Global climate change threatens your health more than any disease

Author: AMY MCKEEVER Compilation: Red Queen Morning Fish Warm reminder: It takes about 8 minutes to read this article. In 2021, the Director-General of the World Health Organization (WHO) issued a statement that the health threat posed by climate change far exceeds any disease. Yes, you read that right, any kind. In the same year, more than 200 medical journals jointly published an editorial, calling on people to deal with climate change with the urgency of dealing with the new crown epidemic. Global warming is like an ambush, affecting everyone's health from various aspects. Air Pollution Speaking of air pollution, you will definitely think of smog. Respirable particulate matter from burning fossil fuels can travel through the lungs and heart, and even into the bloodstream, triggering strokes and heart attacks. These tiny particles can harm organs, or stimulate the immune system, triggering an inflammatory response. Air pollution is estimated to cause 3.6 to 9 million premature deaths each year. In Ulaanbaatar, poor people in the city burn coal for heating, causing severe air pollution in winter. The study found that urban children had 40 percent lower lung function than rural children.

A hay fever allergy sounds like a ailment, but it can lead to deadly asthma. At least 10 people died in Australia in 2016 when a thunderstorm combined with a large amount of pollen triggered an asthma outbreak. Climate warming has also made wildfires more frequent, and the various harmful chemicals burned by wildfires will produce toxic inhalable particulate matter, which is very small and can easily penetrate deep into human lungs and other organs after being inhaled. Wildfires burn through forests on Fraser Island, Australia.

In extreme heat, the heart has to work too hard in order to send blood to other organs, and the extreme heat itself can cause damage to heart muscle cells, increasing the risk of heart disease. A study published in the Chinese journal "Environment and Health" showed that a 1°C increase in the daily maximum temperature in spring and summer will increase the number of emergency visits for cardiovascular and cerebrovascular diseases by 17.3%. US, Doroteo Jiménez holds a photo of his late niece Maria Isabel, who died of heatstroke after nine hours of work outdoors in the scorching heat.

Extreme heat has also been linked to premature birth and other pregnancy complications for reasons that are not yet known, but it may be that extreme heat reduces blood flow to the fetus. Crops are declining due to climate change, according to a report from the Intergovernmental Panel on Climate Change (IPCC) on ecology and climate. The increase in carbon dioxide will reduce the zinc, iron and protein content of plants. Rising ocean temperatures have allowed fish to migrate to cooler, high-latitude oceans, reducing fisheries production in subtropical regions, and aquatic products are an important source of protein. In short, food is not only decreasing, but its nutritional value is also deteriorating. As the climate warms, other animals, such as ticks and mosquitoes, thrive. They are able to live in a wider range of environments, which also exposes more people to the diseases they transmit, such as Zika, dengue and malaria. Global warming has led to an increase in extreme weather, raising the risk of some diseases that are spread by dirty water, such as cholera, typhoid and parasites. Because floods contaminate water sources, or droughts force people to drink dirty water. Indians are smoking to kill mosquitoes. High temperatures and rain brought about by global warming can promote the breeding of mosquitoes, which in turn promotes the spread of infectious diseases such as malaria. PHOTO: RAJ K RAJ, HINDUSTAN TIMES VIA GETTY IMAGESSocial Issues Global warming increases the probability of extreme weather, and natural disasters such as wildfires, typhoons, and floods are bound to accompany man-made disasters. Many people lost their hometowns and even relatives in the disaster, and the huge psychological trauma can lead to post-traumatic stress disorder and even suicide. Another cruel fact is that climate change is particularly harmful to economically underdeveloped regions and populations. According to a report released by the Environmental Protection Agency (EPA), economically disadvantaged minorities are more likely to live in areas with a high risk of death from heat. Some developing countries, which emit very few greenhouse gases, bear the most of the consequences of climate change. In Central Java, a family's house was flooded. For people like them who live near the sea and in low-altitude areas, rising sea levels will directly swallow up their houses and farmland.

As Lao She said, the rain is not fair, because the rain falls on an unfair world. Is there any hope for us? The relationship between global warming and health is a poorly understood area that is still being studied by scientists and environmental activists. At the same time, people are thinking about ways to save more lives from global warming. Examples include establishing early heat warnings and dedicated cooling centers to shelter people from extreme heat, building more resilient supply chains, and freeing medical facilities from reliance on the grid before power outages threaten many lives.

In the Paris Agreement, countries around the world pledged to reduce emissions and keep global warming below 2°C. Ding Yihui, an academician of the Chinese Academy of Engineering, said that climate warming cannot be stopped or reversed. The health threat of a warming climate has fallen on everyone, and we can only do our best to prevent things from getting worse.
