Multi-sectoral hotspots of climate <strong>change</strong> under a global warm<strong>in</strong>g of 2 °C<br />

Note: The <strong>impacts</strong> as shown <strong>in</strong> the maps refer to a warm<strong>in</strong>g of 2 °C above the pre-<strong>in</strong>dustrial level. The time period when warm<strong>in</strong>g of 2 °C<br />
above the pre-<strong>in</strong>dustrial level is reached varies depend<strong>in</strong>g on the RCP scenario <strong>and</strong> climate model. For RCP8.5, most climate models<br />
project that the 2 °C threshold will be reached <strong>in</strong> the 2030s, while for RCP4.5 most climate models project the 2 °C threshold to be<br />
reached around the middle of the century.<br />

southern <strong>Europe</strong> have been identified as multi-sectoral<br />
hotspot 'losers', <strong>in</strong>dicat<strong>in</strong>g that the <strong>impacts</strong> from a<br />
chang<strong>in</strong>g climate on the sectors <strong>in</strong> these regions are<br />
projected to be predom<strong>in</strong>antly negative. Regions with<br />
a particularly high number of sectors projected to be<br />
negatively affected are found on the Iberian Pen<strong>in</strong>sula,<br />
<strong>in</strong> southern <strong>and</strong> central France, <strong>and</strong> <strong>in</strong> Italy (see right<br />
panel of Map 6.2) (IMPACT2C project, 2015). Likewise,<br />
a study by the ISI-MIP project has identified southern<br />
(<strong>and</strong> also south-eastern) <strong>Europe</strong> as the region with<br />
potentially the most severe <strong>impacts</strong> across multiple<br />
sectors <strong>in</strong> <strong>Europe</strong> (<strong>and</strong> actually the second largest<br />
hotspot region globally) (Piontek et al., 2014).<br />
The IMPACT2C results emerge from an assessment of<br />
eight impact criteria <strong>in</strong> relation to the sectors 'water',<br />
'agriculture', 'tourism' <strong>and</strong> 'ecosystems', <strong>and</strong> based<br />
on up to 10 regional climate models simulat<strong>in</strong>g the<br />
RCP4.5 <strong>and</strong> RCP8.5 scenarios. The impact criteria used<br />
are cool<strong>in</strong>g water level, hydrological droughts (river<br />
low flow level, 10-year return period), floods (10-year<br />
return period), crop yield (w<strong>in</strong>ter wheat), value at risk<br />
for summer <strong>and</strong> w<strong>in</strong>ter tourism (measured as <strong>change</strong>s<br />
<strong>in</strong> overnight stays), <strong>and</strong> terrestrial ecosystem function<br />
(net primary productivity <strong>and</strong> soil organic carbon). For<br />
each criterion, w<strong>in</strong>ner hotspots <strong>and</strong> loser hotspots<br />
were def<strong>in</strong>ed based on EU policy thresholds <strong>and</strong><br />
scientific literature (depend<strong>in</strong>g on availability). Robust<br />
hotspots were def<strong>in</strong>ed either based on a majority rule,<br />
such that the majority of models (e.g. 6 out of 10) had<br />
to agree that a given grid cell was <strong>in</strong>deed a hotspot,<br />
or, for some criteria, based on the median response<br />
over all simulations. In the assessment, however,<br />
SSP <strong>in</strong>formation (i.e. potential future socio-economic<br />
<strong>change</strong>s, such as demography <strong>and</strong> economy) was taken<br />
<strong>in</strong>to account only for tourism (SSP1, 2 <strong>and</strong> 3).<br />
6.2.3 Multi-hazard exposure<br />
Multi-sectoral <strong>impacts</strong> <strong>and</strong> vulnerabilities can also be<br />
studied by explicitly dist<strong>in</strong>guish<strong>in</strong>g between multiple<br />
climate-related hazards. Such an approach shows that<br />
<strong>Europe</strong> could face a progressive <strong>in</strong>crease <strong>in</strong> overall<br />
climate-related hazards from the 2020s to the 2050s<br />
<strong>and</strong> further to the 2080s, with a prom<strong>in</strong>ent spatial<br />
gradient from north-eastern towards south-western<br />
<strong>Europe</strong> (see Map 6.3). This gradient is ma<strong>in</strong>ly driven<br />
by projected <strong>in</strong>creases <strong>in</strong> heat waves, droughts <strong>and</strong><br />
