To address societal concerns over rising sea levels and associated extreme events and to quantify the impacts of sea-level changes on coastal communities, ecosystems and the global economy it is key to understand the contributions to these changes. In this session, we respond to this need and invite contributions from the international sea level community that improve our knowledge of the past, present and future changes in global and regional sea levels, extreme events and coastal impacts.
The session focuses on studies exploring the physical mechanisms for sea level rise and variability as well as the drivers of these changes, at any time scale (from paleo sea level to high-frequency phenomena to long-term projections), using observations and/or model simulations. Investigations on linkages between variability in sea level, heat and freshwater content, ocean dynamics, land subsidence and mass exchanges between the land and the ocean associated with ice sheet and glacier mass loss and changes in the terrestrial water storage are welcome. Studies focusing on future sea level changes are encouraged, as well as those assessing short-, medium-, and long-term impacts on coastal environments and their implications.
