Fossil Fuels And Climate Change Essay

Fossil Fuels and Climate Change Essay
In this paper, we focus on using fossil fuels causing climate change. Fossil fuels are fuels formed natural resources such as coal, petroleum and natural
gas, which are the most widely used fuel and industrial chemicals in the world. Since industrial revolution, fossil fuels bring a very great quantity
convenience and technological products. So we can use cars, planes and all modern products. But fossil fuels cause climate change at the same time.
Greenhouse gas, nitrous oxides and a great deal of harmful gas which are from fossil fuels are causing serious environmental problems. Therefore we
need to be concerned about the problems caused by fossil fuels and the solutions. From human entered industrial civilization era. Our human beings

Some nitrous oxides sulfur oxides lead to acid rain. It can have harmful effects on plants, animals and buildings. Oil spill in Gulf of Mexico this year
caused ecological disaster. "An explosion occurred on the semi–submersible offshore drilling rig Deepwater Horizon in the Gulf of Mexico, killing 11
rig workers and injuring 17 others. On April 24, it was found that the wellhead was damaged and was leaking oil into the Gulf. This significant
spill poses a serious threat to wildlife, affecting as many as 400 species along the coastal areas of Louisiana, Mississippi, Alabama, and Florida."
(Curry L. Hagerty, 2010) The number of fossil fuels is limited. Even they are enough now. Are they still enough in 50 years? So it is a time for our
human beings to decide how to deal with the relationship with fossil fuels. When I am writing this essay, Jiangsu province is suffering from the most
serious drought from last 50 years. Suzhou, a city should have been rainy. But I almost have not seen rain since I come to Suzhou. "Climate changes
caused by human activities, most importantly the burning of fossil fuels (coal, oil, and natural gas) and deforestation, are superimposed on, and to some
extent masked by, natural fluctuations."(Hamburg, S. et al, 1997) Due to these violent human activities, those kinds of extreme phenomena are
becoming much more popular than before. Human burning countless fossil fuels recklessly lead to too

Fossil Tiktasalik Essay
The author and his colleagues chose to focus on 375 million year old rocks in their search for fossils because amphibians that look dissimilar to
fish were discovered in 365 million year old rocks, while fish without amphibian characteristics were discovered in 385 million year old rocks.
Thus, it is possible that the evolutionary intermediary, or the "missing link" between fish and amphibians, would be discovered in 375 million year
old rocks, between the two time periods. The rocks examined were sedimentary in composition, as the gradual and relatively gentle formation of
sedimentary rock under conditions of mild pressure and low heat are conducive to the fossilization of animal remains. Sedimentary rock is also
often formed in rivers and seas, where animals are likely to live. This site provides a resource that describes means by which fossils are formed and
how the fossil record may be interpreted, and shows some examples of fossils demonstrating evolution through geological periods: http:/
/www.fossilmuseum.net/fossilrecord.htm. In 2004, Shubin and his colleagues were looking for fossils on Ellesmere Island, in northern Canada. This
location was chosen because of its lack of human development, as well as of obstructing natural formations and life forms such as trees, which...show

Describe the fossil Tiktaalik. Why does this fossil confirm a major prediction of paleontology?
The fossil of Tiktaalik confirmed a major prediction of paleontology in that it showed characteristics of both aquatic animals, such as fish, and land
animals, such as reptiles and amphibians. While it had fins and scales, it also had a flexible neck, a flat head, and complex bone structure in its fins that
correspond with the structure of the legs of terrestrial animals. Thus, it demonstrates the evolutionary transition between aquatic and terrestrial life.
Explain why Neil Shubin thinks Tiktaalik says something about our own bodies? (in other words – why the Inner Fish title for the

