a) Suggest why some groups and communities view the melting of Greenland’s ice sheet as an opportunity rather than a threat. (10)

Some groups and communities view the melting of Greenland’s ice sheet as an opportunity rather than a threat because the melting ice creates some commercial advantages for the Arctic region; the Northern Sea Route, North of Canada, is the quickest way of travelling from Europe to the Pacific and Asia. This also increases the tourism opportunities because 30% of Inuit earn income from sculpture and printmaking for tourists, as the tourist ships are able to transport to the northern Canada.
As the rapidly melting ice offers commercial opportunities in shipping, tourism and oil and gas extraction, the world’s largest economies are struggling but as well as trying to achieve and get hold of the region within the Arctic. A region in the Arctic thought to be contain 30% of the world’s undiscovered gas and 13%% of undiscovered oil. In addition, more oil can be used by groups of Inuit for essentials like the uses of fossil fuels. In Alaska, due to the new drilling activity, it creates new job opportunities and incomes for the local economy, which means more Inuit, get the job opportunities like this. Furthermore, there are currently four more mining operation being setting up and soon, it will provide jobs for natives in Greenland.
In 2007, the Northwest Passage between Canada and Arctic melted enough to allow shipping for the first time and also allow more opportunities for activities like offshore oil exploration. Analysts think the economic impact could be important because new and expanded shipping routes can reduce the time between Asia, North America and Europe, and oil companies like Royal Dutch Shell are eager to get the opportunities for fossil fuels, which believe lies beneath the pristine Arctic waters.

b) Examine the ecological impacts of global warming for Arctic areas. (15)

In this essay, I will explain the ecological impacts of global warming for Arctic areas, to the trees, plants, natives and animals.

In recently, the 20% of solar radiation is absorbed from the ice caps, since the sea, plants and rocks have the low albedo. This is because of oceans are darker than ice and snow; it absorbs more energy than it reflects, which causes the warming effect. Due to warming effect, it melts more ice and creates a cycle called the positive ice albedo feedback, which in turn causes an increase in average temperature, and therefore increases ice melting even more, and so on. This negative feedback mechanism will also further greenhouse gas emissions by the thawing of permafrost. Beneath the permafrost found on arctic tundra, are thousands of gallons of methane, trapped there for thousands of years. As this permafrost begins to melt, the methane will be released, increasing the temperature and creating a similar feedback mechanism to the albedo effect stated above.

Increasing temperatures lead to the treeline moving north and to higher altitudes, causing a distortion in tundra ecosystems due to the warm climate and other plants competing and take over, permafrost thawing out, the change of the food chain due to the spread of species, such as spruce bark beetle in Alaska like competing with other animals can affect predators or preys. Increasing temperatures also lead to increases in the number of northern coniferous fires in Arctic Russia. Burning tens of millions of hectares each year causes the loss of 0.8% of the world’s coniferous. Boreal ecosystems are vital and accounted for 37% of the world’s carbon pool on land, and are effective at sinking carbon. Burning tens of millions of hectares can result in the release of carbon dioxide and reducing the amount of homes for species.

Increasing temperature has many effects on Arctic biodiversity including the northward movement of more southern species, shrubbing and greening of the land, changing plant communities, increases in migrating foreign species displacing native Arctic inhabitants and Arctic Biodiversity Assessment Trend 2010 Report shows the new disease starts to spreading, can possibly harm the natives as well as animals. Changes in biodiversity are creating both challenges and opportunities for Arctic people, like less southern species to be found and less Arctic people will be able to find them for foods supply or essentials.

As result in the release of methane and CO2, biological processes taking place in the Arctic Ocean and favour the retention of pollutants, which is then enter the food chain. As a result, the people and ecosystems are exposed to high levels of heavy metals and radiation. Also, the climate change is causing some changes in release of pollutants; degradation of highly toxic chemicals.

