Title: The role of rivers in regulating the carbon capture potential of enhanced rock weathering https://tamu.zoom.us/j/99895946887?pwd=bWdLays0TmY1d0E5UnFVOFhocFJQZz09
Abstract: Technologies and approaches that remove and sequester carbon dioxide (CO2) from Earth’s atmosphere are likely to play a significant role in mitigating anthropogenic climate disruption in the coming century. Enhanced rock weathering (ERW) on the land surface is one extensively discussed approach toward carbon dioxide removal (CDR), but the capacity of rivers to carry dissolved products derived from ERW without CO2 re-release in the river is largely unexplored, hindering a full understanding of the life cycle of ERW and its associated maximum CDR potential. This talk will present some modeling works built upon river/stream carbonate chemistry to estimate the upper limits on the carbon transport potential of rivers. Modeling challenges will be highlighted and the carbon capture potential of enhanced rock weathering will be discussed.
Noncommutative Geometry Seminar
Time: 2:00PM - 3:00PM
Location: BLOC 302
Speaker: Jiayin Pan, University of California, Santa Cruz
Title: Nonnegative Ricci curvature, fundamental groups, and asymptotic geometry
Abstract: We survey the recent developments on fundamental groups of open manifolds with nonnegative Ricci curvature. By studying the equivariant asymptotic geometry, we obtain structure results of fundamental groups such as finite generation and virtual nilpotency/abelianness.
