What I do
Scientific research interests and projects
My interests lie in
understanding the processes responsible
for changes in climate and sea level, as observed and as
projected by atmosphere-ocean general circulation models (AOGCMs).
- Climate sensitivity and its relationship to ocean heat uptake and the Earth
energy budget: their dependence on climate and forcing, the determination and
influence of the patterns of surface temperature and other regional climate
change, the usefulness and limitations of the forcing--feedback framework. I am
the PI of the Couplet project, funded by an advanced grant from the ERC, on
transient climate change in the coupled atmosphere --ocean system. I am a
co-investigator of the SMURPHS project, funded by as a highlight topic by NERC,
on hiatus and surge events.
- Sea-level change: processes of change in AOGCMs, causes of its simulated
regional distribution, comparison of simulated change and variability with tide
gauges and altimetry. I am coordinating a subproject (FAFMIP) of the current phase (CMIP6) of the
Coupled Model Intercomparison Project, with the aim of investigating the
reasons for different AOGCM projections of sea-level change, ocean heat uptake
and circulation change.
- Ocean heat uptake: how it comes about in AOGCMs, why their results differ,
how it relates to the Atlantic meridional overturning circulation, what we can
deduce from observations of change in the ocean interior. I am the PI of a
project (UKFAFMIP) funded by a NERC standard grant concerned with the
magnitude, patterns and mechanisms of sea level change and heat uptake in
response to atmospheric forcing. Matt Couldrey is working on this project. I am
a co-investigator in a project (TICTOC) funded by a NERC large grant on the
investigation of ocean temperature and circulation change in observations and
models using passive tracers. Quran Wu is working on this project.
- Development of the FAMOUS Earth
system model. Robin Smith is the manager of FAMOUS.
- Glacial-interglacial cycles: the mechanisms for these large changes of
global land ice cover, atmospheric carbon dioxide concentration and climate.
I am the PI of a project funded by a NERC standard grant on modelling the
last glacial cycle with FAMOUS coupled to the
Glimmer and BISICLES ice-sheet models.
Steve George is working on this project, with
Tony Payne of the University of Bristol and
Robin Smith as co-investigators.
- Modelling future changes in ice sheets and their contribution to sea-level
change. I am involved in the development of the ice-sheet/shelf modelling
component of the UK Earth system model, and in the ice-sheet subproject
(ISMIP6) of the current phase of the Coupled Model Intercomparison Project. I
am the PI of the GRIST project on thresholds for the future of the Greenland
ice-sheet, funded by NERC as part of its programme on Understanding
the pathways to and impacts of a 1.5degC rise in global temperature. Steve
George is working on this project, with Tony Payne of the University of Bristol
and Robin Smith as co-investigators. I am a member of the steering committee
for the ISMIP6
subproject of CMIP6.

many climate centres and international projects.

simulation of the interaction of ice sheets and climate
following glacial inception using a coupled AOGCM-icesheet model.
- Salvatore Pascale,
who obtained his PhD in March 2011. His thesis is concerned with the
conjecture of maximum entropy production by the climate system.
