...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.
The Global Warming Debate encompasses one of the most complex systems in our natural world, the Earth’s atmosphere, so it is very important to understand the basics. In the book, The Science and Politics of Global Climate Change, climate is defined as “The climate of a place, a region, or the Earth as a whole, is the average over time of meteorological conditions that occur there – the average weather” (Dessler & Parson, 2010, p. 7). The source of energy for the Earth’s climate is electromagnetic radiation, more specifically the sun. This means that the sun is the main driver behind the climate, unless something else acts upon it. According to Environmentalists, humans are changing the climate by our actions. The official definition of manmade climate change is given by The United Nations’ report “Framework Commission on Climate Change”, as “change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods” (Bell, 2011, p. 45). According to environmentalists, the main way humans are changing the climate is by the Green House Effect. The Green ...
There are two main human causes of Earth’s global warming and climate change. The first of which being the greenhouse effect. According to Brian Black in the book Global Warming, the greenhouse effect is the tendency of Earth’s atmosphere to admit the Sun’s radiation but partly retain the low-frequency heat radiation (3). Human activity has changed our greenhouse, especially over the course of the last 150 years due to industrialization. By the burning of fossil fuels, such as coal, petroleum, and oil, carbon dioxide is released into our atmosphere, and heat is trapped in. These gases are typically
One of the major issues in today’s society is Global warming. It is one of many kinds of climate that the Earth goes through. The primary cause of global warming is the human expansion of the greenhouse effect. Greenhouse gases keep the earth warm through a process called greenhouse effect. Greenhouse gases like Carbon dioxide trap heat from the atmosphere and maintain the soil warm. Without greenhouse gases, our planet would be too cold. However, people are adding extra greenhouse gases when they’re driving, using electricity, and in a factory. A lot of energy comes from fossil fuels. According to Environmental Protection Agency, the earth’s temperature has increased by 0.8 degree Celsius over the past century. More than half of this grew
..., and industrial revolution have increased greenhouse gasses in the atmosphere. Greenhouse gases are beneficial for the environment, without them humans wouldn't be able to live on earth. The job of greenhouse gases is to allow sunlight to come into the atmosphere, and then absorb infrared radiation to warm up the earth. The four main greenhouse gases are carbon dioxide, methane, water vapor, ozone, and methane. Among all the greenhouse gasses CO2 plays the an important role because it accounts for 80% of total greenhouse gas emission ( Gore, 2006). In Dr. Cowley’s study he noticed that when past radiance of the sun and volcanic activities were put into a computer model to simulate the energy flow from earth and to earth. The computer produced temperature matching those of the climate from a 1000 years ago. But temperature changed completely in the 20th century.
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. I...
Earth faces one of the most important and complicated issues ever faced, which is climate change. Climate change is the long-term change in atmospheric temperatures and climate. Although it has been denied and prolonged the issue now, it has created an even bigger problem and it has to solved and fast. The human impact over all the years of existence has changed the Earth’s climate completely. More severe storms are occurring, higher and lower temperatures than normal are reported, and some of the planet’s nonrenewable resources are slowly disappearing.
While the Earth has historically gone through fluctuating periods of heating then cooling, “[there is over a] 90 percent certainty that emissions from heat-trapping gases due to human activities have caused [the majority] of the observed increase in globally averaged temperatures since the mid-20th century” (Solomon et al., 2007 as cited in Ekwurzel). These emissions are largely due to non-renewable fossil fuels, like oil, coal and gas, that are burned to power vehicles and produce electricity. Carbon is mined from the Earth’s crust, which is the source of fossil fuels. Global warming is the rise in temperature on Earth, caused by the phenomenon known as the greenhouse effect. Radiation from the sun is reflected onto the Earth’s surface; the solar
Many people don’t know how much they contribute to the emissions of green house gasses. The truth is we as people support the burning of fossil fuels almost unknowingly. We use them for everything from daily household supplies to the gases we use to heat our homes and run our cars. The steady rise in the use of these fossil fuels is having an alarming affect on our climate. Global warming will change the Earth in unimaginable ways. With the ever increasing amount of Greenhouse gasses in our atmosphere, glaciers are now melting rapidly causing sea level to rise. The coastal changes will be sure to change our living environment over the next few hundred years.
There is no longer any question that our world climate has changed (King, 2004). Over the last 100 years, "temperatures have risen by about 0.6 degrees Celsius and global sea level has risen by about 20cm" (K...
The main purpose of this text is to explain that the global warming trends that we are hearing so much about these days actually are “part of a natural trend with a cycle that results in elevated climactic temperatures every 1,500 years” (Avery).
The article “an introduction to climate change” describes in detail about the causes of climate change, and its potential effect on earth. According to this article, the global warming is due to the accumulation of carbon dioxide and other pollutants formed from burning fossil fuels that accumulate on earth’s atmosphere so that light rays are reflected back to the earth surface causing the atmospheric air to heat up. In addition, the article also gives some relevant solutions to global warming such as reducing air pollution and use of “clean energy.”
In talking about global warming, we need to learn what causes the greenhouse effect. Rays from the sun are taken up and absorbed by water vapor that is natural in the atmosphere. The United States emits the largest man made greenhouse gases in the world. As Americans we must realize the responsibility to reduce the emissions. (Gore, Albert) Water Vapor is eighty percent of greenhouse warming. The last twenty percent results from other gases that are in very little amounts. A huge absorber of the sun’s heat rays is carbon dioxide. Us as humans release a lot of carbon dioxide. When fossil fuels are burned, they release big amounts of carbon dioxide. Carbon dioxide is on the increase in our atmosphere due to car emissions. Approximately eighty percent of CO2 increases because of man’s use of fossil fuels. When there is more carbon dioxide in our atmosphere the more sun rays are absorbed. In result to this happening this will cause the earth and the earths atmosphere to warm. When the earth is warming, water temperatures will start to get warmer. Oceans and lakes will get warmer in result f...
Global warming changed from a scientific topic to a real life concern in 1988 and is a topic that proposes everlasting environmental issues. Some countries are already seeing the effects that global warming can cause, not only will the temperature increase causing ice caps to melt and many animals becoming extinct but it’s the way global warming is happening that will really impact the environment. This problem mainly started to rise due to the Industrial Revolution. When more and more factories were built gases were released into the atmosphere and the main gas that causes global warming is the ever-growing amounts of carbon dioxide (CO2). As the world becomes more urbanized the more the crisis of Global Warming increases.
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.
