Sea-level change and superstorms; geologic evidence from the last interglacial (MIS 5e) in the Bahamas and Bermuda offers ominous prospects for a warming Earth

In terms of Lyellian uniformitarian principles, the trilogy of coeval deposits of MIS 5e described herein do not translate to our modern climate parameters, and further cannot be explained by coincidental megatsunami. In our industrial world, rapidly increasing atmospheric CO2 rates (> 2 ppm/yr) have surpassed 408 ppm, levels not achieved since the Pliocene 3 Ma ago, while global temperature increased ~ 1 °C since the 1870s. With greatly increased CO2 forcing at unmatched rates, except perhaps during global extinction events, dramatic change is certain. In the interest of our future world, we must seek to understand the complex set of linked natural events and field observations that are revealed in the geology of past warmer climates.
