Introduction
Humanity finds itself at a critical crossroads, confronted by an unparalleled challenge demanding immediate attention and action. Climate change, a crisis largely fueled by human activity, is rapidly intensifying, posing a grave threat to global stability and jeopardizing centuries of advancement [1].
The latest Intergovernmental Panel on Climate Change (IPCC) report acknowledges the interconnectedness of climate, ecosystems, biodiversity, and human societies, emphasizing diverse knowledge sources and the ties between climate action, ecosystem health, human well-being, and sustainable development [2]. Human activities, particularly greenhouse gas emissions, have undeniably driven global warming, with temperatures surpassing 1.1°C above pre-industrial levels. Unequal contributions to emissions stem from unsustainable energy and land use practices, impacting regions and communities differently [3]. Significant changes across various natural systems are attributed to human-induced climate change, leading to widespread adverse effects and disproportionate, inequitable impacts on vulnerable communities. For example, the Pacific Islands, despite having a minimal carbon footprint, are facing the brunt of climate change impacts, exemplifying the severe inequities inherent in this global crisis [4,5]. Continued emissions will further warm the planet, intensifying hazards, while prompt emissions reductions could slow warming within two decades. Projected risks surpass previous assessments, escalating with each degree of warming, compounded by interacting climatic and non-climatic factors. Changes such as the loss of Arctic sea ice, the melting of glaciers, and the thawing of permafrost may be irreversible, necessitating urgent and sustained mitigation actions to limit impacts [6].
Achieving net zero CO2 emissions is crucial for limiting warming to 1.5°C or 2°C, requiring rapid and substantial emissions reductions across all sectors. Overshooting temperature targets poses additional risks, necessitating sustained negative emissions. Climate change poses a severe threat to human well-being and necessitates immediate, coordinated action to secure a sustainable future. Early mitigation and adaptation efforts promise numerous benefits, while delayed action risks irreversible damage and financial burdens [7].
Urgent transitions in all sectors are vital for sustainable development, with feasible options available albeit varying by context. The scenarios we face under the umbrella of ‘climate change’ are diverse and daunting, each carrying a pressing need for action. Will we navigate the growing conflicts over resources as climate change undermines our food systems [8]? How will we adapt to and manage the large-scale human displacements triggered by environmental catastrophes, potentially the most significant migration events in history [9]? Amidst these challenges, we must also consider the potential impacts on the fundamental principles of the Universal Declaration of Human Rights [10]. Prioritizing equity and social justice can enhance adaptation and mitigation outcomes, while effective governance, finance, and technology are essential enablers for climate action. Scaling up financing and technological innovation, alongside enhanced international cooperation, are critical for achieving climate goals [11].
Aim of the work
The aim of this work is to critically assess and synthesize strategic interventions across six identified domains crucial for mitigating the climate crisis and steering society towards a sustainable future. These domains are: (1) reinventing food systems, (2) preparing for population shifts, (3) upholding human rights, (4) investing in clean energy, (5) educating for a climate-conscious society, and (6) securing financial and political support. Unlike the methodological focus on delineating the climate crisis’s impacts on food security, migrations, and human rights, this work sets out to evaluate the efficacy of multifaceted strategies—ranging from technological innovations in food systems and energy to policy frameworks for human rights protection and climate education. By mapping out the intersections between these areas, we aim to reveal the integrative efforts necessary for a coherent response to climate challenges. The objective of this paper is to propose a blueprint for collective action and policy-making that encapsulates the complexity and interconnectedness of global climate solutions, grounded in actionable insights and fostering global collaborations that align with the urgent need for resilience and sustainability in the face of climate change.
Methods
In this narrative communication, we used a comprehensive summary of existing research delineating six critical pathways for addressing the climate crisis: (1) reinventing food systems, (2) preparing for population shifts, (3) upholding human rights, (4) investing in clean energy, (5) educating for a climate-conscious society, and (6) securing financial and political support. We focused on areas with extensive implications for global stability and human welfare. Although other consequences like biodiversity loss are indisputably critical, these chosen pathways are deemed to exert the most immediate and profound impacts on humanity’s trajectory in a climate-constrained future. Food security is vital for human survival and may precipitate geopolitical tensions. Climate-induced migrations present significant challenges to international cooperation, urban planning, and social unity. Lastly, the erosion of human rights amidst climate pressures could fundamentally reshape societal frameworks [12]. The findings were thematically categorized and presented, synthesizing existing knowledge and identifying broader trends, patterns, and gaps in the literature [13].
Literature review results
The results of the review were divided into emerging global crises concerning climate change, and the possible solutions. The former describes the identified issues and obstacles, while the latter will discuss different paths, which may resolve the identified problems.
