Webinar: From Global to Local scale: Predicting the effects of climate change on coastal cities

This webinar is the 5th episode in the SCORE webinar series!


SCORE Webinar #5 | From Global to Local scale: Predicting the effects of climate change on coastal cities


Much of our knowledge of the effects of climate change comes from projection models whose results are provided by climate services, such as the Copernicus Climate Change Service. These projection models describe the circulation (atmospheric, marine), at a global scale, that lacks any detail on local conditions. Even regional solutions obtained from Limited Area Models have a detail (in the modelling jargon, we call it “resolution”) that is far from our needs to predict the effects of climate change on coastal cities. For doing that, we require detailed local estimates of the combined effect of sea level rise, tidal and storm surge, rainfall inundation and, in the long term, of coastal erosion.

Estimating the effects of climate change in coastal cities hence requires increasing the resolution of urban-scale models to unprecedented levels. Within SCORE, this is accomplished by building a framework of downscaling models that take into account, simultaneously, all interactions between the state of the atmosphere and sea, forcing marine and hydrological models with global and regional solutions (e.g., EUROCORDEX). Urban-scale models simulate land and coastal flooding conditions for various scenarios and with different return times, also allowing for the evaluation of financial resilience strategies or ecosystem solutions for adaptation, following a true multidisciplinary approach and fostering, through the participatory processes of Coastal City Living Labs, the public engagement of citizens, scientists and policy-makers, to identify solutions technically and socially acceptable.

During the webinar, we will present a complete exercise on how to go from the level of climate services down to the level of detail, through the description of the entire downscaling procedure, and we will show why so many different models have to be used, and how each of them is necessary to describe those processes that, especially at the local/urban scale, are required to better understand the expected impacts.
