Urban hot spots of Global Temperature of Emergence of several CIDs for the biggest cities in the CORDEX domains

One important type of information for stakeholders is the time of emergence (TOE) of a particular climatic impact-driver (CID) in a specific region as reported also in the latest IPCC AR6. The TOE is the time when a certain signal emerges from the natural variability, thus it is an indicator of the magnitude of the climate change signal and it can be very important in a risk framework for mitigation purposes. Moreover, a focus on big cities and urbanized areas is becoming more and more crucial to plan adaptation strategies.The Euro-CORDEX regional climate projections, together with the CORDEX-CORE ones, are a good starting point to look at the impact of urbanization on climate change since most of the models in those ensembles are able to detect urban areas and use an urban model parametrization. In this study, we use the available CORDEX ensembles to compute tailored CIDs for some big urban areas all over the world, in order to understand which is the role of the urban effect in enhancing or dumping the specific signal compared to the more rural regions.The analysis will be done at several resolutions according to the data availability to assess the need for higher-resolution information. As expected urban areas show an exacerbation of the extreme climate signal for several CIDs highlighting the importance of the development of tailored local adaptation strategies.