Climate change and emerging global crises
Food wars
Speculations about ‘food wars’ have long circulated, but the specter of climate change threatens to turn this theoretical risk into a harsh reality. Our intricate global food systems heavily depend on stable climates, predictable weather, and diverse ecosystems. However, climate disruptions are upsetting this delicate balance. Global warming, shifting precipitation patterns, and extreme weather events endanger both crop production and livestock health [14]. Rising temperatures may shorten growing seasons and reduce yields from staple crops. Floods and droughts, worsened by climate change, can devastate harvests and livestock. Additionally, the relocation of agricultural regions due to shifting climates could disrupt farming and harm critical ecosystems. The looming threat of marine ecosystem collapses, fueled by ocean acidification and warming, further complicates the situation [14,15].
As food security declines, competition for resources may escalate, potentially triggering conflicts locally and internationally. Urgent action is needed to adapt our food systems, ensure equitable access to food and water, and prevent conflicts. Innovative agricultural practices, resilient supply chains, and fair resource distribution policies are essential [16]. However, recognizing the urgency of climate change’s threat to our food systems is the crucial first step. The crisis of biodiversity loss is closely linked to the looming ‘food wars.’ As ecosystems falter and species disappear, the foundation of agricultural productivity is compromised [17]. Biodiversity supports crop yields by providing essential services like pollination and pest control. Loss of biodiversity directly threatens food security and increases the risk of conflicts over dwindling resources [18]. Understanding this link highlights the complexity of our global ecological system and underscores the need to address biodiversity loss to mitigate food-related conflicts.
Mass climate migrations
Climate change is commonly associated with immediate physical impacts like intensified storms and rising sea levels. However, a slower yet profound consequence is the ongoing mass migrations it triggers. Already underway, this phenomenon is expected to accelerate as climate change effects worsen. Gradual ecological changes from global warming are rendering large areas increasingly uninhabitable. Rising sea levels threaten to submerge low-lying nations and coastal regions, while worsening droughts expand deserts, transforming once-fertile lands [19].
These changes are displacing populations steadily, a trend projected to escalate. Biodiversity loss compounds the issue, as deteriorating habitats and disappearing species weaken ecosystems, making regions more susceptible to climate change. This degradation contributes to desertification and reduced water availability, driving incremental population displacements. Integrating ecosystem protection and restoration into mitigation strategies is crucial to mitigate migration impacts and support climate migrants [20].
These gradual demographic shifts resulting from climate change are expected to affect hundreds of millions, possibly billions, of people over decades. Primarily impacting developing nations, the effects will reverberate globally, influencing social, economic, and political structures [21,22]. To effectively address these changes, adaptive strategies recognizing the gradual nature of climate-induced migrations are necessary. This comprehensive approach must uphold human rights, foster international cooperation, and provide extensive support for the displaced. Understanding and planning for these shifts are vital components of the global response to climate change [23].
Human rights at stake
As the possibilities of ‘food wars’ and mass migrations loom larger, we confront a troubling reality: the potential erosion or disregard of the principles laid out in the Universal Declaration of Human Rights. Climate change imperils more than just our physical environment [24], it also jeopardizes the social, political, and moral foundations of our societies. With dwindling resources and uninhabitable regions, societal tensions could escalate, endangering cherished principles like freedom, justice, peace, and equality [25]. Moreover, the principle of equity is crucial, as climate change disproportionately affects the most vulnerable and marginalized communities, exacerbating existing social and economic disparities. Many indigenous and local communities, whose rights are protected by international declarations, rely deeply on their natural surroundings. The loss of biodiversity jeopardizes their way of life, access to traditional foods, and cultural identity.
History illustrates that crises often lead to the infringement of human rights [26], with restrictions on movement and denial of basic needs becoming commonplace. These threats disproportionately affect the most vulnerable and marginalized. Many indigenous and local communities, whose rights are protected by international declarations, rely deeply on their natural surroundings. The loss of biodiversity jeopardizes their way of life, access to traditional foods, and cultural identity [27].
Addressing these challenges demands a reaffirmation of our commitment to human rights, a reimagining of our societal structures, and a comprehensive approach that acknowledges the interconnectedness of environmental well-being and human rights. Our response to climate change must prioritize preserving human dignity and rights [28,29]. Protecting biodiversity is thus not solely an environmental concern but a matter of upholding human rights, particularly for those most reliant on natural ecosystems.
Charting a course to a sustainable future
In tackling the formidable challenges of climate change, it is crucial to identify and pursue pathways leading us to a sustainable and equitable future. From reinventing global food systems to address sustainability and equity challenges, to preparing for population shifts triggered by environmental changes and upholding human rights in a strained world, each pathway should play a pivotal role. Additionally, the role of clean energy in driving environmental and economic renewal and the power of education in shaping a climate-conscious society are indispensable. These pathways collectively form a multifaceted strategy representing proactive steps toward a future where humanity not only survives but thrives [30,31].
