talks
Modeled Cross-Tropopause Mass Exchange Comparable in Modern and Snowball Earth
Published:
A talk at the “Ice, oceans, and atmospheres on Earth and elsewhere” workshop. Described GCM model results comparing mass exchange between the stratosphere and troposphere of the modern and snowball Earth. This work was eventually incorporated into a paper published as The Snowball Stratosphere.
Pressure-dependence of silicate weathering feedback may be weaker than usually assumed in studies of rocky planet climate
Published:
A talk presented at AGU Fall Meeting in San Francisco in 2019. The title is actually incorrect – I presented a talk about the hydrologic regulation of silicate weathering.
Hydrologic Control of Silicate Weathering and Rocky Planet Climate Stability
Published:
A talk about my research on silicate weathering, given at the conference “Rocky Worlds: from the Solar System to Exoplanets” at Cambridge.
Energetic and Thermodynamic Limits on Continental Silicate Weathering Strongly Impact the Habitability of Wet, Rocky Worlds
Published:
I gave a talk at BPSC 2020 on my research into limits to the silicate weathering feedback.
