I started at Oxford in 2014, where I studied for a Masters in Physics. During the summer in 2017 I worked with Prof. Myles Allen and others on greenhouse gas metrics which and carbon budget estimation. In the final year I specialised in climate science, including taking the Atmospheric, Oceanic and Planetary Physics course. Having finished my Masters in 2018 I began a DPhil. The PhD is funded by NERC and sits under the Environmental Research DTP here at Oxford.
In my PhD I am researching the trends in non-CO2 contributions to contemporary global warming. Over the last two decades many datasets which reflect the energy balance of the climate system suggest that the anthropogenic contribution to global warming has accelerated. Determining whether this is the case is extremely important, as present day trends in anthropogenic global warming are the single most important variable for policymakers determining the scale and timing of climate policy in the coming decades.
In order to assess the contributions to global warming, I analyse satellite observations of the climate system over the last 20 years, and use the information gained alongside global climate models to fingerprint the individual contributions from a range of pollutants to recent trends. The focus is on aerosols, as these are assumed to have contributed the most to recent trends.
Output from this work has a fairly large policy significance at present, and I am also interested in applications of physical climate research in the business and policy arenas.
