Global warming is the increase in the temperature of the earth’s atmosphere and oceans. It is a change that is thought to be irreversibly changing the earths climate. Some people say global warming is a (hoax) and that it is a natural cycle that the earth goes through, but the evidence that supports the theory that humans are the driving force of global warming is just too significant to disregard. Most scientists believe that global warming has been triggered by human expansion of “the greenhouse effect”. This warming takes place when the atmosphere traps heat discharged from earth to space. Certain gases allow the atmosphere to act as a door that only opens inwards, it allows the heat to enter but thwarts it from leaving. The accumulation …show more content…
There are a number of factors that allow scientists to believe that human activity is the source of climate change. Carbon emissions are the main cause of global warming. When human beings burn carbon based fuel like coal and gasoline for energy, the carbon dioxide they release is lighter than the carbon dioxide from other sources. The level of lighter carbon dioxide has increased drastically in the last 40 years. Another cause of global warming is deforestation. It is clearing earth’s forests on a massive scale, often resulting in damage of the quality of the land. Forests are being cut down because humans have become very dependent on wood and paper products, livestock are forced to overgraze on former forest lands. Forests are vital because they remove and store carbon dioxide from the atmosphere, this means deforestation releases a lot of excess carbon dioxide and it reduces the amount of carbon detainment. According to the United Nations ‘Food and Agriculture Organization’, 18 million acres of forest, which is roughly the size of Panama, are lost each year. The overabundance of chemical fertilizers in crop lands is yet another cause of global warming. Towards the end of the 1900s, the use of chemical fertilizers had grown drastically. The increased usage of nitrogen rich fertilizers has negative effects on the heat incarceration of the crop land. Nitrogen oxide has 300 times heat trapping potential per unit of volume. The run-off of the residual fertilizers creates what is referred to as “dead zones” in the oceans. In addition to these side-effects, these fertilizers implanted within the earth cause a perturbation towards human
The government has passed many conservation policies to protect animals, eco-systems, plants and trees itself and indigenous people’s way of life, but many of these policies get overlooked and require a lot of extra work. How it affects the rest of the world- This action is permanent, and all of the world is targeted as a potential setting for deforestation. It is predicted that the continuing action may result in very few rainforest across the entire globe. Cutting trees can also be harmful to our ozone layer, which protects earth from dangerous radiation.
When deforestation occurs, the wood of trees releases extensive amounts of carbon dioxide that only adds onto the greenhouse effect. An example of deforestation comes in the form of urbanization and the act to industrialize further within a country. In the last thirty years, India’s forest only covers 21 percent of the nation (23,716 Industrial Projects, 2016). Based on governmental information and data, lands are being curbed aside in order to organize commercial projects. These acts aren’t just happening in India.
IMPACTS OF GLOBAL WARMING ON THE ENVIRONMENT SLINDILE.C MAZIBUKO 215011983 UNIVERSITY OF KWAZULU NATAL WESTVILLE CAMPUS DURBAN, SOUTH AFRICA ABSTRACT One of the biggest problems facing the world today is global warming. It is evident that there is climate change around the world. In recent years, we have so many unusual hurricanes, typhoons, floods, droughts and earthquakes. Plants and animals that lived in the cold climates are now disappearing.
B. Thesis: The causes of global warming and climate change are because of increased emissions of greenhouse gases, and the effects of this are rising temperatures and more severe natural disasters. II. Body A. Counter Claim: Most scientist and people believe that humans are the cause of global warming because of the emissions that they put into the air, but there is a small percentage of people who think that global warming is not caused by emissions at all.

So What Causes It? Global warming occurs when greenhouse gases, such as carbon dioxide, nitrous oxide, and methane trap heat inside the earth 's atmosphere. Think about what happens when you open your car door after the windows have been rolled up on a hot day.
What is global warming? Global Warming is the increase of Earth 's normal surface temperature due to impact of greenhouse gases such as carbon dioxide radiations from lighting fossil fuels or from the removal of trees which lure heat that would otherwise get away from Earth. This is a kind of greenhouse impact. Global warming is the determined and relieved increases in the mean temperature of Earth atmosphere and oceans.
There can also be many causes in disruption of habitats and this can lead to many animal species to extinction. Global warming is a rise in the surface temperature of the earth. The issues that cause Global warming are divided into two categories natural and human influences. There are some natural reasons why Global warming is occurring. The climate has continuously
Global Warming Proposal Introduction The phenomenon of constant increase in the earth’s temperature is known as global warming. The excessive use of fossil fuels is destroying our environment as well as wildlife. It is a great threat to human life too, as this activity is causing intense pollution and also results in damaging the ozone layer.
Do humans cause global warming or is it natural? Many researchers, scientists, and environmentalists are expressing concerns about changes in the overall climate of the `earth. Some believe that a dramatically dangerous warming is taking place in the overall global climate, a problem that is referred to as "global warming”. What is global warming? Global warming is an increase in the average temperature at Earth's surface (“global warming”).
Well the cause of Global Warming isn’t all man made, but the most
Furthermore, the human activity such as burning of the fossil for the essential electricity is also the primary source of increasing climate change in the world (Ranwala & Miller,
Global warming also referred to as climate change is the gradual increase in the overall temperature of the earth 's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants in the air today. There are two causes of global warming, human influences and also natural causes. Global warming is increasing day by day because of all the natural causes going on. A greenhouse is a glass building that contains plants in it that needed to be protected from cold weather. These greenhouses attract heat from many things like the
Perhaps less obvious but no less ominous a threat to the environment are the general increase in temperatures worldwide and the resulting climate changes. This phenomenon, known as global warming, could have serious negative effects on humans and all other living things on Earth. Global warming is a complex problem, and governments have had great difficulty deciding how to address it. Some people think that it is the work of the world where nothing we do can ether change it or anything we do will prevent it. While others say that the
Arguably the most significant thing humans have done to cause climate change is the drastic increase in CO2. As a result of human activities, carbon dioxide, methane, nitrous oxide, and the halocarbons (a group of gases containing fluorine, chlorine, and bromine) build up in the atmosphere over time, as well as the natural sources of CO2, like vegetation. The concentration ofCO2 has went from 280 to more than 380 parts per million in just two hundred years. Still currently rising, the burning of fossil fuels by humans will continue to cause global warming and climate
What is global warming? Global warming is defined as “ an increase in the earth 's average atmospheric temperature that causes corresponding changes in climate, and that may result from the greenhouse effect" (“Global warming”). Natural events and human that causes global warming are believed to be factors to increase in average temperatures. This essay looks into the growing problem of global warming and suggests reasonable solutions to it. It also evaluates the effectiveness of these solutions.
