Project title:  Sea level response to geoengineering by 2100
Full details of the project, see  https://www.liverpool.ac.uk/studentships-earth-atmosphere-ocean/studentships/ocean/sealevelresponsetogeoengineeringby2100.html

Introduction:
Sea level rise is one of the most damaging aspects of warming climate [Church et al., 2013]. Geoengineering has been proposed as a feasible way of mitigating anthropogenic climate change, especially increasing temperatures in the 21st century.  In this study the student will answer the question” What are the expected effects of geoengineering on global and regional sea levels 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.


Project Summary:
This work aims to provide knowledge on how global and regional sea levels are likely to be changed over the next 100 years as a consequence of geoengineered reduction in radiative forcing.

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].

Work description

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.

  • To estimate changes in ocean sea level component (ocean heat content) student will utilized outputs from AOGCMs participating in the IPCC Fifth Coupled Model Intercomparison Project (CMIP5) and  Geoengineering Intercomparison Project (GeoMIP).  Student will produce maps of regional sea level patterns due to changes in ocean heat content for climate (RCP) scenarios with defined radiative forcings  and two geoengineering scenarios, in which radiative forcing has been reduced by geoengineered reduction is solar insolation.
  • Student will examine the changes in melting of glaciers and ice sheets with prescribed future radiative forcings and geoengineering scenarios using outputs from Earth System Models.
  • Maps of regional sea level changes will result from regional patterns of mass changes of the ocean from glaciers and ice sheets and changes in thermal expansion of the ocean with climate scenarios and geoengineering solutions.

Training

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).

Eligibility:
This  studentship is funded by NERC and available to UK nationals and other EU nationals that have resided in the UK for three years prior to commencing the studentship. If you meet this criteria, funding will be provided for tuition fees and stipend. If you are a citizen of a EU member state you will eligible for a fees-only award.

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
