An American vice president, Al Gore, said that while the reason behind dinosaurs’ extinction over 65 million years ago was because of a giant asteroid, the species that are dying out every minute of our lives are not just because of some havocs, but it is US-human (Al Gore, 2006, internet). We are destroying our world indirectly which means we do not just go and kill those entire animals, but what has caused their extinction is due to “Climate Change” that is the result of the Natural Causes and Human Activities. We used to look at how natural causes have contributed to climate change, but human is now even playing a bigger role in causing climate change.
Climate can be defined as the average weather effected by slow features such as oceans, precipitations, and clouds (Slaght, 2009, p34-41). Out of the two main causes of climatic alterations, natural cause is one of them. It refers to phenomenon such as forest fires, volcanic eruptions that cause tons of pollutants to our atmosphere, but also keeps the world in balance. For example, disasters such as volcano eruptions release at least 130 million tons of pollutants annually. Moreover, studies from the recent volcanic eruptions such as El Chichon, Mexico (1982), and Mount Pinatubo, Philippines (1991) showed that the sulfuric acid liquid drops from these volcanoes also subsidize the depletion of our ozone layer (Volcanic gases and their effects, internet). On the other hand, even if human have not existed on earth, carbon dioxide emission would still happen. Over 95% of the world emission came from what we call the natural cycle of CO2 (Carbon Dioxide) such as the decaying of organic materials, but whatever happens during the natural cycle of the earth’s CO2, it is already in the ...

...s with a couple of solutions and people, but this is a global problem that every one of us has to work hand in hand to solve. The well-being of the world is in our hands and if we keep taking it for granted like what we are doing everyday, what is here for us might not be there for our children in the future.

“All across the world, in every kind of environment and region known to man, increasingly dangerous weather patterns and devastating storms are abruptly putting an end to the long-running debate over whether or not climate change is real. Not only is it real, it's here, and its effects are giving rise to a frighteningly new global phenomenon: the man-made natural disaster.” BARACK OBAMA, speech, Apr. 3, 2006. Climate change is not a theory contrary to what many individuals believe and is in fact confirmed by major scientific agencies such as the National Oceanic and Atmospheric Administration (NOAA) and the National Aeronautics and Space Administration (NASA) in the United States. Global Warming causes are mainly due to greenhouse gases that are trapped in the atmosphere and cause depletion of the earth’s ozone layer. Carbon Dioxide is a greenhouse gas, and although it is a necessary component in our atmosphere as it helps plants perform photosynthesis, too much of it causes ozone depletion and therefore climate change. Carbon Dioxide levels in the atmosphere have increased tremendously after the industrial revolution, which indicates that the major cause of this issue is due to anthropogenic activities.
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...
Humans can not be the only thing that is hurting the Earth. When you really think about it, Earth goes through a lot of natural disasters, which cannot be controlled. According to an activist, Tim Haering, “Tsunamis, floods, volcanoes, earthquakes, tornadoes, wildfires, disease nature kills more than we kill each other.” Earth throws in all of these natural ...

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...
There are so many factors in today’s growing population and its action that contributes to the environment. With the rise in population there is also increase in the needs and demands resulting in more production of food and assets. Most of the actions of human lead to increased environment risks which in return will only effect the livings of this planet. Currently mostly all individuals have at least one form of vehicle for transportation. There is increased industrialization and requires a lot of energy which comes from fossil fuels as the need for oil increases to fuel large amounts of humans daily work and chores. The climate change is no mystery, it is known to be cause of various human actions trying to satisfy their needs while putting
...to artificial costs of resources, it is humans that cause it to happen. Not only do these destructions cause global warming, they also put the health of many in danger as the climate often reflects the health of individuals. The gas permitted into the air by hydraulic fracturing and the chemicals from burning forests can all be breathed in and affect one’s health. Even the act of human terrorism, like the 9/11 terrorist attack in New York City, can cause green-house gases to escape into the atmosphere along with other air pollutants. Driving a car also contributes to the quantity of carbon dioxide emitted into the ecosystem. Individuals do not bother to use alternatives because they tend to choose the more convenient way of life. Human activities such as hydraulic fracturing, rice cultivation, fossil fuel burning and deforestation all contributes to global warming.
Climate change is a major issue that is only going to get worse. Climate change is a change in global or regional climate patterns. It has become more apparent since the mid to late 20th century onwards and is attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels. Climate change has been an important issue for decades that has effects on the environment and people of the world with the end result potentially being catastrophic. Although many believe that prolific use of fossil fuels is the direct cause of climate change, there are many more underlying causes including population expansion as well as irresponsible consumption of natural resources that have
In theory some parts of the world might benefit, from a human point of view, due to global warming. However, at current rates of warming, local ecosystems will collapse and any objective measure of global benefits versus suffering would show much more suffering than benefits gained.
The first part of this essay discusses what the human species has done to deal with the problem of climate change. While some improvements have been made, the problem has not been addressed aggressively enough to stop the damage. What is amazing about this is the denial of so many people that problems exist. If they do realize the risks, they are simply not taking actions to contain the damage.
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.
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 heating and cooling has occurred on a cycle for millennia, however in the past thirty years the increased use of energy and fuels by humans has drastically changed this natural occurrence (Juerg, 2007). The largest cause of this warming is the release of carbon dioxide from the burning of fossil fuels. Carbon dioxide levels are twenty-five percent higher than they were in 1957 (UCS, 2013). This seemingly insignificant change has caused a myriad of negative effects. The endangerment of species, rising sea levels, and increased natural disasters are just a few examples of change brought about by global warming (Juerg, 2007).
The earth is a complex system, which continues to evolve and change. Climate change and global warming are currently popular in the political agenda. But what does “climate” really mean? The difference between weather and climate can be conveyed in a single sentence: “Climate is what you expect; weather is what you get.” Based on research of the geologic record, we know that climate change has happened throughout Earth's history and at present, ever-increasing evidence points to the roles that humans play in altering Earth systems. The Earth and its atmosphere receive heat energy from the sun; the atmospheric heat budget of the Earth depends on the balance between incoming solar radiation and outgoing radiation from the planet; which has been constant over the last few thousand years. However present evidence seems to suggest that the recent increase in temperature has been brought about by pollution of the atmosphere, in particular the release of huge amounts of carbon dioxide, mostly through Anthropogenic Forcing (human activity) and other various internal and external factors.
