RSNSW 1318 OGM: November 2023

The Society's 1318th Ordinary General Meeting, held in the Gallery Room of the State Library of NSW on 29 November 2023, was treated to a most thought-provoking lecture on sea-level rise by the winner of the 2022 RSNSW James Cook Medal, Emeritus Professor John Church AO FAA FTSE of the UNSW Sydney Climate Change Research Centre. 

His talk, titled “What do we really know about 20th- and 21st-century sea-level change?”, explored the cause of sea-level rise and provided persuasive evidence that it is due to two main factors: the expansion of the ocean due to heating and the addition of water from the increased melting of glaciers. 

The presentation is now available on the Society's YouTube channel. Some images from the occasion are available at this link for viewing and downloading.
