycle. We are past the peak now by a few years, but every once in a while things just work out right. In order to see ...

DayCreek Journal - November 11, 2001
At our latitude the best time to see the northern lights is during the peak of the 11-year sunspot cycle. Although we are past the maximum, the sun is still quite active. There is also a greater chance to see the lights in the spring and autumn seasons. Of course, the weather needs to cooperate too. Everything came ...
