Impact Of Regional Climate Change On Human Health – Climate change presents a fundamental threat to human health. It affects the physical environment as well as all aspects of both natural and human systems – including social and economic conditions and the functioning of health systems. It is therefore a threat multiplier, undermining and potentially reversing decades of health progress. As climate conditions change, more frequent and intense weather and climate events are observed, including storms, extreme heat, floods, droughts and wildfires. These weather and climate hazards directly and indirectly affect health, increasing the risk of mortality, non-communicable diseases, the emergence and spread of communicable diseases and health emergencies.

Climate change is also affecting our health workforce and infrastructure, reducing our ability to provide universal health coverage (UHC). More fundamentally, climate shocks and increasing stressors such as changing temperature and precipitation patterns, droughts, floods and sea level rise undermine environmental and social determinants of physical and mental health. All aspects of health are affected by climate change, from clean air, water and soil to food systems and livelihoods. Further delay in addressing climate change will increase health risks, undermine decades of progress in global health, and violate our collective commitment to guarantee the human right to health for all.

It also reveals that 3.6 billion people already live in areas highly sensitive to climate change. Despite contributing the least to global emissions, low-income countries and small island developing states (SIDS) suffer the most severe health impacts. In vulnerable areas, death rates due to extreme weather over the past decade were 15 times higher than in less vulnerable areas.

Climate change is impacting health in myriad ways, including increased frequency of extreme weather events such as heat waves, storms and floods, disruption of food systems, zoonoses and food-, water- and vector-borne diseases leading to death and illness. -Communicable diseases, and mental health problems. Furthermore, climate change is undermining many social determinants of good health, such as livelihoods, equity and access to health care and social support structures. These climate-sensitive health risks are disproportionately felt by the most vulnerable and disadvantaged, including women, children, ethnic minorities, poor communities, migrant or displaced persons, older populations and those with underlying health conditions.

Figure: An overview of climate-sensitive health risks, their manifestation pathways and vulnerability factors. Climate change affects health directly and indirectly and is strongly mediated by environmental, social and public health determinants.

Although it is unequivocal that climate change affects human health, it remains challenging to accurately estimate the magnitude and impact of many climate-sensitive health risks. However, scientific progress is gradually allowing us to attribute global warming to increased morbidity and mortality and to more accurately quantify the risks and magnitudes of these health threats.

Chapter 3 — Global Warming Of 1.5 ºc

Data indicate that 2 billion people lack safe drinking water and 600 million suffer from foodborne illness annually, with children under 5 years of age accounting for 30% of foodborne deaths. Climate stress increases the risk of waterborne and foodborne diseases. In 2020, 770 million face hunger, mainly in Africa and Asia. Climate change affects the availability, quality and diversity of food, exacerbating food and nutrition crises.

Changes in temperature and precipitation increase the spread of vector-borne diseases. Without preventive measures, deaths from such diseases, currently more than 700 000 annually, may increase. Climate change induces both immediate mental health problems, such as anxiety and post-traumatic stress, and long-term disorders due to factors such as displacement and social cohesion.

Recent studies attribute 37% of heat-related deaths to human-induced climate change. Heat-related deaths among those over 65 increased by 70% in two decades. In 2020, 98 million more experienced food insecurity than the 1981-2010 average. Climate change impacts on diseases such as malaria and coastal flooding conservatively project 250,000 additional annual deaths by 2030. However, modeling challenges remain, particularly around capturing risks such as drought and migration pressures.

Impact Of Regional Climate Change On Human Health

The climate crisis threatens to undo the last 50 years of progress in development, global health and poverty reduction, and widens existing health inequalities within and between populations. This seriously jeopardizes the realization of UHC in several ways, including by increasing the existing burden of disease and exacerbating existing barriers to accessing health services, often when they are most needed. More than 930 million people – about 12% of the world’s population – spend at least 10% of their household budget on health care. The poorest people are largely uninsured, with health shocks and stresses already pushing nearly 100 million people into poverty each year, with the effects of climate change exacerbating this trend.

Health Impacts Of Climate Change And Ozone Depletion: An Ecoepidemiologic Modeling Approach.

In the short to medium term, the health impacts of climate change will largely be determined by the vulnerability of populations, their resilience to current rates of climate change, and the extent and speed of adaptation. In the long term, impacts will increasingly depend on how transformative steps are taken now to reduce emissions and avoid breaches of dangerous temperature thresholds and potentially irreversible tipping points.

While no one is safe from these risks, the climate crisis is affecting human health first and worst among the people who contribute least to its causes and are least able to protect themselves and their families against it: low-income people and disadvantaged countries and communities.

Addressing the health burden of climate change underscores the equity imperative: those most responsible for emissions should bear the highest mitigation and adaptation costs, emphasizing health equity and vulnerable group priorities.

To avoid catastrophic health effects and prevent millions of deaths from climate change, the world must limit temperature rise to 1.5°C. Past emissions have already made a certain level of global temperature rise and other climate changes inevitable. Even 1.5 degrees Celsius of global warming is not considered safe; Every additional tenth of a cent of warming will have a severe impact on human life and health.

Regional Impacts And Consequences Across All Action Fields Of Climate…

Leadership and awareness raising: Emphasizing the health impacts of climate change, leading to the goal of centralizing health in climate policies, including the UNFCCC. Major health organizations, in partnership with health professionals and civil society, seek to embed climate change in health priorities such as UHC and the goal of carbon neutrality by 2030.

Evidence and Monitoring: , with a global network of experts, contributes to global evidence summaries, supports countries in their assessments and monitors progress. Emphasis is placed on establishing effective policies and increasing access to knowledge and data.

Capacity Building and Country Support: Support is provided to the Ministry of Health through the Office, focusing on cross-sector collaboration, updated guidance, hands-on training, and support for project preparation and implementation, as well as securing climate and health funding.

Impact Of Regional Climate Change On Human Health

In the past few years, we have seen that rising temperatures and extreme weather events can significantly affect human health around the world.

Managing Climate Change Risks Is Imperative For Human Health

Whether it’s a spike in water-borne diseases during floods in South Sudan, premature births due to high temperatures in Australia, or the bread crisis facing families in Syria after another year of conflict and crop failure – nearly every climate story is also a health story.

More than four in ten people live in areas “highly vulnerable” to climate change, according to the latest report by the UN’s Intergovernmental Panel on Climate Change (IPCC). Many are already experiencing some of the health effects of climate change, and these are only going to get worse without urgent action.

Global warming is a long-term increase in average global surface temperature due to increased levels of greenhouse gases in the atmosphere. Emissions from the fossil fuels we burn (such as coal and oil) are the main cause of dangerous increases in greenhouse gases.

This warming in turn warms the oceans and changes the timing, geography and intensity of weather and climate events, as well as sea level rise. This is what we call climate change.

Extreme climate and weather events, such as droughts, floods and heat waves, are increasing in intensity and frequency around the world.

Almost a third of heat-related deaths are already attributable to climate change, and the number of extreme weather disasters driven by climate change has increased fivefold over the past 50 years, killing more than 2 million people.

Heat-related illnesses such as heat stroke, heat exhaustion and chronic kidney disease are on the rise. However, growing evidence is showing the risks of extreme heat to our maternal and newborn health, mental health and chronic non-communicable diseases such as asthma and diabetes.
