eThe phrase global warming refers to the documented historical warming of the Earth's surface based upon worldwide temperature records that have been maintained by humans since the 1880s.It is the increase in the average temperature of the Earth's near-surface air and oceans.In the last 100 years, this temperature increased by about 0.8 °C (1.4 °F) with about two thirds of the increase occurring over just the last three decades.According to the exponentss of the concept,the likely effects of a further warming at the same rate include a rise in sea levels,change in the amount and pattern of precipitation,a probable expansion of subtropical deserts,more frequent occurrence of extreme weather events including heatwaves, droughts and heavy rainfall events, species extinctions due to shifting temperature regimes and changes in agricultural yields.Although there has been a controversy, significantly more pronounced in the popular media than in the scientific literature,regarding the nature, causes, and consequences of global warmin,there is a strong consensus in the scientific literature that global surface temperatures have increased in recent decades and that the trend is caused mainly by human-induced emissions of greenhouse gases. No scientific body of national or international standing disagrees with this view,though a few organisations hold non-committal positions

while the proponents of global warming strongly believe that it is a result of human activities,its skeptics argue that natural climate fluctuation, not human activity, is responsible for the past century’s rising temperatures. According to S. Fred Singer, a former professor of environmental sciences at the University of Virginia, the earth’s climate has never been steady and has continually warmed and cooled over the course of geologic time without any assistance from human activity. According to him the human component [in recent global warming] is thought to be quite small and the climate rather cooled between 1940 and 1975, just as industrial activity grew rapidly after WWII. It has been difficult to reconcile this cooling with the observed increases in greenhouse gases.Singer also argues that temperature observations since 1979 are in dispute coz surface readings with thermometers show a rise of about 0.1 degree C per decade, while data from satellites and balloon-borne radiosondes [miniature transmitters] show no warming—with possible indications of a slight cooling—in the lower atmosphere between 1979 and 1997. Until the science behind the global warming theory is more settled, Singer and other skeptical scientists advocate placing no limits on the consumption of fossil fuels.

Likewise,the skeptics of global warming call the historical record of atmospheric carbon dioxide concentrations claimed by the IntergovernmentalPanel on Climate Change (IPCC) , a fraud. Research by a Freiburg, Germany professor, Ernst-Georg Beck shows that the IPCC construed and concocted the pre-1957 CO2 record from measurements on recently drilled ice cores, ignoring more than 90,000 direct measurements by chemical methods from 1857 to1957.The IPCC’s hoked-up record attempts to prove that CO2 concentrations have been steadily increasing with the progress of human industrial civilization. Beck’s work confirms a wealth of previous investigations which demonstrate that the IPCC cherry picked its data in an attempt to prove that we must stop industrial development and return to the horse-and-buggy age, or face oppressive heat and melting of the polar ice caps. It also shows that the Kyoto Treaty on reduction of greenhouse gases was based on a scientific fraud which violates the laws of the universe, denying the well-established determination of climate by cyclical variations in the Earth-Sun orbital relationship and in the Sun’s heat output.In a thorough review of 175 scientific papers,Professor Beck found that the founders of modern greenhouse theory had completely ignored...
