LIG (Last Interglacial)

The Last Interglacial (LIG), also known as the Eemian, was a warm period roughly 130,000 to 115,000 years ago when global temperatures were similar to or slightly warmer than today. During this time, sea levels were higher—about 6 to 9 meters (20 to 30 feet) above current levels—due to reduced ice sheets. The LIG provides valuable insights into how Earth's climate and ice sheets respond to warm conditions, helping scientists understand potential future changes related to global warming. It serves as a natural climate analog to study past climate dynamics and sea-level rise.
