Effects of increased Greenhouse Gas Emission
While other planets in the solar system are either bitterly cold or scorchingly hot, Earth’s has a relatively stable and mild temperature. And all the living creatures on Earth survive and enjoy this temperature because of the planet’s atmosphere, which is a thin layer of different gases that cloak and protect the planet.
According to research, in the last few centuries, humans have changed the atmosphere of Earth in dramatic ways. This is due to the increased greenhouse gas emission in the past two centuries. One of the main effects of this increased greenhouse gas emissions is global warming which has a drastic effect on the ecology.
What is Greenhouse Effect?
The greenhouse effect is the process by which radiations from Earth’s atmosphere warms up the planet’s surface above what the temperature would be without the atmosphere. In simple words, it increases the temperature of the planet by trapping heat in the atmosphere
Effects of increased greenhouse gas emission
Increase in different greenhouse gases has different effects such as global warming, smog pollution, ocean acidification, ozone layer depletion, changes in growth of plants, etc. Some effects of increased greenhouse gas emission are described in the points below.
● Global warming
Since the start of Industrial Revolution, greenhouse gas emission levels have been increasing. But due to the fast development in the last few decades, the greenhouse gas emission has increased by about 80%. The heat trapped due to greenhouse effect increase the surface temperature of earth which causes global warming. Global warming has harmful effects on the environment in different ways such as the increased melting of ice, rising sea level, desertification, climate change, etc.
● Smog pollution
Due to the increase in nitrogen oxides and methane over the last century due to excess human emission, the ozone concentration has become two times larger. Ozone is the main air pollutant that contributes to the formation of smog which is very harmful to humans, animals, and even plants.
● Ocean acidification
The increase in greenhouse gases like carbon dioxide is causing ocean acidification. Since the Industrial Revolution, the Earth’s ocean water is 30% more acidic than it was previously. The seas and ocean serve as a sink for this gas and absorbs about 1/4th of carbon dioxide emission.
These excess carbon dioxides then have some chemical reactions with the ocean water and form carbonic acid making the ocean acidic. Due to the excess emission of carbon dioxide in the atmosphere, the ocean is getting more acidic day by day which is harming the ocean ecology.
● Ozone Layer Depletion
The main cause of ozone layer depletion is nitrogen oxidewhich is also the most important ozone-depleting substance. CFCs and many other greenhouse gases are also contributing to ozone layer depletion. Due to the ozone layer depletion ultraviolet (UV) rays enter directly in the earth’s atmosphere which causes harmful effects like cancer and other diseases.
