Question

speech writing on global warming

Answer 1

Global warming is the steady and continuous rise in the level of earth temperature. Out earth surface is becoming hotter day by day just because of some unnoticeable habits of human beings all across the world. Global warming has become the most worrying threat for the earth’s atmosphere as it is reducing the life possibilities on the earth day by day through a continuous and steady declining process.

Before planning the solutions of the global warming, we must think about the causes and effects of it on the atmosphere in order to get sure that we are in right direction of getting full relief from this issue. The continuous warming of the earth surface is the increasing emission of CO2 in the environment. However, the increasing level of CO2 is caused due to many reasons like deforestation, use of coal, oil, gas, burning of fossil fuels, burning of gasoline for transportation, unnecessary use of electricity, etc which in turn causes rise in earth temperature. Again it becomes the reason of rising sea level, occurrence of flooding, storms, cyclone, ozone layer damage, changing weather patterns, fear of epidemic diseases, lack of food, death, etc. We cannot blame any single entity for this as each and every human being is responsible for the increasing threat of global warming which can be solved only by the global awareness and kind efforts of everyone.

INTRODUCTION

What exactly is global warming and why is it worthy of consideration? Global warming is the scientific phenomenon linking an increase of the average earth temperature because of a trapping of radiation within the earth like a greenhouse. This has been a natural phenomenon throughout the natural history of the world but it has only become a problem in the last few hundred years because of an anthropogenic increase in greenhouse gasses.

CAUSES

This essay on global warming needs to look at the causes of the problem. Global warming is caused by an acute heating of the earth’s atmosphere as a result of energy being trapped.

Global warming is also largely a result of the release of methane from cracks in the earth, landfill sites and through natural gas leaks. Methane has an effect on the atmosphere which is four times as bad for global warming as carbon dioxide. Cattle and other animals that produce methane can also contribute significantly to global warming, much of this has been a problem because of human animal farming which produces hundreds of cattle for the meat

ANTHROPOGENIC EFFECTS

The reason as to why global warming is such an issue today is because of the problem that humans are creating with anthropogenic contributions to greenhouse gasses. Many of the practices that humans employ create enormous amounts of greenhouse gasses to be released and this has been well documented to be significantly harming the earth. Modernity, modern technology and new lifestyles have resulted in human activities that produce a lot of greenhouse gasses such as deforestation, the combustion of fossil fuels, industrial action

Mining causes methane and natural gas to escape from where it is trapped below the earth. Shockingly, many energy companies around the world that drill for new fossil fuels such as oil can actually end up burning all the natural gas off in the process rather than storing it because it is not economically viable to do so. This creates huge problems as there is a limited supply of natural gas and fossil fuels around the world.

Deforestation is one of the biggest causes of global warming. Not only are trees cut down to make goods that need to be transported using fossil fuels, the removal of trees leads to a net loss of photosynthesis which is carried out by plants to make food. In this process, carbon dioxide can be absorbed and turned into oxygen, making food for the plants and cleaning the atmosphere as a result. The wide scale removal of trees and biodiverse life results in a large amount of carbon dioxide that can’t be converted to oxygen and so a huge problem for global warming.

PROBLEMS

Global warming and greenhouse gasses are problematic as they raise the earth’s temperature, but exact effects of global warming exist and what effect will global warming have for our planet and our society in the future? Polar ice caps can melt, there will be widespread flooding all over the world, there will be an increase in the frequency and intensity of harmful natural disasters and the consequences to the economy will be detrimental to societal progress.

The melting of polar ice caps poses one of the biggest problems for human society. As the earth’s temperature increases, these large masses of ice and snow will melt and create the sea level to rise all over the world. In the same way, glaciers will also melt and create problems on land. According to scientific research, if all the snow and ice were to melt today, this would result in a raised sea level of over 200 feet worldwide and would be instantly detrimental to many low lying areas such as the Netherlands and other low lying islands around the world. It is the tragic case that most of the countries and areas that will be affected directly are often the ones that contribute the

Natural disasters such as hurricanes will be of greater occurrence and this will cause an increase in the economic effects. Hurricane damage alone will result in billions of dollars worldwide needing to be spent to rebuild societies and provide relief. It will be difficult for people and societies to keep up and offer enough support if global warming is too big of a problem. All natural disasters from tornadoes to droughts will all increase in intensity – one can only imagine what a hurricane twice as strong

CONCLUSION

In conclusion there are many causes and effects of global warming. Unfortunately it is highly likely that the problems of global warming will persist unless immediate action is to be taken. Problems will exist unless hard geoengineering is developed or if people are given sufficient incentives to change their actions for the better.
