This talk will first present a new reconstruction of global sea-level change over the last 4.5 Myr which encompasses the initiation and intensification of Northern Hemisphere glaciation and sea-level variability over the last 2.5 Myr associated with the Pleistocene Ice Ages. Several results from this reconstruction pose new challenges to our understanding of ice-sheet-climate interactions, including ice-sheet response to orbital forcing, ice-sheet inception and growth under a range of global temperature, and the middle Pleistocene transition. The second part of the talk will examine future long-term (10-kyr) sea-level commitment to a range of emission scenarios and the development of a carbon budget to limit sea-level rise below a given target.
