As the world becomes continually warmer, the effect of climate change in the arctic regions becomes more intense. Within the past 50 years, arctic regions in Canada have experienced warming of 2 to 3 degrees Celsius (Fergal & Prowse, 2007). One of the most important areas in the Canadian arctic is the Cryosphere (Appendix A), which is the area consisting of season snow cover, permafrost glaciers, and sea ice (Fergal & Prowse, 2007). This area is significant because it has provided a stabilized surface for building pipelines, as well as provides access to northern communities (Fergal & Prowse, 2007).
The change in climate has already been apart of consideration for major developmental projects (Fergal & Prowse). Not only are companies preparing for climate change but also the communities are concerned with how the impact will change their access to survival resources such as fish, water, wildlife and forestry (Fergal & Prowse, 2007). It is projected that in 25-30 years, sea ice in the Canadian arctic will be completely melted and which could strongly affect the northern communities (Fergal & Prowse, 2007). This essay will discuss the positive and negative impacts of climate change on transportation for Northern Canadian communities and their accessibility to resources as the sea ice melts.
Transportation Change
As sea ice begins to melt, opportunity in sea transportation strikes as an interesting topic for the Canadian economy. Wintertime shipping has proven to be difficult in the Canadian arctic, due to heavier and thicker ice (Fergal & Prowse, 2007). Summertime has always been a preferable season for sea transportation partially due to the softened ice, and the amount of daylight produced, compared to wintertime darkness (Ferg...

Canada is a very large country, with areas of land in various climate regions, and land regions, thus having many ecozones that differentiate from another. The most populated ecozone in Canada is the Mixedwood Plains; the ecozone we are located in, named after the mixedwood forests that are native to the area. The Mixedwood Plains is one of the smallest of the Canadian ecozones, spanning only 175 963 kilometres squared. The Mixedwood Plains is bordered by three of the great lakes on the southern side of the ecozone, and comes up along the St Lawrence river to southern Quebec, and fills the tip of Ontario. It has rolling plains and small rock formations and escarpments. The Mixedwood Plains contains over half of the Canadian population as it contains some of Canada’s largest cities, including Toronto, Ottawa, Montreal, and Windsor. The Mixedwood Plains has a relatively temperate climate with summers ranging an average temperature of 18o c – 22oc and winters ranging from -3oc - -110c.[2] Native mammals to the ecozone are black, brown and grizzly bears, grey wolves, coyotes and foxes, raccoons, squirrels, and other small mammals. Avian species include brown sparrow, hawks, crows, cardinals and bluejays. Fish are bass, trout, carp and pike. The Mixedwood Plains is made up of about 40% water, and contains over 20% of the worlds freshwater. One of the major problems in the world today is freshwater shortage. Because we have ample supply, we don’t notice, but much of the world is short on water. There are more water resources, but one of the largest is being quickly polluted and populated by invasive species .

Permafrost is permanently frozen soil which hasn’t melted in 2 years or more, it also makes up 24% of the land in the Northern Hemisphere and it stores massive amounts of carbon inside of it (Insert Citation). Permafrost contains large amounts of frozen organic matter and if this organic matter thaws out and starts to decay it will release carbon into the air. As a result of global warming and climate change, permafrost is at risk of melting, releasing the carbon trapped inside, it has been estimated that the permafrost contains 1700 gigatonnes of carbon inside of it (Insert Citation), which is double the amount of carbon in the atmosphere already and there is no way to stop the permafrost melting besides slowing it down by reducing our emissions. Figure 1 shows the northern hemisphere and how much of the land contains permafrost. It can be seen that there is a significant amount of permafrost in the northern hemisphere and if this were to melt there would be a dramatic increase in greenhouse gases in the atmosphere.
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.
In recent decades, the contentious issues surrounding climate change and the corresponding effects it likely exerts upon contemporary civilization has developed to become one of the most pressing areas of concern afflicting humanity (Armstrong, 1). Currently, climate change has started to demonstrate its potentially calamitous consequences upon human subsistence practices, and has even begun to alter the very environments that entire societies reside in, theoretically endangering them in both instances (Armstrong, 1). Though the hindrances inherent in climate change are potentially devastating to the preservation of modern society, the problem of climate change itself is not one that is exclusive to the contemporary era. Rather, the harmful
The topic of climate change and global warming has always been one of great debate and controversy; however, it’s clear to see that Canadians should take precautions to avoid the problems their country faces. The Canadian government should do everyth...
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
In this essay, the effects of climate change on agriculture and how to manage it shall be discussed. Climate change has and will greatly affect agriculture. As time progresses, the effects of climate change will worsen and become detrimental. Mendelsohn and Dinar (2009:1) state,” if future climate scenarios lead to a widespread reduction in food supply, there could be massive problems with hunger and starvation”. Climate change is a change in global climate patterns which is mainly caused by the increased levels of atmospheric carbon dioxide produced by fossil fuels. The writer chose this topic because climate change is a global problem that will pose a threat to people’s lives around the world and must be dealt with sooner than later.
Now, sustainable development and quality of life are crucial to the well being of our nation. Thus, I have pondered many a year on this very important matter and have consulted a very knowing Canadian of my acquaintance at the World Wildlife Fund (WWF). The amount of natural resources in this country being usually reckoned infi...
For years to come there will always be a speculation on whether the climate change has really taken place or not. Many believe that large companies launched this topic in order to benefit from it in profit, as there are also those who are convinced that this are consequences that have emerged from human mistakes in understanding the environment. As humans are struggling to trust one another whether it is just a big conspiracy or not or environment changing itself, we are slowly starting to feel the effects of climate change. Because of the gasses (CO2) that are in the air, atmosphere is getting warmer, thereby triggering the Greenhouse effect. Almost 70% of emitted gasses in air are CO2, which leads us to believe that this is the main cause of Global Warming. Since it is billions and billions of metric tons per year that are being released in air, many scientists conclude that temperature will most likely be more higher in twenty years from now, than it was in near past.

There are several factors that are attributing to the future of the Inuit tribe, however, the most important is the disappearance of their natural environment the arctic circle. Global climate change, with its resulting loss of sea ice, has opened up access to the Arctic Ocean as never before. Moreover, the rate of global warming and the pace of development are accelerating. Stakeholders have different ideas on how to handle these changes. Depending on one’s perspective, the pace of development seems to be either too fast or too slow; and, like most contentious issues, the best solutions may lie somewhere in the middle.
Climate change is currently one of the greatest challenges facing our species. This case study report will examine issues related to food production in relation to climate change. In this regard, the focus will be on the Peace River Country, which is a parkland region that spans from northwestern Alberta to the Rocky Mountains in northeastern British Columbia and around the Peace River. As part of its examination, this report will explore the local environment conditions, and offer predictions of what lies ahead in areas of economic development, the food practices including how climate changes may affect the local food production, as well as other future and predicted changes in the area.
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
The book by David Archer (2009) includes details that will make the readers understand the future of climate change as well as past events that have changed the present climate, as we know it. David Archer is a professor of geophysical sciences at the University of Chicago and has done many public presentations on the earth’s climate change before releasing his book, the long Thaw.
