New opportunities to expand peak the interests of oil industries, shipping, and even tourism. The first arctic oil field was developed in 1930 in the the Soviet Union. From there, the race to control the arctic regions began. Oil became the power of the arctic economy and still is today. Jobs and opportunity were opened up to people who wanted to work in the oil industry. However, present day discoveries show that global warming is caused by the rapid increase in population and oil fields. Now, in present times, climate change and the potential for new development dominate debates over arctic policy control. However, Arctic ice coverage is at a low and temperatures reached up to 36 degrees fahrenheit in November which is abnormal (CQ Researcher 989). As arctic tourism, shipping, …show more content…
The shrinking of polar ice caps is caused by increasing tourism, shipping, and major oil field expansion. As more people and companies begin to travel towards the arctic, the more global warming occurs affecting ice coverage. “Polar ice which has been shrinking at a rate of 12% a decade since the late 1970’s and was at a record in October” (CQ Researcher 994). The rate per year of melting of ice caps is too high and is causing major destruction and arising new problems. As ice melts, it turns to water which unhealthy for the environment. “ Harmful solar energy that would of been reflected off of the ice and back into space is instead absorbed by the ocean, warming water and further exacerbating climate change,” (Brown 2). Because of ice melting, passageways open up for tourism. The once desolate arctic is now populated with cruise ships and people venturing into the region.
In his essay, “Global Warming is Eroding Glacial Ice,” Revkin is arguing that global warming is constantly changing the ...
The environment has become a popular topic this year due to our on-going drought. It has always been a serious issue; something Saukko informs us in her sarcastic essay “How to Poison the Earth”. She uses sarcasm and irony in her essay hoping her readers will do the complete opposite of what she is saying because of the stress she puts on the harming chemicals we use every day. We do not appreciate our environment and take it for granted. This ideal is what Ehrlich's essay “Chronicles of Ice” focuses on by using analogies and scientific definitions to describe aspects of glaciers. The melting of the glaciers introduces us to the topic of global warming and how our society is doing nothing to stop it from getting worse. Gawande’s “The Cancer-Cluster

The fiction story “The Icebound Land” by John Flanagan, it follows two characters, Halt and Will. Will, an ranger aprentice, tries to escape from his captivity of the Skandians with Evanlyn, the princess of Arulean. Halt acomponies Horace to find and save Will from getting traded away. The theme of this story is to save someone important to you at all cost.
Over the last thirty years the United States has been faced with the problem of dependence on foreign countries for oil and the tight control that these exercise on the energy policies and economics of America. Many of these instances include: the oil embargos of the 1970s, the Iraqi invasion of Kuwait in 1990, and the terrorist attack on the World Trade Center in 2001. Since the 1970s, one solution offered to reduce our nation's dependence on foreign countries for oil has been opening up drilling in the Arctic National Wildlife Refuge (ANWR). Proponents say that drilling in ANWR would make the United States more self-sufficient in the area of energy, while at the same time not doing excessive damage to the environment of the area. Opponents of drilling in ANWR cite the environmental problems of off-shore drilling and maintain that this land should be left alone and allowed to stand as an environmental wonder. Given that some environmental groups do not mind allowing technology to invade the environment when it profits them and given the threats of global terror and the ever-increasing dependence our nation has on foreign oil, I believe it is in the best interests of the United States to open up the Arctic National Wildlife Refuge for oil drilling.
First, global warming has an immense impact on Arctic Sovereignty as the rise of greenhouse gases thrive in Canada along with other countries. Within 20 years, the polar ice caps of the Arctic have melted twice as fast compared to before. The loss of Arctic ice can furthermore pose a threat to shipping, as navigating the Arctic becomes increasingly challenging. Finally, climate change threatens the extinction of numerous animal species, namely the polar bear. Hence, global warming poses a major challenge to Arctic Sovereignty and Canada along with other members in the Arctic Council must prevent it.
Do you believe in Witches? Back in the 1600’s they started to think that people were witches. I am not sure why, but they did specific tests to see if you were a witch. There were many different theories to why people started accusing people of being witches. You tell me are there witches or are they fake?
