Humans are not the primary cause of global warming. Although an argument could be made saying that humans have contributed to global warming, it certainly would not be fair to place all of the blame on mankind. From past climate change, it can be proven that global warming is in fact the product of natural causes. Furthermore, the Earth may even begin to cool soon enough.
In the past, there have been changes in the Earth’s eccentricity and the Earth’s tilt which affected how much sunlight was reaching the planet. Changes that happen in the sun can affect the intensity of the sunlight received on Earth. Global warming or cooling can be the result of this.
Furthermore, volcanic eruptions can also contribute to climate change. When volcanoes erupt, carbon dioxide and aerosols are emitted in Earth’s atmosphere. The aerosols emitted can block out sunlight which lowers Earth’s temperature. As many people already know, carbon dioxide has a warming affect on the atmosphere. The carbon dioxide may have contributed to raises in the Earth’s temperature in the past (EPA, 2009).

Human activity plays a moderate effect on global warming. Although we are major source of releasing carbon dioxide through cellular respiration, I do not believe it causes an imbalance in our atmosphere. The way humans do affect that imbalance is when deforestation takes place, and start building industrial plants, cars, etc. Think about the amount of industrial building all over the world that needs fuel to run and not to mention all the machinery that is used every day to construct and run
First, during the last few decades the Earth is experiencing greater rate of rising temperatures due to greenhouse gases that are being produced by human activities rather than because of environmental reasons, such as solar or volcanic activities. In 2006 the President of the National Academy of Sciences stated: “There is no doubt that the Earth is warming,” also he added that people are at least partly responsible for these changes in addition to regular factors (Cicerone, par.4). Natural factors have produced climate fluctuations on Earth for several million years. People have effected an atmosphere of the Earth just for nearly one hundred years, since Industrial Revolution has begun (Revkin 340). Of course, it is unfair to say that global warming is caused entirely by humans. For example, people can not have an impact on the position of Earth in relation to the sun, or on the galactic density, or such nature events as air emissions of volcanic gases. As a result of these environmental factors, Earth usually had higher rates of temperature fluctuations during the previous million years than it has in later centuries. On the other hand, people are responsible for the highest concentration of greenhouse gases during the last 650,000 years in the atmosphere due to industrial manufacturing, driven by the increase in consumer consumption (Lindsey, par.
First of all, there are more potent gases being emitted into the atmosphere such as the well known greenhouse gas, methane. Methane is mostly associated with cows. Yes, I said it, cows. When cows fart, they release the greenhouse gas methane. Also, methane heats up the atmosphere more than carbon dioxide. So the point here is that global warming isn't mainly caused by humans.
The levels of carbon dioxide in the atmosphere were 15 times higher than they are today and this was due to the volcanic activity, which released enormous amount of carbon dioxide gas into the atmosphere. The flooding of continents and the lack of plants on land also contributed to the heightened levels. These conditions created a greenhouse effect so tempera...
The rising of temperatures is caused by factors called climate forcing or “forcing mechanisms”. This includes processes such as variations in solar radiation, variations in the Earth’s orbit, mountain-building and continental drift, and changes in greenhouse gas concentration. Solar radiation gets trapped by gases, which are created on earth, in the atmosphere. The radiation comes from the sun towards earth and bounces off the earth’s surface. However much of the radiation gets trapped by the gases remaining behind which warms our planet instead of going back into space like previously. This is known as the greenhouse effect. Some of the major contributing gases are; water vapor, carbon dioxide, methane, and our ozone layer. According to sources at Real Climate, 36-85% of the greenhouse effect is due to water vapor (including clouds), followed by carbon dioxide at 9-26%, and last all the minor greenhouse gas absorbers at 7-8%. Humans contribute to the greenhouse effect by deforestation, land use changes, and burning fo...
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...
Throughout history climates have drastically changed. There have been shifts from warm climates to the Ice Ages (Cunningham & Cunningham, 2009, p.204). Evidence suggests there have been at least a dozen abrupt climate changes throughout the history of the earth. There are a few suspected reasons for these past climate changes. One reason may be that asteroids hitting the earth and volcanic eruptions caused some of them. A further assumption is that 22-year solar magnetic cycles and 11-year sunspot cycles played a part in the changes. A further possibility is that a regular shifting in the angle of the moon orbiting earth causing changing tides and atmospheric circulation affects the global climate (Cunningham & Cunningham, 2009, p.205). Scientific studies suggest that all these played a role in past global warming and cooling periods. Today, however, there is a lot of conflict on whether humans are causing a global warming that could be disastrous to humans and all species of plants and animals on this earth. This paper will first explain the greenhouse effect, then take a look at both sides argument, and, finally, analyze the effect of global warming on world-wide sustainability
The climate on the Earth is changing. Ice age is interleaved with the global warming. In the present age, the temperature of the Earth's climate system continues to rapidly increase and it leads to global warming. Global warming is the process of gradual growth of average annual temperature of the atmosphere of the Earth and World oceans. The average temperature on the Earth was increased by 0.6C. There are various reasons for global warming, such as human activities, natural events, increasing of gases, such as carbon dioxide in atmosphere and solar activity (Global warming).
