DSNE seminar with David Parkes, Lancaster University

Conventional process-based models of regional and global glacier evolution rely on one-by-one modelling of glaciers listed in remote-sensing-based glacier inventories. Comprehensive inventories are only relatively recently available and have less reliable representation of very small glaciers and glacier fragments. Both small extant glaciers today and glaciers which fully disappeared in the course of recent warming contributed to total global losses of terrestrial ice mass, and therefore global mean sea-level rise, but were not previously accounted for in GMSLR budgets. In this talk I will describe work to construct bounds on the contribution of these ‘uncharted’ glaciers using empirically-derived power laws for glacier distribution, which results in up to 48mm of additional GMSLR between 1901 and 2015. I also argue for the general inclusion of methods to address inventory issues in glacier modelling more generally.
