In shorter terms, global warming represents a fundamental threat to all living things on earth. Global warming is the term used to describe a gradual increase in the average temperature of the Earth’s atmosphere and its oceans, a change that is believed to be permanently changing the Earth’s climate. There is great debate among many people, and sometimes in the news, on whether global warming is real. But climate scientists looking at the data and facts agree the planet is warming.
While many view the effects of global warming to be more substantial and more rapidly occurring than others do, the scientific consensus on climatic changes related to global warming is that the average temperature of the Earth has risen between 0. And 0. 8 c over the past 100 years. The increased volumes of carbon dioxide and other greenhouse gases released by the burning of fossil fuels, land clearing, agriculture, and other human activities, are believed to be the primary sources of the global warming that has occurred over the past 50 years.
Scientists from the Intergovernmental Panel on Climate carrying out global warming research have recently predicted that average global temperatures could increase between 1. 4 and 5. 8 co by the year 2100. Changes resulting from global warming may include rising sea levels due to he melting of the polar ice caps, as well as an increase in occurrence and severity of storms and other severe weather events. Unfortunately, the imbalance which we have created between our life and earth is already showing the signs disasters in the form of flood, cyclones, landslides, tsunami, drought, etc.
Fifth imbalance continues to rise, one day this will pose a question mark on the existence of this planet. Carbon dioxide (CA) which is an important constituent of environment is causing a warming effect on the earth’s surface. Trees play a significant role in the global carbon cycle. They re the largest land-based mechanism for removing carbon dioxide from the air. Deforestation is checking these positive processes. It is the second principle cause of atmospheric carbon dioxide.
Deforestation is responsible for 25% of all carbon emissions entering the atmosphere, by the burning and cutting of 34 million acres of trees each year. Every day, over 5,500 acres of rainforest’s are destroyed. As a consequence of massive loss of forests, global CA levels rise approximately 0. 4 per cent each year, the levels not experienced on this planet for millions of years. As we know, the forests are he great absorbers of CA. There is a close relation between global warming and population growth. Today the large population on earth is using the technologies which are destructive for the earth.
Approximately, 80% of atmospheric CA increases are due to man’s use of fossil fuels either in the form of coal, gas, or oil. A large portion of carbon emission is attributed to the burning of gasoline in internal-combustion engine of vehicles. Vehicles with poor gas mileage contribute the most to global warming. Besides, the sulfur group gas is the most harmful for this. Its contribution is 30% in global arming. This gas is also emitted from the burning of fossil fuels. Increase in global temperatures will cause rise in sea level.
It will lead to melting of glaciers, changes in rainfall patterns, increased intensity and frequency Of extreme weather. As per the latest survey report the rate of melting of glaciers has seen sharp increase in recent times. Even those glaciers are affected from global warming which have been considered permanent. The shrinking of glaciers is going to pose a major problem of drinking water. One effect global warming has on the environment is it affects sea level. Global warming raises the overall temperature and cause glaciers and ice caps to melt, which makes the water expand.
When this happens, sea levels tend to rise more rapidly than normal. According to the Third Assessment Report by the Intergovernmental Panel on Climate Change, the sea level is expected to rise as much as 88 centimeters in the next century. Wetlands are lost as the level rises. Rise in atmospheric temperature will lead to the outbreak of airborne and water-borne diseases. It would also contribute to the rise in death caused by heat. The problem of drought would be frequent. Consequently, malnutrition and starvation will pose serious challenge before humanity.
Global warming is a great threat to the flora and fauna of the earth. A large number of species may become extinct. The expanse of desert would increase. Low rainfall and rising temperature could add to the intensity and frequency of dust storms. This will immensely affect the quality of agricultural land, ultimately causing adverse effect on agricultural produce. It would have far-reaching economic impact. The growing concerns over global temperatures have led to the nations, states, corporations, and individuals to raw out a plan of action to avert the situation.
As a result, the world’s primary international agreement on combating global warming was reached in Kyoto in 1997, which came to be known as Kyoto protocol. However, ten years have passed and the situation does not appear to be very changed. It seems that the member countries are not very serious about its devastating effects. In addition, forestation can be of great help in this regard. Planting more trees and reducing timber cuts worldwide will help restore the imbalance. Secondly, we must follow on environmental policy of ‘reduce, reuse, recycle’, I. E. Rumoring the reuse of anything.
Thirdly, the use of fuel- efficient vehicles should be promoted as these vehicles have lower emissions of harmful gases. Every individual should be aware of the importance of the protecting environment. Besides, echo-friendly technologies must be promoted, and must be substituted with the technologies which cause great emission of global warming gases. Public awareness campaigns can be of great help in this regard because unless each and every individual is aware, only the governments’ effect cannot bring desired difference. Although global warming is bad, there are ways to try and prevent it.
Just by driving less and taking a bike or walking can help prevent global warming. Cutting down on your garbage can also help, just by buying fewer packaged materials can help prevent global warming. Most importantly, recycling can help. Buying recycled paper products and recycling as much as possible, is a great way to prevent global warming. So many things Can be affected just by global warming, but it can also be prevented. Global warming is considered to be the main problem with our environment. So whether global warming is real or not, lees try to prevent it, because the environment is important!
