Rains fall during the summer and autumn of 2015 in the states of northeastern and southeastern Australia, as a result of strong tropical storms double their historical average that is 217 mm for the summer, and triple the rains to autum and that in just three hours fell more than 270 mm By midsummer two cyclones affected the states of North and Northwest causing economic damage to infrastructure, housing, transportation, electricity derived from trees.Australia and Oceania do not escape to the effects of climate change that for years has begun to emerge in the region. Climate change is not an isolated phenomenon, and has also appeared in other parts of Asia, Europe, Africa and America, is needed to achieve a joint response to mitigate its consequences.
As a result of climate change the forecast of hurricane activity for the Pacific in 2015 is high. Climate change is characterized by prolonged droughts and heavy rains that alter weather patterns, causing major disasters and floods, rising global temperatures, melting, rising sea levels and increased tropical storm activity and cyclones. Australia is known for its susceptibility to extreme climates and currently presents indicators of extreme and severe drought in different states, with the states of Queensland, South Australia and the Northern Territory which have the largest areas affected by extreme drought indicators.
In early May a strong tropical storm hit the state of Queensland, in just three hours fell more than 270 mm of rain, which caused in the southeast of the state that flooded roads and low areas where people remain trapped on rooftops and automobiles, 5 killed in their vehicles, as well as economic damage and disruption in electricity supply and transport were recorded. Rainfall for autum tripled the historical average of the country that is 80 mm for this season. In February this state was already affected by a tropical cyclone.
After three consecutive days of heavy storms at the end of the second decade of April, winds and floods have forced the evacuation of the population in several towns in New South Wales, some 200,000 homes have been left without electricity, already there are great economic damage. The weather situation became complicated because the winds were accompanied by heavy rainfall which caused flash floods. The town of Dungog has been the most affected by the bad weather, recorded three deaths. The city of Sydney, has been partially insulated, with the main rail links north and south cut, many streets under water. Sydney Harbour the world’s largest coal export has been severely damaged and has been closed until the weather situation improves. Accumulated for the affected region in the period rainfall exceeding 400 mm which is huge when you consider that the average annual rainfall of Australia in the last 10 years is 534 mm.
Australia and Oceania do not escape to the effects of climate change that for years have begun to emerge in the region. Climate change is not an isolated phenomenon, and has also appeared in other parts of Asia, Europe, Africa and America, it is necessary a joint response of different countries in order to mitigate its consequences, the impact of human activity has a great weight in its appearance and requires their control.