Reinventing food systems
To avert the looming threat of ‘food wars’, we must revolutionize our global food systems, addressing their vulnerability to climate change while striving for resilience and equity. To do so we need to foster resilience, that is to develop agricultural practices that can withstand climate fluctuations. Techniques like permaculture and agroforestry, exemplified by the Ever-Green Agriculture initiative in Malawi, enhance soil fertility and crop yields, bolstering resilience [32]. We also need to embrace technology, i.e., to explore innovations like vertical farming and precision agriculture to produce food in adverse conditions. Singapore’s high-tech urban farms, such as those by Sky Greens, utilize vertical farming to maximize production in limited spaces [33,34].
Furthermore, the food sources should be diversified. To diversify food sources, we need to expand crop and protein varieties to enhance nutritional diversity and reduce reliance on vulnerable crops and livestock. Plant-based and lab-grown proteins, championed by companies like Beyond Meat and Memphis Meats, offer sustainable alternatives [35,36]. Another important step is to use crop wild relatives, which means harnessing the genetic diversity of CWRs to develop resilient and nutritious crop varieties, especially crucial in regions like Africa. Integrating CWRs into breeding programs can enhance food security amidst climate change [37]. Furthermore, there is a need to ensure equal distribution by implementing policies to prevent resource concentration and curb food waste. France’s regulations mandating supermarkets to donate unsold food have significantly reduced food waste, serving as a model for others [38]. Finally, there is a need to combat climate contributions by addressing the environmental impact of food systems, from deforestation to greenhouse gas emissions. Strategies like regenerative agriculture and reducing food waste can transform food systems into climate solutions [39].
By reinventing our food systems with innovative thinking, international cooperation, and a commitment to sustainability and equity, we can ensure food security, prevent ‘food wars’, and contribute positively to our global climate goals. Individuals, communities, and policymakers must prioritize resilient and equitable food systems, advocating for meaningful change at all levels [40]. The potential benefits of these changes are significant, as evidenced by the improved soil health and carbon sequestration of regenerative agriculture and the emissions reductions achievable through plant-based diets [41].
Preparing for population shifts
Climate change, beyond altering our physical environment, is poised to prompt substantial demographic changes, necessitating proactive preparation, and management. Understanding the global scale of this challenge is paramount. Climate displacement, as evidenced in low-lying Pacific Islands, mandates international cooperation and investment in mitigation and preventive measures [42]. Strengthening vulnerable regions through infrastructure resilience, economic diversification, and community empowerment is key to prevention.
Moreover, as our planet warms, disease patterns evolve, posing significant global health risks [43]. Diseases like malaria and dengue fever are spreading to new regions due to changing climate conditions, while disruptions to ecosystems increase the transmission of zoonotic diseases [43]. While not fully understood, climate change has led to changes in fungi, new fungal diseases, where they live, how they interact with humans, animals, and plants, and a disturbing increase in antifungal resistance and deaths [44]. Addressing these challenges demands climate-sensitive disease surveillance, robust public health systems, and interdisciplinary approaches to ecosystem management [45].
Anticipating inevitable displacement, adequate preparation for receiving regions is essential. This involves not only providing jobs and housing but also fostering social integration and preventing marginalization. Internationally, comprehensive agreements recognizing the rights of climate refugees are imperative, drawing from lessons learned during previous crises [46].
Effective planning for mass migrations requires predictive modeling to anticipate patterns and ensure that infrastructure and resources can accommodate newcomers. Ultimately, addressing this issue demands aggressive climate mitigation coupled with comprehensive planning to manage shifts effectively [47].
While the challenge of climate-induced population shifts is daunting, it is not insurmountable. Education, advocacy, and international collaboration are vital tools in addressing this issue. Let’s stand together to confront the realities of climate displacement, transforming it from a crisis into an opportunity for growth and renewal [48].
Upholding human rights
In the face of climate change, defending human rights becomes increasingly challenging and crucial. Upholding the principles of the Universal Declaration of Human Rights amidst such turmoil requires unwavering commitment, innovative solutions, and a fundamental reevaluation of justice in a climate-altered world [49,50]. Central to this effort is the establishment of social safety nets to ensure no individual or community faces the full impact of climate change without support. These systems should encompass universal basic income, robust healthcare services, and programs ensuring access to essentials like food and clean water, prioritizing equity and resilience [51].
