Notes on Global Warming And Ozone Layer

Previously, people assumed that global warming is caused by the widening hole in the ozone layer. But current study shows that increasing the number of holes in the ozone layer does not increase the temperature. But both of them are the results of increasing carbon footprints, human activities that increase pollution etc.

Although, depletion in the ozone layer is not solely responsible for the alarming increase in temperature. But both of them are considered a huge threat not only to humanity but to the whole earth and its living beings. 

What is global warming?

Generally, the environmental phenomenon of rising heat and humidity increasing every year is called Global warming. This temperature rise has a huge impact on polar glaciers. Every year this elevating temperature melts a significant amount of glaciers.

This unhealthy rise in temperature is a big threat to earth and makes the atmosphere of earth difficult to live in day by day. This phenomenon results from an excessive amount of carbon in the outer atmosphere. Some human activities like increased use of CFC products like refrigerators, air conditioners, cars, spray cans, etc., burning natural gases, coal and oil, etc are mainly responsible for it. 

Causes of Global Warming

The alarming rise in temperature is not a natural occurrence. These high levels of heat and humidity are becoming a life threat for the living creatures on earth. And behind the immense rise in temperature, there are several reasons. Here we are listing some major causes of global warming.

• Carbon Footprints – Generally, an increase in carbon footprints refers to the increasing population of human and other living creatures who participate in the rise of carbon levels of the atmosphere by releasing carbon into the environment ( like when humans enhance their lifestyles, it is responsible for more release of carbon). 
• Pollution – The increasing pollution levels are another major cause of global warming. When the different elements of the atmosphere like hydrogen, nitrogen, carbon dioxide, carbon monoxide etc., rise or decrease unnaturally causes pollution.
• Deforestation- Deforestation is one of the primary reasons for the unnatural rise in temperature worldwide. As modern society thrives and the project of a more civilized surrounding gets more priority, cutting trees and eliminating forests have become common practices. Trees play a pivotal role in keeping carbon dioxide levels in the air in check. But fewer trees indicate a higher level of carbon dioxide resulting in temperature rise.
• Increased Greenhouse gases- Greenhouse gases like carbon dioxide, carbon monoxide, CFC etc., are naturally present in the air. Still, abnormally increased levels of these gases cause the temperature to rise unnaturally. 
• Industrial causes- It is well known that industrial wastes produce the majority of the pollutants on earth. Also, they release a large number of Greenhouse gases which cause global warming.
• Agricultural causes-  Many farmers these days use chemical-based pesticides and fertilizers for agricultural purposes that are very harmful to our environment and pollute the air, water and soil. That is why they have a great amount of responsibility for global warming.

What is the ozone layer?

Earth’s atmosphere has many layers, and each layer has its unique features. The ozone layer is a crucial part of the atmosphere. It is a part of the stratosphere (a layer of the atmosphere). The ozone layer works as a shield for the earth and reflects most of the UV rays produced by the sun. 

It protects the earth like an umbrella and interrupts harmful UV or ultraviolet rays to reach the earth’s surface. Therefore, the ozone layer also helps maintain the earth’s natural temperature. 

Global warming and ozone layer depletion

Global warming and ozone layer depletion are environmental phenomena that are closely intertwined. The term ozone hole means depletion in the ozone layer. This layer works as a protective layer of earth and helps absorb an excessive amount of UV rays, CFCs, Halon gas etc., that are harmful to living creatures of the earth. Depletion in the ozone layer can create various severe health problems.

Increased Greenhouse gases, heat, pollution etc., are causing global warming and depletion of the ozone layer. Also, UV rays entering the earth’s atmosphere because of ozone layer depletion increases the temperature of the earth. So, both of these alarming environmental phenomena result from human activities like pollution, carbon release, deforestation, increased Greenhouse gases etc. 

Conclusion

Global warming is a major problem in the modern-day world. The unnatural rise in heat and ozone layer depletion is mainly responsible for the environmental crisis we are facing today. This also greatly hampers the conditions for living creatures. 

It affects the season cycle, rainfall, and air quality to a large extent. Humans are mostly responsible for this abnormal peak in heat and climate crisis. So it is in our hands to take the necessary measures to save our environment from destruction.
