Australian scientists have discovered a lake that has been untouched by climate change for the past 7,500 years.
Blue Lake, off the southern coast of Queensland, has been studied by a team of researchers who've found that the body of water has been in the same chemical state for thousands of years. Cameron Barr, of the University of Adelaide, and his team studied Blue Lake’s discharge, water quality, fossil pollen and algae and found that the lake is unaffected by climate change.
"It's like God's bathtub," Barr told the Australian Associated Press. "It is beautiful. It is absolutely beautiful."
What accounts for the Blue Lake’s pristine condition? Location. It's situated on North Stradbroke Island, a sand island. The lake drains out in a nearby swamp and its water gets replaced by an aquifer every 35 days.
“Because it’s constantly being updated, it doesn’t suffer from the vagaries of the climate in so far as it doesn’t evaporate and become more saline,” Barr said.
News of Blue Lake’s “godly” state came as a surprise for researchers.
"We didn't realize just how unique and unusual this lake is until we started looking at a wide range of environmental markers," Barr told the Australian. Besides the chemical samples, scientists also studied photos taken of the lake over the past 117 years.
Barr notes that despite climate change factors the region has experienced in recent decades, Blue Lake showed “little variation” in its shoreline and water chemistry. In fact, Barr believes that Blue Lake will continue to remain unspoiled by man.
"With appropriate management, the lake could continue relatively unchanged for hundreds, possibly thousands of years to come," he said.
