Seminar | July 8, 2019 – h. 12:30 pm CEST
Ca’ Foscari Challenge School, VEGA (Aula Cancelletto, 1st floor), Venice-Mestre


Speaker: Ilan Noy, Victoria University of Wellington, New Zealand
Introduced by Jaroslav Mysiak (Euro-Mediterranean Center on Climate Change – CMCC, RAAS Division Director)


We use a probabilistic event attribution framework to estimate the costs associated with extreme weather events that are attributable to anthropogenic influence on the climate system.
Using examples from the US (Hurricane Harvey) and New Zealand (flood events), our results indicate that the climate-change ‘footprint’ of Harvey was almost US$70Bn, and that the climate-change
footprint of NZ floods is economically very significant as well. We extrapolate these results more broadly, and show that these ‘bottom-up’ estimates of losses and damages associated with climate
change are significantly larger than those obtained with ‘top-down’ estimates, such as those implied by Integrated Assessment Models.

After the presentation by Ilan Noy there will be a discussion with all the participants.
Contributions from all the participants are well encouraged.

Working language: English
