New Eocene fossil data suggest climate models may underestimate future polar warming – Research News https://www.floridamuseum.ufl.edu/science/fossil-data-suggest-climate-models-may-underestimate-polar-warming/
A new international analysis of marine fossils shows that warming of the polar oceans during the Eocene, a greenhouse period that provides a glimpse of Earth’s potential future climate, was greater than previously thought. By studying the chemical composition of fossilized foraminifera, tiny sing
