It is generally accepted that climate change having a negative impact on food security. However, most of the literature variously focuses complex and many mechanisms linking stressors; links with production or productivity rather than security; future current effects. In contrast, we investigate extent to which changes in insecurity can be plausibly attributed change. We combine data for 83 countries from FAO experience scale (FIES) reanalysed ERA5-Land, use panel regression time-varying coefficients. This framework allows us estimate whether relationship between temperature anomaly changing over time. also control Human Development Index, drought measured by six-month Standardized Precipitation Index.

Global warming has been changing the planet's climate pattern, leading to increasing frequency, intensity and duration of extreme weather events natural disasters. These climate-changing affect various health outcomes adversely through complicated pathways. This paper reviews main signs change so far, e.g., suboptimal ambient temperature, sea-level rise other conditions, depicts interactive pathways between different such as wildfires, floods with a broad range outcomes. Meanwhile, modifying effect socioeconomic, demographic environmental factors on is summarised, that youth, elderly, females, poor those living in coastal regions are particularly susceptible change. Although Earth whole expected suffer from change, this review article discusses some potential benefits for certain regions, more liveable environment sufficient food supply. Finally, we summarise mitigation adaptation strategies against how these may benefit human ways. provides comprehensive concise introduction possible solutions, which map directions future research.

Summary

Background

The health impacts of climate warming are usually quantified based on daily average temperatures. However, extra risks might result from hot nights. We project the future mortality burden due to

Methods

selected night excess (HNE) represent intensity night-time heat, which was calculated as sum high temperature during time. collected historical data in 28 cities three east Asian countries, 1981 2010. associations between HNE and each city were firstly examined using a generalised additive model combination with distributed lag non-linear over 0–10 days. then pooled cumulative univariate meta-regression at national or regional levels. Historical hourly series projected under two scenarios greenhouse-gas emissions 1980–2099, ten general circulation models. attributable fraction scenario.

Findings

Our dataset comprised across countries (Japan, South Korea, China), including 9 185 598 deaths. time-series analyses showed significantly associated increased risks, relative risk days nights could be 50% higher than non-hot Compared rise mean (lower 20%), frequency would increase more 30% by 2100s. 3·68% (95% CI 1·20 6·17) strict emission control scenario (SSP126). Under medium (SSP245), up 5·79% (2·07 9·52), is 0·95% (−0·39 2·29) temperature.

Abstract Urban overheating, driven by global climate change and urban development, is a major contemporary challenge that substantially impacts livability sustainability. Overheating represents multifaceted threat to the well‐being, performance, health of individuals as well energy efficiency economy cities, it influenced complex interactions between building, city, scale climates. In recent decades, extensive discipline‐specific research has characterized heat assessed its implications on human life, including ongoing efforts bridge neighboring disciplines. The horizon now encompasses problems involving wide range disciplines, therefore comprehensive integrated assessments are needed address such interdisciplinarity. Here, our objective go beyond review existing literature instead provide broad overview defining holistic pathways for addressing life. We (a) detail characterization hazards exposure across different scales in various (b) identify individual sensitivities overheating increase vulnerability cause adverse populations, (c) elaborate adaptive capacities cities can adopt, (d) document energy, (e) discuss frontiers theoretical applied climatology, built environment design, governance toward reduction at scales. most critical challenges future application identified, targeting both gaps need greater integration assessments.

Increased extreme heat is among the clearest impacts of global warming, but economic effects waves are poorly understood. Using subnational data, metrics measuring temperature hottest several days in each year, and an ensemble climate models, we quantify effect intensity on growth globally. We find that human-caused increases have depressed output most poor tropical regions least culpable for warming.

As atmospheric greenhouse gas concentrations continue to rise, temperature and humidity will increase further, causing potentially dire increases in human heat stress. On physiological biophysical grounds, exposure higher levels of should worsen stress by decreasing sweat evaporation. However, population-scale epidemiological studies response often do not detect associations between high heat-related mortality or morbidity. These divergent, disciplinary views regarding the role health risks limit confidence selecting which interventions are effective reducing impacts projecting future risks.
