A perspective from four decades of studying the land carbon sink. Are we entering a jungle world?

Roughly 25% of the excess CO2 from fossil-fuel burning is being absorbed by land plants, as part of a “land carbon sink”. Typically the concern is raised that this sink may eventually turn into a source driven by climate warming, releasing additional...

Haller Hall Geo Museum 102

Speaker:Asst. Professor Alexandra Konings from Stanford Wood Institute of the Environment

Title: "Remotely sensed canopy water content as a predictor for tree mortality"

Abstract: The rate of drought-induced tree mortality has increased across the world, and is expected to continue to increase dramatically as temperatures (and associated with them, evaporative demand) continue to rise.... Read more about Department Colloquium Series

Speaker: Professor Mike Kendall from University of Bristol

Title: "Rifting in Africa: Seismological views from Afar"

Abstract: The rifting of continents and eventual formation of ocean basins is a fundamental component of plate tectonics, yet the mechanism for break-up is poorly understood. Rifting of the continents leading to plate rupture occurs by a combination of mechanical deformation and magma intrusion, but the available driving forces have been estimated to be as much as an order of magnitude smaller than those required to rupture thick continental lithosphere....

Speaker: Bill Bottke from Southwest Research Institute

Title: "Exploring the Echs of Giant Planet Migration -- Lost Neptunes and Early Bombardment"

Abstract: Heavily cratered surfaces on the Moon, Mars, and Mercury show the terrestrial planets were battered by an intense bombardment during their first billion years or more, but the timing, sources, and dynamical implications of these impacts are controversial. Dynamical models that include populations residual from primary accretion and destabilized by giant planet migration can potentially account for observations....
