The period leading to and immediately after the release of the IPCC’s fifth series of climate change assessments saw substantial efforts by climate change denial interests to portray anthropogenic climate change (ACC) as either unproven theory or a negligible contribution to natural climate variability, including the relationship between tourism and climate change. This paper responds to those claims by stressing that the extent of scientific consensus suggests that human-induced warming of the climate system is unequivocal. Secondly, it responds in the context of tourism research and ACC, highlighting tourism’s significant contribution to greenhouse gas emissions, as well as climate change’s potential impacts on tourism at different scales. The paper exposes the tactics used in ACC denial papers to question climate change science by referring to non-peer reviewed literature, outlier studies and misinterpretation of research, as well as potential links to think-tanks and interest groups. The paper concludes that climate change science does need to improve its communication strategies but that the world-view of some individuals and interests likely precludes acceptance. The connection between ACC and sustainability illustrates the need for debate on adaptation and mitigation strategies, but that debate needs to be grounded in scientific principles not unsupported skepticism

This editorial for the special issue on 'Desirable Tourism Transport Futures' explores approaches to transitioning the tourism sector to a sustainable emissions path. It starts by describing an undesirable tourism transport future associated with a business-as-usual scenario, which will inevitably cause the climate mitigation goals outlined in the Paris Climate Accord (2015) to soon become unattainable. We then outline a scenario for a climatically desirable future, the social and economic implications of which are explored. The challenge of mitigating climate change is critical to desirable tourism transportation futures, although to date relatively little attention has been paid to this aspect of sustainable tourism. This is an omission that must be urgently addressed. This special issue addresses desirable tourist transportation futures in relation to deep cut emissions reductions and, therefore, mitigation of climate change-induced environmental impacts. It is important that desirable tourism transport futures are critically considered in terms of both spatial and temporal scale. The scenarios that inform this introductory article provide some insights at the long-term macro-scale. These scenarios are associated with desirable and undesirable elements that will no doubt continue to be the subject of much debate and contestation. While these scenarios will represent both opportunities and threats to the full spectrum of tourism industry stakeholders, they should also inform manifold avenues of future research at a critical moment in the evolution of tourism transportation and the pursuit of the UN Sustainable Development Goals (2015-2030).
