Global Warming
Lets face it, humans are terrible. We are arguably the worst thing that has ever happened to this planet. It would probably be better off without us. We have had a devastating effect on our planet’s ecosystem. Climate change is happening, and many say that we are responsible for it. Google defines climate change as “a change in global or regional climate patterns”, in particular change brought on by increasingly high levels of carbon dioxide in our atmosphere. High levels of carbon dioxide, and other greenhouse gases, stop the suns rays from being able to leave our atmosphere and thus, warm our planet. This is why this epidemic has earned the quite literal name of “global warming”. For the past few hundred thousand years the amount of greenhouse gases in the earth’s atmosphere have been at natural and comfortable life sustaining levels. But in just the last one hundred or so years, since the beginning of the industrial revolution, the levels of greenhouse gases, in particular carbon dioxide, have gone through the roof. Global warming can, and will, if not stopped, have devastating effects on our planet; possibilities include rising temperatures, droughts, mass extinctions and much more. Humans are having a strong, negative, impact on the environment.
The “greenhouse effect” is the most prominent cause for the rise of global temperatures. According to the book, “Earth’s Changing Environment” the warming of the earth’s climate is due to a collection of gases in the atmosphere. There are various gases in our planets atmosphere, including: water vapor, carbon dioxide, nitrous oxide and methane. These gases, called greenhouse gases, absorb a large portion of the radiation from the sun and send it back to the ear...

...the damage that we have already done, but not impossible. It is very important that we do all we can to stop this global crisis before it gets any worse that it already is or there won't be any chance of success.
In conclusion, humans are having a devastating effect on our environment. Ultimately, we all must agree that climate change is happening and it is very frustrating that some deny it. The evidence shows that global warming is real, and human caused. We are all going to be affected by it and it is in all of our best interests to work together to solve this problem. The upshot of all this is that it is fixable, although we have already dug ourselves into a very deep hole there is still a small chance of getting out of it. This may be our last chance to save our planet. If we all do our part we might just stop global warming before it gets get any worse.
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.
The gradual warming of temperatures doesn’t just effect us though, there are numerous other plants and animals that will be threatened, or even pushed to extinction due to these changes. I believe it is our duty to fix the problem that we created, but it is more easily said than done. Megablazes, droughts, or even species extinction due to human stubbornness is unacceptable. Although climate change is a gradual issue, the factors that contribute to it need to be managed right away. Again, Global warming is caused by UV radiation reflecting between the ozone layer and the earth. The ozone consists of greenhouse gases, carbon dioxide and methane, which humans are the main source of. If we could better manage our carbon dioxide and methane output through less omissions or a carbon tax, I think we could effectively begin to curb the problem of climate
The consequences as the result of the earth warming up cannot be ignored any longer. We need to stop wasting our time debating if climate change is man-made or a natural phenomenon. It is clear to me, and many scientists, that we are slowly killing our planet and all its inhabitants (human and non-human animals). We need to stand united and stand tall in this fight to save the ecosystems. We have become an over populated consumerist society, consuming far more natural resources and energy than the generations before the Industrial Revolution. Thus giving off substantial amounts of greenhouse gases that dramatically change the temperature of our planet. It is well documented in various reports how much the Earth’s temperature is rising and is predicted to rise at a rate of 2°C in the next two to three decades. With two-thirds of the world’s population living within two hundred miles of seacoast, and with most of the world’s economy concentrated in coastal cities, rising sea levels would cause immense devastation. Climate change is happening before our eyes with unpredictable storms and weather patterns, severe droughts, and melting polar caps. It is up to each of us to change our behavior to a more sustainable one, by utilizing renewable energy sources--humankind and the Earth are depending on it (Lovelock
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...
Climate change has been nothing, but controversial in the last fifty years. Climate change is a change in the average weather of a region or city. Scientists have opted to use the term "climate change" instead of global warming because as the Earth's average temperature changes, winds and ocean currents move heat around the globe in ways that can cool some areas, as well as warm others. There is an ongoing dispute about the effects of humans on the global climate and about what policies should be implemented to avoid possible undesirable effects of climate change. Ninety-seven percent of published scientific research concluded that climate change is real, problematic for the planet, and has been exacerbated by human activity. But what about the three percent that contradicts that?
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.
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.
Air pollution and greenhouse gases are the reason for the planet as it is today; the reason why we see campaigns flooding the media informing us to ‘switch off’, ‘save the planet’ and ‘turn down the heat’ and the reason why the government is trying to develop a successful scheme, such as the carbon tax scheme, to reduce air pollution caused by major industries. Air pollution and greenhouse gases are the two immediate causes of global warming and climate change. Air pollution occurs when chemicals or particulate matter enter the atmosphere. They can cause damage to living organisms on the planet, as well as destruction to the natural and synthetic environment (Energy Environment.net 2008). Greenhouse gases are gases in the atmosphere that absorb infrared radiation emitted from the earth. They trap infrared radiation in the form of heat, and hence contribute to global warming. Anthropogenic greenhouse gases are a direct result of air pollution. They are the physical gases emitted that cause air pollution. Naturally occurring greenhouse gases also have an influence on the earth’s atmosphere, though it is not as conspicuous as anthropogenic causes. Together, air pollution and greenhouse gases are intensifying climate change and global warming on a world-wide basis.
Global warming and the greenhouse effect are issues discussed by scientists all the time. A natural process that keeps earths temperature at a livable rate is called the greenhouse effect. The energy from the sun warms up the earth when the rays from the sun are absorbed by greenhouse gases. The gasses then become trapped in the atmosphere. Carbon dioxide, water vapor, methane and nitrous oxide are the most common greenhouse gases.
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 a condition caused by greenhouse gases and human activities. The increased concentration of greenhouse gases due to activities such as deforestation and fossil fuel burning is causing the Earth’s atmosphere and oceans to warm up. As a result of this, global warming has some serious effects in the shape of extreme weather, species extinctions, and rising sea levels. These effects can contribute to the changes that are taking place all over the world, most of which are dangerous enough to pose a threat to the survival of life on Earth in the future.
Human beings are the advanced species on the earth. The ability of our ancestors to think outside of the box is the reason why humans are the most dominant species. Once upon a time humans were same as the wild animals. The daily chore for human from the past was to hunt, eat, and survive. At present, the life of human beings is more convenient with all the inventions like cars and air conditioners. These inventions have made our lives easier but have also helped to cause global warming. The emission of carbon dioxide from these machines in the atmosphere causes global warming. Global warming, defined by Oxford dictionary is a 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 (“Definition of global….”). There are several creative ideas to stop global warming and some of them have promises, for example, saving money while saving the environment. Planting and protecting the trees is a popular attempt, and it looks great on paper, this solution works well and is beneficial for the people as well as the environment.
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)
Global warming is the gradual rise in temperature and oceans due to recent human activity. This is created by the production of too much carbon dioxide that is released into the earth’s atmosphere. 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 for some greenhouse gases can be in the atmosphere for a short amount of time, other gases can remain in the atmosphere for thousands of
