Anthropogenic climate change is a significant driver of disasters, such as tropical storms, floods, drought and loss of biodiversity, amplifying their frequency and severity worldwide. The annual incidence of extreme weather-related events increases with growing human exposure to risks. The Sendai Framework and its associated Sustainable Development Goals (SDGs) recognise the interlinkages between disaster risk reduction, climate change adaptation and sustainable development. However, despite the best intentions of disaster planners, the current efforts are suboptimal in promoting implementation. Education is a critical goal to achieve sustainable development. Environmental Education for Sustainable Development (ESD) seeks to equip students with the knowledge, skills, values and agency necessary to address the complex challenges of climate change and global warming. One example of such an educational programme is the “Speak to Me in Numbers” programme. This interdisciplinary ESD programme educates 9th graders in SDG-related scientific content through scientific data analysis. It strives to inspire students to develop their agency and become responsible future citizens by taking local climate action to bring about sustainable development in their communities. Empowered young people who become agents that bring about global changes are crucial in the context of the climate crisis. However, such efforts should be undertaken cautiously to avoid doing more harm than good by evoking climate anxiety. These implications are discussed.

This essay explores ways in which environmental educators might break with their existing traditions of research and pedagogy by critically appraising climate histories and anticipated futures depicted by SF (science/speculative fiction) in print and audio-visual media. SF has engaged the politics of climate change for at least two centuries and, as a form of public pedagogy accessible to all generations, provides alternative visualisations of the problems arising from humanity’s destructive transformations of Earth’s climate and possible ways of ameliorating them.

Climate change litigation is developing rapidly and pervasively, emerging as a space for legal innovation. Until now, this process has occurred mainly in national courts. The result is a decentralization of the interpretation of human rights relating to climate change. This article argues that such decentralization could, in principle, have a destabilizing impact on claims to the universality of human rights. However, close examination of this litigation shows that a prototype is emerging, certain features of which are becoming ‘hard wired’ through the process of judicial dialogue. By exploring the content of this prototype, its decentralized development, and its self-reinforcing nature, we see a legal space emerging in which environmental human rights sit between the universal and the contextual.

Several experimental tools allow researchers to manipulate environmental variables to simulate future climate change scenarios during in situ seed ecology studies. The most common ones are designed to modify a single environmental variable. For example, open-top chambers (OTCs) increase temperature or rain-out shelters decrease precipitation. However, changes in environmental variables in the future are expected to happen simultaneously, and at present, an understanding of their combined effects in natural environments is limited. Here, we present a passive novel OTC design that simultaneously increases the soil temperature and decreases soil moisture. We assessed the performance of the design during 1 year in a high-mountain environment and reported its effects on the organic and topsoil layers. The modified OTC reduced the soil volumetric water content throughout the study period. Overall, chambers increased the mean day air temperature by 3.3 °C (at 10 cm above the soil surface), the mean day soil surface temperature by 1.35 °C and the mean day below the soil surface temperature by 1.30 °C (at −5 cm) and 1.25 °C (at −10 cm). Remarkably, surface and soil temperatures remained warmer at night (+0.65 at soil surface, +0.41 at −5 cm and +0.24 at −10 cm). We detail the design plans, tools and materials needed for its construction. Furthermore, we recommend on how to use it during seed ecology studies. This tool can help increase our understanding of the potential responses of seeds and seedlings to the combined effects of warming temperatures and a decrease in precipitation.

Tidal flooding occurs when coastal water levels exceed impact-based flood thresholds due to tides alone, under average weather conditions. Transitions to tidal flood regimes are already underway for nuisance flood severities in harbours and bays and expected for higher severities in coming decades. In the first such regional assessment, we show that the same transition to tidally forced floods can also be expected to occur in Australian estuaries with less than 0.1 m further sea-level rise. Flood thresholds that historically used to only be exceeded under the combined effects of riverine (freshwater) and coastal (salt water) influences will then occur due to high tides alone. Once this tidal flooding emerges, it is projected to become chronic within two decades. Locations most at-risk of the emergence of tidal flooding and subsequent establishment of chronic flood regimes are those just inside estuary entrances. These locations are exemplified by low freeboard, the vertical distance between a flood threshold and a typical high tide level. We use a freeboard-based analysis to estimate the sea-level rise required for impacts associated with official flood thresholds to occur due to tides alone. The resultant tide-only flood frequency estimates provide a lower bound for future flood rates.

