Nasty one for the "extreme weather" cries of the Warmists

Like the Southern USA, Northern Australia has a lot of very severe wind events -- called hurricanes in the USA and cyclones in Australia. So Northern Australia is a prime place for detecting an increase in "extreme" weather. But it isn't happening. So how do the Warmists respond? Not in a scientific way by deferring to the facts but by saying that extreme weather is like the second coming of Christ or the collapse of capitalism: It will happen "one day"

AUSTRALIAN government climate experts have failed to detect an increase in the intensity of tropical cyclones after analysing 26 years of data since the early 1980s. Climate scientists have warned that Australia should expect to see more intense cyclones in the future fuelled by rising global temperatures caused by greenhouse gases. But this latest research from seven Bureau of Meteorology scientists shows that so far there is no conclusive evidence to suggest this is already happening.

Scientists told The Courier-Mail the findings, which will fuel the debate among skeptics of human-caused climate change, did not mean climate change would not cause an increase in the frequency of powerful cyclones in the future.

Appearing in the prestigious Journal of Geophysical Research Atmospheres, published by the American Geophysical Union, the scientific paper analysed satellite data and images for all the tropical cyclone seasons in Australia from 1981 to 2007. The research concluded: "In the Australia region, no significant trends in the total numbers of Tropical Cyclones, or in the proportion of the most intense TCs, have been found."

Co-author of the research, Dr John McBride, said: "We still expect more intense cyclones but we are comfortable with the fact that you cannot yet see that in the data." The research did find a positive trend in the numbers of the most intense cyclones in the Southern Indian Ocean region. But the authors said while it was "possible" that the trend could show climate change at work, this finding could instead be down to "changes in data quality".

In theory, scientists say ongoing rises in ocean temperatures should see the numbers of intense cyclones increase. Professor David Karoly, a world-leading climatologist at the University of Melbourne, said the research did not change this expectation. "It's very very difficult with a 20 or 30-year time scale to separate a climate change signal from natural variation. You would not expect to see a signal until about 2030."

Last week Opposition Leader Tony Abbott criticised the Government's proposed emissions trading scheme, saying it should "not politicise events such as floods or cyclones to try to justify a new tax."
