"excerpt": "The Miocene Climatic Optimum (MCO, ~ 15 Ma) offers insights into warm-climate dynamics and future climate change. However, its global warmth magnitude remains uncertain due to limitations in surface and benthic proxy records. Here, we develop long-run Miocene simulations featuring deep-ocean equilibration and water isotope capability, and present a probabilistic inference framework integrating them with a global compilation of benthic foraminiferal δ18O to better constrain the MCO warmth. Our approach yields a maximum likelihood estimate of MCO global mean surface temperature of 7.5 °C above preindustrial, significantly warmer than previous benthic δ18O-based reconstructions.",

"searched": "Read the counted primary passage at source location e8b2ab1e-ffb8-80d4-ab5e-3001a90199c1 and checked the Nature Communications abstract and indexed metadata for time range, population, denominator, baseline, sampling, jurisdiction, and translation. The external abstract specifies MCO is approximately 15 Ma and that 7.5 °C is a maximum-likelihood estimate from a probabilistic model-data framework; those are material qualifiers to the headline estimate."
