Investigation on the Relation Between the Isolation and Cosmic Radiation and Their effect on Global Warming

Abstract

The amount of heat received on 21 different cities from different countries in Northern and Southern hemisphere were analyzed and modeled .This was made by taking the annual average of temperature from 1998 to 2005 for selected cities in different countries and calculating the area under the temperature year curve This curve was made by using the best polynomial fitting. The rate of change of the temperature was calculated for each city. We found that 9 cities (Doha, Amman, London, Cairo, Abu Dhabi, Muenchen, Muharraq, Kuwait and Muscat) exhibit an increase rate of change in temperature (warming) while four cities (Riyadh, Beijing, Paris, Adelaide) exhibit no change of rate and eight cities (Tokyo, Washington, Tehran, Madrid Budapest, Buenos Aires, Lima and Wellington) exhibit a decrease rate of change in temperature (cooling). The highest negative rate of change (cooling) was in Wellington, New Zealand (-0.0004) and the highest positive rate of change was in London and Doha (+ 0.0003). The amount of heat received by each city during that period was maximum (3120.97 units) in Dhabi, United Arab Emirates, (mean temperature = 28`C) and minimum (959.77) In Muenchen, Germany, (mean temperature = 90C )The sinusoidal temperature - like curves pattern of each city were then compared with the sunspot cycle curve (minimum spots in 1998 of 64 spots, maximum in 2000 of 111 spots and minimum in 2005 of 30 spots) as well as the cosmic radiation curve (maximum flux in 1998 of 6328 counts/min, minimum in 2003 of 5710 counts/min and maximum in 2004-2005 of nearly 6070 counts/min) for the same period. The results show clear evidence of the correlation between these three parameters with more evidence in cities at the northern hemisphere. The solar radiation the sunshine duration and the UV radiation incident on Bahrain was used to support the effect of the above three parameters on the climate change.
