“…The spatiotemporal patterns of thermal exposure in a moderate-climate urban area were per-formed for a domain in Prague. The UTCI across Poland has been analyzed (Błażejczyk & Kunert, 2011;Błażejczyk et al, 2015b;Kuchcik 2017Kuchcik , 2020Owczarek, 2019;Tomczyk & Owczarek, 2020;Krzyżewska et al, 2020;Wereski et al, 2020;Kuchcik et al, 2021). The index has been also used to assess bioclimatic conditions in different regions in Poland (e.g., Nowosad et al, 2013;Milewski, 2013;Kolendowicz et al, 2018;Błażejczyk et al 2020;Głogowski et al, 2020) and in Polish cities (e.g., Błażejczyk et al, 2016;Bryś & Ojrzyńska, 2016;Bartoszek et al, 2017;Okoniewska, 2020;Kuchcik et al, 2021).…”

The aim of this research was to illustrate the relationship between the occurrence of very strong and extreme cold stress among human beings under the Universal Thermal Climate Index (UTCI) across Poland and largescale near-surface air temperature over the central part of Europe. The statistical downscaling procedure of canonical correlation analysis (CCA) with respect to the period between 1971 and 2000 was applied to extract the main modes of large-scale factors and their local responses. The greatest frequency of occurrence of the discussed cold stress exceeded 35% in January. Most of the variance (39-44%) of the local field in each winter month is explained by the first coupled canonical maps. T he main patterns of large-scale field show negative anomalies of monthly mean air temperature in central Europe from -1°C up to -3°C. It can indicate an increase in frequency of the occurrence of analysed cold stress categories throughout the entire area of Poland, by 2% to even over 10%, depending on the region. The best quality model was obtained in eastern Poland, especially in the north-east and south-west of Poland.

“…Some scholars pointed out that southern Europe (Crete Island in Greece, Eastern Mediterranean, Athens, Madrid (Spain), Novi Sad (Vojvodina, Northern Serbia)) were under high temperature and pressure, and climate warming has led to a significant increase in the frequency and duration of high-temperature heat waves in southern Europe and a decline in climate comfort [28][29][30][31][32][33][34][35]. In central Europe, climate change has led to an increase in the number of strong and very strong heat stress days in Poland [36]. Tourists from Germany, Ireland, and the UK would spend more holidays in their home country, and the tourism of Ireland and Britain has moved north [37].…”

In the context of global warming, a key scientific question for the sustainable development of the Arctic tourism industry is whether the region’s climate is becoming more suitable for tourism. Based on the ERA5-HEAT (Human thErmAl comforT) dataset from the European Center for Medium-range Weather Forecasts (ECMWF), this study used statistical methods such as climatic tendency rate and RAPS to analyze the spatial-temporal changes in Arctic summer climate comfort zones from 1979 to 2019 and to explore the influence of changes in climate comfort on Arctic tourism. The results showed the following: (1) With the increase in the Arctic summer temperature, the universal thermal climate index (UTCI) rose significantly from 1979 to 2019 at a rate of 0.457 °C/10a. There was an abrupt change in 2001, when the climate comfort changed from “colder” to “cool”, and the climate comfort has remained cool over the past decade (2010–2019). (2) With the increase in Arctic summer temperatures, the area assessed as “comfortable” increased significantly from 1979 to 2019 at a rate of 2.114 × 105 km2/10a. Compared with the comfortable area in the 1980s, the comfortable area increased by 6.353 × 105 km2 over the past 10 years and expanded to high-latitude and high-altitude areas, mainly in Kola Peninsula, Putorana Plateau, and Verkhoyansk Mountains in Russia, as well as the Brooks Mountains in Alaska. (3) With the increase in Arctic summer temperatures, the number of days rated comfortable on 30% of the grid increased significantly from 1979 to 2019 (maximum increase: 31 days). The spatial range of the area with a low level of comfortable days narrowed and the spatial range of the area with a high level of such days expanded. The area with 60–70 comfortable days increased the most (4.57 × 105 km2). The results of this study suggest that global warming exerts a significant influence on the Arctic summer climate comfort level and provides favorable conditions for further development of regional tourism resources.

“…Based on UTCI they identified coastal and mountainous regions as the areas with the least thermal stress, and the central region as the area with the highest thermal stress.

This study investigated the variations in relative humidity (RH) and its impacts on outdoor thermal comfort in Poland. The study considered hourly RH data from 44 stations over the period 1995–2020. A countrywide declining trend in average RH was seen over the above period. This trend was more pronounced at stations in central and northwestern Poland. In the majority of the stations, in spring and summer, a statistically significant decline in the average RH was seen in the period 2008–2020 (second half of data) in comparison to that in the period 1995–2007 (first half of data). In all seasons, during the period 1995–2020, frequency distributions of RH corresponding to all stations were heavily left‐skewed and the peak occurred at an RH around about 90–95% or even higher. This indicated that high RH values are frequent in Poland. In the majority of the stations, an increase in the average number of hours per year above high percentiles of RH (95, 96th, 97th, 98th, 99th and 99.5th) and an increase in the average number of hours per year below low percentiles of RH (0.5th, 1st, 2nd, 3rd, 4th and 5th) were seen in the period 2008–2020 compared to that in the period 1995–2007. The above findings lead to the conclusion that occurrences of low and high extremes of RH have increased though the average of RH shows a decline. Also, in the majority of the stations, the number of hot–humid hours and the number of cold–dry hours have increased in the period 2008–2020 compared to those in the period 1995–2007. According to the Discomfort Index, over the period 1995–2020, the outdoor warm thermal comfort in Poland has declined due to high temperature and high humidity.
