Scientists have long warned about the severe environmental consequences if global temperatures continue to rise. According to the 2021 IPCC report, the Earth's temperature has increased by 1.1°C above preindustrial levels, and the world is projected to exceed 1.5°C within two decades, even with emission reduction efforts. International initiatives, starting with the 1992 UNFCCC and the 1997 Kyoto Protocol, laid the groundwork for climate action. The 2015 Paris Agreement, a pivotal moment, set a goal to limit warming to below 2°C, ideally 1.5°C, through nationally determined contributions (NDCs). Addressing climate change requires systemic shifts in economic structures, moving away from fossil fuels toward renewable energy, promoting decarbonization, and emphasizing resource efficiency. While transitioning to a low-carbon economy poses initial costs, the long-term benefits include reduced environmental damage, better health, and enhanced energy efficiency. The ongoing global cooperation and economic transformation are crucial for mitigating climate change impacts.

Human activities have caused significant changes in the climate system, leading to more frequent and intense extreme weather events such as heatwaves, droughts, and tropical cyclones. Global warming poses escalating risks, with even a 1°C –2°C increase above preindustrial levels disrupting ecosystems and threatening coral reefs, polar ice caps, and species. Beyond 3°C, the impacts are expected to turn catastrophic, risking ecological collapse and mass displacement. Climate change also introduces severe physical risks to economies by damaging infrastructure, disrupting agriculture, and increasing costs related to property damage and healthcare. Rising sea levels threaten coastal areas, while extreme weather events fuel price increases and food shortages. Despite challenges in quantifying these economic impacts, interdisciplinary research and advanced modeling aim to enhance assessment accuracy. Urgent global action is required to mitigate climate change and protect ecosystems and economies from irreversible damage.
Why do we want to transition all of our energy to clean, renewable energy? Why don’t we just continue burning fossil fuels until they run out, which may be in 50 to 150 years? For three major reasons. Namely, fossil fuels today cause massive air-pollution health damage, climate damage, and risks to the world’s energy security. These three problems, which have the same root cause, require immediate and drastic solutions. The longer we wait to solve these problems, the more the accumulated damage. This chapter examines each problem, in turn.

The increased salience of environmental concerns, first and foremost global warming, is one of the key developments of contemporary Western European politics. Still, the effects of global warming issues on electoral outcomes, party competition and polarization remain poorly understood. Our article shows how the construction of wind turbines fuels conflict between its key proponents and opponents, Green and populist radical right parties. Contention over the issue contributes to the electoral success of both sides and therefore reinforces the new central divide between them. Drawing on a novel dataset, we investigate the impact of the construction of wind turbines on Alternative für Deutschland and Green party electoral success in Germany. We employ a two‐way fixed effects model, where the construction of wind turbines functions as the independent variable. We show that the construction of wind turbines boosts the electoral support of both their biggest supporters and their biggest opponents. Our results have important implications for understanding contemporary political conflict in Western Europe such as the electoral rise of the Greens and the populist radical right, the importance of issue salience and the polarization of party systems.
Over the past 20 years, the US Federal Government has been considered to be intransigent in its response to climate change by many commentators and not-for-profit environmental advocacy organizations (nonprofits). An enduring source of pressure on the US Government has been nonprofit campaigns operating at both a state and federal level. Six US environmental nonprofits representing a diversity of resources and prominence were selected for an in-depth examination of their climate-focused campaigns. Given the resistance at the federal level, these nonprofits have undertaken state-focused campaigns to achieve adequate climate policy development. This research examined some climate campaigns in California by the selected nonprofits that have supported, enhanced, and influenced the Californian Government’s efforts to address climate change. The campaigns have gained leverage from existing state competition for economic advancement and political leadership on issues of public concern. In addition, they appear to have benefited from a high level of environmental awareness in the community, a history of progressive environmental legislation, Governor Schwarzenegger’s use of climate change to differentiate his political leadership, and strong public trust of nonprofits. Recent climate-related political pledges and legislative changes at a federal level are convergent with the nonprofit-influenced, state-level developments.
