Hidden deep underground in Indonesian caves, the missing link in the
demise of the last ice age has been uncovered in stalagmites, which have
provided a 31,000 year-long record of Australasian monsoon activity.
“Stalagmites are the ice core records of the tropics,” explains Dr
Linda Ayliffe from the Research School of Earth Sciences (RSES).
“They are the only natural climate archive with the length,
resolution and age-control required to document the response of the
Australasian monsoon to abrupt climate change over tens of thousands of
years.”
The global monsoon system is considered to be an important climate
link between the northern and southern hemispheres during the
deglaciation of the last ice age. Until now, direct evidence for the
southern half of the vast Australasian monsoon has been lacking. [...] news.anu.edu.au