Fossil Fuels
Energy, whether it was sunlight or heat from a wood fire, has always been important to society. However, with the onset of the industrial revolution
over 200 years ago, wood alone could no longer support the increasing energy demand. The world quickly turned to coal to satisfy its energy needs,
and it has been reliant on fossil fuels ever since. Despite the inroads renewable and nuclear energies have made in recent decades, the vast majority of
energy used by society still comes from the three main fossil fuels: petroleum, natural gas, and coal. As a result, it is important to know how these fuels
were formed, the rates at which they are produced and consumed, and how much is economically recoverable for future use....show more content...
However, when temperatures exceed 160ВўВЄC, all of the oil in the sources rock burns off to form natural gas. So source rock that is exposed to
these high temperatures accounts for the formation of natural gas wells in which there is no oil.
The source rock is often times buried beneath a layer of porous sedimentary rock. The pores in this rock are filled with water, so it is called the
reservoir rock. Since oil and gas float on water, the hydrocarbons in the source rock rise through the reservoir rock. They continued to rise until they
encountered an impermeable layer of rock, where they stop and form a reserve. The natural gas, since it is lighter, will always rest on top of any oil in
the reserve(Marshak 433–4).
Oil has become the most widely used energy source in the world. This is because oil is both easy to transport and flexible in its uses, unlike natural
gas, which is costly to transport, and coal, which currently has limited applications. The result is that thirty–eight percent of energy used in the United
States comes from the burning of oil(Ristinen 17). Transportation, which gets almost ninety–eight percent of its energy from oil, accounts for most of
the oil use in the US(Ristinen 20). This is due to the fact that the price of oil in the US does not reflect its true cost. With the combination of high
subsidies and low taxes on oil, the US government has produced a market in which gasoline is cheap and abundant. When compared to other

Fossil Fuels Vs. Renewable Energy Essay
Abstract – The world can't be imagined without IC Engines ,as their applications are wider in various fields. And mainly used input for this engines
are fossil fuels. But the challenge in this is decreasing rate of resources. The fossil fuels may not be available after some years if they used in the
same way .Not only the fossil but also the electric power is the non renewable energy, This paper concentrates to run the engine without fossil fuels or
electricity.
Keywords – IC Engines, fossil fuels , non renewable energy
I.INTRODUCTION
In today's motorized life , It's difficult to live without motor (Engines) and the main source of it's input power is fossil fuels & partly electric
power. In future these fuels or electricity may not be available widely as they are non renewable energies. So, it may be difficult to use engine with
the fuels. Not only the problem of lack of resources but also but also they pollutes the environment. If the fossil fuels are used in this way for some
more years ,It may difficult to breath in the future and many things which are harmful to the earth may happen like global warming .this may leads in
danger to the lives of creatures. To solve this problems compressed air technology (CAT) was invented, and again the problem in this is input power.
The air may be freely available in the atmosphere , but it needs to be compressed to use and the power it needs for compression is electrical energy ,
which is also a non– renewable energy.

Persuasive Essay On Fossil Fuels
According to the World Bank Data, 93% of the world's energy resources is supplied by fossil fuels.
One of the problems is that fossil fuels are non–renewable. They are limited in supply and will one day be depleted.
Fossil fuels are formed from plants and animals that lived hundreds of million of years ago died and were gradually buried by layers of rock.
Fossil fuels are coal, oil, and natural gas. Oil powers most of the transportation sector. Coal and natural gas power most of our electricity. At the rate of
our consumption, these fuels cannot occur fast enough to meet our current of future energy demands.
Now, in the first couple decades of the 21st century, in order to sustain our dependence on fossil fuels we're going to very risky, very extreme new
sources. You see this, in things like mountain top removal for coal, fracking for natural gas, offshore drilling for oil, and the tar sands, which is the
most devastating form of producing fossil fuels. They take away massive forests, the water in the streams, and rivers is poisoned. It has severe impacts
on the wildlife, on native communities, and it requires a huge amount of energy to simply get it to our fuel tanks.
All our modes of transportation, boats, trains, planes, cars, the way we produce our food, the way we build our cities, almost everything we do releases
carbon dioxide and that leads to climate change. The polar ice caps will melt, the seas will start to rise, there will be more dangerous weather

