I am interested in how the climate evolved in the past and will do so going into the future. Like the climate, my career path has steadily evolved since its start in physics (BSc, Durham, 2002). I then studied coupled climate modelling (PhD in Meteorology, University of Reading, 2007), which combines physical oceanography with atmospheric physics. A post-doc in the Geology & Geophysics department at Yale exposed me to the true scale of Earth history.

I have been at UCL Geography since 2011, when I was brought in to launch two MSc programmes: in Climate Change and Environmental Modelling. I still convene both programmes, so contact me about admissions.

The Earth is heading to a climate state not seen in the history of our species. The climate models we use to make projections of that state contain considerable uncertainty. I try to understand, reduce and quantify this uncertainty. Identifying why climate has changed in the past can help us understand the range of its future changes. This is especially true of past warm periods and my particular choice is the Pliocene (around 5-3 million years ago when CO2 levels were last at their present, elevated ones).

  • Uncertainty in Future Climate Projections
    • Characterising the uncertainty in ocean models from physical parameters (Collins et al., 2007; Brierley et al., 2010)
    • I am working with colleagues in UCL Statistical Sciences to develop improved techniques for uncertainty quantification of climate models (the ReCoVER project)
    • Using emergent, observational constraints on future projections (Ho et al., 2015, is the first attempt to apply this approach with hydrological models)

Climate change is a global problem that needs to urgent action to safeguard our future. My research just really diagnoses the problem we face, rather than providing a part of the solution. I see that the biggest contribution I can make is through using my expertise to educate others and raise awareness of the issue. This has led me engage with the public through a series of conventional science education activities. The most substantial of these have been teaching at geography 'A' level revision courses and a short course at the Royal Institution that ran in both 2013 and 2014. I have also helped the Royal Meteorological Society produce school resources about past climates.

I aim to be generous with my time to field scientific questions be they from large institutions (such as the BBC or the UK Government) or individuals. This has led me to fielding media enquiries (mainly to print journalists, but I have appeared on the national news).

As well as personally talking about climate science, I've been thinking about the best way that dialogue should take place. Firstly, where possible it should actually be a bespoke dialogue rather than an information-deficit barrage of facts. This has lead me to be involved with a policy commission based at UCL. We have given evidence to Parliament and authored a cross-disciplinary report on the topic. This work has been folded into a training workshop for PhD students at the London NERC DTP.

I am responsible for the MSc in both Climate Change and Environmental Modelling that are run by UCL Geography.
