Global warming, climate change and tourism of deceased, have taken the middle phase of academic study. A raging discussion is on apart from the common writings and articles published on the theme. According to the International Panel on Climate Change “Warming of the climate system is unequivocal as is now clear from notes of growths in global average air and ocean temperatures, widespread melting of snow and ice since the mid-20th century". The approaches of this manuscript are conceptual and are self-oriented to carry readers an all-encompassed state of the art. The purpose of this study is to identify and recognize the extent of research carried out to assess the impact of global warming and climate change on tourism. A three pronged approach is adopted to collect data. First, a literature search is conducted on Google search engine, second, referred research journals in the areas of global warming, climate change and tourism are consulted and third, published reports of national and international scientific associations and government establishments are surveyed. The fortunes of tourism industry, given the nature of activity, obviously depend on the magnitude and impact of global warming and climate change. Countries like USA, China, Russia, India and Australia are mainly attributed for the growing pollution and the consequent changes in the worldwide climate. Sector- wise, flying accounts for 40%, vehicles 32%, accommodations 21% and others 7% are found to be the main suppliers. By the way, all these sectors are related both directly and indirectly to the tourism industry.
