How are the Australian skeptics going to spin this one?




Last 60 years hottest in a millenium in Australasia (that would be 1000 years)

Australasia has hottest 60 years in a millennium, scientists find

Study of tree rings, corals and ice cores find unnatural spike in
temperatures that lines up with manmade climate change

Opening paragraphs:
"The last 60 years have been the hottest in Australasia for a millennium and cannot be explained by natural causes, according to a new report by scientists that supports the case for a reduction in manmade carbon emissions.

In the first major study of its kind in the region, scientists at the University of Melbourne used natural data from 27 climate indicators, including tree rings, corals and ice cores to map temperature trends over the past 1,000 years.

"Our study revealed that recent warming in a 1,000-year context is highly unusual and cannot be explained by natural factors alone, suggesting a strong influence of human-caused climate change in the Australasian region," said the study's lead researcher, Dr Joelle Gergis.

The climate reconstruction was done in 3,000 different ways and concluded with 95% accuracy that no other period in the past 1,000 years match or exceeded post-1950 warming in Australia."



And here's the plot of record;  is this an "Aussie Rules" hockey stick?
