Younger Dryas event and global meltwater pulses reshaping Earth. The Younger Dryas (12,000-11,600 years ago) was a reshaping of Earth's surface as extreme as any in the last 5 million years The Eemian stage (116,000-130,000 years ago) was warmer than current Holocene with sea levels 20 feet higher Meltwater pulse 1B occurred at 11,600 years ago

The Younger Dryas period (12,900-11,600 years ago) was a reshaping of Earth's surface as extreme as any in the last 5 million years. Before it, the Eemian stage was actually warmer than today with sea levels 20 feet higher. Meltwater pulse 1B at 11,500 years ago coincides precisely with major changes in the geological record. The Holocene has been more climatically stable than what came before.

Key Facts

  • The Younger Dryas (12,000-11,600 years ago) was a reshaping of Earth's surface as extreme as any in the last 5 million years
  • The Eemian stage (116,000-130,000 years ago) was warmer than current Holocene with sea levels 20 feet higher
  • Meltwater pulse 1B occurred at 11,600 years ago
  • The Younger Dryas erased evidence of whatever preceded it
  • At least two to three major spikes beyond the Younger Dryas include events at 146,000 and 11,600 years ago
  • The Holocene has been more climatically stable than the Eemian
