Australia: heatwave is a consequence of climate change caused by man
Southern Australia is experiencing a wave of extreme heat, with the thermometers to exceed 40° c. Despite being summer, abnormal temperatures are causing several fires, the electrical supply failures and even lead to withdrawals of tennis in Australia Open, taking place in Melbourne.Scientists indicate that the wave of extreme heat is a clear example of how climate change caused by human species are having consequences on natural climate variability.According to Sarah Perkins, New South Wales University, a specialist in Australian climate, the latest heatwaves have occurred in the absence of El Ninõ, climatic phenomenon of atmospheric and ocean nature, which causes abnormal warming of surface water and shallow Equatorial Pacific Ocean. "Usually we hope the higher temperatures occur more frequently during the phase of El Ninõ, however, we're checking consecutive heat waves that are not caused by climate variability", says the expert, quoted by the Financial Times.This week, temperatures exceeded 40° C several times and this is the second wave of extreme heat in 15 days. Recently, the Institute of meteorology Australian confirmed that 2013 was the hottest year since annual temperature monitors in the country. Average temperatures were 1.2° C above average long-term, surpassing the record of 2005, when the thermometers were 0.5° C above average.
