Using interviews and surveys of 212 households in villages situated at different elevations in the Everest National Nature Preserve (ENNP), correlations and comparative analyses were employed to reveal the residents' perceptions and understanding of climate change and its effects on the ENNP. Results showed that: (1) nearly all residents thought that climate warming and ice-snow landscape decrease were very significant, but there was an obvious difference between the residents' cognition and observations to the change of runoff; (2) higher altitude is, more obvious warming is, and stronger residents' perception of climate change and its impacts is in the ENNP, for which educational level and age were the main factors affecting their degree of perception; (3) especially, higher altitude is, more frequent the tourism participation of residents is and higher their income is; and (4) because the centralized pollutant treatment facilities have a low efficiency, and because the area receives a large number of tourists whose activities are spatially scattered, the potential risk of environmental pollution has been increasing in recent years. At present there is an urgent need for policy suggestions at the strategic level of national ecological security and interregional equity principles concerning the adaptation to climate and environmental changes in the ENNP.

Using the coupled coordination degree model, DEA coupled coordination efficiency model, and spatial autocorrelation model, this study explored the dynamic coupled coordination relationship and spatial correlation between the ice-snow tourism network attention and tourism industry development in 31 Chinese provinces and proposed suggestions pertaining to development. Our findings showed that (1) most provinces have not yet achieved excellent coordinated development between the two systems, and the coupled coordination efficiency is low. Each province's coupled coordination degree and coordination efficiency exhibited a small increase. (2) Spatial differences in the coupled coordination level and coordination efficiency of the two systems in each province were more evident. In seven provinces, including Heilongjiang, tourism industry development demonstrated a relatively high utilization rate and enhanced ice-snow tourism network attention. (3) The rankings of the coupled coordination degree and coordination efficiency of the two systems in each province remained relatively stable at the upper and lower ends, with large changes in the central provinces. The coupled coordination efficiency of Heilongjiang, Beijing, Jilin, and Shanghai remained at the top of the list steadily, whereas Tibet, Anhui, and Qinghai stayed at the bottom. In contrast, the ranking of the coupled coordination efficiency of Inner Mongolia, Henan, and Jiangsu displayed a great change. (4) The spatial correlation analysis revealed a positive correlation that decreased annually. Some provinces exhibited characteristics of spatial aggregation, with a high-high aggregation effect in Liaoning and Jilin, a low-low aggregation effect in Gansu and Qinghai, and no spatial aggregation effect in most other provinces.

The perceptions and attitudes of community residents are a mirror of tourism development. Little research has been conducted on the effects of place attachment and emotional solidarity on community residents' attitudes toward tourism in China's glacier tourism-related areas. In this paper, we selected the southernmost marine glacier in China, Hailuogou Glacier Forest Park, as a case study, and constructed a structural equation model of residents' tourism perceptions and attitudes based on 358 valid questionnaires obtained from fieldwork. We analyzed the logical connection and influencing relationship between place attachment, residents' perceptions (residents' benefits and environmental perceptions), and community residents' attitudes (security, support, satisfaction), and explored countermeasures and suggestions for building a harmonious host-customer relationship in the Hailuogou area to improve glacier tourism. The results of the study show that the influence of place attachment and residents' perceptions on emotional solidarity is different from the degree of influence of emotional solidarity on residents' tourism attitudes, with the most significant positive influence of place attachment on emotional solidarity and the greatest influence of emotional solidarity on sense of security. Emotional solidarity had a certain mediating effect between place attachment, residents' perceptions, and residents' tourism attitudes. Significantly, emotional solidarity had the most fully mediated effect between place attachment and support, reaching 73.61%. The moderating effect of place attachment reflects that the higher the place attachment, the weaker the correlation between residents' perceptions and residents' tourism attitudes. Meanwhile, residents' tourism attitudes will weaken their influence with the increase in emotional solidarity. Based on the above results, relevant suggestions are made to provide a theoretical basis and decision-making reference for the development and management of glacier tourism destinations.