This paper compares climate change campaigns conducted by environmental nongovernment organizations (NGOs) in the United Kingdom (UK) and Australia. The NGOs represent a diversity of political access, financial resources, and international connections. Three campaign activities common to both countries undertaken between 2004 and 2006 are analyzed for their effectiveness via interviews and document review. This examination is embedded within an analysis of the political, economic, policy, and social contexts of each country. It is shown that in the UK climate change has been used as a pivotal leadership issue, that the fossil fuel industry’s influence is not predominant, and that NGOs enjoy political legitimacy. Whereas, in Australia climate change has only recently emerged as a political priority, the fossil fuel industry has had significant political and financial influence, and NGO advocacy has been marginalized. It is argued that NGOs are embedded in the political and policy contexts of their country, and the greatest campaign traction and NGO influence can only be achieved when these contexts provide favorable conditions.
The Dwarka Basin in the Kathiawar Peninsula, western margin of the Indian subcontinent, offers crucial insights into marine sedimentation processes and faunal evolution during the Miocene epoch. This research employs a combination of biostratigraphy, microfacies analysis and geochemical data to examine the Gaj Formation, a major stratigraphic unit of the Dwarka Basin, with the aim of reconstructing the paleoclimatic and depositional conditions. Foraminiferal biostratigraphy suggests that the Gaj Formation ranges from the Aquitanian to the Langhian stage, with the intermediate Burdigalian stage comprising most of the succession. Microfacies analysis reveals that the formation was primarily deposited in shelf environments, influenced by regional tectonic and climatic factors. The fossil assemblages and morphological adaptations observed in foraminiferal shells provide clear evidence of the Middle Miocene Climatic Optimum (MMCO). Climate-driven global warming during this climatic phase caused morphological evolution (e.g., dwarfism) and decreased faunal diversity in response to environmental stress. This study also aims to reconcile discrepancies in stratigraphic classification in the basin through lithostratigraphic data and high-resolution faunal analyses. Results highlight the dynamic nature of marine depositional environments as impacted by global sea-level changes, regional tectonics and climatic fluctuations. The study foregrounds the importance of multi-proxy analyses in reconstructing complex depositional histories and Miocene climatic transitions and their effects on regional marine ecosystems.
Written by an established climate change scientist, this book introduces readers to cutting-edge climate change science. Unlike many books on the topic that devote themselves to recent events, this volume provides a historical context and describes early research results as well as key modern scientific findings. It explains how the climate change issue has developed over many decades, how the science has progressed, how diplomacy has (so far) proven unable to find a means of limiting global emissions of heat-trapping substances, and how the forecast for future climate change has become more worrisome. A scientific or mathematical background is not necessary to read this book, which includes no equations, jargon, complex charts or graphs, or quantitative science at all. Anyone who can read a newspaper will understand this book. It is ideal for introductory courses on climate change, especially for non-science major students.
Environmental security broadly refers to the relationships between the environment and national, human, and ecological security. This encompasses how environmental changes affect or interact with violence, armed conflict, state stability, livelihoods, food security, economic stability, general human well-being, and more. This chapter unpacks environmental security by focusing on how environmental change and disaster impact humans, states, and the international order, respectively. Although many security studies scholars still question whether the environment should be considered a security issue or just a pressing policy issue, this chapter demonstrates the serious security issues that arise with the onset of environmental change. Regardless of the outcome of these academic debates, these challenges are very real for policy makers, who are working to anticipate and manage the challenges that the environment will pose to international security.
Chapter 2 provides a primer on climate science for legal practitioners and scholars, and it offers essential scientific background to help readers understand the context of climate litigation. Based on reports of the latest (sixth) assessment cycle of the Intergovernmental Panel on Climate Change, the authors begin with an overview of the components of the climate system, the carbon cycle, and the greenhouse gas effect. The second section looks backwards to show the influence that humans have had on climate change to date, while the third section focuses on the current impacts of climate change. The fourth section looks forward and presents future emissions scenarios and projected warming and impacts, highlighting both fast and slow onset climate changes. The final section evaluates progress toward the goals set in the Paris Agreement and explores strategies for stabilising global temperatures.
