November 22 , 2023 240 days 349 0
  • High rainfall helped the survival of equatorial rainforests at a time when Earth was globally warm, around 50 million years ago.
  • The Earth was around 13°C warmer than present and carbon dioxide concentration was more than 1000 ppmv during this time.
  • The existing paleoclimate data of mid and high latitudes suggest the large fluctuations in rainfall at around 50 million years ago.
  • The mechanism in which biota survives adverse conditions is still poorly known.