Glaciers are attracting increasing attention in the context of climate change, and glacier tourism has also become a popular tourist product. However, few studies have been conducted concerning the image of glacier tourism destinations. To address this gap in the literature, in this study, we extracted destination images from 138,709 visitor reviews of 107 glacier tourism destinations on TripAdvisor using latent Dirichlet allocation (LDA) topic modeling, identified destination image characteristics using salience-valence analysis (SVA), and analyzed the differences in glacier tourism destination image characteristics across seasons and regions. According to the findings, the image of a glacier tourism destination consists of 14 dimensions and 53 attributes, with landscapes and specific activities representing the core image and viewing location and necessity representing the unique image. We identified significant seasonal and regional differences in the image of glacier tourism destinations. Finally, we discussed the unique image of glacier tourism destinations, the reasons for differences in the images, and the characteristics of different glacier tourism regions. This research could assist in the scientific management of their core images by glacier tourism destinations, as well as in the rational selection of destinations and travel timing by glacier tourists.

Ice and snow tourism has yielded considerable socioeconomic benefits, especially for the countries and regions that are rich in ice and snow resources. Boosted by the Beijing Winter Olympics, China's ice and snow tourism economy is likely to usher in a period of high-quality development. This study utilized Hailuogou Glacier Forest Park, a relatively well-developed glacier tourism area in China, as the study area. We used data on the regional GDP of Ganzi Prefecture and the comprehensive tourism revenue of Hailuogou scenic area from the period of 1990-2021 to quantitatively analyze the reciprocal feedback relationships between the regional economic growth of Ganzi Prefecture and the development of Hailuogou glacier tourism. The analyses were performed through the construction of a VAR model and through conducting robustness tests using the instrumental variable method. The results show that there is a long-term equilibrium cointegration relationship between regional economic growth in Ganzi Prefecture and tourism development in the Hailuogou scenic area, with each 1% increase in the former driving a corresponding growth of 2.01% in the latter. There is an asymmetric reciprocal feedback relationship between the economic growth of Ganzi Prefecture and the development of tourism in the Hailuogou scenic area. Economic growth in Ganzi Prefecture significantly contributes to the development of glacier tourism in Hailuogou over a longer period of time, with a contribution rate of 49%; meanwhile, the development of tourism in the Hailuogou scenic area has a limited effect on the quality and acceleration of economic development in Ganzi Prefecture, with a contribution rate of 16%. Based on the above results, relevant policy recommendations are proposed to provide a theoretical basis and decision-making reference for the high-quality development of the Hailuogou scenic area in the post-COVID-19 and post-Winter Olympics era.

Tourism plays an important role in Kashgar's socio-economic development. Climate change has a profound impact on the development of tourism. However, basic research on climate change and its impact on tourism remains insufficient in Kashgar. Using the atmospheric reanalysis data ERA5 and the universal thermal climate index (UTCI) model, climate change and climate comfort were evaluated from 1979 to 2018. The annual mean UTCI was -2.3 degrees C, i.e., at the coolish level, with moderate cold stress, illustrating that Kashgar's tourism climate was weak. The obvious increase in the annual mean air temperature led to an obviously increased UTCI and a lengthened comfortable period, which provides possibilities to exploit an attractive climate and the potential for tourism. The poor climate conditions imply that the development of Kashgar's tourism should depend more on the diversification and uniqueness of tourism products and the quality of tourism services. Therefore, the development of increased tourism products and the expansion of tourism regions, in the context of improving climate conditions, were focused on. We expect this case study to provide a reference for consumer travel decision-making and a necessary scientific basis for the planning and implementation of a tourism-based national promotional strategy in western China.

