Project title: Sea level response to geoengineering by 2100
Previous research shows that lower global temperatures almost immediately follow significant reduction of insolation [Robock et al., 2009]. However, sea level is an integrated response of the entire climate system to the changes in radiative forcing that reflects changes in the dynamics and thermodynamics of the atmosphere, ocean and cryosphere. Even if a drop in global air temperatures could be successfully achieved by significant reduction of radiative forcing, global sea level would respond with considerable delay due to the huge inertia of the climate system resulting from the century scale response times of oceans and ice sheets [Jevrejeva et al., 2010; Moore et al., 2011; Irvine et al., 2012].
In this project student will examine the impact of artificial reduction in the amount of solar radiation reaching the surface of Earth on the changes in global and regional sea levels.
The main objective of this study is to make projections of changes in sea level components, such as ocean heat content and contribution from melting of glaciers and ice sheets, due to effect of geoengineering with offset of greenhouse gas warming. These projections will be compared to the global and regional sea level projections with climate (RCP) scenarios, as well as long term implications from simple climate balances [Williams et al., 2012; Goodwin et al., 2015].
In this study sea level rise is considered as a combination of changes in two main sea level components: changes in global ice volume (melting of glaciers and ice sheets) and changes in global ocean heat content. Student will explore how each component will respond to the future radiative forcings and geoengineering scenarios.
The student will also benefit from a comprehensive training programme provided by NOC and the Universities of Manchester and Liverpool. This training is designed to develop each student to their full potential as a researcher and equip them to compete for the very best jobs and research opportunities. There will be opportunities to present the research results at postgraduate workshops and international conferences.
In addition, the student will have an opportunity to visit Beijing Normal University and participate in GeoMIP project experiments (funds from Beijing Normal University Geoengineering Project, three-four weeks).
Applicants should have:
· Good degree (first class or upper second) in physics, mathematics, engineering, physical oceanography or meteorology
· Knowledge in data processing, data analysis and climate model output analysis
· Experience in programming
Deadline: 4 February 2016
