Short summary
Climate equability is a paradox in paleoclimate research, but modeling suggests that strong seasonality should be a feature of greenhouse Earth periods too. Records of temperature from floral assemblages, paleosol geochemistry, clumped isotope thermometry, and downscaled models during the early Eocene show that the mean annual range of temperature was high, and may have increased during warming events. This has implications for predicting future seasonal climate impacts in continental regions.