Policy measures to combat climate change must be scrutinized to avoid unintended harm to vulnerable populations, as exemplified by the Dakota Access Pipeline dispute. This dispute involved the construction of an oil pipeline near the Standing Rock Sioux Reservation, raising concerns over water contamination and infringement on sacred lands, leading to widespread protests and legal battles [51]. Comprehensive social and environmental impact assessments are vital to prevent harm to marginalized communities disproportionately affected by environmental impacts [51]. The fight against climate change must prioritize climate justice, addressing the unequal distribution of climate impacts and working to rectify these disparities. This entails acknowledging historical emissions disparities and ensuring proportionate contributions to mitigation and adaptation efforts, particularly in supporting vulnerable populations [52].
An inclusive approach to policy-making is essential, involving communities most affected by climate change in decision-making processes to leverage their knowledge for sustainable living and adaptation strategies. This participatory approach ensures policies are grounded in the realities of those most impacted by climate change [53]. Transparency and accountability in governance are imperative for maintaining societal trust and stability amid climate change pressures. Strengthening democratic processes, judicial systems, and civil society ensures governments are held accountable for their actions or inactions on climate change [50].
Upholding human rights in a climate-altered future is both a daunting task and a moral imperative. It requires aligning responses to climate change with cherished values rather than undermining them. Everyone shares the responsibility of advocating for climate justice and supporting organizations working towards this goal [50]. Successful examples demonstrate the intersection between human rights and climate change. Legal actions like Urgenda Foundation vs. The Netherlands and the sustainable practices of indigenous communities highlight the potential for legal systems and traditional knowledge to uphold climate justice and mitigate climate change [54,55]. Recognizing and protecting these rights is critical for climate mitigation and adaptation efforts.
Investing in clean energy
The shift to clean energy is pivotal in mitigating the impacts of climate change and securing a sustainable future. Solar and wind energy, among other renewables, offer significant potential, with advancements in technology making them increasingly viable alternatives to fossil fuels [56,57]. Alongside harnessing new energy sources, upgrading energy infrastructure, such as transitioning to smart grids and investing in energy storage technologies, is essential for ensuring reliability and resilience [58].
Prioritizing energy efficiency in homes, businesses, and transportation further reduces overall energy demand, facilitating the transition to renewables [59]. However, this transition requires political commitment, with governments incentivizing renewable energy development through measures like tax credits and feed-in tariffs while phasing out fossil fuels. The clean energy sector presents opportunities for job creation, economic growth, and energy independence [59]. Individuals can contribute by adopting clean energy solutions and advocating for supportive policies.
Additionally, safeguarding marine ecosystems, and vital carbon sinks is crucial. Sustainable fishing practices, habitat protection, and marine-based renewables like wave and tidal power play key roles in preserving ocean health [60]. Progressive nations like Scotland demonstrate successful transitions to renewables, with renewable energy jobs projected to increase substantially by 2050 [57,61]. Innovations in battery technology further enhance renewable energy storage, enhancing reliability and efficiency [57].
Educating for a changing world
Education plays a crucial role in addressing climate change by fostering understanding, inspiring action, and equipping individuals with the necessary skills to navigate a warming world [62]. Climate literacy should be integrated across disciplines, encompassing not only the science but also the social, economic, and political dimensions of climate change [63].
Education should cultivate problem-solving, critical thinking, creativity, empathy, collaboration, and leadership skills essential for addressing the climate crisis. Experiential learning, such as field trips, can instill a deep appreciation for nature and motivate stewardship [62]. Access to quality climate education must be ensured for all, particularly marginalized communities disproportionately affected by climate change [64].
By empowering individuals with climate literacy, education can shape a sustainable, resilient, and equitable future. Efforts like the Committed to Climate and Energy Education (CLEAN) initiative and mandatory climate change lessons in schools in Italy demonstrate the importance of climate education [65]. Additionally, online platforms like Coursera and EdX offer free climate change courses, enhancing accessibility to education worldwide.
Financial and political support
The discourse surrounding climate change emphasizes the intricate interplay between finance, political decision-making, and climate action. Financial institutions hold considerable sway in steering climate mitigation and adaptation efforts, as their investment choices and risk assessments shape the flow of capital toward sustainable practices [66]. Regulatory frameworks and societal expectations influence investors’ decisions, underscoring the pivotal role of political stability and willingness to drive sustainable finance [67]. However, climate change also poses inherent risks to financial stability, including asset valuation fluctuations and supply chain disruptions, necessitating a reevaluation of risk assessment methodologies within financial institutions [68].
Additionally, governmental funding and policy support are crucial for scaling up climate initiatives, especially where private investment is lacking [69]. Public funding is essential for kick-starting and sustaining large-scale climate projects, while political leadership is necessary for enacting supportive policies and fostering international collaborations [70-72]. The synergy between financial support and political commitment is integral to the effective implementation of climate strategies, highlighting the need for a comprehensive approach to addressing climate change that integrates both financial and political dimensions.
