A new study confirms a disquieting Global warming

A new study, carried out by Dr. David Parker at the Hadley Center for Climate Prediction and Research, is opposed to theories denying the global warming phenomenon. The skeptics rely on the theory of the urban heat island, maintaining that the majority of climatic readings are carried out near towns, which generate their own heat. For them, global warming in recent years is only a 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.

Eminent specialists such as Myles Allen, a member of the department of atmospheric physics at Oxford University, are convinced by the Met Office's argument. American scientist Fred Singer, president of the Science and Environmental Policy Project in Virginia, is one of the leaders of the skeptics movement and defends himself by stating that only indirect temperature records should be used to analyze current climate trends. Indirect temperature readings include the study of wood rings, stalactites, fossils, oceanic sediments, etc. He accuses advocates of the global warming theory of being selective in the use of climate data to show a disturbing trend of temperature fluctuations
