I am a palaeoclimatologist and palaeoecologist foccused on resolving climate data-model mismatch. 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.
