I am a palaeoclimatologist and palaeoecologist with a focus on Arctic amplification of temperature. The Arctic is warming at 4x the global average, tracking or exceeding our most extreme climate model scenarios and the source of this error is unknown. Applying these same models to warm periods of the past, and testing them against climate reconstructions, allows us to investigate why they may be insensitive to Arctic warming. This will ultimately improve climate model prediction for policy and climate impact mitigation. This question has led to me to apply a broad range of palaeoclimate and palaeoecological reconstruction methods, using the remains of organisms from the past; from fire and cloud reconstruction, to beetles, molluscs, and plants as indicators of their climate, I take a systems approach to understanding our past, to better our future. Central to this, is the interdisciplinary pursuit of data-model comparison. I am the lead of the Neoegene Terrestrial Climate group in the PAGES working group PlioMioVAR working toward a synthesis of Neogene terrestrial climate records; the terrestrial data representative on the PlioMIP3 steering committee; on the experimental design team for MioMIP2; and a founding member of the PoLAR-FIT working group.
I am currently working on several projects related to high latitude climate processes.
I am working at multiple Pliocene (5.3–2.6 million years ago) sites across the North American Arctic, including on Ellesmere Island and in Alaska, to recostruct the climate and vegetation during the period most analogous to our near future climate state. I am using pollen, bacterial lipids, microscopic features of leaves, charcoal and more to recosntruct these past environments and learn more about the feedbacks that shape our most warming-sensitive regions under sustained high CO2.
I am working on the development of new palaeoclimate proxies for deep time, that investigate some of our most persistent sources of uncertainty in climate modelling: Clouds. This ambitious project is in collaboration with palaeoclimate modellers and statisticians at the University of Leeds, following my Marie Sklodowska-Curie Fellowship.
On the broader scale of palaeoclimate data-model mismatch, I am leading the synthesis of Neogene Terrestrial Climate for comparison with model outputs from the Miocene Model Intercomparison Project Phase 2 and Pliocene Model Intercomparison Project phase 3.
I am also developing new research directions in the refinement and development of proxies for winter temperature at the extremes; charcoal-based fire intensity proxies for fire regime reconstructions; and a framework for understanding the timing of climate and vegetation change through the Cenozoic in northeastern Australia.
