Temperatures rise across the ditch

The last 60 years have been the hottest in Australasia for a millennium, most likely thanks to human-caused climate change, a new report says.

Scientists from the University of Melbourne used 27 natural climate records, including tree rings, corals and ice cores to create the first large-scale temperature reconstruction for the region over the past 1000 years.

"Our study revealed that recent warming in a 1000-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," Joelle Gergis, the study's lead researcher, said.

The climate reconstruction was done 3000 different ways, showing with 95 per cent accuracy that there were no other warm periods in the past 1000 years that matched or exceeded post-1950 warming observed in Australasia.
