A new study by Dr David Parker in "Hadley Centre for Climate Prediction and Research," opposes theories denying the phenomenon of Global warming. Skeptics rely on the theory of island of urban heat, maintaining that the majority of climate statements shall be realized in close to towns, these produce their own heat. For them the planetary warming recorded in recent years is therefore only the reflection of urbanization.
However COMMISSIONED the study by the British meteorological office (Met Office) and published in Nature, seems to invalidate the theory of urban heat island. Dr David Parker uses climate data on the last fifty years to create two graphs: one tracing the temperature quiet nights and one windy nights. According to him, admit the validity of the theory of heat island returns to find traces of much higher temperatures during quiet nights than windy nights, as the wind blows the excess heat out of the cities. However, the curves are identical and show an average increase 0,19.C night temperatures by decade between the 1950 and 2000. Dr Parker added that the warming of the oceans is another witness of the overall Global warming.
On eminent specialists as Myles Allen, a member of the physics department of atmospheric Oxford University, are convinced by the argument of the Met Office. The American Fred Singer, president of the "Science and Environmental Policy Project" Virginia is one of the leaders of the movement of the skeptics and defend by saying that only indirect releves temperatures must be used to analyze current climate trends. By indirect statements shall temperatures, means the study of wooden rings, stalactites, fossils, etc. oceanic sediments He accused supporters of the theory of Global warming to be selective in the use of climate data to show a disquieting tendency of temperature changes
