The End Of Nature By Bill Mckibbin

740 Words3 Pages

CHAPTER 1
INTRODUCTION
The Global Warming is the increase of Earth's average surface temperature due to effect of greenhouse gases, such as C02 emissions from burning fossil fuels or from deforestation, which trap the heat that would otherwise escape from Earth. This is a type of greenhouse effect. Figure1.global warming representation
Is global warming, caused by human activity, even remotely Possible?
Earth's climate is mostly influenced by first 6 miles or so of the atmosphere which contains most of the matter making up the atmosphere. This is really a very very thin layer, if you think about it. In the book The End of Nature, author Bill McKibbin tells of walking three miles to from his cabin in the Adirondack's to buy food. Afterwards, …show more content…

However, even slight increases in atmospheric levels of (CO2) can cause a substantial increase in temperature.
 The Flactuation in temperature is also also a cause for global warming or green house effect…
 About 2/3rd of the centuries warming has taken place in the last 25 years: 1990s were the warmest decade of the 20th century.

CAUSES…
 Oxygen(O2) and nitrogen lack the internal vibrational modes that molecules with more than two atoms have, Both water and CO2, for examples, save these "internal vibrational modes", and these vibrational modes can absorb and reradiate infrared radiation, which causes the greenhouse …show more content…

How much have we increased the Atmosphere's CO2 Concentration?
1.2. Human beings have increased the CO2 concentration in the atmosphere by about thirty percent, which is an extremely significant increase.
Figure1.3 graph showing co2 concentration

It is believed that human beings are responsible for this because the increase is almost perfectly correlated with increases in fossil fuel combustion, and also due other evidence, such as changes in the ratios of different carbon isotopes in atmospheric CO2.
Combustion of Fossil Fuels, for electricity generation, transportation, and heating, and also the manufacture of cement, all result in the total worldwide emission of about 22 billion tons of carbon dioxide to the atmosphere each year. About a third of this comes from electricity generation, and another third from transportation, and a third from all other sources.
This enormous input of CO2 is causing the atmospheric levels of CO2 to rise dramatically.. Figure1.4 showing lattest report on rise of

Changes occurring in the sun itself can affect the climate change on Earth. The intensity of the sunlight reaching the Earth can cause either warming or cooling. The sun flows a natural 11 year cycle of small ups and downs in intensity, but the effect of it on the Earth’s climate is negligible. However, over the past years, the sun’s intensity has been lower than the mid 20th century, and therefore does not explain the recent warming of the Earth. • Also

Bill Mckibben's The End Of Nature

181 Words | 1 Pages

In Bill McKibben’s novel, “The End of Nature”, the main argument that McKibben is making is everything that humans touch, they destroy. He explains how the pristine natural world was one untouched by humans, but now everything reflects humans. McKibben laments the loss of the idea of wilderness, or untouched nature. Increasingly, everything in the natural world is in some way altered by human use. Along with the loss of the last remnants of natural environment, McKibben suggests, we are losing our idea of nature, so that we can no longer appreciate the value of an unspoiled natural environment.

Why Earth's Temperature Is Directly Affected By The Amount Of Greenhouse Gases In The Atmosphere.

453 Words | 2 Pages

Increases in the amount of carbon dioxide and other greenhouse gases in the Earth's atmosphere have caused an enhanced greenhouse effect. With emissions being produced daily, a large imbalance is being created which is enhancing the greenhouse effect and making it stronger. As there are naturally occurring greenhouse gases in the atmosphere that help keep the Earth warm, additional amounts of these gases leads to more heat being trapped on the planet. This extra heat is causing global warming as well as affecting the Earth's weather patterns. Define global warming and explain what has caused the recent trend of warming that the earth is experiencing.

Many other theories of climate change were advanced, involving forces from volcanism to solar variation. In the 1960s, the global warming effect of carbon dioxide gas became increasingly convincing. Scientist pointed out that human activities such as; atmospheric aerosols (pollution) is having cooling effects. (Wikipedia, 2015) This essay, which began with the definition of climate change and the history of how climate change was discovered in the 19th century.

An Overview of Climate Change Climate change can be defined as the fluctuation in long-term weather patterns (DS Foundation). One form of climate change is global warming, which is the progressive warming of the planet (Habitable Planet). Since the industrial revolution, the average global temperature has increased by approximately 0.8o celsius (Habitable Planet, McKibben, 2012). These long-term changes are attributed to anthropogenic sources such as fossil fuel combustion for industrial activities (Habitable Planet). Fossil fuel combustion (among other forms of emissions) result in increased concentrations of atmospheric greenhouse gasses (Habitable Planet).

“66.4% of the studies had no stated position on anthropogenic global warming, and while 32.6% of the studies implied or stated that humans are contributing to climate change, only 65 papers (0.5%) explicitly stated "that humans are the primary cause of recent global warming.” (“Popular Technology, "1350+ Peer-Reviewed Papers Supporting Skeptic Arguments against ACC/AGW Alarmism,” populartechnology.net, Feb. 12, 2014.) 32.6% of humans are only contributing to the global air, but natural resources such as lightning strikes which cause wildfires can affect the global air, and etc. This means human activities are not really causing that much of an effect to global warming, but the world 's natural resources

An Essay: Why Climate Change Is Not Real?

708 Words | 3 Pages

Climate change is refers to the rise in average surface temperatures on earth, mostly due to the burning of the fossil fuels such as oil and coal, which emits greenhouse gases into the atmosphere which are primarily carbon dioxide, water vapor, methane, nitrous oxide, and chlorofluorocarbons (#02). In addition, other human activities, such as agriculture and deforestation, also contribute to the growth of greenhouse gases that cause climate change (#01). According to this, many have make their own conclusions on how are humans responsible for climate change and whether or not it is a real thing. Some people think and guarantee that climate change is real and it is happening at least in part because of human activity.

The Pros And Cons Of Climate Change

1524 Words | 7 Pages

Climate Change: The Facts, the Effects, and the Arguments Before humans and before human's were industrial enough to cause a significant impact on earth's climate, climate change was caused by many natural factors including changes in natural greenhouse gas concentrations. The natural "greenhouse effect" is caused by heat-trapping gases. These gases absorb heat that is radiated from the earth's surface and then radiates the energy back to the surface. Our climate is dependent on this warming effect, without which the earth would be about 60 degrees Fahrenheit colder (U.S Global 14). Without this warming effect we would not able to live, nor would we be here to begin with.

Carbon Dioxide (CO2) is the gas of the highest percentage in the atmosphere, which is found to be 82% in the atmosphere. There are 4 main sources from which it’s emitted. Firstly, CO2 is naturally found in the atmosphere as a part of the carbon cycle; which is the natural circulation of carbon among the atmosphere, oceans, plants, soil and animals. The human practices cause alterations in the carbon cycle. Nowadays, as a part of the human activities, CO2 is produced in large amounts due to the industrial activities.
