The Sixth Assessment Report (AR6) of the Intergovernmental Panel on Climatic Change (IPCC) found that, in light of rising global temperatures, adaptation will become more complex, and climatic risks will materialize faster than previously anticipated.

It also shows that 3.6 billion people live in regions incredibly vulnerable to climate change. The health effects are outstanding in low-income nations and small island developing states (SIDS), even if their relative contributions to global emissions are negligible. Compared to less sensitive areas, the death rate from extreme weather events during the past ten years was fifteen times higher in vulnerable regions.

The most vulnerable and disadvantaged groups, such as women, children, ethnic minorities, impoverished communities, migrants or displaced people, elderly populations, and those with underlying medical issues, are disproportionately affected by these climate-sensitive health concerns.

Summary

The health of people is fundamentally threatened by climate change. It impacts the physical environment and all facets of human and natural systems, such as the health systems’ operation and the social and economic backgrounds. As a result, it intensifies the threat and can undo decades of advancements in health. Storms, intense heat waves, floods, droughts, and wildfires are among the weather and climate events becoming more common and severe as climatic conditions change.

The risks of noncommunicable illnesses, infectious disease onset and transmission, mortality, and medical emergencies are all increased by these weather and climate-related hazards, which have an impact on health both directly and indirectly.

The infrastructure and workforce in the health sector are being impacted by climate change, which limits our ability to offer universal health coverage (UHC). More broadly, the environmental and social determinants of physical and mental health are weakened by climate shocks and increasing pressures such as shifting patterns of temperature and precipitation, droughts, floods, and rising sea levels.

Climate change affects all facets of health, including food systems, livelihoods, and access to clean air, water, and soil. Decades of progress in improving global health will be undermined, health risks will rise, and our shared commitment to guaranteeing everyone’s right to health will be broken if we continue to put off addressing climate change.

While the influence of climate change on human health is undeniable, it is still difficult to precisely quantify the scope and gravity of many dangers associated with climate change. However, as science progresses, we can more precisely identify the hazards and content of these health problems and link an increase in morbidity and mortality to global warming.

Seven hundred seventy million people experienced hunger in 2020, mainly in Asia and Africa. Food and nutrition problems are made worse by how climate change impacts the quantity, quality, and diversity of food available.

Variations in precipitation and temperature facilitate the transmission of diseases carried by vectors. The roughly 700,000 fatalities from these diseases that occur each year could increase if preventive measures are not taken.

Because of things like displacement and shattered social cohesion, climate change causes long-term difficulties in addition to acute mental health problems like anxiety and post-traumatic stress disorder.

According to recent studies, human-induced climate change is to blame for 37% of heat-related deaths. In the past 20 years, mortality from heat-related causes among seniors has increased by 70%. Compared to the average of 1981–2010, 98 million more people faced food insecurity in 2020.

By the 2030s, the WHO estimates that the effects of climate change on diseases like malaria and coastal floods will result in an additional 250,000 fatalities annually. However, modeling still has issues, mainly when accurately representing hazards like migratory pressures and drought.

The threat posed by the climate catastrophe is to reverse the last half-century of gains in development, global health, and poverty alleviation, as well as to exacerbate already-existing health disparities between and within people.

It seriously jeopardizes the realization of universal health coverage in several ways, such as by increasing the burden of disease already present and making it more difficult to obtain health treatments, frequently just when those services are most needed. Approximately 12% of the global population, or over 930 million people, spend at least 10% of their family income on medical expenses

Around 100 million people fall into poverty each year as a result of health shocks and strains, with the majority of the world’s poorest people lacking health insurance. The effects of climate change exacerbate this tendency.

Changes in climate and equity

The susceptibility of populations, their resistance to the current rate of climate change, and the speed and scope of adaptation will be the primary determinants of the short- to medium-term health implications of climate change. Longer-term consequences will progressively rely on how much revolutionary action is done to cut emissions and prevent exceeding hazardous temperature thresholds and maybe irreversible tipping points.

Although no one is safe from these risks, those living in low-income and underprivileged nations and communities are the ones whose health is being negatively impacted by the climate crisis the most, even though they also make a minuscule contribution to its causes.

The need for equality is highlighted by addressing the health effects of climate change. This means that the costs of adaptation and mitigation should fall disproportionately on those most accountable for emissions, prioritizing vulnerable groups and promoting health equity.

Need for quick response.

To avert catastrophic health repercussions and millions of fatalities linked to climate change, global warming must be limited to 1.5°C. A certain amount of global temperature rise has already been brought about by past emissions, making more climate change unavoidable. Even a 1.5°C increase in global warming is deemed unsafe, as every tenth of a degree, more warming will have a detrimental effect on people’s lives and health.

WHO reaction

The three primary goals of WHO’s reaction to these difficulties are as follows:

Encourage implementing policies that prioritize health in the context of mitigating climate change, expedite mitigation efforts that yield the most tremendous health benefits, support a quick and equitable transition to a clean energy economy, and harness the power of the health community to influence public opinion and policy change.

Provide core services, environmental sustainability, and climate resilience as essential elements of universal health coverage (UHC) and primary health care (PHC); assist health systems in transitioning from high-emitting, carbon-intensive health systems to more affordable, dependable, and environmentally sustainable ones; and mainstream climate resilience and environmental sustainability into health service investments, including the training of the medical workforce.

Protect health from the many effects of climate change by evaluating health vulnerabilities, creating health plans, integrating climate risk and putting in place surveillance and response systems for key risks like infectious diseases and extreme heat, encouraging resilience and adaptation in industries that have a direct impact on health, like food and water, and closing the funding gap for these measures. 

Leadership and Awareness-Building:

 To concentrate health in climate policy, particularly those enacted through the UNFCCC, WHO takes the lead in highlighting the health effects of climate change. WHO works to integrate climate change into health objectives like UHC and aims to achieve carbon neutrality by 2030 by collaborating with significant health agencies, medical professionals, and civil society.

Evidence and Monitoring: 

The World Health Organization (WHO) collaborates on global evidence summaries, supports countries in their evaluations, and tracks advancements through its network of specialists worldwide. Deploying efficient policies and improving knowledge and data availability are the main priorities.
