It’s not drought, it’s climate change, say scientists

The Age

…But to see what role greenhouse gases played in the recent intensification, the scientists used sophisticated American computer climate models.

When they ran simulations with only the ”natural” influences on temperature, such as changing levels of solar activity, they found there was no intensification of the subtropical ridge and no decline in rainfall.

But when they added human influences, such as greenhouse gases, aerosols and ozone depletion, the models mimicked what has occurred in south-east Australia – the high pressure systems strengthened, causing a significant drop in rainfall.

”It’s reasonable to say that a lot of the current drought of the last 12 to 13 years is due to ongoing global warming,” said the bureau’s Bertrand Timbal.

”In the minds of a lot of people, the rainfall we had in the 1950s, 1960s and 1970s was a benchmark. A lot of our [water and agriculture] planning was done during that time. But we are just not going to have that sort of good rain again as long as the system is warming up.”…

Just a little over a year later (December 2010), the devastating Queensland floods hit and more recently (March 2012), parts of Victoria, the Northern Territory and almost three quarters of NSW are affected by floods.

Now that’s what you call a wash-out of a prediction and yet they say they can predict the climate in 100 years time!
