Expected changes in global climate pose threats to coral reefs in several ways. More frequent storms will increasingly cause physical damage to coral reefs. Increased concentrations of carbon dioxide in the atmosphere will reduce the ability of corals to build their calcium carbonate skeletons. Higher water temperatures are likely to increase the incidence of coral diseases and temperature increases of only 1 to 1.5˚C above the long-term average can cause mass coral bleaching.

Authorities of Great Barrier Reef Marine Park published their guidelines for marine tourism operators in order to improve awareness of the ecological problems related to climate change and tourism practices. By re-posting the article we hope that our readers would know what is recommended way of organizing tours around the Great Barrier Reef and then support the most responsible operators.
