Impact Of Climate Change On Human Health Pdf – Climate change is the greatest health threat facing humanity, and health professionals worldwide are already responding to the health harms caused by this unfolding crisis.
The Intergovernmental Panel on Climate Change (IPCC) has concluded that to avoid catastrophic health effects and prevent millions of deaths related to climate change, the world must reduce the temperature to 1.5°C. Past emissions have made a level of global warming and other changes to the climate impossible. Global warming of even 1.5°C would not be considered safe, however; Every additional tenth of a degree of warming will have a significant impact on human life and health.

While no one is safe from these risks, the people whose health is harmed first and worst by the climate crisis are the people who contribute the least to its causes, and are least able to protect themselves and their families against it – low-income people. and less privileged countries and regions.

The climate crisis threatens to undo the last fifty years of progress in development, global health, and poverty reduction, and to further widen the health inequalities that exist between and among populations. It seriously harms the realization of universal health coverage (UHC) in various ways – including by compounding the existing burden of disease and by increasing existing barriers to accessing health services, often at times when they most needed Over 930 million people – around 12% of the world’s population – spend less than 10% of their household budget to pay for health care. With the poorest people uninsured, health emergencies and stressors currently push 100 million people into poverty every year, with the effects of climate change exacerbating this trend.
Climate change is already affecting health in many ways, including leading to death and illness from increasingly frequent weather events, such as heat waves, storms and floods, disruption of systems food, increase in zoonoses and food-, water- and vector-borne diseases, and mental health issues. Furthermore, climate change threatens many social determinants of good health, such as livelihoods, equality 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, migrants or oppressed people. displacement, the elderly population, and those with underlying health conditions.
Overview of climate-sensitive health hazards, 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 indisputable that climate change will affect human health, it remains challenging to accurately estimate the magnitude and impact of many climate-related health risks. However, scientific advances in progress allow us to attribute the increase in morbidity and mortality to human warming, and more accurately determine the risks and extent of these health threats.
The Connections Between Population And Climate Change
In the short- to medium-term, the health effects of climate change will be determined primarily by the vulnerability of populations, their sensitivity to the current rate of climate change and the extent and speed of adaptation. In the long term, the effects will depend on the amount of change action taken now to reduce emissions and avoid the violation of dangerous temperature limits and irreversible emission points. (CO2) and other by-products from fossil fuels, not only cause climate change but also pollute the atmosphere, causing many public health problems.
The National Climate Assessment claims that climate change will affect air quality through outdoor and indoor air pollution, as well as allergens.
Climate change and rising temperatures increase the formation of O3 as well as other substances. These contribute to the growth in smog across cities in the U.S. O3 is associated with reduced lung function, increased hospital admissions and emergency room visits for asthma and increased premature deaths. Studies show that increased O3 could lead to thousands of additional illnesses and deaths per year over the next decade.
Also, increasing CO2 levels increase the number of plants that release allergens. Therefore, for people with existing allergic conditions there may be an increased health risk from climate change. Simultaneous exposure to allergens and air pollutants can increase the severity of allergic reactions for some people.

Climate change is also increasing the intensity and frequency of wildfires, and the effects of wildfires on human health are well documented. Substances and toxins, including carbon monoxide, nitrogen oxides, and other compounds from wildfires, worsen local air quality for days or even months during and after a fire. It is estimated that there were between 260,000 and 600,000 deaths worldwide from secondhand smoke between 1997-2006, annually.
Poor air quality can affect public health in many ways. Increased production of O3, frequent and large fires that significantly reduce air quality, as well as longer exposure time to allergens are all associated with many health problems.

Road map (see Guide to Report). Moving from left to right along a health impact pathway, the three middle columns show how climate drivers influence an individual’s or community’s exposure to a health threat and the resulting change in health outcome. The overall climate effect is summarized in the last gray sheet. For more insight into how climate change affects health, and to see the environmental, structural, social, and behavioral factors that interact in determining health outcomes, see the pathway diagrams presented in Chapter 2 -8.
Climate change is a major threat to the health of the American people. The effects of human-made climate change are increasing across the country. Greenhouse gas concentrations result in increases in temperature, changes in precipitation, increases in the frequency and intensity of some extreme weather events, and rising sea levels. These climate change impacts threaten our health by affecting our food and water resources, the air we breathe, the weather we experience, and our interactions with the built and natural environments. As the climate continues to change, the risks to human health continue to grow.
Current and future climate impacts expose more people in more places to public health threats. Already in the United States, we have noticed climate-related increases in our exposure to high temperatures; frequent, severe, or chronic
; degraded air quality; diseases spread by food, water, and insects (such as ticks and mosquitoes); and stressors to our mental health and well-being. Almost all of these threats are expected to worsen with continued climate change. Some of these health threats will occur over longer periods of time, or at unpredictable times of the year; some people will be exposed to threats they have never experienced before in their situations. Overall, the incidence of beneficial health effects of climate change is limited in number and applies to specific regions or populations. For example, the decrease in cold-related deaths is projected to be less than the increase in heat-related deaths in most regions.

Trigger. Through the combined effect of these factors, climate change exacerbates some existing health threats and creates public health challenges. While all Americans are at risk, some populations are disproportionately vulnerable, including low-income, some communities of color, immigrant groups (including those with limited English proficiency), the indigenous people, children and pregnant women, the elderly, vulnerable working groups, people with disabilities, and people with existing or
In recent years, scientific understanding of how climate change increases risks to human health has improved significantly. Even so, the ability to assess, monitor, and project health impacts varies across climate impacts. For example, information on health outcomes varies in terms of whether there are complete, long-term data sets that allow the extent of observed changes, and whether existing models can project effects in times and areas of interest. There are also differences in the metrics available for detecting or detecting different health effects. For some health effects, available metrics only describe changes in exposure risk, while for others, metrics describe changes in actual health outcomes (such as the number of new cases of disease or an increase in deaths ).
This study deepens and expands our understanding of climate-related health impacts by providing a more detailed description of climate-related health burdens in the United States. It is based on the 2014 National Climate Assessment