Rock glaciers support alpine biodiversity and may respond more slowly to warming than snow or glaciers. While responses of snow and glaciers to climate change are relatively well understood, a robust assessment of rock glacier environmental niche, future distributions of rock glaciers and potential for development of rock glaciers from current glaciers is lacking. Using process-relevant, high-resolution environmental descriptors, we develop a species distribution model of the topographic, geologic and hydroclimatic niche of rock glaciers that provides novel estimates of potential rock glacier distributions for different climates. We identify mean annual air temperature and headwall area as the dominant controls on rock glacier spatial distributions, with rock glaciers more likely to be found in areas with mean annual temperatures close to −5°C, little rain, northern aspects and broad headwalls. While rock glacier climate equilibration may take hundreds of years, we find that equilibration to present climate will result in a 50% reduction in rock glacier habitat and equilibration to late 21st-century climate under a high-end warming scenario will result in a 99% reduction in rock glacier habitat across the western USA. Under future conditions, we find limited potential for glacier to rock glacier transformation (3% of glacierized area), concentrated in cold, high elevation, moderate precipitation areas.

The available choices of political responses to disruption in the global climatic system depend in part on how the problem is conceptualized. Researchers and policymakers often invoke a “climate crisis” or “climate emergency,” but such language fits poorly with current knowledge of the problem's physical causes and social impacts. This article argues that climate change is instead more like a political epic. It involves neither sudden onset, as in the concept of emergency, nor decisive resolution, as in the concept of crisis, but rather a protracted ordeal of (temporally) obscure origins and uncertain outcomes. This alternative ontology of climate change highlights its novel temporal properties, including unusually slow-moving or time-lagged causal dynamics, with unsettling implications for academic research on the climatic-institutional nexus. Normatively, it undermines arguments for democracies’ environmental superiority over autocracies that rely on the former's general superiority at resolving crises and responding to emergencies. At the same time, some new arguments for democratic distributions of power become possible within the epic frame. More broadly, embracing the assumption of epic climate change may redirect attention from Promethean, managerial, or technocratic solutions to questions about which values or identities deserve preservation amid presumptively interminable and imperfectly remediable sources of disorder.

The public trust doctrine holds promise as a tool for combatting international climate inaction. A global public trust in the Earth’s atmosphere may be a feasible avenue for generating international cooperation in this issue. The public trust doctrine is a viable and underutilized mechanism of understanding our collaborative obligations with respect to natural resources. This Article looks to the historical origins and current presentations of public trusts to extract features which indicate its effectiveness and appeal for modern climate change applications. Additionally, it presents two circumstances under which a global public trust in the atmosphere could eventually develop.

Anthropogenic-mediated climate change is expected to negatively affect pest management in agriculture. Hence, we investigated the oviposition, immature mortality, and developmental processes of Spodoptera species (Spodoptera exigua (Hübner) and Spodoptera litura (Fabricius)) under different temperatures (20, 25, and 30°C) and relative humidity (RH) (30–35, 50–55, 70–75, and 90–95%) conditions. For fecundity, mouths of each Spodoptera species were released into a rectangular box whose inner walls were covered with a sheet of white paper for each combination of temperature and RH. The mouths were kept inside the box to deposit eggs for 72 h. Temperature and RH significantly affected the fecundity, with the maximum number of eggs laid in 70–75% at 30°C. The highest egg and larval mortalities were recorded in 30–35 and 90–95% RH, respectively. Temperature and RH greatly affected the developmental period (egg–adult) and adult emergence rate. The rapid development was recorded in 70–75% RH at 30°C. Higher number of adults was found with an increase in temperature and RH. Adult longevity was significantly higher in 70–75% RH at 20°C. Based on the present study's findings, temperature and RH had an individual apparent effect on the developmental processes of Spodoptera species instead of an interactive effect. Therefore, there is need for an in-depth study of the influence of several climatic factors, including CO2, on the developmental modality and demographic changes of Spodoptera species to assess the impacts of climatic components and the sustainable development of management strategies.

