Climate change is increasingly apparent. They manifest in all spheres of life, including tourism, a leisure activity sensitive to climate. Our research underscores the fact that when seen through the lens of tourism geography, climate, one of the components of tourism destinations, is a decisive factor. Having become a mass phenomenon, sensitive to the altering of optimal climatic parameters for tourism due to the global warming process, tourism clearly stands under the influence of climate change. The study also explores the possible measures of accommodation to such phenomena that human society can resort to, obviously at rather high costs: coastal improvements and the restructuring of hydrographic basins, the “elevation” of mountain resorts to higher altitudes, the integrated planning of activity in the tourism sector with activity in other fields, and so on.