People are responsible for higher carbon dioxide atmosphere emissions, while the Earth is now into the Little Ice Age, or just behind it. These factors together cause many years discussions of the main sources of climate changes and the temperature increasing as a result of human been or natural changes and its consequences; even if its lead to the global warming, or to the Earth’s cooling. In their articles, “Global Warming Is Eroding Glacial Ice” by Andrew C. Revkin and “Global Warming Is Not a Threat to Polar Ice” by Philip Stott, both authors discuss these two theories (Revkin 340; Stott 344). Revkin is right that global warming is taking place. Significant increase of carbon dioxide in the atmosphere is due to human activities combined with natural factors such as volcanic emissions and solar radiation – all together they lead to climate changes and temperatures rising. At the same time, other factors such as deforestation contribute to environmental changes for some glaciers not less than air pollution. However, during global warming not all regions of the planet are affected in the same way, local warming and cooling are both possible during these changes.
In winter, the sun never rises in the arctic because light rays are bent by the atmosphere, however the sun can be seen only when it is below the horizon. Imagine how it would be like without sunlight for 6 straight months during midwinter as shown in the picture below on the last page; it’s breathtaking. The reason it is because the earth’s rotate to the plane of its orbit around the sun.
The use of fossil fuels has greatly increased the amount of atmospheric and oceanic CO2 to a point where it’s ruining the natural flow of the world; the earth’s temperature is rising. As a result, the polar ice caps are melting causing the seas to rise. With only a 1 meter increase in sea level the United States alone could lose over 10,000 square miles of land, and thousands of houses will be destroyed. The effects will be just as prominent around the world: many islands will become submerged, 17% of Bangladesh will be underwater, and tens of thousands of people will be displaced (“Global Warming” 3).
Canada’s arctic has evidently suffered from substantial climate change, resulting in devastating impacts on all systems in the north. Many climate models indicate that these significant changes will only progress in the future. The monitoring of temperatures in the Arctic have demonstrated that, over roughly the past 50 years, there has been a warming of about 2 to 3°C as of 2009. The average temperature in the arctic has increased almost twice as fast than the rest of the world. In 2020, the projected increase is up to 4°C as well as 8°C by 2050. A numbers of studies have shown that, based on previous climate records, there has been issues of rising sea levels, alterations in sea-ice dynamics, and permafrost degradation. Though there have been multiple strategies posed and adopted, the government of Canada needs to develop an arctic strategy that is more proactive and systemic than previous actions. This strategy needs to be global in its goals for mitigation while still monitoring social, cultural, and economic aspects
The climate on the Earth is changing. Ice age is interleaved with the global warming. In the present age, the temperature of the Earth's climate system continue rapidly increase and it leads to global warming. Global warming is the process of gradual growth of average annual temperature of the atmosphere of the Earth and World ocean. The average temperature on the Earth was increased by 0.6C. There are various reasons of global warming, such as human activities, natural events, increasing of gases, such as carbon dioxide in atmosphere and solar activity (Global warming). Nearly 200 countries have signed Kyoto Protocol and they must reduce four greenhouse gases, in order to struggle with global warming. There are several perspectives about effects of global warming on environment. In this essay will be considered the impacts and consequences of global warming . In the process, it will be clarified that there are positive and negative impacts of global warming.
It is an unquestioned fact that the climate is changing. There is abundant evidence that the world is becoming warmer and warmer. The temperature of the global land average temperature has increased by about 8.5 degrees centigrade from 1880 to 2012 (Karr, et al 406). The one or two degrees increase in temperature can cause dramatic and serious consequences to the earth as well as humans. More extreme weather occurs, such as heat waves and droughts. The Arctic Region is especially sensitive to global climate change. According to the data in recent decades, the temperature in the Arctic has increased by more than 2 degrees centigrade in the recent half century (Przybylak 316). Climate change has led to a series of environmental and ecological negative
As the Earth warms sea levels rise. Melting glaciers add to the problem by dumping even more fresh water into the oceans. “The IPCC estimates that melting ice caps and glaciers accounted for about 25% of sea level rise from 1993 to 2003” (edf, 2014). Rising seas threaten to destroy low areas and islands, erode shorelines, damage property and destroy ...
One of the most substantial problems in the world today is global warming. This gradual warming of the earth is in occurrence at an extremely slow rate but it is happening. Many scientists believe that as human’s work and release greenhouse gases into the earth’s atmosphere, it can become dangerous for the long lasting life of humans and our environment. “Unless we take immediate action, the impacts of global warming will continue to intensify, grow ever more costly and damaging, and increasingly affect the entire planet - including you, your community, and your family” (“Global Warming Impacts”). Everyone should be knowledgeable about global warming and the dangers that it brings to our planet. This essay will examine