Humans have caused global warming by doing many things but the main three are burning of fossil fuels and green house gas emission, deforestation, and excessive use of chemical fertilizers. Global warming is like a bad dream going worse.
Climate change has been an extremely controversial topic in recent history and continues to create much debate today. Many questions concerning climate change’s origins and its potential affect on the globe are not fully understood and remain unanswered. What is climate change? Is climate change happening? Is it a natural cycle of the world or are there other catalysts involved such as human activity? What proof is there? What data correlations show climate change is accelerated by humans? How serious is climate change and how will it affect the future of our globe? What are we doing to address climate change? Should we really be concerned about climate change? Questions such as these have made climate change a very serious issue in today’s world and created the ideology of climatism. The issue of climate change has affected many different aspects of our lives and the world we live in. Policymaking, human activism, technologies, emission control, global warming, alternative energy sources and many other things have been greatly affected by the mania of climate change. This research report will present climate change in a light of common sense and rationality that will take a grounded discussion of the science behind climate change, global warming, human activity, and how the ideology of climatism has corrupted and driven the actions to combat climate change.
Volcanic activity also causes the release of certain elements that may block the sun and also contribute to the increase of greenhouse gases in the atmosphere. The most destructive human contribution to climate change is fossil fuel combustion, which results in the release of carbon dioxide and other greenhouse gases into the atmosphere. Increased carbon dioxide, methane, nitrous oxide and halocarbon levels in the atmosphere cause an imbalance in the earth’s energy. This is because the gases alter solar radiation and thermal radiation, which regulate the earth’s energy.
This is based upon the sunlight and volcano eruptions which plays an extreme factor. "Most often, global climate has changed because of variations from sunlight. Tiny wobbles in Earth’s orbit altered when and where sunlight falls on Earth’s surface. Variations in the Sun itself have alternately increased and decreased the amount of solar energy reaching Earth. Volcanic eruptions have generated particles that reflect sunlight, brightening the planet and cooling the climate. Volcanic activity has also, in the deep past, increased greenhouse gases over millions of years, contributing to episodes of global warming." (Global Warming, web.) However, I firmly believe that climate change is not only the result of natural causes alone. I think it is man-made and the major factors are from CO2, factories, and power plants burning coal/ oil, natural gas.
There are other short-term effects, and these effects don’t just take place in the area of an eruption, but expands to other parts of the world. Globally, what has become an issue of its own is climate change. In the Encyclopedia Britannica, Jackson (2013) defined climate change as a “periodic modification of Earth's climate brought about as a result of changes in the atmosphere as well as interactions between the atmosphere and various other geologic, chemical, biological, and geographic factors within the Earth system.” With all of the debris that enters the atmosphere from eruptions, volcanoes can make an impact on climate change. Volcanic activity can cause global cooling, but some sources say that it has the potential to impact global warming as well, due to the amount of carbon dioxide (CO...
Our planet has managed to survive and thrive for about 4.54 billion years. In the last 2 million years we have caused enough damage and destruction to make our world “broken” beyond repair. We will not be able to get back the world we once had. The reason behind this is global warming, specifically, the increase of the global temperature due to the burning of fossil fuels and the release of greenhouse gas emissions into our atmosphere. If we do not make the issue of global warming a priority in today`s society, our entire way of life will be at risk. There are many reasons why so many people believe global warming should be a concern. Thoroughly examined points include: scientific predictions, rising temperatures, human causes, drastic climate changes and animal adaptations. Though there are several points arguing how global warming should not be a concern, the reality of the matter is that it needs to be taken into consideration on a global scale before it is too late, as to do nothing would have devastating implications on humankind.
Global warming is an increase in the earth's temperature due to fossil fuels, industry, and agricultural processes caused by human, natural, and other gas emissions. This results in an increased evacuation of greenhouse gases. “Short-wave solar radiation sinks into the Earth's atmosphere and warms its surface while long-wave infrared radiation emitted by earth's surface is absorbed, and then re-emitted by trace gases.” (2)