Studies on the evolution of characteristics and dynamic mechanisms of dry/wet status in global arid regions are contradictory. We systematically assessed the evolution and drivers of dry/wet status in global arid regions from a paleoclimate perspective using observational datasets, paleoclimate records, and climate model simulations from Paleoclimate Model Intercomparison Project Phase 4 (PMIP4)-Coupled Model Intercomparison Project Phase 6 (CMIP6) and PMIP3-CMIP5. Our results show that climate change during the last glacial maximum (LGM) provides a reverse analog for the near-future climate in global arid regions. The notable migration of the subtropical high during the LGM profoundly altered the atmospheric circulation and influenced dry/wet status in global arid regions. The multimodel ensembles project that under the shared socioeconomic pathway (SSP) 8.5 scenario, nonuniform heating induced by polar-amplified warming will introduce northward migration of the subtropical high. The resulting reduction in subtropical precipitation will lead to expansion of global arid regions under global warming, which is consistent with previous studies based on atmospheric aridity.
Following the Great East Japan earthquake, tsunami and nuclear disaster of 11 March 2011, the Japanese government began constructing a series of 440 seawalls along the north-eastern coast of Honshu. Cumulatively measuring 394.2km, they are designed to defend coastal communities against tsunami that frequently strike the region. We present a case study of the new seawall in Tarō, Iwate Prefecture, which had previously constructed massive sea defences in the wake of two tsunami in 1896 and 1933, which were subsequently destroyed in 2011. We ask whether the government has properly imagined the next disaster for the era of climate change and, therefore, whether its rationale for Tarō‘s new seawall is sufficient. We argue that the government has implemented an incremental strengthening of Tarō‘s existing tsunami defence infrastructure. Significantly, this does not anticipate global warming driven sea level rise, which is accelerating, and which requires transformational adaptation. This continues a national pattern of disaster preparedness and response established in the early 20th century, which resulted in the failure to imagine the 2011 tsunami. We conclude by recalling the lessons of France's Maginot Line and invoke the philosophy of Tanaka Shōzō, father of Japan's modern environmental movement, who urged Japanese to adjust to the flow (nagare) of nature, rather than defend against it, lest they are undone by the force of its backflow (gyakuryū).
Dolichousnea longissima is famous as the world’s longest lichen, which typically reproduces asexually. Factors impacting its length and reproductive strategies are of theoretical interest and important for conservation. We discovered a Dolichousnea population with apotheciate thalli in Western China. Phylogenetic analyses using ITS sequence data confirmed specimens were D. longissima. Multiple phylogenetic branches included both apotheciate and non-apotheciate thalli, thus genetic differences within the ITS region were not related to apothecia production. There was no indication that apotheciate Dolichousnea specimens from this region belong to a separate, morphologically and genetically distinct population. In a field experiment, we transplanted non-apotheciate thallus strands of 10, 20, 40 or 80 cm length from higher to lower elevations: c. 4000 to 3400 m. Elevational gradients in temperature, relative humidity and vapour pressure deficit simulated future climatic change. We tested hypotheses regarding the impact of climatic stressors on D. longissima growth and reproduction. After three years of growth, thallus mortality was highest at the lowest sites. Of surviving thalli, 23% had fragmented, with fragmentation rates increasing with length. Other thalli thrived, reaching a maximum main stem length of 321 cm, with a maximum total length of 764 cm. Intact thalli showed negative length-dependent growth. Lower elevations were associated with initiation of sexual reproduction, reduced relative thallus length growth rates (RTLGR) and lower photobiont abundance, with apparent shifts of photobionts from the main stem to fibrils and reallocation of resources from length to central cord and fibril mass. Probability of switching to sexual reproduction increased with thallus length, but shorter thalli made greater relative investment in apothecia production. Detrimental impacts of climate change could reduce D. longissima range and biomass production, thereby also decreasing food availability for the endangered lichenivorous monkey, Rhinopithecus bieti. Conservation efforts should be prioritized at sites currently hosting abundant, fast-growing thalli, and high-elevation mature forests where D. longissima is most likely to persist under future climatic change. Apotheciate populations need protection because sexual reproduction theoretically generates genetic variability, increasing the likelihood of generating mycobiont genotypes adapted to altered climatic conditions.
