The floods in Queensland are being blamed on one of the strongest "La Niña” weather phenomenon case in the world to date that led to unusually less rain to the South America near along the eastern Pacific and more rain to the western Pacific.

This has led to Queensland having its wettest year to date and the country recording its third wettest year on record. La Niña is likely to remain into the southern hemisphere autumn with the possibility of stronger rains says the Australian Bureau of Meteorology. La Niña comes every few years and lasts for about one to two years with its cause largely still a mystery. Experts speculate it stems from the interaction between the ocean and atmosphere.

"This is one of the strongest La Niña events in the past half century," Bill Patzert, a climatologist at Nasa's Jet Propulsion Laboratory told the Guardian. "Impacts include heavy rains and flooding, which has damaged crops and flooded mines in Australia and Asia. It also has resulted in flooding in northern South America and drought conditions in Argentina. "

In Australia, while Queensland has suffered the economic repercussions of La Nina, the unusual weather condition is also addressing the country’s long drought leading to higher water levels in the Murray-Darling Basin from being only 26 percent full at the beginning of last year to being 80 percent full this year.