Fossil Fuels And Global Warming
Sustainable Energy
The world right now is facing a major disaster if our habits don't change. Fossil fuels dominate our energy demand and at our current rate this will
remain true for quite some time. The World Energy outlook claims that by 2030 84% of our energy demands will be fulfilled by fossil fuels (Shafiee et
al, 181). It is believed that we possess the reserves to meet our demands until 2030 (Shafiee et al, 181) but the cost will increase as time goes on. Fossil
fuels are a non–renewable resource, meaning that once we run out of what's currently available, we cannot replenish it. Our future energy needs are
heavily dependent on a non–renewable and quickly depleting energy source.
The issue of fossil fuels running out is only one...show more content...
2 degrees may not sound like a huge temperature change but it is enough to completely change ecosystems and rapidly melt glaciers and snow fall on
mountains such as Mount Hood.
In Portland many efforts are being taken to reduce our dependence on fossil fuels. One of the most common forms of renewable energy currently is
solar. There are many companies in Portland that sell solar solutions such as Solar Oregon and Sun Run. Portland General Electric also offers
programs like Green Future Solar and Green Source, which allow you to only purchase energy produced by renewables. The energy provided by the
green source plan is a majority of wind power, with a small percentage being provided by solar and geothermal. PGE has had a great response to
these plans and according to the US Department of Energy they are number 1 in renewable energy sold among power companies in the US. There are
also a claimed 17,000 households in Oregon that have solar energy systems. The push to purchase these plans and install solar panels on homes and
businesses is leading to a decreased reliance on traditional power plants, which rely heavily on fossil fuels and coal to provide the necessary energy. A
reduced usage of these fuels leads to a less dramatic warming effect and a much smaller carbon footprint.
These programs have been effective, but a stronger push to use renewables is still needed. The costs of

Fossils Research Paper
: Fossils are the remains or traces of ancient organisms which have been preserved. For example, a fossil can exist as skeletal remains or even as a
footprint. Such organisms are subjected to a slow rate of decaying since they have been rapidly buried under conditions that facilitate this. It is
common for fossils to occur as hard–bodied organisms as these are more resistant to environmental influences. Fossils are usually found embedded in
rock. The layers of rock are of different age and makeup. Hence fossils found in one layer would vary in characteristics from those found in another
layer. They can be observed and analyzed through visual as well as radiometric means so that the age and morphology can be determined. These
features indicate

Why Fossils Is Important
Fossils are considered essential for the study of biological evolution because a lot of the time they conserve tissue, which allows scientists to find out
numerous things about an organism. Even though fossils do not contain the original biological material, these tissues aid scientists in figuring out the
genetic make–up of an organism.This is important because it can lead to help scientists better understand the evolution of organisms and what caused
the changes in the first place.
Many things can be learned from studying fossils. Studying fossils can tell us anything from where an organism may have lived and how long ago an
organism lived. Also, scientists can even learn what an organism consumed while it was alive if there are coprolites

Essay on Environmental Impact of Fossil Fuels
Environmental Impact of Fossil Fuels
Fossil fuels cause pollution, smog, and the greenhouse effect. Fossil fuels really do negatively impact our environment, especially when it comes to
global warming,
Although there is controversy over whether or not fossil fuels are causing the planet to warm, or whether it is warming naturally, there is significant
research that supports the former hypothesis. When fossil fuels are burned, they emit different levels of carbon dioxide. The burning of fossil fuels has
increased the amount of carbon dioxide in the atmosphere by a staggering twenty– five percent. It has also been implied that fossil fuels are associated
with increased levels of nitrous oxide and methane,...show more content...
Fingerprints are "direct manifestations of a widespread and long–term trend toward warmer global temperatures" (Global Warming). The Harbingers
category included effects such as spreading disease, differing populations of plants and animals, coral bleaching and droughts and fires among others.
The Fingerprints category included things such as heat waves, glacial melting, and rising sea levels (Global Warming). This map enabled me to see the
effects that global warming would have on me personally, and the country as a whole, as well as continents all over the world.
Although an obvious solution to the problem of global warming would be to stop using fossil fuels, that would cause significant damage to the
economy of the United States as well as many other countries that rely on fossil fuels heavily for industry and transportation. According to the
National Resources Defense Council, people can take many steps to reduce the effects of fossil fuels on the environment. Some of these steps include
buying a car that gets good gas mileage, only driving when necessary, carpooling and buying energy–efficient appliances. Replacing light bulbs with
compact fluorescent light bulbs, and weather–proofing homes and apartments can also help (NRDC).
A single person can greatly affect the effects fossil fuels have on our climate. By obtaining knowledge about the effects of fossil fuels on our
environment, and more specifically global

