Ozone Hole and Global Warming are two different things. It would be wrong if anyone say – both these are same processes. By ozone hole, we mean the decrease of the ozone layer in stratospheric and other regions around the earth. Because of this thing, a large number of sun’s ultraviolet radiations reach to earth and cause various harmful effects. And global warming can be defined as the process of increase of earth’s temperature. The increase of temperature is greatly linked to the high amount of CO2 which is produced from human beings and from burning of plastics and other things. And about the question, ozone hole contributes only 5% to earth’s global warming. Read this article and learn about the Ozone Hole and Global Warming.
What is Ozone Layer and why it is depleted?
The ozone layer is founded in southernmost regions of the stratosphere. Stratosphere is the layer above an important layer (troposphere). This layer was founded in 1913 by two physicists – Henri Buisson and Charles Fabry. It is this layer that protects Earth from sun’s harmful UV rays. But, now this layer is being depleted more and more. Most of the dangerous ultraviolet rays reaches the 7 continents and lead to loss of plant, animal and bird species. Not only in human beings, but skin cancer and cataract also occur in animals because of sun’s UV rays. The harmful effects of ozone depletion have even lead to complete loss of biodiversity. Bromine and chlorine are the two specific gases that lead to ozone depletion. These gases come from CFCS, halons, HFCs that are used in air-conditioners, fire extinguishers, aerosols, fertilizers, and coolants. And natural causes of ozone depletion include sunspots and volcanic depletion. Due to the increase of different man-made activities, ozone depletion has increased by 5% in the last decade. The ozone hole has even lead to melting of glaciers in some countries.
What is Global Warming and why it occurs?
The warming of Earth’s atmosphere is known as global warming. The process in which several greenhouse gases such as nitrogen, carbon mono dioxide, chlorine, methane, etc. combine to heat the world is known as global warming. The sun absorbs these greenhouse gases and increases the temperature by several degrees. By the term greenhouse effect, we mean the process when the Earth’s temperature reaches above the freezing point. Once the gases enter the atmosphere, they remain there for years and even decades. Nitrous oxide, methane, and carbon dioxide are three common gases that contribute to global warming. The most common reason behind global warming includes burning of fossil fuels such as coal and petroleum. Another reason is the cutting of trees and removing vegetation. This process is commonly called deforestation. Moreover, the use of fertilizers that produce nitrous oxide and air pollution lead to global warming.
Is Ozone Hole a Reason For Global Warning?
Strictly speaking, ozone hole does not contribute a lot to global warming. Nevertheless, ozone uses the sun’s ultraviolet radiations for providing energy. But, this heat accounts very less i.e., (only 1%) in the total solar energy that reaches out atmosphere. So, the reaching of UV rays from Sun can be described as a particular cause for global warming. These are the activities like deforestation, burning of fossil fuels such as petroleum, coal, etc., using of fertilizers and throwing non-biodegradable products in the atmosphere contributes to global warming. So, it is necessary to neglect these activities for avoiding global warming.Continue reading to also know more about success tips for engineering students.
You do not need to mistaken global warming with ozone depletion. The ozone layer, a particular layer present in stratosphere helps in avoiding harmful ultraviolet radiations. CFCs and other chemical compounds contribute to ozone depletion and thereby lead to loss of plants, wildlife, and even entire biodiversity. Global warming can be defined as the increase of the average Earth’s temperature. You need to limit the burning of fossil fuels and deforestation activities for preventing global warming. It is not the ozone hole that contributes to global warming, but it is the use of fertilizers, burning of fossil fuels that lead to global warming.
