For all cities, the range in impacts from using an absolute threshold shift was smaller than the range from using multiple GCMs and/or RCPs (Figure 2).
Electing to model adaptation with a 4[degrees]C absolute threshold shift for Milan would suggest that the least effect climate change will have on heat-related mortality is an additional 44 heat-related deaths (per 100,000) each year compared with the present day (Figure 2).
Absolute threshold shifts are a popular method for modeling adaptation in impact studies, but they have always been shifted by between 1[degrees]C and 4[degrees]C without being informed by epidemiological evidence of observed threshold shifts (Dessai 2003; Gosling et al.
Overall, we recommend that future impact studies model adaptation by absolute threshold shifts and reductions in ERF slope.
Cluster 1 was the first cluster delineated and it contains only definitions/variants that are based on absolute thresholds for several of the daily heat metrics.
