How Does Climate Change Affect Human Health – Climate change is a fundamental threat to human health. It affects the physical environment as well as all aspects of natural and human systems – including social and economic conditions and the functioning of health systems. It is therefore a risk multiplier, debilitating and potentially reversing decades of health progress. As climate conditions change, weather and climate events will become more frequent and intense, including hurricanes, extreme heat, floods, droughts and wildfires. These weather and climate hazards directly and indirectly affect health, risk of mortality, non-communicable diseases, the emergence and spread of communicable diseases and health crises.

Climate change also affects our health workforce and infrastructure by reducing our ability to provide universal health coverage (UHC). Fundamentally, climate shocks and increasing stressors such as temperature change and precipitation, droughts, floods and sea-level rise degrade the environmental and social determinants of physical and mental health. Climate change affects all aspects of health, from clean air, water and soil to food systems and livelihoods. Further delays in addressing climate change will increase health risks, reverse decades of progress in global health, and undermine our collective commitment to guaranteeing the human right to health for all.

The Intergovernmental Panel on Climate Change’s (IPCC) Sixth Assessment Report (AR6) concluded that climate risks are developing rapidly and will become more intense sooner than expected, and with global warming Compliance will be more difficult.

A Human Disease Indicator For The Effects Of Recent Global Climate Change

It further reveals that 3.6 billion people already live in areas that are highly vulnerable to climate change. Despite contributing little to global emissions, low-income countries and small island developing States (SIDS) have the greatest health impacts. In vulnerable areas, deaths from extreme weather events over the past decade were 15 times higher than in less vulnerable areas.

Climate change affects health in many ways, including deaths and illnesses from extreme weather events such as heat waves, hurricanes and floods, disruption of food systems, increases in zoonotic diseases, and food-, water- and vector-borne transmission. Illness and mental health problems. In addition, climate change undermines 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 vulnerable, including women, children, ethnic minorities, poor communities, migrants or displaced people, older populations and people with underlying health conditions. .

Figure: Overview of climate-sensitive health risks, their exposure 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 not clear how climate change affects human health, accurately estimating climate-sensitive health risks and the impact of these risks is challenging. However, scientific advances are increasingly enabling us to accurately measure the magnitude of morbidity and mortality from global warming and the risks and magnitudes of these health risks.

World Health Day 2022: How Does Climate Change Affect Our Health?

Figures show that 2 billion people lack access to safe drinking water and 600 million people die each year from food-borne diseases, with children under 5 accounting for 30% of all food-related deaths. Climate stress increases the risk of water and foodborne diseases. In 2020, 770 million people were facing hunger, most of them in Africa and Asia. Climate change affects the availability, quality and diversity of food, thereby exacerbating food and nutrition crises.

Changes in temperature and precipitation increase the spread of vector-borne diseases. Without preventive measures, deaths from such diseases, which currently exceed 700,000 each year, will increase. Climate change creates immediate mental health problems, such as anxiety and post-traumatic stress, and long-term disorders such as displacement and disruption of social integration.

Recent research has attributed 37% of heat-related deaths to human-caused climate change. Heat-related deaths among people over the age of 65 have increased by 70% in two decades. In 2020, 98 million more experienced food insecurity than the 1981-2010 average. Conservative estimates predict an additional 250,000 deaths by 2030 due to the effects of climate change from diseases such as malaria and coastal flooding. However, modeling challenges remain, especially dealing with hazards such as drought and migration stress.

The climate crisis threatens to undo the progress of the past 50 years in development, global health and poverty reduction, and exacerbate existing health inequalities within and between populations. This seriously threatens the achievement of UHC in a variety of ways, including increasing the existing burden of disease and increasing existing barriers to access to 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. With the poor largely uninsured, health shocks and stressors push nearly 100 million people into poverty each year, a trend exacerbated by the effects of climate change.

Keeping Food Safe In An Era Of Climate Change

In the short and medium term, the health impacts of climate change will be determined primarily by people’s vulnerability, ability to cope with the current rate of climate change, and its speed and pace. In the long term, outcomes will increasingly depend on the extent to which transformative action is taken now to reduce emissions and avoid dangerous temperature thresholds and irreversible tipping points.

While no one is immune to these risks, the people whose health will suffer first and most from the climate crisis are those who contribute least to these causes and are least likely to suffer from them. Able to protect themselves and their families from: low-income and poor people countries and communities.

Addressing the health burden of climate change highlights the imperative importance of equity: those most responsible for emissions should bear the greatest mitigation and adaptation costs, emphasizing health equity and prioritizing vulnerable groups. .

To avoid dire health consequences and millions of deaths due to climate change, the world must limit temperature increase to 1.5 degrees. Past emissions have already caused a certain level of global warming and further climate change is inevitable. However, even a global warming of 1.5 degrees Celsius is not considered safe. Any additional heating decisions will seriously affect people’s lives and health.

Building leadership and awareness: Leaders emphasize the consequences of climate change for health, with the goal of centralizing health in climate policies through the UNFCCC. Working in partnership with leading health institutions, health professionals and civil society, it strives to incorporate climate change into health priorities such as UHC and targeting carbon neutrality by 2030.

Evidence and Monitoring: With an international network of experts, Global provides evidence summaries, supports countries in their assessments and monitors progress. Emphasis is placed on using effective strategies and improving access to information and data.

Capacity Building and Country Support: Through the Offices, support is provided to Ministries of Health, on cross-sectoral collaboration, updated guidelines, practical training and support for project preparation and implementation as well as on securing climate and health funding. focuses on Leads the Alliance for Change on Climate and Health (ATTACH), which brings together a range of health and development partners to support countries in meeting their commitments to climate-resilient low-carbon health systems.

In 2015, a farm worker died in a 109-degree heatstroke in a California citrus grove. In Missouri, hospitalizations for heat-related illnesses increased in 2006, a year with unusually high temperatures.

And since the arrival of Asian tiger mosquitoes in Memphis in 1983, the insects — which can spread the Zika, dengue and West Nile viruses — have invaded 37 states. In the densely populated northeast, the Asian tiger population is poised to triple its range by 2045 – the disease’s toll will rise from 18 million to more than 30 million.

But we are not helpless against such threats, according to a recent report co-authored by Stanford University researchers. A few weeks before the 2016 election, the authors presented a report to two presidential transition teams. The report, titled “Health: The Human Face of Climate Change, Perspectives and Recommendations for the Next President of the United States,” recommends that the next administration launch a formal, decade-long emergency response to climate change that includes the U.S. Administered by the State Department, the global health security issue frames climate change—in other words, as a serious public health threat to people around the world.

The report, “The Human Faces of Climate Change,” was one of a series of 14 climate reports presented at the 2016 Stanford conference titled “Setting the Climate Agenda for the Next President of the United States.”
