While we grapple with the impact of climate change, archaeologists
suggest we spare a thought for Aboriginal Australians who had to cope
with the last ice age.
"The period scientists call the Last Glacial Maximum, or LGM for
short, is the most significant climatic event ever faced by humans on
this continent," Associate Professor Sean Ulm from James Cook University
in Cairns said.
Research recently published in the Journal of Archaeological Science sheds
new light on the ways Aboriginal civilisation met the challenges of
extreme climate change during the Last Glacial Maximum, which peaked
around 20,000 years ago.
"The magnitude of change was phenomenal," said Professor Ulm, a lead
researcher on the project and Deputy Director of JCU's Centre for
Tropical Environmental and Sustainability Science.
"Lakes dried up, forests disappeared, deserts expanded, animals went
extinct and vast swathes of the Australian land mass would have been
simply uninhabitable." [...] sciencedaily.com/
