Either the increase in water-borne diseases during the floods in South Sudan, and the hot weather causing premature births in Australia, or the bread crisis facing families in Syria after a year of conflict and poor harvests – almost every weather story is also a health story. .

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

Global warming is a long-term increase in the average global temperature caused by increased levels of greenhouse gases in the atmosphere. The emissions we burn (such as coal and oil) are the main cause of the increase in greenhouse gases.

This warming also warms the oceans and causes changes in weather, climate and extreme weather and events, including rising sea levels. We call this climate change.

Extreme weather events, such as droughts, floods and heat waves, are becoming more severe and frequent around the world.

Of Human Infectious Diseases Can Be Worsened By Climate Change

About three-thirds of heat-related deaths are already linked to climate change, and the number of climate-related disasters has increased five-fold in the past 50 years, which killing more than two million people.

Heat-related illnesses such as stroke, heat exhaustion and kidney disease continue to increase. Growing evidence points to the risks of extreme heat to maternal and infant health, mental health and non-communicable diseases such as asthma and diabetes.

One billion people in the world are at risk of heatstroke if the world warms by 2 ° C. Professor Jean Palutikof tells us about his research on actions that can help.

Global Warming Effects To Human Health

The impact of these natural disasters on health does not stop there. From the spread of diseases through floods or global warming, to the disruption of food systems through extreme weather, the effects of climate change will be felt everywhere and will affect most of the world’s communities.

Why Does Climate Change Matter?

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

Rising temperatures threaten water security by increasing evaporation, changing precipitation patterns and causing increased snowfall and precipitation. It could also create difficult conditions for many types of crops and livestock, with the production of important crops (which are the majority of the world’s food) such as corn, rice, wheat and soybeans continuing to decline. .

Sustained increases in food production and food availability, combined with a decline in dietary diversity, are associated with increased malnutrition in many communities. And the hot weather also creates a good environment for the growth of food and water diseases.

If the temperature rises above 2 °C, regions that depend on the melting of glaciers and snow could see a 20% reduction in water supply for agriculture after 2050. In Asia alone, 800 million people depend on glaciers for get their water. .

These conditions will worsen as the world continues to shrink, reversing years of progress in the fight against food and water scarcity that still affects the world’s poorest communities. suffering from poverty.

Climate change is changing the world’s waters. Read on to understand how this trend affects the world.

Climate change is the main reason for the emergence of diseases in new regions of the world. The survival, reproduction, abundance, and distribution of pathogens, vectors, and hosts may be affected by changes associated with global warming.

Global Warming Effects To Human Health

Extreme weather can create favorable conditions for the spread of diseases, such as cholera. And as temperatures rise around the world, diseases that were once confined to tropical regions are also expanding their reach.

Climate Change And Health In Pictures

Many emerging diseases appear in these tropical regions where the temperature is suitable for the life cycle of the bacteria and vectors. Pathogenic bacteria pose a risk to human health. And now they are growing.

For example, as the climate changes, mosquitoes and the diseases they carry (such as malaria, dengue, zika) may spread and live in higher altitudes, while increased precipitation may improve the availability of breeding grounds for vectors. . This will increase the number of people in the world who are infected with these deadly diseases.

Learn more about how global warming is allowing many diseases to expand their reach, putting the health of millions at risk.

Climate change and rising temperatures are associated with an increase in allergens and pollutants in the air we breathe. This can present a number of health risks:

These effects on air quality will not be the same all over the world. For example, drought-prone areas are more likely to experience poor air quality due to wildfire smoke or dust rising from the ground, while cities may have air pollution from transportation and commercial burning.

The effects of global warming are affecting every aspect of society – from the food we eat and the cities we live in, to our jobs, our physical activities and our politics.

This has already happened. In 2020, 295 billion working hours were lost due to extreme heat and at least 7 million people were displaced by natural disasters.

The complex effects of these outcomes on physical and mental health are difficult to measure and are often associated with countless risk factors. However, as the world continues to cool, risks from direct and indirect risks from sea level rise and climate change will become more apparent.

Over Half Of Known Human Pathogenic Diseases Can Be Aggravated By Climate Change

Jane Bracher reflects on the impact of floods and climate change on her daily life growing up in the Philippines.

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

Those most at risk are people and places that cannot adapt. 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 limited.

Cities will also be particularly vulnerable, as many hazards such as extreme heat, air pollution and urban flooding are often exacerbated. About half of the world’s population lives in cities, but these health impacts will be most concentrated among residents of socioeconomically disadvantaged areas.

What Climate Change Does To The Human Body

For example, a recent report shows that Delhi is one of the most vulnerable cities in the world, where communities are expected to experience extreme heat, heavy rainfall and urban flooding. , while air pollution is already the cause of almost one. in the world. five died in India.

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

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

Global Warming Effects To Human Health

Even if we succeed in reducing emissions and achieving the goal of zero emissions globally by 2050, the latest IPCC report published in March 2022 notes that many of the effects of global warming are now “irreversible”. These changes will continue to affect our environment in the long term. Therefore, to protect people’s health in the future, it is important that we also adapt to the ongoing climate change.

Levels of standardization have increased in recent years, but progress is uneven and slow. And right now, most climate finance is dedicated to the important task of reducing greenhouse gas emissions. More political and financial support is needed to help people around the world adapt to the effects of climate change.

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

We fund critical research into the impact of climate change on human health globally, at the national, regional and global levels.

There are currently no open opportunities for climate and health grants. Learn more about the money we offer. Although we often think of human-induced climate change as something that will happen in the future, it is an ongoing process. Today, the environment and communities in America and around the world are being affected.

Global temperatures increased by about 1.98°F (1.1°C) between 1901 and 2020, but climate change means more than just an increase in temperature. This also includes sea level rise, climate changes such as droughts and floods, and much more. The things we depend on and value—water, energy, transportation, wildlife, agriculture, ecosystems, and human health—are affected.
