Fellowship Program at Harvard University

Deadline: 18. January 2019

"Harvard’s Solar Geoengineering Research Program (SGRP) invites applications for post-doctoral and pre-doctoral fellowships, under the direct supervision of Harvard faculty. The fellowship program is loosely modeled on the successful Harvard University Center for the Environment (HUCE) fellowship program. Harvard University is an equal opportunity, affirmative action employer."

Harvard University Blog: Less rain but still wetter and greener?

"Offsetting global warming with solar geoengineering would likely weaken the water cycle and reduce regional precipitation which has raised concerns that it could lead to droughts. However, changes to plants under high CO2 concentrations could mean that a geoengineered world would be on average greener and wetter."

Phys.org: Why we can't reverse climate change with 'negative emissions' technologies

"Featured prominently in the report is a discussion of a range of techniques for removing dioxide from the air, called Carbon Dioxide Removal (CDR) technologies or negative emissions technologies (NETs). The IPCC said the world would need to rely significantly on these techniques to avoid increasing Earth's temperatures above 1.5 degrees Celsius, or 2.7 degrees Fahrenheit, compared to pre-industrial levels."

Yu, Q. (2018): Direct capture of CO2 from ambient air using solid sorbents

Yu, Q. (2018): Direct capture of CO2 from ambient air using solid sorbents. Enschede: University of Twente. DOI:10.3990/1.9789036546300

"In this thesis, a novel process is developed and experimentally demonstrated, for CO2 capture from ambient air to produce CO2 enriched air to enhance microalgae cultivation. First, an amine functionalized sorbent is selected, initially based on its water and CO2 equilibrium adsorption capacity. Subsequently, the selected sorbent is characterized on its stability under different conditions for a wide range."

Stephenson, S.; et al. (2018): Climatic Responses to Future Trans-Arctic Shipping

Stephenson, S.; Wang, W.; Zender, C.; Wang, H.; Davis, S.; Rasch, P. (2018): Climatic Responses to Future Trans-Arctic Shipping. In: Geophys. Res. Lett. 75 (2), S. 300. DOI: 10.1029/2018GL078969.

"Here we investigate impacts of shipping emissions on Arctic climate using a fully coupled Earth system model (CESM 1.2.2) and a suite of newly developed projections of 21st‐century trans‐Arctic shipping emissions. We find that trans‐Arctic shipping will reduce Arctic warming by nearly 1 °C by 2099, due to sulfate‐driven liquid water cloud formation. Cloud fraction and liquid water path exhibit significant positive trends, cooling the lower atmosphere and surface."

Harvard University Blog: Reflections on the IPCC special report on pathways to and impacts of 1.5°C

"The main difference to previous reports issued by the Intergovernmental Panel on Climate Change (IPCC) is that this report focuses on the 1.5°C target, while the the Fifth Assessment Report did not pay much attention to it, largely because too few studies even addressed this ambitious scenario. The Paris Agreement and the request to the IPCC for this latest special report have changed this: more and more studies have considered how the goal could be achieved – with similar results, but greater urgency."