Global warming is exposing many organisms to severe thermal conditions and is having impacts at multiple levels of biological organisation, from individuals to species and beyond. Biotic and abiotic factors can influence organismal thermal tolerance, shaping responses to climate change. In eusocial ants, thermal tolerance can be measured at the colony level (among workers within colonies), the population level (among colonies within species), and the community level (among species). We analysed critical thermal maxima (CTmax) across these three levels for ants in a semiarid region of northeastern Brazil. We examined the individual and combined effects of phylogeny, body size (BS), and nesting microhabitat on community-level CTmax and the individual effects of BS on population- and colony-level CTmax. We sampled 1864 workers from 99 ant colonies across 47 species, for which we characterised CTmax, nesting microhabitat, BS, and phylogenetic history. Among species, CTmax ranged from 39.3 to 49.7°C, and community-level differences were best explained by phylogeny and BS. For more than half of the species, CTmax differed significantly among colonies in a way that was not explained by BS. Notably, there was almost as much variability in CTmax within colonies as within the entire community. Monomorphic and polymorphic species exhibited similar levels of CTmax variability within colonies, a pattern not always explained by BS. This vital intra- and inter-colony variability in thermal tolerance is likely allows tropical ant species to better cope with climate change. Our results underscore why ecological research must examine multiple levels of biological organisation.

This Article examines scenario analysis, a disruptive argumentation technique used by the German Federal Constitutional Court (GFCC) in recent high-profile cases, such as the so-called climate protection case (Klimaschutz) and other decisions on the fundamental right to intergenerational justice (Grundrecht auf Generationengerechitgkeit). After explaining the basic argumentative steps involved in scenario analysis, for example designing scenarios, identifying stakeholders, relating scenarios to strategies, determining the main driving forces, estimating scenario probabilities, the Article sketches a normative model for rational scenario design. The normative model is used as a lens for evaluating the arguments developed by the GFCC in the climate protection case. Such evaluation also builds on game-theoretic insights and points out some weaknesses in the Court’s argument. Finally, the Article observes that, as scenario analysis is used to assess the future impact of legislative decisions, it has the effect of imposing greater constraints on legislatures.

Climate change is responsible for marked increases in the frequency and severity of bush/wildfires, resulting in more people exposed to such events with long-term subclinical psychiatric symptoms. This editorial calls for immediate action to implement comprehensive and novel approaches to treating these conditions and preventing them from developing into more severe disorders.

Climatic conditions have changed within the cloud forests of southern Mexico, but the effects of these changes on tree phenology are not well understood. Our study aimed to determine relationships between seasonal patterns of flowering and fruiting and the annual and long-term changes in temperature and rainfall in El Triunfo Biosphere Reserve, Mexico. Flowering and ripe fruiting intensity and fruit number were recorded for 158 trees of 21 zoochorous species during 17 months in 2019–2021. Circular statistics, synchronization calculations, and generalized linear mixed models were used to determine phenological patterns and relationships between phenophases and temperature, rainfall, and solar radiation. Flowering was most closely associated (negatively) with rainfall, whereas ripe fruiting was positively associated with solar radiation. We compared recent fruiting seasonality with phenological data collected in 1991–1993. The mean date of community fruiting in 2019–2020 was earlier (April 4) than in 1992 (May 1) and 1993 (May 13). Community fruit number in 2020–2021 decreased in comparison to 2019–2020. Our results suggest that decadal trends of increasing minimum daily temperature and an earlier and wetter wet season influenced the timing of community fruiting phenology, and fruit numbers varied greatly between years, possibly impacting resource availability for frugivores in El Triunfo.

Politics in environmental education is conspicuous by its absence. This article is a plea to make politics–the study of who gets what, when, and how–central to our field and the keystone of a better way forward.

Climate change stands as the paramount challenge confronting humanity in the contemporary era. Attempting to address the problem, the main sectors responsible for it have been subject to domestic or international policies and laws aimed at reducing greenhouse gas (GHG) emissions, except one: livestock. Given that animal-sourced food production contributes a large portion of GHG emissions, this Article aims to analyze the impacts that the exclusion of the livestock sector, in efforts to tackle climate change, would have on compliance with international treaties on the subject, especially the Paris Agreement. One conclusion reveals that state parties, by ignoring the sector, will violate several articles of the Agreement, which will likely lead to the failure of its main purpose of holding the increase in the global average temperature to well below 2°C.

Climate change is no longer a problem for future generations and the impact is already taking a toll in many parts of the world. Climate change has already caused substantial, and increasingly irreversible, damage to ecosystems. All these issues combined will inevitably lead to an increase in human suffering and forced displacement. This has significant ramifications for health care systems. In this editorial we outline how climate change is already impacting both physical and mental health. Health professionals have a role to play in addressing this great challenge of our time. Health professionals should reflect on how to promote means of climate change mitigation and adaptation within their spheres of influence – clinical, education, advocacy, administration, and research.
