The issue of climate change has provoked much controversy lately. While some people believed that climate change is simply the natural warming and cooling variations in climate system, it seems that human activity is contributable to that phenomenon, especially to the extent of greenhouse effect. Greenhouse effect is known as a naturally occurring process that aids in heating the Earth's surface and atmosphere. In actuality, it is undeniable that the enhanced greenhouse effect is mainly caused by human activities, including the combustion of fossil fuels and deforestation. The first problem to be elaborated is that the combustion of fossil fuels in industrial activities and transportation directly leads to the increased greenhouse effect.
Nowadays, as a part of the human activities, CO2 is produced in large amounts due to the industrial activities. There are four main sources responsible for the production of carbon dioxide into the atmosphere: combustion of fossil fuels, transportation and industry. The first source of emission of CO2 is burning of petroleum and fossil fuels. During the process of combustion of fossil fuels, Carbon reacts with the oxygen resulting in the production of Carbon Dioxide. For example, in order to generate electricity, fossil fuels are burned.
Carbon dioxide gas is identified as one of the most important gases that contributed to greenhouse effect. What is greenhouse effect? Greenhouse effect is the trapping of the sun’s heat energy in Earth’s lower atmosphere due to great transparency. It increases the temperature of the earth globally and causing various critical problems such as climate change and melting of polar ice caps. Carbon dioxide is mainly produced by burning of fossil fuel either by cars or factories.
These include volcanic forcing, solar forcing, solar variability and the industrial chemicals. The cause of our current climate change issue is from human beings. Anthropogenic variables is the leading role of climate change today.Climate change currently is caused by the increase of greenhouse gases in earths atmosphere. The increase of greenhouse gases is driven by man made forces. In the industrial revolution the amount of greenhouse gases like Carbon dioxide increased.
Global warming is a serious problem that refers to having too much carbon dioxide in the atmosphere. This problem interacts as a blanket, trapping the heat and warming inside our planet. Humans are used to burn fossil fuels such as oil, natural gas and coal for energy or log and burn the forests for creating new other products. The atmosphere by that is overloaded with carbon dioxide emissions (Climate Hot Map, 2011). There are some specific waste and agricultural management practices that increase the burden on earth by releasing other global warming gases.
Ever since the Industrial Revolution, the production of carbon dioxide which is a greenhouse gas has been increasing tremendously. By far the biggest factor causing to climate change is the burning of fossil fuels for electricity and transportation. This process takes carbon that has been underground for millions of years. Later, it moves into the atmosphere, as carbon dioxide, where it will influence the climate for many centuries into the future. So, now it’s pretty obvious that it all comes down to
As a result, heat from the sun is trapped in the atmosphere and making the planet really hot. Since 1880, the global temperature has been increasing. Many people know that the Earth is warming due to the greenhouse gases, and this is true. Although global warming increases the temperature of Earth’s surface, global warming does more apart from warming the Earth’s surface. It changes the climate, raises the sea level, affects the nutrition of plants, and causes more extreme weather.
When these gases are emitted from the Earth and traps more heat, it is called the Greenhouse Effect which leads to a rise in temperature. This then contributes to the issue of Global Warming.” (“Short Summery for the greenhouse effect”) http://www.landlearnnsw.org.au/__data/assets/image/0012/301332/greenhouse-effect.jpg Causes and the Environmental impact of Global warming Deforestation Deforestation refers to the removal of trees in a forest. This is one cause of global warming because humans want to gain fuel and wood so that they can use the land for buildings or farms. However, deforestation can occur air pollution and hazes just like the situation in Singapore now. This is very harmful to humans and the environment.
Environment: Global Warming Recently global warming became a hot topic to debate about. There are people who believe in it and are continuously worried about the environment and our future, and the others who think that it is just a made-up story to mask other bigger problems. But what is it, exactly? Global warming is a gradual rise in the overall temperature affected by increased levels of carbon dioxide in the Earth’s atmosphere (“Global warming”). Global warming should already be recognized as a real threat from human activity to our planet, and should be researched more, since it might greatly affect our future if left unnoticed.
1. Introduction: Carbon dioxide (CO2) is one of the important green house gases (GHGs) emitted in the atmosphere through various human and natural activities. The human activities include rapid industrialization and urbanization, deforestation, excessive use of fertilizers in agriculture, excessive use of fuels, papers and many other manmade resources whereas natural activities include volcano eruption, forest fires, earthquakes etc. Emission of GHGs in the atmosphere leads to global warming which is one of the primary reasons behind the atmospheric changes that affect the human life directly or indirectly. The consequences of global warming are extremely harsh seasons, untimely rains, extended summers and floods that results in human deaths, destruction of flora and fauna in addition to the huge economical losses.
