global warming could be behind the floods that ravage northeastern Australia scientists say University of New South Wales (Sydney) and the United States
Although global warming is a phenomenon that occurs on a global scale and that, therefore, be assessed and investigated within the same broad context (time and space), it is also true that specific events are occurring that can hardly be explained by its size and uniqueness, without layering it. Not in vain scientists and anticipated that one of the worst consequences of rising global temperatures would be more extreme weather, including severe flooding in some areas and prolonged periods of drought in others.
For this reason, scientists the Research Centre on Climate Change at the University of New South Wales in Sydney have been quick to link the unprecedented intensity of the rains that are suffering in the country with the climate change phenomenon. Matthew England, a member of the research center, explains that "rains in Australia are the hottest ever have been measured, and this water provides moisture to the atmosphere to the monsoon Queensland and northern Australia ", noting also that we still expect more showers and thunderstorms.
CHILD AND THE GIRL
Heavy rains have shown follow one of the patterns La Niña strongest on record. The phenomenon known as 'La Nina' is a cooling of ocean temperatures in the eastern and central Pacific, which typically causes more rain in Australia, Indonesia and parts of Southeast Asia. This phenomenon causes the appearance of easterly winds in the tropics collide with the warm waters of the western Pacific and Australia. Indonesia said Wednesday it expects the rainy season lasts through June.
chief of climate monitoring and prediction Bureau of Meteorology of Australia, David Jones , stated that have always been affected by El Niño and have natural variations, "but the formations that are acting now are different" . "The first thing we can say 'La Nina' and 'El Niño' is taking place in a warmer world" Jones said, adding that this situation will cause greater water evaporation, more moisture in the atmosphere and worst weather forecast.
"In this way, it is expected that the drought of El Nino more heavy rains as 'La Nina' " said, but added it would be several years until you see the real impacts of climate change. Jones said 'The Girl' This year is different ocean temperatures that are hotter and have reached records in Australia, and the high humidity in the east of the country during the past 12 months.
COMBINATION OF FACTORS
American scientist climate change expert Kevin Trenberth also said that flooding and the intensity of 'La Niña' was due to a combination of factors such as high temperatures in the Indian Ocean near Indonesia and the rapid onset of 'the girl' after the end of 'El Niño' in May. "The rapid onset of 'La Niña' led to a greater intensity of the monsoon in Asia and the rise of one degree Fahrenheit in ocean temperatures caused surface flooding in India and China in July and Pakistan in August" , Trenberth said.
Rising ocean temperatures in northern Australia, 1.5 degrees with respect to levels before 1870, could be attributed to climate change. "The extra water vapor gives strength to the monsoon and this alters the winds and the monsoon in themselves, so this increases the rains ", said the head of the Climate Analysis Section National Center for Atmospheric Research in Boulder, Colorado. " So is easy to conclude that an abnormality in one degree centigrade at temperatures of sea surface increases by 10 to 15 percent rainfall " he added.
EXCEPT THOSE
Anyway there are still some scientists who do not believe these phenomena are related to climate change. For example, the president of the Society of Meteorology and Oceanography in Australia, Neville Nicholls, who believes that these rains are just a "natural phenomenon" and there are no reasons for "this 'girl' is stronger than it would be without humans" . Should remind Mr Neville that the rising temperatures is not happening in a parallel universe or speculative, but here and now, and it is curious that there are still people who consider and argue that scientific evidence is indisputable as the temperature increases global average does not have any consequences or effects on the climate on the planet.
