Riches Await As Earth's Icy North Melts "Summary 2"



Summary


An international race between many countries includes Canada and Denmark. This race is all for one small island that you couldn’t find on the map, called Hans Island. This huge race is because it’s very rich in oil, fish, diamonds and shipping routes. The global warming has a hand in this island by warming the ice cap faster than any other part of the world. Another reason is that the Arctic holds almost 25% of the world’s undiscovered oil and gas. These reasons make the countries fight to own this small island. Now it’s easy to find the oil and gas faster than before because of the climate changes. Old studies show that the ice will melt in 100 years, but the new studies show something completely different. It shows that the ice will melt in the next 10 to 15 years which is really small term compared to the old one. Now the countries should stop the racing or this continuing ice melting will affect the climate. Nowadays, both countries have sent warships to that island and are waiting for ice melting to get the oil first but there is no risk of war.



Main idea


There is an international fight between many countries for a small island called Hans looking for oil, fish and diamonds.


Opinion


In my opinion, these countries are only looking to make money and ignore the nature and the danger of some resources. I see that while these greedy countries are looking at this money, many people are at risk of this serious phenomenon.

An Inconvenient Truth


We watched a movie called “An Inconvenient Truth”. Many people are not aware of how serious this problem is, and this movie is simply talking about the global warming and how this problem is serious. Global warming is the most critical issue that will affect the whole planet and any life on earth.


The film was presented by former United States Vice President Al Gore and directed by Davis Guggenheim. It was talking about the main reason of Global Warming and how in time the ice will melt and the quantity of the water will increase the sea level by 25 meters which will cause floods. Hurricane Katrina happened due to the global warming. Mr. Al Gore has presented the presentation 1000 times in many different countries to make people aware about the causes of the global warming in our life and how the Arctic life will be affected and suffer.

I think that the film was very interesting for some people because it talks about one of the most important issues in our life which is the global warming. Some people aren't aware of it because they think it is something not true and the scientists have exaggerated. In my own opinion about this movie, I found it boring and not exciting because I knew about this phenomenon a long time ago.

Task 2 blog project

Global Warming is a term used to describe the changing in the weather in the last few years. There are ten special climate areas on the earth: tropical, subtropical, arid, semi-arid, Mediterranean, temperate, northern temperate, mountain, polar, and coastal. There are two major reasons for a region’s climate: the average annual temperature and the amount of precipitation received in the zone. There are many factors changing the earth’s climate, for example, the amount of solar energy, the shape and orientation of the Earth’s orbit around the sun, and the composition of the Earth’s atmosphere. The most important thing that is behind climate changes on Earth is the sun. About 30 percent of the solar radiation reaching the atmosphere is reflected back into space; another 20 percent is absorbed by the atmosphere. In fact, the climate differs from one place to other in the earth because of some another facts; for example, the Earth follows an oval-shaped path and the second fact is the Earth’s axis is tilted at an angle of 23.5 degrees in relation to the plane of the sun. Sunlight consists of radiation with short wavelengths; it’s re-radiated to the atmosphere in a form that consists of a longer wavelength.


The changes in global climate have changed the course of the Earth’s history. The human burn a very large amount of fossil fuels to operate factories, heat homes and offices and to power vehicles, and these activities contribute to the concentration of that CO2 gas in the atmosphere. Many scientists now believe that this change means that the higher concentration of carbon dioxide will inevitably lead to a greater retention of heat in the atmosphere. This phenomenon has been called global warming.
