Comparison of temporal variability in temperature between an Arctic region (Kenestupa, Finland, 67.696° N, 27.185° E) and a tropical hyperdiverse region (Manu National Park, Peru, 11.793° S, 71.519° W). Here, a coupled meso‐ and microclimate model was used to derive hourly temperatures for the period 1970–2019 (Finland: 50 cm above ground in 25‐cm‐tall Arctic tundra, model from Kearney et al., 2020; Peru: 15 m above ground, below 20‐m‐tall tropical broadleaf forest, model from Maclean, 2019). Hourly temperatures are far less variable in Peru, ranging by c. ± 10°C from the annual mean, in comparison to Finland, where temperatures fluctuate by ± 25°C from the annual mean, implying that species in tropical hyperdiverse regions might be less suited to tolerating changes in temperature. Moreover, despite considerably greater warming in Finland (1.713°C) in comparison to Peru (0.864°C), inter‐annual variability in the mean annual temperature is greater in Finland and, in consequence, the recent (1995–2019) temperatures in Peru are at least as novel as those in Finland.
