Regional and global sea-surface temperatures during the last interglaciation

Jeremy S. Hoffman, Peter U. Clark, Andrew C. Parnell, Feng He
  • States that understanding how warm intervals affected sea level in the past is vital for projecting how human activities will affect it in the future
  • Compiles estimates of sea surface temperatures during the last interglacial period, which lasted from about 129,000 to 116,000 years ago
  • Finds that the global mean annual values were ∼0.5°C warmer than they were 150 years ago and indistinguishable from the 1995–2014 mean
  • Conclude that this is a sobering point, because sea levels during the last interglacial period were 6 to 9 m higher than they are now
