In a study, entitled 'Time is of the essence: adaptation of tourism demand to climate change in Europe', it has been found that changing climate conditions could make sunny southern tourist destinations less attractive.

This temperature rise could also make it simply too hot to comfortably visit Mediterranean countries in the height of summer.

While the paper says that Spain and Bulgaria would be the biggest losers, northern Baltic states like Latvia, Estonia, Slovenia and Slovakia could see their tourism industries boom.
