Sunspots have usually a diameter of about 37,00km and appear as dark spots within the photosphere. There is a strong radial magnetic field within a sunspot. There is an even better correlation with the length of the solar cycle, between years of the highest numbers of sunspots. Recent research shows that the combined effects of sunspot-induced changes in solar irradiance and increases in atmospheric greenhouse gases offer the best explanation for the observed rise in average global temperature over the last century. The Earth’s climate is always changing. The Sun is the source of the energy that causes the motion of the atmosphere and thereby controls weather and climate. “During stable conditions there has to be a balance between the energy received from the sun and the energy that the earth radiates back into space.” The climate changes prior to the industrial era may be strongly influenced by variations in solar activity. As hot as the earth was getting the sun was still cooling. It shows that the green house egasses have played a bigger effect on the earth’s climate, more than the sun’s activity. Although sunspots themselves produce only minor effects on solar emissions, the magnetic activity that accompanies the sunspots can produce dramatic changes in the ultraviolet and soft x-ray emission levels.Uniformitarianism and Catastrophism are two concepts are on the same subject but have two very different view points. In the mid-seventeenth century, biblical scholar and Archbishop James Ussher determined that the earth had been created in the year 4004 BCE. Just over a century later James Hutton, known as the father of geology, suggested that the earth was much older and that processes occurring in the present were the same processes that had operated in the past, and would be the processes that operate in the future. Hutton based the theory of uniformitarianism on the slow, natural processes that he observed on the landscape. He realized that, if given enough...
