Analysis by European Commission experts places parts of Spain among those regions where the number of overnight stays will fall the most with the advance of global warming. Cyprus and Greece will suffer the largest drop
Hopefully the tourists stay within reasonable distance of their home and avoid planes, flying/international travel is way too destructive to be so normalized.
Like taking a round trip from Copenhagen to Tokyo and back emits something like 7x the amount of CO2 a typical danish person emits in a whole year.
I totally agree with your statement, however, the data seems wrong. A Copenhagen-Tokyo roundtrip emits 2.7t of CO2 (myclimate.org) and the per capita emissions of Denmark are 5t of CO2 per year. So the trip amounts to half the yearly emissions, which is still significant though.
Especially in the context of the article and Europe, flying is of course even worse, since many alternatives exist.
Generally the per capita emissions should be around 0.6t to stay within the planetary limits. So yeah, flying really isn't great in any way.
