The Greenland ice sheet, climate change and human activity.
Genesis 1:26 – And God said, “let us make man in our image, after our likeness: and let them have dominion over the fish in the sea and over the birds in the sky and over the livestock and all the wild animals and over all the creatures that move along the ground”.
However you come to believe the origins of humanity it is clear that as a species we hold dominion over all the world. No other species, individually or collectively has more influence on planet earth. There are taller, bigger, stronger forms of life. And in terms of bio mass there are forms of life that are more numerous but none can claim domonion except human kind.
Dominion in simple terms is the right to use and responsibility

Decreased water quality, increased pollution and depletion of natural resources are direct results but there are secondary effects that are a part of a series of actions and reactions(seatlepi.com). The impact of human activity can most easily be observed through our water and one of the biggest impacts on water is excess nutrient inputs from the overuse of fertilizers globally and from oil and chemical spills and dumping regionally. The majority of air pollution comes from fossil fuel combustion from vehicles including airplance, factories and power plants.
Much of the confusion and disagreement around anthropogenic climate change is due to words and terminology to define it as well as the ability to quantify the data, however, it is clear that humanity has the ability to influence and change the climate and environment of the earth. On the local level we sit it in the quality of our air, water and food and on the global scale with the mass wasting of ice
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.
26 Then God said, “Let us make mankind in our image, in our likeness, so that they may rule over the fish in the sea and the birds in the sky, over the livestock and all the wild animals, {a} and over all the creatures that move along the ground.” 27 So God created mankind in his
Climate change is a growing issue with the rise in industrial, commercial, and personal usage of energy. The burning of such things such as oil, coal and natural gases create toxic pollutants called “greenhouse gases.” The largest and most prevalent of greenhouse gases is carbon dioxide. (Overview of Greenhouse Gases). The wasteful history humanity has exhibited is deadly to the progression of our Earth. There are many things humanity can do in order to delay the inevitable warming of our planet and to prevent human-generated effects. Knowledge on the subject can significantly increase the awareness and subsequently improve the outcome of a global effort put forth by society. All that needs to be done, is to recognize our impact and how we can make a difference.
produced by humans are the cause of climate change. The development of new policies and
Over the last 100 years, global temperatures have warmed by about 1.33 degrees Fahrenheit on average(Pappas). This small change in temperature can and most likely will have long term effects. All forms of life that made the colder regions of the earth their homes are in danger of extinction. As temperatures shift, penguins are shifting their breeding seasons, too. A March 2012 study found that Gentoo penguins are adapting more quickly to warmer weather, because they aren’t as dependent on sea ice for breeding as other species(Pappas). Decreased winter snowfall on mountaintops is allowing elk in northern Arizona to forage at higher elevations all winter, contributing to a decline in seasonal plants. Elk have ravaged trees such as maples and aspens, which in turn has led
Warmer, sea ice-free oceans could also increase melting from Greenland's glaciers. The quicker sea ice loss causes Arctic temperatures to rise, the faster the Greenland ice sheet is likely to melt and while it isn't going to disappear any time soon, this contributes more to sea level rise. According to Carbon Brief, it states, ¨ temperatures rise faster in the Arctic than at lower latitudes, this changes largescale temperature and pressure gradients which has consequences for northern hemisphere winter weather. The loss of sea ice will also have consequences for people and ecosystems in the Arctic region. Melting sea ice is likely to have global consequences by unlocking new shipping routes and exposing more fossil fuel reserves.¨ 1. The melting of the ice causes the sea level to rise.
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.
Think of bodies of ice bigger than some countries. Bodies of ice that impacts our daily lives. Such chunks of ice are most are commonly known as the North pole or the South pole. In reality, these great bodies of ice found throughout most of the planet and do more than just provide us a cold breeze. They have been contributing in drastic things such as global warming, the water we drink, and many agricultural influences around the globe. As time has passed, naturally, with gas emissions, pollution and global warming has caused the Earth to warm. In exchange, ice caps are melting more and more, and yet as more time passes we will soon see the drastic effects of the disappearance of ice caps. These chunks of ice continue to grow
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.
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 ...

Mankind’s origin was premeditated from God, formed from the dust of the earth, and made in His image and likeness. God confers with Himself and rouses Himself to make man in His own image and likeness (Bavinck 1). Because man is made in God’s image and likeness, he is set apart from any other creature or angel ever created. Man has a relationship with God that no other creature will ever have.
Humans were created in God’s image. Because God is perfect and without error (infallible), we are a reflection of that. However, when Adam and Eve sinned against god, that infallibility was tainted....
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...
