The Effects of Global Warming on Humans

Global Warming can be defined as the increase of the earth’s average surface temperature and its ocean due to greenhouse gases released as people burn fossil fuels. These greenhouse gases like carbon dioxide and methane absorb heat that will create a negative effect on the surface of the earth. Global warming has emerged as one of the biggest environmental issues on humans in the last decades. Some of the effects of Global Warming on humans, are Health Risks, Diseases, Climatic Change, Hurricanes Frequency and Rise of Sea Levels, Agriculture, Food Chain, Longer and Shorter Seasons, Economic Collapse, and Decreased Population.

Health Risks are one of the effects of global warming on humans. The rate at which carbon dioxide is trapped in the atmosphere makes breathable air almost impossible. This will cause allergies, asthma, and infectious disease outbreaks to be common due to an increase of growth of pollen-producing ragweed, higher levels of air pollution, and spread of conditions favorable to pathogens and mosquitos.

Diseases are another effect of global warming on humans. As the temperature becomes warmer, it can affect the health of humans because of the diseases they are exposed to. With the rise within the downfall, water-borne diseases are likely to spread. Examples of these diseases are malaria, typhoid, and cholera.

Climatic Change is the third effect of global warming. We are now experiencing irregular weather patterns. Increase in precipitation in the form of rain has been noticed in polar and sub-polar regions. More warming can cause a lot of evaporation which can cause a lot of rains. Animals and plants cannot simply adapt to extend downfall. This may also cause plants to die and animals to migrate to other regions. Also, the disruption of habitats such as coral reefs and Alpine meadows could drive many plant and animal species to extinction. The result of climatic change will cause the ecosystem to be out of balance; this effect can cause famine for humans.

Hurricanes Frequency is a major effect of global warming. As the temperature of oceans rises, hurricanes and other storms are likely to become stronger. With the increase in global warming, the water in the ocean warms up and it heats up the surrounding air, creating hurricanes. The rise of Sea Levels is another major effect of global warming. The melting of polar ice-caps and lesser water evaporating into the atmosphere square measure inflicting enlarged ocean levels. Rising sea levels will lead to coastal flooding on the Eastern Seaboard, like the state of Florida, and in other areas like the Gulf of Mexico. Therefore, hurricanes can be regarded as a climatic hazard for humans.

Agriculture is an effect of global warming. As the global temperature increases, the plant will find it harder to survive higher temperature. As it is known that plants are the major source of food for humans, research has shown that food shortage may occur. Although the results are not yet visible, it may show its effect in years to come. Also, the shortage of food may lead to war and conflicts in some countries.

Food Chain is one of the devastating effects of global warming on humans. Change in time and seasons can cause birds to fly south for winter before time. This could cause hibernation to take longer time, and collapse of animal life. The entire food chain could, therefore, be disrupted.

Longer and Shorter Seasons is an effect of global warming. Global warming is now causing springtime to show up ten days sooner than it has in the past. This could cause flooding from reservoirs filling ahead of time. Also, droughts are not enough to provide adequate nourishment for crops in shorter seasons.

Economic Collapse is also one of the major effects of global warming on humans. The economy could get worse with a decrease in vitality crops, productions, and manufacturing items. Without having a good climatic condition, the food industry will not be able to manufacture enough food for the people. Without the resources to feed the world, manufacturing companies will collapse, and this may cause hunger.

Decreased Population is one the biggest of all the effects of global warming. There is scientific evidence that if global warming increases, the world population would be decreased by 75 percent. With the increasing severity of storms, floods, earthquakes, and wildfires, natural disasters would diminish 1/2 the earth’s population. While the other 25 percent of the world population would be affected by airborne diseases, starvation, and poverty.

Global Warming is already affecting the world. However, there are ways to avoid global warming. According to, in 2015, the United States Environmental Protection Agency has pledged to reduce carbon pollution from power plants by 2030. In addition, another way to avoid global warming is stopping deforestation. Reducing tropical deforestation can lower global warming emissions and plays a significant role in a comprehensive long-term solution to global warming.

In conclusion, global warming is one of the biggest issues the world is facing right now. There are many devastating effects global warming is causing already, and there are more that are yet to come if care is not taken. The world is already experiencing the climatic change which is leading to frequent hurricanes. Health risks are the worst among the effects of global warming because if people are dying frequently because of health issues from global warming, humans are likely to go in extinction. Agricultural effect of global warming is worth worrying about because of the lack of production of food can lead to food scarcity. Economic collapse from global warming can also cause poverty. Finally, global warming is an interesting occurrence, but a serious issue that must be avoided. The government and the people have a big role to play in putting a stop to global warming, so as to save our generation, and the generations that are yet to come from its devastating effects.
