Impact Caused By Climate Change On Human Health – Climate change is affecting people’s health globally both directly through increased exposure to extreme weather and indirectly through impacts on the physical, natural, and social systems on which health depends (1). Climate change is also exacerbating existing threats to food and water security, built infrastructure, essential services and livelihoods.

Climate change has many impacts on human health. Some of the major health risks caused by climate change include:

Heatwaves: Climate change is increasing average global temperatures as well as the frequency, intensity, and duration of heatwaves (2). Exposure to extreme heat can cause acute kidney damage, heat stroke (3), adverse pregnancy outcomes (4) (5), disrupted sleep patterns (6), adverse effects on mental health, existing cardiovascular and respiratory is associated with disease progression and exacerbations. Non-accident and injury-related mortality (7). Elderly people, pregnant women, newborns, socially isolated people and people who work outdoors are more vulnerable (8) (9).

The Missing Risks Of Climate Change

Infectious disease transmission: Climate change is affecting the spread and transmission of many infectious diseases, including vector-borne, food-borne and water-borne diseases. Adaptability for transmission of many infectious diseases is affected by changes in temperature and precipitation. As temperatures warm, the range of disease-carrying insects, such as mosquitoes and ticks, is increasing. It increases the risk of diseases like malaria, dengue, Lyme disease, and others. Changes in rainfall patterns and increased frequency of floods can lead to contamination of water sources, resulting in the spread of waterborne diseases such as cholera and typhoid.

Mental health: Climate change is affecting mental health, psychological well-being and their social and environmental determinants (1). Globally, mental health problems are on the rise. Over the past decade, mental health conditions and substance use disorders have increased by 13%, largely due to demographic changes (as of 2017). Mental health problems now account for 1 in every 5 years of disability. According to the World Health Organization, suicide is the second leading cause of death among people aged 15-29, affecting approximately 20% of the world’s children and adolescents.

Food Security and Malnutrition: Compared to 1981-2010, increased temperatures in 2021 shortened crop growing seasons. Globally 9·3 days for maize, 1·7 days for rice, and 6·0 days for winter and spring wheat, and 98 million more reported moderate to severe food insecurity in summer 2020 (1). were associated with people.

Quantitative Methods For Climate Change And Mental Health Research: Current Trends And Future Directions

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

Whether it’s an increase in water-borne diseases during floods in South Sudan, high temperatures leading to premature births in Australia or the bread crisis faced by families after another year of conflict and failed crops in Syria – almost every season’s story. There is also a health story.

More than four in ten people live in areas “highly vulnerable” to climate change, according to a recent report by the United Nations’ Intergovernmental Panel on Climate Change (IPCC). Many people are already experiencing some of the health impacts of climate change, and these are set to get much worse without immediate action.

Global warming is a long-term increase in the average global surface temperature due to rising 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.

How To Protect Planetary And Human Health

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 it climate change.

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

One-third of heat-related deaths are already attributable to climate change, and the number of climate change-driven extreme weather disasters 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. While growing evidence is showing us the risks of extreme heat to maternal and newborn health, mental health and chronic non-communicable diseases such as asthma and diabetes.

Learning To Treat The Climate Emergency Together: Social Tipping Interventions By The Health Community

A billion people worldwide could face heat stress if the Earth’s temperature rises by 2 degrees Celsius. Professor Jean Plutikoff tells us about her research into interventions that can help.

The impact of these seasonal hazards on health does not end here. From the spread of infectious diseases caused by floods or hot weather, to the disruption of food systems by extreme weather, the knock-on effects of climate change are felt everywhere and will hit the world’s most vulnerable populations hardest. .

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 by increasing evaporation, changing precipitation patterns, and causing snow to fall faster as rain. This could create difficult conditions for many types of crops and livestock farming, with the production of staple crops such as corn, rice, wheat and soybeans (which are the mainstay of the world’s diet) downgraded by warmer temperatures. The trend continues. .

Human Health Impacts Of Ecosystem Alteration

The sudden loss of food production and access to food, coupled with a reduction in dietary diversity, has been linked to increased rates of malnutrition in many communities. And warm weather provides an ideal environment for food and waterborne diseases to thrive.

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

These events will worsen as the world continues to warm, reversing years of progress in addressing food and water insecurity that still affects the most underserved populations worldwide.

The climate crisis is changing the water on Earth. Read on to understand how its health effects are felt around the world.

How Much Would It Cost To End Climate Change? Get The Facts

Climate change is a major factor in the emergence of diseases in new parts of the world. The survival, reproduction, abundance, and distribution of organisms, vectors, and hosts may be affected by changes associated with global warming.

Extreme weather events can result in ideal conditions for the spread of infectious diseases, such as cholera. And as global temperatures rise, diseases that were once confined to warmer regions are also expanding their range.

Many newly emerging infectious diseases originate in these tropical regions where warm temperatures are favorable to the life cycle of both pathogen and vector. Vector-borne pathogens pose an increasing threat to human health. And now they are on the rise.

For example, as climate changes, mosquitoes, and the diseases they transmit (eg malaria, dengue, Zika) may spread and survive at higher latitudes and altitudes, while increased rainfall increases breeding sites for vectors. Can support creation. . This will increase the proportion of the world exposed to these deadly diseases.

Climate change and higher temperatures are linked to an increase in allergens and harmful pollutants in the air we breathe. It can present several health risks:

These impacts on air quality will not be uniform across the globe. For example, areas susceptible to drought are more likely to experience poor air quality from wildfire smoke or dust blown from soil, while cities may experience higher levels of air pollutants from traffic and commercial combustion. .

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

It is already happening. In 2020, 295 billion potential work hours were lost due to extreme heat exposure and at least 7 million people were internally displaced by environmental disasters.

The complex physical and mental health effects of these outcomes are difficult to measure, often associated with myriad other risk factors. However, as the world continues to warm the threats from rising sea levels and the direct and indirect threats posed by climate change and climate change will become increasingly apparent.
