The Impact of Different Atmospheric CO2 Concentrations on Large Scale Miocene Temperature Signatures
Based on inferences from proxy records the Miocene (23.03–5.33 Ma) was a time of amplified polar warmth compared to today. However, it remains a challenge to simulate a warm Mioce…
Direct observation of microcrack development in marble caused by thermal weathering
