A prolonged dry spell in Indonesia thousands of years ago has been found to correlate with ice ages in the northern hemisphere. Brown researchers have compiled a detailed Indonesian climate record of the last 60,000 years, tracking telltale indicators in sedimentary cores: titanium levels (a marker for surface water runoff) and the carbon isotopes of leaf wax, a marker for plant varieties (grasses indicate dry conditions).
