Scientific questions

What roles have paleogeographic changes played in climate evolution over the last 100 million years?
How has vegetation evolution (diversity, physiological traits) responded to and influenced climate since the Cretaceous period?
How can paleoclimate information be integrated into models of biological diversification?
How can we build and adjust Earth System Models (ESMs) adapted to long time scales?
How can we understand climate variability (< 1 million years) in modeling ancient climates?
How can tracer simulation provide constraints on our understanding of past climates?
