Global warming is being cooled by the sun. The sun has been spotless for over a month. This indicates a trend towards a cooling of the Earth. So it seems this global warming is a myth. Sunspot activity has a much stronger influence on the Earth’s climate than greenhouse gases. The higher the sunspot activity, the more solar energy fuels Earth’s atmospheric circulation and warms the Earth.
Our Present climate is reminiscent of the Little Ice Age, which lasted from the 14th century to the mid 19th century. This period had two minimums of sunspot activity, was colder than normal and experienced unpredictable weather patterns. During this period the year 1816 is known as the year without summer. This Little Ice Age followed the Medieval Warm Period, which lasted, from 950 to 1100, when the Vikings explored areas, which today are too cold to be inhabitable. Incidentally, this warm time was preceded by a cooler period, the Dark Ages Cold Period, from the fall of the Roman Empire in the mid 5th century to about 900.
Fluctuations and climate warming is nothing new to the Earth. One cause for our present warming is recent sunspot activity. During the last 70 years the sunspot activity, and hence energy from the Sun, has been unusually high. The previous period of similar sunspot activity was approximately 8000 years ago.
The number of sunspots has been found to correlate with the intensity of solar radiation over the period, 1979 to the present, when satellite measurements of radiation are available.
This year the number of sunspots has averaged 3 per month against 50 to 100, which has been the norm for the first half of this decade. Now August bottomed out with zero sunspots.
In his book The Chilling Stars: The New Theory of Climate Change, the author and physicist Henrik Svensmark explains how galactic cosmic rays, increase the formation of molecular clusters that promote cloud growth. The sun's magnetic field partially shields the Earth from these galactic cosmic rays, although the correlation between clouds and cosmic rays is complex. This relationship is a larger factor in climate change than greenhouse gases.
In the late 60s the talk was about a coming ice age. It appears that is still on the cards. Global Warming is on hold. Victor Manuel Velasco Herrera, a researcher at the National Autonomous University of Mexico's Institute of Geophysics predicts there will be a global cooling in two years, which will last 60 to 80 years.
So don’t get rid of the winter woollies yet. Today’s global warming hysteria is already yesterday's news.
