High-latitude volcanic eruptions can significantly impact the climate system. Simulations were conducted with the Goddard Institute for Space Studies (GISS) modelE general circulation model of the Katmai (58°N) as well as one with 3x the optical depth of Katmai (3x Katmai), and …

I examine links between catastrophic events, climate variability, and biotic modulation on evolution at the ecosystem-level of orbitally-paced Early Mesozoic Pangean great lakes. One of the largest controls on the diversity of taxa within ecosystems is mass extinction. High-reso…
