Strategies to combat climate change may be based on mitigation of the phenomenon or on adaptation to its consequences. This paper aims to identify the driving factors of the choice between these two categories of strategies in the context of urban climate plans. The fight against climate change being characterized by a logic of free riding, the situation tilts the balance towards adaptation strategies in an urban context, to the detriment of mitigation. This hypothesis is tested here through a review of the existing literature on urban climate strategies. This study shows that, counterintuitively, mitigation prevails over adaptation in urban climate strategies up to now. This paper explores the explanations for this seemingly paradoxical situation. We argue that a big part of the explanation has to do with the institutional context of urban climate strategies, specifically the decision-making capacities of municipalities, or the fact that they take part in international networks promoting mitigation over adaptation. Other explanations rely on the cost/benefit impact of adopting mitigation or adaptation, like the collateral local/private benefits of urban climate strategies that are often bigger with mitigation than adaptation. Another finding is that there is no systematic planning making it compulsory to choose between mitigation and adaptation strategies, as they are in some instances complementary, providing co-benefits.

When climate change became a global concern in the 1980s, mitigation was considered the best strategy to address all challenges. For a long time, it was thought possible to stabilize atmospheric concentrations of greenhouse gases (GHGs), which, according to many experts, brought on an unfit adaptation. There are international agreements designed to significantly reduce CO2 emissions and achieve carbon neutrality by 2050, but the policy measures taken so far are insufficient to achieve this goal. In addition, the crisis caused by the COVID-19 pandemic highlighted the relevance of placing this issue at the core of international policies and the need for bottom-up measures and options. The purpose of this paper is to explore how collaborative planning can contribute to adapting the urban tourism sector to climate change in the Porto Metropolitan Area (PMA), located in the northern region of mainland Portugal. In this investigation, we used mixed methods based on the following: (1) the discussion of urban tourism's adaptation planning to climate change with undergraduate students; (2) the application of a modified Delphi questionnaire survey, to 47 international researchers and technicians in the first round and 35 international researchers and technicians in the second round, about the predictability of the adaptation measures; and (3) a theoretical-practical workshop aimed to discuss the main action intentions and ways of adaptation in the short and medium term. All empirical data were collected during the year of 2021. This research highlights the need for more detailed information, the weak interaction between stakeholders and the limitation of resources. Our research identifies the main impacts and local vulnerabilities and determines priorities for adaptation and implementation of actions, aimed at mitigating the effects of climate change and maintaining tourism attractiveness in urban areas. In addition, this investigation allowed the definition of a research agenda, which seeks to guide the area of tourism climatology regarding the new challenges imposed by the COVID-19 pandemic.

Bumblebees are ubiquitous, cold‐adapted eusocial bees found worldwide from subarctic to tropical regions of the world. They are key pollinators in most temperate and boreal ecosystems, and both wild and managed populations are significant contributors to agricultural pollination services. Despite their broad ecological niche at the genus level, bumblebee species are threatened by climate change, particularly by rising average temperatures, intensifying seasonality and the increasing frequency of extreme weather events. While some temperature extremes may be offset at the individual or colony level through temperature regulation, most bumblebees are expected to exhibit specific plastic responses, selection in various key traits, and/or range contractions under even the mildest climate change. In this review, we provide an in‐depth and up‐to‐date review on the various ways by which bumblebees overcome the threats associated with current and future global change. We use examples relevant to the fields of bumblebee physiology, morphology, behaviour, phenology, and dispersal to illustrate and discuss the contours of this new theoretical framework. Furthermore, we speculate on the extent to which adaptive responses to climate change may be influenced by bumblebees' capacity to disperse and track suitable climate conditions. Closing the knowledge gap and improving our understanding of bumblebees' adaptability or avoidance behaviour to different climatic circumstances will be necessary to improve current species climate response models. These models are essential to make correct predictions of species vulnerability in the face of future climate change and human‐induced environmental changes to unfold appropriate future conservation strategies.
