Depletion Of The Arctic Poles Ozone Hole Essay

The tundra is by far the coldest type of biome, as it is known for its low temperatures, little precipitation, poor nutrients, and short growing seasons. Occurring primarily near the Arctic within the Northern Hemisphere, the soil may be frozen all year up to a few feet, which allows no tree growth. However, a few animals have adapted to these conditions. These animals include lemmings, hares, oxen, foxes, wolves, and more. Within the tundra biome there are two different types of tundra biomes, arctic tundra and alpine tundra.

Scientists have given numerous warnings that human-caused, or anthropogenic, climate change is not only occurring now, but accelerating more quickly than predicted (Maibach, Myers, and Leiserowitz 295). Global warming contributes to climate change as a result of the release of greenhouse gases into the atmosphere (“Global Warming”). The level of greenhouse gases like carbon dioxide, methane, and nitrous oxide in the atmosphere has increased significantly over the years. Patterns of warming are sufficient to conclude that this increase has coincided with the start of the Industrial Revolution (“Global Warming”). By analyzing carbon dioxide pockets that have been trapped in Antarctic ice, scientists can assuredly confirm the correlation between recent warming

The article primarily appeals to individuals with interest in global warming. The main point that Wood focuses on is the idea of sulfur-aerosol injection, in which sulfur dioxide would be pumped into the sky. However, there are several issues with this concept that he addresses in his article.

Humans have been interacting with the Arctic tundra for centuries now. They have used the land to explore and race, for example, the infamous race between Admunsen and Scott to the South pole. However, the human civilisation on the Arctic tundra have had their implications, both severe and light. Humans have slaughtered whales and seals since very early days, for food as well as commercial and self-profiting purposes. The most recent and paramount problem is global warming and pollution, which is harming the Arctic Tundra far more than the sealing and whaling ever did.

Did you know that with all this talk about global warming, and the disappearing of the ozone layer, the root of the problem is us? Yes, we’re the cause of all those problems. We keep putting something called greenhouse gases into the air. A few greenhouse gases are water vapor, carbon dioxide, and methane. While some climate change is natural, humans need to be careful about greenhouse gases because ecosystems are changing, sea levels are rising, and global average temperature increased by more than 1.3 degrees Fahrenheit over the last century.

The Earth 's atmosphere has changed all through history. Just in the most recent 650,000 years there have been seven cycles of frigid progress and withdraw, with the sudden end of the last ice age around 7,000 years back denoting the start of the present day atmosphere period and of human development. The greater part of these atmosphere changes are credited to little varieties in Earth 's circle that change the measure of sun based vitality our planet gets. Exploratory proof for warming of the atmosphere framework is unequivocal. The present warming pattern is of specific criticalness in light of the fact that the vast majority of it is likely human-impelled and continuing at a rate that is exceptional in the previous 1,300 years. Earth-circling satellites and other mechanical advances have empowered researchers to see the comprehensive view, gathering a wide range of sorts of data about our planet and its atmosphere on a worldwide scale. This group of information, gathered over numerous years, uncovers the signs of an evolving atmosphere. The warmth catching nature of carbon dioxide and different gasses was shown in the mid-nineteenth century. Their capacity to influence the exchange of infrared vitality through the environment is the logical premise of numerous instruments flown by NASA. There is no doubt that expanded levels of nursery gasses must bring about the Earth to warm accordingly. Ice centers drawn from Greenland, Antarctica, and tropical mountain icy masses

Environmental change in the Arctic has been a subject of recent interest within the discourse of global warming, climate change, and indigenous rights; however, scholars have yet to examine the importance of 20th century racial, cultural, and environmental interactions within Northern Canada. Specifically, the Northern areas of Ontario, Quebec, and Manitoba provide interesting and important issues that are critical to current discussions of global warming, climate change, and water rights and quality because of their location to the Hudson Bay and the intertwined environmental experience. Unlike other areas of Northern Canada, areas in Northern Quebec, Manitoba, and Ontario are subject to multiple political systems (i.e. provincial, federal,

One man's trash is another man's treasure as the old adage goes, but what about when one man's trash is another species pandemic. Pollution has been plaguing humans for centuries, and as a result, the accumulation of this garbage has begun to significantly affect populations other than human beings. A striking example of this is found in Arctic Polar bear populations which as of recently are beginning to display some eerie side effects. Most individuals tend not to think about where their trash goes the second it leaves their hands, but it has to go somewhere. This somewhere is often times the ocean where the trash congregates and migrates around the world where it is consumed by the various species which dwell in its depths. The concentration of these toxins builds slowly within the various species that are exposed to it. Consequently, these concentrations increase as one moves up the food web, and at the top of the Arctic food web sits the beloved polar bear which bears the brunt of these ever increasing concentrations expressed through various health complications.

A change to the reflectivity on the surface of the earth; which is called the albedo, affects the amount of

The Arctic Circle runs through the far north of Canada. This is considered the Canadian Arctic. The Arctic Circle is one of the five major circles of latitude that mark maps of the Earth. “The Arctic Circle, incidentally, is an imaginary line located at 66º, 30'N latitude, and as a guide defines the southernmost part of the Arctic. The climate within the Circle is very cold and much of the area is always covered with ice. (World Atlas) Although this is the case, the position of the Arctic Circle is not fixed. It directly depends on the Earth's axial tilt.

Climate change or colloquially known as global warming, now pose a new threat to civilization as the levels of greenhouse gases (GHG) are soaring to new levels. The most significant contributor to greenhouse gasses would be Carbon Dioxide (Co2). The levels of Carbon Dioxide (Co2) gas have risen to levels civilization has not seen before. As such, the effects of these levels are not known to civilization as data gathered from the ice cores drilled in the Antarctica only shows data up to 650,000 years ago. However we can conclude that present CO2 concentrations are higher compared to any time in the last 650,000 years (IPCC 2007). Current carbon dioxide concentrations are hovering around 389 parts per million (ppm) as of September 2011,

The north and south poles also known as the arctic and Antarctic are two isolated regions of the planet located in each hemisphere of the planet. When for some reasons these two regions come to our minds we used to think in two far, isolated, cold, and uninhabited place of the world. It is true the they seem very similar but is actually the opposite. Their weather and topography is not the same, they have different animals, and their populations are quite different.

The fear of global warming has been looming over people, and baffling scientists for decades. Since it was recognised that climate change is becoming accelerated due to human resources, the knowledge around it has been slowly evolving. Fifty years ago, as will be discussed, thinking around the subject was quite different. Even now experts cannot come to a consensus as to what the result of climate change will be. It is observed, at present, that global warming has made a huge impact on the marine ecosystem as the sea temperature and amount of carbon continues to rise. One of the great concerns about global warming is its effect on the cryosphere and polar caps, of which the science will be later explored. In addition, it is predicted that if global warming continues to develop within the next ten years, the world will change drastically for the worse.

The world continuously faces a variety of threats every day, from natural disasters to terrorist, but one threat that society predominately contributes to all on their own, is climate change. There are many feasible explanations for the global threat of climate change. These explanations include but are not limited to, the act of deforestation to the rainforest and other trees, green house gas emissions, and sulfate aerosol, which cause poor air quality.

Alteration of this natural barrier of atmospheric gases can raise or lower the mean global temperature of the Earth”(Greenhouse Gas).
