According to the UN Intergovernmental Panel on Climate Change (IPCC), more than three billion people live in areas “highly vulnerable” to climate change [PDF]. Many people are already experiencing some of the health impacts of climate change, and without immediate action, they will get worse.

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

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

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

Nearly a third of heat-related deaths are already caused by climate change, and the number of extreme weather events caused by climate change has quintupled in the past 50 years, killing more than 2 million people.

Climate Change And Health

Heat-related illnesses, such as heat stroke, heat exhaustion, and chronic kidney disease, are on the rise. While growing evidence shows us the dangers of extreme heat for maternal and neonatal health, mental health and chronic non-communicable diseases such as asthma and diabetes.

One billion people worldwide are at risk of heat stress if the Earth warms by 2 degrees Celsius. Professor Jean Palutikoff tells us about her research on interventions that can help.

The impact of these climate threats on health does not end here. From flooding or the spread of infectious diseases due to a warming climate, to disruptions to food systems due to extreme weather conditions, the impacts of climate change are felt everywhere and will affect the world’s most vulnerable populations.

In many parts of the world we are already seeing the effects of climate change on food systems and water supplies.

Rising temperatures threaten water security through increased evaporation, changes in rainfall patterns, and more snow falling as rain. It could also create difficult conditions for many types of crops and livestock, and yields of staple crops (a staple of the global diet) such as corn, rice, wheat and soybeans are likely to continue to decline due to rising prices. temperatures. ,

Sudden reductions in food production and access, along with reduced dietary diversity, have been linked to higher rates of malnutrition in many communities. And the warm climate also provides an ideal environment for the growth of food- and water-borne diseases.

If temperatures rise by more than 2°C, water availability for agriculture could decline by 20% after 2050 in areas that rely on glaciers and melting ice. In Asia alone, 800 million people depend on glaciers for fresh water.

As the world continues to warm, these phenomena will worsen, reversing years of progress to address food and water insecurity, which still affects the most disadvantaged populations around the world.

Introduction To Climate Change

The climate crisis is changing the Earth’s water. Read on to understand how it affects health around the world.

Climate change is a major factor in the emergence of diseases in new parts of the world. Changes associated with global warming can affect the survival, reproduction, abundance and distribution of pathogens, vectors and hosts.

Extreme weather events can create ideal conditions for the spread of infectious diseases such as cholera. And as global temperatures rise, diseases that were once limited to warm regions are also expanding their reach.

Many emerging infectious diseases are emerging in these tropical regions where warm temperatures are favorable for the life cycles of both pathogens and vectors. Vector-borne pathogens pose an increasing threat to human health. And now they are increasing.

For example, as the climate changes, mosquitoes and the diseases they carry (e.g., malaria, dengue, Zika) can spread and survive at higher latitudes and altitudes, while increased precipitation can also increase breeding sites. of vectors. Can help in construction. , This will increase the percentage of people who will come into contact with these deadly diseases in the world.

Read more about how global warming is allowing many diseases to expand their reach and put the health of millions of people at risk.

Climate change and higher temperatures are associated with an increase in allergens and harmful pollutants in the air we breathe. This can pose several health risks:

These air quality impacts will not occur uniformly around the world. For example, drought-prone areas are more likely to experience poor air quality due to smoke from wildfires or soil-borne dust, while cities may experience higher levels of air pollutants due to transportation and commercial burning.

Global Warming Effects: Effect Of Climate Change On Human Health

The effects of global warming will alter every aspect of society: from the food we eat to the cities we live in, to our jobs, our exercise and politics.

This is already happening. In 2022, 490 billion hours of potential work were lost due to heat, extreme flooding affected 33 million people in Pakistan and record heat caused almost 62,000 deaths in Europe.

It is difficult to measure the complex effects of these outcomes on physical and mental health, which are often associated with many other risk factors. However, as the world continues to warm, the risks of direct and indirect threats from sea level rise and climate change will become increasingly evident.

Jane Bratcher explains how flooding and climate change affected her daily life while growing up in the Philippines.

Human Health Impacts Of Climate Change

Many of these health problems are not new, but climate change exacerbates existing challenges and inequalities.

The people and places that are least able to adapt are those most at risk. Especially in low- and middle-income countries, where access to health care is already limited and the resources available to reduce or adapt to risks are also limited.

Cities will also be particularly vulnerable, as multiple threats such as extreme heat, air pollution and urban flooding combine and often compound damage. Nearly half of the world’s population lives in urban areas, but these health impacts will be most concentrated among economically and socially marginalized residents.

For example, a 2021 report found that Delhi is one of the world’s most vulnerable cities to climate change, with communities facing more severe heat waves, extreme rainfall and urban flooding, while air pollution is the leading cause of one in five deaths in India. .

Managing Climate Change Risks Is Imperative For Human Health

Cities are one of the biggest drivers of climate change. They can also be part of the solution.

We must shift from using fossil fuels to clean, renewable energy, stop deforestation and restore our natural habitats. The sooner we act to reduce the effects of climate change, the better off we will be in the future.

Even if we manage to reduce emissions and meet the global goal of zero emissions by 2050, many of the effects of global warming are now irreversible. These changes will continue to affect our climate in the future. Therefore, to protect the health of the population in the future, it is also necessary to adapt to current climate change.

Adaptation actions have increased in recent years, but progress has been uneven and slow. And today, most climate finance focuses on the essential task of reducing greenhouse gas emissions. Much greater political and financial support is needed to help populations around the world cope with the increasing impacts of climate change.

Global Health And Climate

Working in partnership with the most affected communities will support research and science-based solutions to address this urgent health challenge.

We fund critical research on the impacts of climate change on human health at national, regional and global levels around the world.

There are currently no open funding opportunities for climate and health. Learn more about the financing we offer. Climate change can no longer be seen simply as an environmental or ecological threat: the World Health Organization has declared climate change to be “the greatest health threat facing humanity.” As the climate continues to warm, the evidence overwhelmingly points to the fact that this changing climate will destroy the health of people living on this planet.

The long-awaited Lancet Countdown Report 2022 was published on October 26, 2022. In the title appears the phrase “Health at the mercy of fossil fuels”, strongly emphasizing that our dependence on fossil fuels will destroy us.

As countries face multiple crises simultaneously, their policies for COVID-19 recovery and energy sovereignty will have profound and potentially irreversible consequences for health and climate change. However, accelerated climate action would bring broader benefits, with more resilient health, food and energy systems and greater security and diplomatic autonomy, thus reducing the impact of health crises.
