New study confirms an alarming warming of the planet

A new study, carried out by Dr. David Parker at the "Hadley Center for Climate Prediction and Research", opposes theories denying the phenomenon of global warming. Skeptics rely on the urban heat island theory, maintaining that the majority of climate readings are carried out near cities, which produce their own heat. For them the global warming recorded in recent years would therefore only be a reflection of urbanization.

However the study commissioned by the British meteorological center (Met Office) and published in Nature, seems to invalidate the theory of the urban heat island. Dr. David Parker used climatic data over the past fifty years to create two graphs: one plotting temperatures on calm nights and the other on windy nights. According to him, admitting the validity of the heat island theory comes down to finding traces of much higher temperatures on calm nights than on windy nights, since the wind blows excess heat out of cities. However, the curves are identical and show an average increase in nighttime temperatures of 0,19 ° C per decade between 1950 and 2000. Dr. Parker adds that the warming of the oceans is another witness to the global warming of the planet.

Eminent specialists such as Myles Allen, a member of the atmospheric physics department at Oxford University, say they are convinced by the Met Office's argument. The American Fred Singer, president of the Science and Environmental Policy Project in Virginia, is a leader of the skeptical movement and defends himself by asserting that only indirect temperature readings should be used to analyze current climate trends. By indirect temperature readings, we mean the study of wood rings, stalactites, fossils, oceanic sediments, etc. He accuses supporters of the global warming theory of being selective in using climate data to show a worrying trend in temperature variations.