Should Renewable Energy Sources Replace Fossil Fuels?
Polar bears are the most known animals for the impacts of climate change on species. Global warming has been most prominent in the Arctic, and this
trend is expected to continue. Their dependence on sea ice makes them highly vulnerable to a changing climate. Polar bears greatly rely on the sea ice
environment for traveling, hunting, mating, resting, and in some areas, maternal dens (WWF). Specifically, they depend heavily on sea ice–dependent
prey such as seals. Additionally, their long generation time and low reproductive rate may limit their ability to adapt to changes in the environment.
Every time people breathe or burn something, oxygen in the air is converted to carbon dioxide. The carbon dioxide is used by plants to breathe and
is converted back to oxygen, creating a cycle. If there is an increase in oxygen burning, for example, burning a lot of coal or oil to generate electricity or
run cars, and cut down trees, the amount of carbon dioxide in the air is increased. This makes the air thicker and warms up the earth. The amount of
warming is only a few degrees but it is enough to disturb the fragile balance of nature, which in turn will melt the polar ice, raise sea levels, cause
violent hurricanes and endanger species such as polar bears. The polar bears are just one example of endangered animals because of the high demand
of human need for energy which is acquired by burning fossil fuels.

Fossil Analysis Paper
Fossil Analysis Paper
Locomotion
The skeletal characteristics of these hominines suggest that their mode of locomotion was likely a cross between occasional bipedalism and obligate
bipedalism. From the reading we have learned that obligate bipedalism is bipedal locomotion that is practiced all of the time while occasional
bipedalism is bipedalism that is practiced on occasion. The ratio of arm length to leg length (longer arms) suggests that they did spend time climbing
trees, however the cranial and post cranial traits of these fossils suggest that they spent much of their time on the ground and likely ambulating
bipedally combined with a variation of upright walking and knuckle walking. This is evidenced by two factors: the fact the foramen magnum of the
skull is centrally located, and the ratio of arm to leg length. In creatures with bipedal ambulation, the foramen magnum is located in the center of the
base of the skull to keep the head aligned over the center of gravity of the creature. If the fossils were walking primarily with their knuckles, the...show

Oldowan tools are a very rudimentary form of a stone tool in which it is formed simply by smashing two rocks together until the rock splinters. If
the splinter becomes sharp, it can be used as a tool for cutting. These tools were likely used for scavenging and cutting meat from animals that were
previously killed by another predator. An individual would either use the oldowan tool to scrape and cut meat from a bone, or smash the cranial
and long bones to obtain brain matter or bone marrow. The bones of local fauna show a parallel scrape marks that indicate tool use. Under a
microscope, one can see the patterns created by these tools. If the marks were in a "V" shape, it would indicate a scrape pattern consistent with the
bite of a carnivore. Because of the parallel scrape marks; we can deduce that tools made the

What Is Fossil Evidence?
Fossil Evidence
Fossil evidence is a great way to analyse the effects of evolution. The first statement posed by somebody when a person trying to prove a point is:
prove it. Fossil evidence does just that by providing proof in the forms of preserved life–forms which previously inhabited the earth. The stratigraphic
column is a layering of sedimentary rocks which contain fossils in them (McMullen et al., 2014). The erosion of these rocks carves through this
layering to provide a timeline of fossils. The theory of superposition goes hand in hand with the geological column, this is seen in Bighorn Basin in
Wyoming, U.S.A., where the more anatomically complex and younger fossils, such as tetrapods and vertebrates, appear at the top of the geological

