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.
Climate change is one of the biggest concerns for all nations across the globe over centuries. Climate shift refers to changes in patterns of weather which can be indicated through global warming, natural disasters and rise in sea level. There is a group of people, climate change skeptics, argue that climate change is not the result of human activity, meaning that it is naturally occurred. According to Slaght, this refers to internal factors which are the interaction between the atmosphere and ocean, and external factor, such as solar energy variations and volcanic eruption (John Slaght, 2009). However, most scientist claims that human also involve in this process. Consequently, this essay aims to discuss the impacts of greenhouse gases on climate, and then the contribution of human to climate change and lastly, some statistics about the effects of global warming.
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...
In just the last fifty years, humans, namely Americans have virtually remodeled the Earth and everything on it. We have changed its landscapes, wind patterns, migration routes, and weather; diminished its greenery and killed its animals. Nature did not seem a force that could be controlled and yet it has been. We are conducting an inadvertent global experiment by changing the face of the entire planet. We are destroying the ozone layer, which allows life to exist on the Earth's surface, clearing the majority of the earth’s forests, and disrupting countless ecosystems. The result has been an unfavorable alteration of the composition of the biosphere and the Earth's heat balance. If we do not slow down our use of fossil fuels and stop destroying the forests, the world will become hotter than it has been in the past million years. This warming will rearrange entire biological communities and cause many species to become extinct.
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

For decades scientists have claimed that the Earth is undergoing global warming caused by human activity, primarily the burning of fossil fuel. However, one can look back through history to see that global warming is a natural cycle. The Earth routinely goes through a process of cooling and warming. Approximately, every 100,000 years there is a documented spike in temperature on Earth. Historical data indicates that when this spike occurs there is an increase in CO2 levels.
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
Nowadays, climate change is became a major global issue which are affecting our life such as global warming ,mean sea level changing and more extreme weather events etc .According to the research of Intergovernmental Panel on Climate Change 2007 ,it showed that the global mean temperature rose by 0.74 °C during the hundred year period from 1906 to 2005. Between 1956 and 2005,the rising rate was 0.13°C per decade in this 50 years , nearly twice the rate in the past 100 years. Eight (2010, 2005, 2003, 2007, 2006, 2009, 2012, 2004) of the last ten years (from 2003 to 2012) rank among the 10 warmest years on record. It seems that climate change is potentially affecting our life.In fact,human activities and natural effect are the causes of climate change.Generally,most of the scientists and government agree that human activities is the main causes of climate change rather than natural causes.Therefore,this essay is going to discuss why human activities change the climate more seriously than natural effect.Afterward,I will also present some possible solution to reduce the climate change.
Interactions between human and the ecosystem have been operating for millenniums, and are impossible to eliminate, as each depends on the other in order to survive and flourish. However, as modern technology advances, as well as the increase in the world’s population, the need for natural resources begin to rise to an alarming rate which has started to gradually destroy the ecosystem. Recently, there has been an increase of sea levels in region whilst other rain-bounty areas have begun to experience their first droughts. This phenomenon is known as climate change. Climatologists have concluded that human activity has played a major role in contributing to the changes, therefore requiring extreme measures before this phenomenon evolves into a catastrophe. In this essay, we will discuss human activities that contributed to climate change, as well as addressing possible solutions to the phenomenon.
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.
Some may say this is a natural cycle of the earth, and that some natural factors are emitting CO2 into the atmosphere which causes the atmosphere to keep more heat in. While volcanos put out 315 million tons of Co2 every year, human activity such as motor vehicles, factories, and burning of fossil fuels all create an amount of 30 billion tons of Co2 annually(Climate). Our earth is fragile; consequently, resources are limited(9). To keep our earth from total destruction we as the humans of
In recent years global warming has been on the rise. The importance of this issue is so that we as a nation can be aware of the drastic changes which are occurring rapidly around the world. Although there isn 't one set resolution to solve climate change, we must continue to carry out ways to put it to a halt. Some of the ways I believe we can cut this crisis is to stop polluting the manufacturing of toxic gases which is filling our environment with smog. If we all put our ideas and opinions in ways to prevent some causes of climate change, the world in which we live will be a better place. Instead of being a part of the problem we can be a part of the solution. Opposed to just humans, animals, and other species are affected as a result of
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.
