Even 5-10 years ago, there was an active debate about global warming, even in the scientific community, but now no one doubts the danger of this process. People around the world are witnessing how climate change is damaging the planet. Steadily rising average temperatures are causing increasingly intense wildfires, hurricanes and other disasters that cannot be ignored. And while the world is plunged into a deadly pandemic, scientists argue that global warming is the most serious threat in human history. The head of the World Health Organization, Tedros Ghebreyesus, said in a statement in August that "the risks associated with climate change can outweigh the risks of any single disease." And, apparently, there is no exaggeration in these words. More than 200 medical journals released an article on September 5 stating that an average temperature rise of just 1.5 degrees Celsius compared to pre-industrial times would pose the greatest threat to human health worldwide.

Climate warming is more dangerous than coronavirus

Despite all the danger posed by COVID-19, the authors of the article argue that global warming requires the same urgent action as COVID-19. Air pollution is the primary hazard. Burning fossil fuels, which increases the carbon dioxide in the atmosphere, also causes irreparable harm to human health. Polluted air contains small particles that enter the lungs and may even enter the bloodstream. This in turn leads to strokes and heart attacks. They can also damage organs or provoke an inflammatory response from the immune system that tries to fight them.

Air pollution is estimated to cause 3.6 to 9 million premature deaths a year. This is about the same as the number of deaths annually from smoking. In fact, we all become smokers, only we inhale not nicotine, but dirty air.

According to Kari Nado, director of the Sean N. Parker Center for Allergy and Asthma Research at Stanford University, people over the age of 65 are most exposed to the harmful effects of air pollution, but not only them. Smokers and children with asthma are also at significant risk.

As a result of air pollution, about as many people die every year as from smoking.

Air pollution can be equally serious for people with allergies. Carbon dioxide increases the acidity of the air, as a result of which it carries more pollen from plants. Moreover, even healthy people may experience bouts of allergies if the pollen level is much higher than the permissible limits. In 2016, in the Australian state of Victoria, a severe thunderstorm combined with high levels of pollen in the air caused many perfectly healthy people to experience severe asthma attacks.

Heat waves kill

Heat waves are no less dangerous for people. The human body is not adapted to withstand temperatures above 37 degrees Celsius. The heat literally destroys the muscles. The body has several ways to deal with heat, such as sweating. However, when an abnormal heat persists on the street for a long time, the body is unable to resist it.

When a person is exposed to extreme heat for too long, a host of problems start simultaneously throughout the body. The heart has to work hard to pump blood to the rest of the organs, while sweat sucks out the minerals it needs, such as sodium and potassium, from the body. This can lead to heart attacks and strokes. Earlier, I also talked about how high temperature activates multiple sclerosis.

Global warming could lead to hunger around the world

Global warming and the risk of hunger

One of the possible consequences of climate change is food supply problems around the world. Climate change is reducing yields as a result of rising temperatures, changing rainfall patterns and various extreme weather events. Meanwhile, studies have shown that increased levels of carbon dioxide in the atmosphere can reduce the levels of zinc, iron and protein in plants, which are nutrients that humans need to survive.

Climate change is also threatening the supply of seafood. Rising ocean temperatures have caused many fish species to migrate to the poles of the Earth in search of cooler waters. The resulting decline in fish stocks in subtropical regions is of great importance for nutrition in coastal regions. Many of them depend on fish, which is the main source of protein for people here. Poor diet in turn causes many diseases, including heart disease, cancer and diabetes.

Dangerous epidemics and pandemics in the future may become more frequent

The spread of infectious diseases will be rampant

As the temperature rises on the planet, ticks and mosquitoes expand their regions of residence. These insects are well-known vectors of diseases such as Zika virus, dengue and malaria. According to scientists, previously dangerous insects were found only near the equator, but now, due to warming in Northern Europe and Canada, the Zika virus has begun to occur in regions where it was not even suspected before.

In addition, climate change is increasing the risk of the spread of waterborne diseases such as cholera and typhoid fever. In addition, drought reduces water supplies in many regions. In this regard, sanitary conditions are deteriorating, which can also serve as a catalyst for outbreaks of various epidemics.

Scientists also fear that due to the melting of glaciers, previously unknown dangerous bacteria, which have been trapped in ice for thousands of years, will enter the world's oceans. By the way, scientists have proven that bad news is also detrimental to health, and humor, on the contrary, strengthens it.

Therefore, there are indeed reasons for concern. However, hope is not lost yet. According to scientists, the observance of the Paris agreements will allow taking the situation under control.