Detailed examination of the impact of modern space launches on the Earth's atmosphere is crucial, given booming investment in the space industry and an anticipated space tourism era. We develop air pollutant emissions inventories for rocket launches and re-entry of reusable components and debris in 2019 and for a speculative space tourism scenario based on the recent billionaire space race. This we include in the global GEOS-Chem model coupled to a radiative transfer model to determine the influence on stratospheric ozone (O-3) and climate. Due to recent surge in re-entering debris and reusable components, nitrogen oxides from re-entry heating and chlorine from solid fuels contribute equally to all stratospheric O-3 depletion by contemporary rockets. Decline in global stratospheric O-3 is small (0.01%), but reaches 0.15% in the upper stratosphere (similar to 5 hPa, 40 km) in spring at 60-90 degrees N after a decade of sustained 5.6% a(-1) growth in 2019 launches and re-entries. This increases to 0.24% with a decade of emissions from space tourism rockets, undermining O-3 recovery achieved with the Montreal Protocol. Rocket emissions of black carbon (BC) produce substantial global mean radiative forcing of 8 mW m(-2) after just 3 years of routine space tourism launches. This is a much greater contribution to global radiative forcing (6%) than emissions (0.02%) of all other BC sources, as radiative forcing per unit mass emitted is similar to 500 times more than surface and aviation sources. The O-3 damage and climate effect we estimate should motivate regulation of an industry poised for rapid growth.

Due to the impact of COVID-19, people's demand for non-contact tourism is increasing. The development of Internet technologies such as the Internet of Things, virtual reality (VR), and augmented reality (AR) can meet this demand. Internet technology makes non-contact tourism grow. However, these new technologies are emerging only within application cases, which cannot provide comprehensive methodological guidance for tourism suppliers. Despite the booming development of winter tourism in China, there are still many problems, especially affecting the tourist experience.rarchy process (AHP) and activity, setting, experience and benefit (ASEB) grid analysis were used to analyze the activities, settings, experiences and benefits of the scenic spot from the tourist perspective taking the Dagu Glacier Scenic Spot (DGSS) as an example. The research aims to increase the attraction of the scenic zone, and promote the coordinated and sustainable development of business in West China under the goal of improving tourists' experiences. The results show that: subgoals of experience (E) and benefit (B) are the main directions of the development of ice and snow tourism in the DGSS. Furthermore, the threat of benefits (TB), the threat of setting (TS), the threat of experience (TE), the opportunities of benefits (OB), the opportunities of setting (OS), and the opportunities of experience (OE) are the main concerns.

The Polar Regions (PRs) are characterized by ice sheets, sea ice, glaciers, tundra, and other cryospheric landscapes and associated aboriginal cultural features. This primitive polar landscape is a huge contrast to the current human living environment and is a strong tourist attraction. Rapid environmental changes and the emergence of conflicts between tourism development and ecological protection, have affected sustainable development of polar tourism (PT). Polar high-latitude characteristics determine the vulnerability of their environment and the higher sensitivity of PT to climate change. This study comprehensively analyzed the status quo of PT development, systematically revealed mutual influence between environmental changes and tourism development, and proposed some adaptive measures to coordinate environment protection and tourism development.

Snow cover plays a major role in the climate, hydrological and ecological systems of the Arctic and other regions through its influence on the surface energy balance (e.g. reflectivity), water balance (e.g. water storage and release), thermal regimes (e.g. insulation), vegetation and trace gas fluxes. Feedbacks to the climate system have global consequences. The livelihoods and well-being of Arctic residents and many services for the wider population depend on snow conditions so changes have important consequences. Already, changing snow conditions, particularly reduced summer soil moisture, winter thaw events and rain-on-snow conditions have negatively affected commercial forestry, reindeer herding, some wild animal populations and vegetation. Reductions in snow cover are also adversely impacting indigenous peoples' access to traditional foods with negative impacts on human health and well-being. However, there are likely to be some benefits from a changing Arctic snow regime such as more even run-off from melting snow that favours hydropower operations.
