Climate change, a global phenomenon characterized by alterations in weather patterns, rising global temperatures, and an increase in extreme weather events, poses a significant challenge to sustainable development and directly impacts the United Nations' Sustainable Development Goals (SDGs). The SDGs, a collection of 17 interlinked global goals designed as a "blueprint to achieve a better and more sustainable future for all" by 2030, are intrinsically connected to climate action.
Central to this relationship is SDG 13: Climate Action, which calls for urgent measures to combat climate change and its impacts. This goal acknowledges that without immediate and sustained action to reduce greenhouse gas emissions, the achievement of other SDGs is at risk. Climate change exacerbates existing challenges such as poverty (SDG 1), hunger (SDG 2), and health issues (SDG 3) by disrupting livelihoods, food security, and health conditions. For instance, increased temperatures and changing precipitation patterns affect crop yields, leading to food insecurity. Similarly, the spread of diseases is influenced by climatic conditions, directly impacting public health.
Furthermore, climate change has a disproportionate impact on vulnerable populations, including those living in poverty, exacerbating inequalities (SDG 10). It affects access to clean water (SDG 6) and sanitation, with changing weather patterns disrupting water supply. The degradation of natural habitats and ecosystems under climate stress threatens life below water (SDG 14) and life on land (SDG 15), leading to biodiversity loss and affecting the livelihoods of those dependent on these ecosystems.
The economic impacts of climate change are also profound, affecting sustainable industrialization (SDG 9) and undermining economic growth (SDG 8). Severe weather events cause extensive damage to infrastructure and lead to economic losses, while changes in climatic conditions can impact industries such as agriculture, fishing, and tourism.
Moreover, climate change poses challenges to achieving sustainable cities and communities (SDG 11) as urban areas face increased risks of flooding, heatwaves, and air pollution. This necessitates the development of resilient infrastructure and adaptive urban planning. Additionally, the energy sector, integral to most economic activities, must transition towards clean and renewable sources (SDG 7) to mitigate climate change, highlighting the interdependence of the SDGs.
Global partnerships (SDG 17) are crucial in addressing climate change, as it is a global issue requiring international cooperation and funding. Developed countries are urged to support developing nations in climate mitigation and adaptation efforts, recognizing the shared responsibility and differing capacities among nations.
The COVID-19 pandemic and climate change are complex existential threats, unpredictable in many ways and unprecedented in modern times. There are parallels between the scale and scope of their impacts and responses. Understanding shared drivers, coupled vulnerabilities, and criteria for effective responses will help societies worldwide prepare for the simultaneous threats of climate change and future pandemics. We summarize some shared characteristics of COVID-19 and climate change impacts and interventions and discuss key policy implications and recommendations.
The ability to maintain a (relatively) stable body temperature in a wide range of thermal environments by use of endogenous heat production is a unique feature of endotherms such as birds. Endothermy is acquired and regulated via various endocrine and molecular pathways, and ultimately allows wide aerial, aquatic, and terrestrial distribution in variable environments. However, due to our changing climate, birds are faced with potential new challenges for thermoregulation, such as more frequent extreme weather events, lower predictability of climate, and increasing mean temperature.
Climate change is the most critical public health crisis of the 21st century. Physical and medical sequelae of climate and weather-related events are well documented and may be addressed in clinical practice. Mental health impacts of climate change are increasingly addressed in the literature but remain underrecognized by clinicians. This report focuses on mental health impacts of climate change through the theoretical framework of Maslow's Hierarchy of Needs.
Climate change is reshaping the comparative advantage of regions and hence driving migration flows, principally toward urban areas. Migration has multiple benefits and costs in both origin and destination regions. Coordinated policies that recognize how and why people move can reduce future costs and facilitate adaptation to climate change both within borders and internationally.
Global climate change and land degradation are two grand changes facing humanity. In this perspective, we examine how degraded and abandoned farmland can be harnessed to fight climate change. Building upon and extending natural climate solutions, we suggest that the carbon capture and storage of abandoned farmland can be accelerated and maximized through restoring the diversity of plant species, applying biochar to soil, and co-developing renewable energy such as solar power. The benefits of these approaches extend far beyond climate-change mitigation and land restoration.
Although several empirical studies and systematic reviews have documented the mental health impacts of global climate change, the range of impacts has not been well understood. This review examines mental health impacts of three types of climate-related events: (1) acute events such as hurricanes, floods, and wildfires; (2) subacute or long-term changes such as drought and heat stress; and (3) the existential threat of long-lasting changes, including higher temperatures, rising sea levels and a permanently altered and potentially uninhabitable physical environment.
Climate change will expose mammals to an array of stressors, some new, and some with increased frequency and severity. Those stressors influence endocrine and metabolic function, with potential consequences for the survival and persistence of mammalian species. Here, we review the similar consequences of climate change on the physiological function of terrestrial mammals, including direct effects of increasing air temperatures and reduced water availability, as well as the indirect effect of reduced or unpredictable food supply.