A specimen of Prionotus punctatus was caught in Bahía Engaño, Chubut Province, Patagonia, Argentina. This extends the known distribution by 900 km and a 5.5° further south from its previous southernmost record. This record increases the number of species of the genus Prionotus and the fish diversity of central Patagonia. The presence of P. punctatus along with other recent reports of fish of tropical and subtropical lineages in central Patagonia adds new evidence on the ongoing tropicalization of the Patagonian Sea.
The causes of climate change are largely due to the carbon emission activities of nation states and transnational corporations. This chapter considers these activities as crimes of the powerful, a form of ecocide, insofar as they contribute to global warming. In addition to exploring the contours of ecocide as a crime, the chapter deals with issues pertaining to contrarianism and the exploitation of natural resources, both of which protect and sustain sectional private interests rather than the majority public interest. The chapter argues that needed social transformations must go beyond “speaking truth to power” to actually confront the powerful. How this might be accomplished is examined through consideration of green capitalism, the movement toward just transitions, the idea of a Green New Deal, and the importance of transformational nationalisation. Combatting the violence of ecocide fundamentally requires root and branch change in the global political economy.
Crowdsourcing platforms—such as Vivino—that aggregate the opinions of large numbers of amateur wine reviewers represent a new source of information on the wine market. We assess the validity of aggregated Vivino ratings based on two criteria: correlation with professional critics’ ratings and sensitivity to weather conditions affecting the quality of grapes. We construct a large, novel dataset consisting of Vivino ratings for a portfolio of red wines from Bordeaux, review scores from professional critics, and weather data from a local weather station. Vivino ratings correlate substantially with those of professional critics, but these correlations are smaller than those among professional critics. This difference can be partly attributed to differences in scope: Whereas amateurs focus on immediate pleasure, professionals gauge the wine’s potential once it has matured. Moreover, both crowdsourced and professional ratings respond to weather conditions in line with what viticulture literature has identified as ideal, but also hint to detrimental effects of global warming on wine quality. In sum, our results demonstrate that crowdsourced ratings are a valid source of information and can generate valuable insights for both consumers and producers.
This chapter goes beyond the description of individual events by covering extremes caused by a combination of multiple events. Two main types of interactions are covered: domino effects and compound events. Domino effects, which represent one-way chains of events, are quantified using Markov theory and graph theory. Compound events, which include complex feedback loops in the complex Earth system, are modelled with system dynamics (as in Chapter 4). Two such systems are provided, the ESCIMO climate model and the World2 model of world dynamics. The impact of global warming, pollution, and resource depletion on catastrophes is investigated, as far as ecosystem and societal collapse. The types of catastrophes considered in this chapter are as follows: storm clustering, earthquake clustering (with accelerated fatigue of structures), domino effects at refineries (explosions, fires, toxic spills), cascading failures in physical networks (more precisely blackouts in a power grid), rainforest dieback, lake eutrophication, and hypothetical human population collapse.
Climate change is a global challenge to ecosystem services, altering crop yields and food security worldwide. In the context of climate change, Onobrychis viciifolia Scop. (sainfoin) can offer a multitude of ecosystem services conferred by its multifaceted beneficial properties. We reviewed the morphological, biochemical and physiological responses to environmental stressors of O. viciifolia, summarized its ecological, agronomic, nutritional and biological interests, and we discussed its use under climate change. Onobrychis viciifolia is a hemicryptophyte forage legume adapted to arid and semiarid regions by evolving a diverse array of protective mechanisms against abiotic stressors at morphological, biochemical and physiological levels. In the present scenario of climate change, O. viciifolia has desirable forage characteristics such as high nutritive value, high voluntary intake and palatability to grazing animals, leading to satisfying animal performance for milk, meat, honey and wool production. Recent studies suggest that O. viciifolia has several highly beneficial phytochemical properties including condensed tannins and polyphenol content, which have been demonstrated to have anthelmintic activities, enhance protein utilization, and prevent bloating. In addition, O. viciifolia also has the potential to reduce greenhouse gas emissions and sequestrate atmospheric carbon and nitrogen into the soil. Ethnobotanical investigations show that O. viciifolia possesses antimicrobial, antiseptic and vulnerary activities. This review could be helpful for understanding of O. viciifolia characteristics, interests and uses, thus promoting its reasonable cultivation under a changing climate.
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.
