https://en.wikipedia.org/wiki/Eocene#Equable_climate_problem https://en.wikipedia.org/wiki/Eocene#Equable_climate_problem > BAYSPAR measurements indicate extremely high sea surface temperatures of 40 °C (104 °F) to 45 °C (113 °F) at low latitudes, I'm going to take a wild guess that humans aren't doing so good near the equator with 45°C oceans. Though it's definitely interesting that the temperature gradient flattened out so much.
