The world’s holiday destinations are changing in any case, regardless of the immediate effects of tourism – beaches are washing away as sea levels rise, and there will be more algal blooms and jellyfish in tourist areas, and coral is dying due to higher sea temperatures. Many areas are subject to worsening water shortages and wild fires. Storms will increasingly be stronger and more frequent, and rainfall will be more intense. Summers will be longer, but ski seasons will be shorter, and lower-altitude resorts will find themselves without natural snow. If they resort to making artificial snow, this is also very damaging due to the amount of water taken from streams and the additives used.
Glaciers are melting (it’s estimated that Kilimanjaro will be ice-free by 2020, and the US’s iconic Glacier International Peace Park by 2030), and the Arctic Ocean may be ice-free in summer as soon as 2030 (opening up the possibility of cruises through the North West Passage, which was ice-free for the first time in 2007). The polar regions are seeing the fastest temperature increases, with the Antarctic Peninsula warming by 5°C over the last fifty years, and a 40% decline in sea ice cover over the last 25 years.