The unzipping of the internal "instructions" which code for body function was discovered and the marvellous molecule of DNA and the genetic
code was discovered for the first time in the 1900's (Pray, 2008). Genetic sequencing is the method by which the building blocks of DNA, nucleotide
base pairs, are ordered to create a gene instruction (Olsvik et al. 1993). These gene sequences can be used in comparison between different species to
link any common genetic traits (Hedges & Kumar, 2002). In Hedges and Kumar article about vertebrate genomes it was found that Homo sapiens,
Human beings, had a similar genome size compared to Pan troglodytes, the common chimpanzee. It was also found that because these animals were
phylogenetically similar, there genomes were roughly the same size, but when compared to the genome sizes for more simpler anatomic animals such
as Gallus gallus, the domestic fowl or chicken, or the Tetraodon nigrovirdis, spotted green pufferfish, there was a huge difference in genomic sizes with
the chicken and pufferfish having substantially smaller genomic size (Hedges & Kumar, 2002). This again shows the evolution of genome size evolution
in combination with the evolution of more complex anatomical structures. Molecular biology can be used in other ways such as tracking and comparing
differences and similarities in protein structures in microstructures such as vessels or bone fragments. An example

Fossil Fuel : Fossil Fuels Essay
Fossil fuels play a huge part in our nations backup power. While clean energy is becoming popular for main energy, fossil fuels are relied on for
backup energy for industry and commercial buildings. Different types of fossil fuels have been used throughout history. Coal and its byproduct has
been used to fuel and improve industry. While green energy is becoming the newest and cleanest form of energy, the transition between the two will
have be dependent on fossil fuels. Fossil fuels play an important role in emergency energy.
In industry and commercial business, power is crucial to function. From simple things like time clocks, to equipment, power is needed for production.
Even after the transition from fossil fuels to clean renewable energy we may still rely on fossil fuels as a last resort. We are already seeing the
automotive industry beginning the transition, yet still relying on fossil fuels. Cars today are being made to use generated electricity to power an
automobile. When that electricity becomes low, whether it is from long distance driving or a problem with the system thefossil fuel backup kicks in to
power the car. In our advancement between the two energy's, this thought process could be used with industrial and commercial buildings. A hospital
is a building that needs to be powered 24 hours a day 7 days a week. Without power their capabilities would be severely limited and could be
catastrophic. We can look at other buildings that rely on power to

Environmental Impacts of Fossil Fuel Use Essay
Environmental Impacts of Fossil Fuel Use
One of the main issues involved with fossil fuels are the environmental impacts that occur from their use. These problems; such as acid rain, oil spills,
climate change, global warming, etc., are not only occurring with fossil fuel usage, but are also increasing due to the increase in the use of fossil fuels.
This essay will vaguely explain the area of environmental impacts from fossil fuel use, and will attempt to change, or further increase your
understanding of the very serious environmental impacts that occur from fossil fuel use.
One of the biggest environmental impacts which is steadily increasing in severity due to fossil fuel usage is global warming. Global warming is
mainly caused due...show more content...
Another environmental impact in which fossil fuel usage contributes to is air pollution; acid rain, smog, etc. Burning fossil fuels increase the amount
of many chemicals in the atmosphere, including nitrogen oxides and sulfur oxides, which eventually lead to increased amounts of acid rain. Acid rain
can destroy the leaves of plants, poison soil and waterways, and ultimately kill many animals and plants (Outdoor Air Pollution). On a more of a human
impact level, air pollution caused by the burning of fossil fuels can eventually lead to things such as lung disease and cancer (Air Pollution). Another
effect that takes place is smog formation. Smog is a problem in many city areas and contributes to low visibility and "dirty skies."
Along with all of these atmosphere and air pollution problems, there are also areas of pollution in which land or water is being polluted due to
fossil fuel use. One of the biggest areas in which land or water pollution takes place is transportation of these fossil fuels. Oil spills are an example
of devastating impacts in which the waterway in which the spill takes place gets polluted, the waterways into which the spill can travel to, as well
as all the shores where the oil polluted water is traveling. On the topic of coal, coal mining can leave by a lot of pyrite, a sulfur compound, which can
be washed away into streams and rivers in the form of an acid as water flows through the mine (Clean Energy). These land and water problems

