Talk Title:  The Necromass of Borneo

Abstract: Abstract: Now more than ever we need to understand how peatlands are formed, how they thrive, and how they can be maintained to control CO2 emissions. I will describe results from a unique field program in Borneo designed to study the coupled ecological and hydrological processes that operate in tropical peatlands. We show how tropical peatlands exist because of a positive feedback between peat accumulation and water table rise. Organic material from tropical rain forests accumulates over millennia in...

Graduate Student Postdoc Seminar (GSPD) - Stephen Bourguet

12:00pm to 1:00pm

Location: 

Hoffman Faculty Lounge
Talk Title:  Lagrangian trajectories are frequently used to trace air parcels from the troposphere to the stratosphere through the tropical tropopause layer (TTL), and the coldest temperatures of these trajectories have been used to reconstruct water vapor variability in the lower stratosphere. The radiative forcing of water vapor is strongest near the tropopause; as such, the ability of these trajectories to accurately capture temperatures encountered by parcels in the TTL is crucial to water vapor reconstructions and calculations of water vapor’s radiative forcing. A potential... Read more about Graduate Student Postdoc Seminar (GSPD) - Stephen Bourguet

Harvard Crimson Article Featuring Professor Peter Huybers and Postdoc Jonathan Proctor

October 12, 2022

A new research study by Harvard faculty is shedding light on the significant influence of water supply on global crop yields and its connection to climate change.

The team — led by Harvard Earth and Planetary Sciences professor Peter Huybers — included Harvard Center for the Environment postdoctoral fellow Jonathan Proctor, Woods Hole Oceanographic Institute postdoctoral fellow Duo Chan, and UC Irvine professor Angela Rigden.

Talk Title:  Reconstructions of Cenozoic atmospheric CO2 and ocean carbon cycle perturbations

Abstract:  My research interests focus on understanding the role of the ocean, and in particular the role of marine carbonate chemistry in global climate change. As I was originally trained as a (marine) biologist, my way of approaching paleoceanographic questions often...

Talk Title:  Climatic effects of local land cover and land use change

Abstract: 

Land cover on the Earth’s surface typically varies at spatial scales smaller than the grid size of a climate model. Similarly, contemporary land use activities, such as urbanization and deforestation, are occurring at local scales than cannot be resolved by climate models. Heterogeneity in land cover causes spatial variability in...

Talk Title:  Lessons Learned about the Breathing of the Biosphere, from a Californian Network of Greenhouse Gas Flux Measurement Towers

Abstract:  This talk will revolve around lessons learned by collecting quasi-continuous and long term trace gas fluxes from a network of managed and natural fields sites across California. We will investigate if and how fluxes are...

Talk Title: Staring into the Fire: Using Observations to Understand Wildfires and Smoke

Abstract:  Recent increases in western U.S. wildfire activity have made wildland fires and the associated smoke a significant challenge for society. This problem will only grow as the climate warms. I will discuss how the atmospheric science community has used both new in situ observations and...

Talk Title:  The Thermal Histories of Solar System Moons and Small Bodies

Abstract:  The heat flow of a planetary body plays a major role in defining its evolution and current composition, driving processes from internal differentiation during its formation period through geological activity at the current time. However, these same active processes erase many of the surface signatures that would allow us to reconstruct its long-term thermal history. In this talk, I will present novel observational approaches, using primarily the ALMA interferometer...

Talk Title: Quantifying causes and consequences of historical changes in extreme climate conditions

Abstract:  Although the world is making progress in ramping up ambition to reduce greenhouse gas emissions through global, national, local and non-governmental frameworks, it has now also become clear that we are already being impacted by the global warming that has already occurred...
