“Global warming is the usually rapid increase in Earth’s average surface temperature, over the past century primarily due to green house gases released as people burn fossil fuels.”(“Cause of Global Warming”) Global warming is a dangerous and complicated issue that not many people know about. Over the past 250 years, people have been releasing greenhouse gases into the atmosphere by burning fossil fuels. Many factors cause global warming, most are by humans. The carbon dioxide over the years has increased much more rapidly now. “Since the industrial revolution began in about 1750’s, carbon dioxide levels have increased nearly thirty-eight percent.” (“Cause of Global Warming”) “ It was not until 1950’s that scientists had discovered that the carbon dioxide levels had increase in the atmosphere and realized it might be a threat. In 1960’s many scientists’ predicted in 2000 the atmosphere would be really bad that it would be the cause of climate change.” (“Global Warming Timeline”) The United States President focused on spreading the news to the nation, but at that time global warming was not a threat so many ignored the signs. However, it was not until 1990 that global warming started to affect the people by climate change. “The effect of climate change on human beings’ health was in focus in 1990s. The issue has not only attracted the experts, but also made the general public worried.” (Moseley Jonathon) Vargas 1 People using cars and factories sending out carbon dioxide in the atmosphere everyday eventually adds up. Scientists have discovered that ninety percent of the global warming is from green-house gases. All the chemicals in the air eventually will start to harm many people and children.

For years to come there will always be a speculation on whether the climate change has really taken place or not. Many believe that large companies launched this topic in order to benefit from it in profit, as there are also those who are convinced that this are consequences that have emerged from human mistakes in understanding the environment. As humans are struggling to trust one another whether it is just a big conspiracy or not or environment changing itself, we are slowly starting to feel the effects of climate change. Because of the gasses (CO2) that are in the air, atmosphere is getting warmer, thereby triggering the Greenhouse effect. Almost 70% of emitted gasses in air are CO2, which leads us to believe that this is the main cause of Global Warming. Since it is billions and billions of metric tons per year that are being released in air, many scientists conclude that temperature will most likely be more higher in twenty years from now, than it was in near past.
Since measurements began in 1958 -- and it can be assumed to have been the case since the industrial revolution -- emission of carbon dioxide into the atmosphere has risen steadily as a result of the burning of fossil fuels (Quay, pp 2344). Although there is much argument over the implications of increasing carbon dioxide levels in the atmosphere, there are several points that almost all scientists would agree on: firstly, carbon dioxide acts to absorb radiated heat; if present in our atmosphere will do just that to some extent. Second, the concentration of carbon dioxide in our atmosphere is rising. Third, the temperature of the planet is rising - although the amount of this increase and the causes of this rise are subject to disagreement (Philander, pp 193).
What are the Causes of Global Warming?
Most climate scientists agree that the main cause of global climate change is the human expansion of the greenhouse effect. This is the global warming that results when the atmosphere traps heat radiating from Earth toward space (climate.nasa.gov). The main gases that contribute to the greenhouse effect include water vapor, carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons (climate.nasa.gov). Human activities are changing the natural greenhouse effect. The burning of fossil fuels like coal and oil has increased the amount of carbon dioxide in the atmosphere (climate.nasa.gov). Carbon dioxide levels have increased from 280 parts per million to 379 parts per million in the last 150 years due to human act...
Firstly, global warming is said to be caused by the high levels of carbon dioxide released into the atmosphere by humans. Smoke produced by factories, vehicular exhaust, and the burning of fossil fuels such as coal in power plants are the primary sources of carbon dioxide. The theory is that carbon dioxide being released into the Earth's atmosphere is steadily building up because it cannot escape into space. The theory as to why the carbon dioxide in the atmosphere actually causes the Earth's average temperature to rise is outlined as follows:
over the last decade. More on that, it is a fact that the burning of fossil
Well it hasn't for the last 800,000 years. Ice core data shows that the fastest rate of CO2 increase over the last 800,000 years was 30 ppm in 1000 years.
Secondly the amount of co2 we have relased into the air has caused global warming. Acording to ¨ Nobel Spaech by Al Gore, 70 million poultion that has caused global warming was released on the day of his speach. Futhermore ,Gore claims
Due to climate changes, we are a “gradual and uncertain rather than immediate and obvious” process, we as humans cannot understand it (Jamieson, 102). In addition, climate change effects have no geographical bounds and because very few people pay attention to events that occur beyond national boundaries, most people are oblivious to its existence. Jamieson makes the point that climate change must be thought rather than sensed, and we as humans are not very good at thinking (Jamieson, 103). On top of that, even if we succeed in thinking that something is a threat, we are less reactive than if we sense that it is a threat. Since we cannot even comprehend climate change's presence in our world right now, it also makes it extremely difficult for us to comprehend how our anthropogenic actions of today will affect future generations all over the world.
furnaces. By letting all these gases release into the air, it makes it harder to breathe.
Nearly all climate scientists can agree, that the most common cause of the current global warming trend, is to be blamed on the burning of fossil fuels, which changes the natural greenhouse of our earth. The usual process in which heat is absorbed by the earth, is when sunlight passes through its atmosphere
As Robert Frost once said, “ Some say the world will end in fire, some say in ice. From what I’ve tasted of desire I hold with those who favor fire.” This excerpt can relate to the idea of global warming. Global warming can be 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. During the past 10,000 years the earth has been in an ever-growing cycle that has significantly changed the climate. These changes are becoming more prevalent in our world today in the past 150 years. Scientists have been analyzing the causes and effects of the greenhouse effect and many other issues that global warming has presented. As John Houghton states in his book, Global Warming the Complete Briefing, on page 2 “ The 1980s and 1990s were unusually warm. Globally speaking, the decades have been the warmest since accurate records began somewhat over a hundred years ago and these unusually warm years are continuing into the twenty-first century.” There are countless records that show that our world as a whole is getting warmer, and the facts cannot be disputed. Everyone in the world today is experiencing the effects of global warming. These effects might be small now, but if we don’t protect our planet now then the consequences will greatly be increased.
The carbon dioxide, also known as a greenhouse gas, remains in the air trapping heat and gradually warming the planet. Other greenhouse gases such as: methane, nitrous oxide, and water vapor also contribute to this slow warming. According to Live Science, The state of these gases being trapped is called the greenhouse effect, which is one of the leading causes of global warming (Lallanillia). All the gases are created differently and have different effects on the earth.
As matter of fact, the increasing of greenhouse gases (GHGs) including water vapor (H2O), carbon dioxide (C...
Climate changes occur in our earth's atmosphere due to a buildup of greenhouse gases. Greenhouse gases can occur naturally as well as a result of human activities. The greenhouse gases are carbon dioxide, methane, and nitrous oxide. “Carbon dioxide is released into the atmosphere when solid waste, fossil fuels, and wood are burned.” (2) The gases help to warm the surface of the Earth. Each greenhouse gas absorbs heat differently. If natural gases did not occur, the temperature of the earth would be considerably cooler. “Problems can occur when higher concentrations of greenhouse gases are present in our atmosphere because they have enhanced our earth's heat trapping capability.” (3)