The shrinking ice sheets have affected the marine species in the Arctic and the food chain. The warmer water has decreased the number of marine plants, which many smaller fish feed on. The reduction in smaller fish species has affect the higher up food chain, such as cod and halibut that in turn affects larger marine species, such as seals. This results in the negative multiplier effect. The small number of seals stock reduces the food supply for polar bears. Furthermore, the melting Arctic ice has had a disastrous impact on polar bears because normally, they hunt seals on the ice but the faster the ice melts and the faster annual ice melt, shorten their spring hunting season. E.g. Hudson Bay is now ice-free for three weeks longer than in 1985 and polar bears have the less time to hunt the reduced numbers of seals. However, the female polar bears rely on the cold spring to build up their fats to ensure their survival during the summer but currently, each animal lose 80kg of fat during the longer summer, making them vulnerable to disease and reduce their ability of reproduce or feed their cubs.

As explained above, the melting of the Arctic ice is destroying seal hunting grounds and so limiting access to Inuit food supply. Also, the melting of glaciers into the arctic waters is causing less fish to reside the now fresh waters, causing polar bear and seal numbers to decrease as there food source disappears. Such an impact to the Inuit food supply and main source of income would mean that communities would have to import food instead of hunting it, which would be incredibly expensive (up to USD$ 1 million per year) due to their high protein requirements to help them cope with the harsh environment.

Overall, there are many ecological impacts due to the increased temperatures, global warming, permafrost thawing out and positive albedo feedback. The impacts are small spaces for seals, polar bears and plants to live in, resulting in migrating to the north. Due to the increased temperature, the treeline is moving north, where it couldn’t survive.

...Collapse- book is about a history topic about how societies choose to fail or survive. The main characters are historical people and unknown kings of Mayan cities or Easter Island villages. Jared Diamond tells the story of the Viking explorer Erik the Red, who discovered Greeland and Vinland (Terranova, in Canada). Another character is captain Olafsson, a norse sailor who wrote the last news about Greenland in 1410. Another main character is Christopher Columbus, who arrived at Hispaniola in 1492, but now this island is two countries, the Dominican Republic and the Haiti. Diamond studied the politics of two presidents. the dominican Rafael Trujillo, who protected the enviroment and the dictator François, Papa Doc, Duvalier, who decided on politics of deforestatation of his country, Haiti. The author considered the bad politics of another main character, king George II, who was interested in sending merinosheeps from Spain to Australia, an idea which was succesful from 1820 to 1950 but then the farmers understood their lands lost fertility. Another main character is Tokuwaga Jeayasu, a shogun of Japan in 1600, who prohibited Christianity in 1600 and protected his country againt deforestation.  The book takes us to a lot of places around the globe: Mayan cities, Rwanda, Viking colonies of Vinland or Greenland, Haiti and Dominican Republic, Easter Island and Polynesian colonies in Pacific, and the Chaco villages in New Mexico (United States).

The World in 2008

...to the general election in November. The betting is that the winner will be a Democrat—with a strong chance that a Clinton will again be set to succeed a Bush as leader of the free world. China, meanwhile, will hope to use the Olympics to show the world what a splendid giant it has become. It will win the most gold medals, and bask in national pride and the global limelight. But it will also face awkward questions on its repressive politics. America and China will be prime players in the matters that will concentrate minds around the world in 2008. One of these is the world economy, which can no longer depend on America, with its housing and credit woes, to drive growth. America should—just—avoid recession, but it will be China (for the first time the biggest contributor to global growth) along with India and other emerging markets that will shine. Another focus of attention will be climate change. As China replaces America as the world’s biggest producer of greenhouse gases, serious efforts on global warming depend on the serious involvement of those two countries. If 2007 was the year when this rose to the top of the global agenda, in 2008 people will expect action. It is striking that green is a theme that links all the contributions from political leaders in this volume, whether at the city level (Michael Bloomberg), the national level (Felipe Calderón, Nancy Pelosi, Nicolas Sarkozy) or the supranational level (the UN’s Ban Ki-moon, ASEAN’s Surin Pitsuwan).

This will have far-reaching consequences. Commercial airports are powerful economic engines, generating 10.5 million jobs and $1.2 trillion for the U.S. economy, according to a new Airports Council International-North America study.
