Essay Cold Environments as Fragile Environments

The tundra, which comes from the Finnish word, tunturi, which means treeless, is the coldest terrestrial biome known to biologists (University of California Museum of Paleontology). Located in the northern hemisphere, between 55° and 70° North, the Tundra covers about 20% of Earth’s surface (S). Although tundras can be found in many of the continents, most notably, the Northern Alaska, Canada and Greenland Tundra and the Scandinavian Montane Birch forest and grasslands stand out the most (Gardella). They are all large tourists attractions disply nature’s ability to thrive in the harshest environments. Winters in the tundra have an average temperature of -30° F, due to its high altitude. However, the average temperatures in the tundra during

The tundra is one of the cooldest land biomes on the planet. Due to the high winds and the permafrost there are no trees becuase it dosent allow the growth of deep roots. All the producers and othe need to get adapted to the cold temperatures, little sun and short growing season to stay alive. The tundra is considered a poor enviroment thats low in resources. The dead minerals get recycled by othe decomposers like the slime molds, fungi, and bacteria. Rain increases photosynthesis and decomposition. Air pollution kills lichen in the cold tundra. The warmer climates allow trees to invade the shade out the small tundra plants. And warmer temperatures can increase decompositon, while releasing more CO2 into the air causing mor global

Can the most high-tech, compact, thoroughly monitored development still pose an unacceptable risk to the wilderness? In a situation such as this where the natural environment is at a serious risk and the public and decision makers are in a dispute, we must all turn to trained scientists in order to more precisely determine what is at risk and which outcome will serve all parties the best.

The arctic Tundra is normally around 10 to 29 degrees fahrenheit. Rainfall may vary in different regions of the arctic. Yearly precipitation, including melting snow, is 6 to 10 inches. Soil is formed slowly. The biggest threat to the Tundra is global warming. Many scientists believe global warming caused by greenhouse gases may eliminate Arctic regions, including the tundras there, forever. Another concern is that about one third of the worlds soil-bound carbon is in the tundra permafrost. Cutting greenhouse gas emissions by switching to alternative energy uses is key to protecting Earth's tundra habitats. The Tundra is located at the top of the earth by the North Pole. Switch to alternative energy

The article “Cold warriors,” Gregoire (2008) indicates that climate change leads to environmental issues and melting ice, and the scientists’ researches point out climatic issues in Canada. The author comes up with a point that everyone is responsible for protecting the environment because people around the world are bearing negative effects due to climate degradation. For example, residents in Grise Fiord and Inuit notice a huge differences, the landscape is becoming warmer, softer and unpredictable. Moreover, a greater risk of environmental pollution is caused by climate change. In addition to changes in environment, shrinking glaciers, earlier ice breakup, later freeze-up and less snow caused by warmer temperature bring double-edged effects

In believe we should not drill in Alaska to satisfy our fuel dependencies. As stated in the documentary “We can import minerals but we cannot import wilderness”, drilling begins a tradeoff; in exchange for minerals we get a damaged ecosystem. Some argue that Alaska has an immense supply of resources that would liberate us from foreign oil, however, there is no guarantee of vast quantities of minerals in Alaska, as the U.S. Department of Energy has stated that there is "considerable uncertainty regarding both the size and quality of the oil resources that exist”. Drilling damages the environment while possibly wielding disappointing results. Even if there is a reservoir of natural resources in Alaska it would not be immediately available

Prudhoe Bay and have seen it co-exist with the their natural resources and their way of life(Doc D). The natives trust that the oil company will take care of the land by enforcing strict regulations. The Alaskan government also believes the drilling will benefit their economy as well as their way of life.

At the present rate of global warming most of the frozen portions of the Arctic may disappear by the end of this century.

The Debate Over the Idea of Drilling for Oil in the Arctic National Wildlife Refuge

The polar ice caps are melting at a pace few nations can afford to ignore, which is yielding potentially profitable sources of energy, minerals, and shipping. But debate is building over whether the Arctic can be developed peaceably. In the 21st century, many experts believe that climate change, technological advances, and ever increasing global demand for resources unlock the economic potential of the Polar North. The melting of Arctic sea ice to record lows in recent years has motivated many nations, mainly those with Arctic Ocean coastlines, such as the United States, Canada, Russia, Norway, and Greenland to reassess their engagements and interests in the icy polar reaches. Canada’s

The news media often chose to highlight the views of environmental groups who had originally been opposed to Exxon’s drilling. These groups “traditionally feared oil development and oil tanker traffic in Alaska, and the opposed the trans-Alaska pipeline from the onset” (Birkland, 1998). They would, therefore, typically offer opinions that were most vehemently against Exxon and would make for more interesting news.

Opposition against the formation of these pipelines seem clear when taken note of the complications to which it can cause, like environmental risk, inessential expenditures, and the ruination of ancestral lands. “In 2010, an Enbridge Energy pipeline dumped more than 843,000 gallons of oil into the Kalamazoo River in Michigan, resulting in a cleanup that lasted years and cost more than a billion dollars,” which incites the thought that these disasters and accidents can disrupt economic stability more than it would assist, given the gamble of safety is lost. The circumstance isn’t worthy of such an insecurity. Oil spills are already an economic destitution and environmental hazard worldwide, there is no need to add on to it with such an uncertain

"Climate change is a change in the statistical properties of the climate system that persists for several decades or longer" (Montgomery, 2015). Climate change (or global warming) can be caused by a natural progress such as sun 's radiations and volcanoes, or it can be caused by human 's actions such as land use, deforestation, and pollution. (Hardy, 2003).This phenomenon not only affects the environment, but it also affects human lives. Alaska is the largest state in the United States. It includes lands on both sides of the Arctic Circle. Sixteen national wildlife refuges are home to a great variety of flora and fauna. In the past 60 years. The Alaska 's environment changed drastically; the climate is warming up as twice as much in comparison to all the other states. This essay will discuss firstly the climate change in the Alaskan environment. Then it will highlight the changes in the ocean and costs, the effects that global warming is having on Alaska 's natives and the melting permafrost. It will then finally address who is responsible for this effects and some measures that can be taken.

The Arctic is global warming’s canary in the coal mine. It is a highly sensitive area which is profoundly affected by the changing climate. The average temperature in the Arctic is rising twice as fast as elsewhere in the world (nrdc.org). Because of this, the ice cap is getting thinner, melting away, and rupturing. Here is an example of this; the largest ice block in the Arctic, the Ward Hunt Ice Shelf, had been around for 3000 years before it started cracking in 2000 (nrdc.org) By 2002, the Ward Hunt has cracked completely through and had started breaking into smaller pieces. The melting ice caps are affecting the earth and its inhabitants in many ways. In this paper, the following concepts and subjects will be