Understanding Fossils Essay
Understanding fossils can provide insight into so much more than what lived millions of years ago. From my reading there seem to be 4 major
categories that fossils can help us with. Fossils and fossilization, fossils and living organisms, fossils and evolution, fossils and stratigraphy.
Understanding fossils helps us understand life and the conditions that supported life millions of years ago. There are two different types of fossils.
Body fossils and trace fossils. Body fossils are actual remains of plants and animals while trace fossils are they evidence they existed, things like there
tracks, burrows, etc. When these fossils are used together they help scientist learn about a mode of life. Understanding how fossils are formed also helps

Fossil Evidence Of Evolution
1) What are the three lines of fossil evidence that point to an early origin of life on Earth? Discuss each line and what it tells us about when life arose.
What are the implications of an early origin for the possibility of life elsewhere?
The first line of fossil evidence is from stromatolites, layers of early life fossil remains that tell scientists that microorganisms existed billions of years
ago . The second line is microfossils, individual fossilized cells that show evidence that these microbes used sulfur for energy and nutrients. Isotopic
evidence is the third line where carbon dating is used, more specifically carbon–13 since nonliving organisms are found to have a higher level of
carbon–13. This evidence implicates that life is...show more content...
Evidence is found in the K–T sediment layer because there are high amounts of iridium in them, an element rare to find on Earth. This leads to the
theory that it is from an asteroid that made a huge impact, crashing down. More clues to support this claim is the high abundance of metals like
osmium, gold, and platinum, quartz crystals indicating high–temperature and high–pressure stress on them, spherical rock "droplets" from molten rock
that has cooled and become solid in air, and soot. Extreme volcanism, mutations and radiation are possible causes for extinction.
19) When did hominids arise, and when did modern humans

Why Study Fossils
Fossils are literally remains of the past. Things that are fossilized were living beings in the distant past, and the more they are observed the more they
reveal about the time and place they lived in. It is essential to study fossils in order to get an even better grasp at the concept of evolution. Studying
old fossils, especially skeletons, can help us learn about their biology. Their bone structure, such as how their jaws are structured, how long their arms
are, and etc can help reveal if they are relatives of humans or not. Depending on how a fossilized skeleton looks, we can guess what time period the
skeleton came from.
Where a fossil is found is also very important. It gives us an idea of what species lived in that area. The environment

Misconceptions: What Are Fossils?
There are a lot of misconceptions while talking about fossils. Fossils are not limited to the remains of a once living thing, but rather the evidence
of life that existed in the past. This means that a fossil can be a dinosaur footprint, the form of a body on dry mud, bones, etc. We call the
formation of fossils "fossilisation". Fossils form in a really unique way, and it depends on several factors. It is quite hard to have all the favorable
conditions to form a fossil. The corpse of the dead animal is usually eaten, or it is even affected by the presence of bacteria before the process of
fossilisation can start. Erosion and corrosion are also responsible for destroying harder parts of the body, such as the bones. In order for the process

Understanding Fossils
Enrichment Lesson 6 For my enrichment submission this week the topic I chose is understanding of fossils. Fossils are evidence of animal and
plant life that has been preserved within the earth. They can be actual parts of an animal or plant, or traces of an animal such as its preserved
footprints or its preserved waste. Fossils are created when an animal or plant dies. Before it decays, it is covered with sediment, which protects it from
the elements. While we easily recognize and identify some fossils, many fossils are animals that no longer exist. We only know about things that are
extinct, like the dinosaurs through fossils. According to Liz Veloz of Demand Media Fossils aren't used only to understand individual organisms.
