By studying climate changes that took place thousands of years ago, we can better understand the global climate system and predict the Earth’s future climate. A multi-organization research team led by Professor HYODO Masayuki (Research Center for Inland Seas, Kobe University) has discovered evidence of rapid climate changes on a millennial-to-centennial scale that occurred 780 to 760 thousand years ago. The findings were published on August 30 in Scientific Reports.
