Scientific research has revealed the close relationship between the southwest of Australia's drought and heavy snowfall on the summit of Law Dome, located on the east side of Antarctica, as published by the weekly Nature.
This phenomenon would be caused by an atmospheric circulation model that would be a dry cold wind comes to Australia while the warm, moist air is directed to the Antarctic.For the research, scientists at the Australian Antarctic Division and Research Center Antarctic Climate and Ecosystems comparing rainfall records in the Law Dome and southwestern Australia.
These records have an inverse relationship: the more it rains in a region, the lower the rainfall in the other.
Weather data from Law Dome shows that heavy snowfall in recent decades are unusual when comparedwith the records of the last 750 years, and the same happens in Australia, where drought has been more intense in recent decades in the last 750 years.
The researchers note that the wind flows responsible for these two meteorological phenomena related to climate change induced by human action. Nature published a scientific research in the Australian Antarctic Division and Research Center AntarcticClimate and Ecosystems, which indicates the relationship between the drought experienced by the south-western Australia and snowfall on the summit of Law Dome, Antarctica. The common factor is a model of atmospheric circulation: cold, dry wind that came to Australia and warm moist air that goes to Antarctica.
They compared the record rainfall in these places and the conclusion was that the morerain in one area, less rain falls in the other. Regarding the records of the last 750 years, heavy snow in Low Dome and extreme drought in Australia, are not common. The winds associated with these two meteorological phenomena is due to climate change.
*This was announced today Labour Prime Minister, Julia Gillard, "We will buy the necessary water to farmers willing to sell it to recover thehealth of rivers," Gillard told the ABC radio network.
Of the total, the federal government has spent A $ 1,400 million (1,280 million dollars) to purchase 900,000 million gallons of water to farmers, who buy the rights to the liquid to the state government. Some lawmakers have asked the central executive to take charge of water management to improve management of river resources.
Over ten years ofdrought has dried up much of the lower basin of the Murray and Darling rivers, affecting the natural environment and crops in the southwest.
In 2008, the Government began its program to buy water and, in 2014, hoping that one of every seven gallons of water purchased by farmers for irrigation is returned to rivers.

The drought in Australia threatened its economy and reactivate thenuclear debate

Drought largest Australian history that threatens to criminalize economic boom, causing the ruin of agriculture, revived the debate on the use of nuclear energy and non-country participation in the Kyoto Protocol, the main instrument to combat global warming.

nte this unprecedented drought, which runs the risk of ballasting a historic economic growth,Australian Prime Minister John Howard, announced Monday an increase in aid to farmers in about 210 million euros, bringing the total have for about 960 million euros since the beginning of the drought in 2001.

Analysts believe that the phenomenon could halve this year's wheat production in Australia, third largest producer, less than 11 million tonnes, against 25 million in 2005. The hightemperatures and extensive forest fires in Australia seem to herald a new hot and dry summer.

An enabling environment to revive the debate on global warming, and how the executive Howard addresses this problem. "Can not resolve the long-term crisis of water resources in this country without resolving the crisis of global warming," said the head of the Labor opposition, Kim Beazley.
