Polar region

Gore presents a graph demonstrating a connection between CO2 levels and temperature during 600.000 years based on samples of polar ice profundos.1 In that time period CO2 levels have ranged between 180 and 280 parts per million ( ppm). The level today is about 400 ppm, well above what has been seen in more than half a million years. Gore said that that level will…

semi-periphery is a crucial link in this system of unequal exchanges - the “intermediaries with the periphery, conveyor-belts of surplus value” (Wallerstein 1974: 241). The semi-periphery does not just act the “core” economically to some peripheral regions, they can exert influences politically and culturally through their limited hegemonic powers in the same fashion as core nations, sometimes to their own national agendas sometimes on behalf of core nations. They also serve as examples of…

all the ice, this expedition, however, did provide a reliable view of this part of the world that has not yet been properly explored. It is because of this adventure, that the world found out about the Arctic Circle and the whales that live in the region that is now being used as a hunting…

the center of both economic and environmental controversy as it holds potential for the production of both oil and natural gas. The ANILCA’s most controversial piece was the decision to defer drilling and petroleum exploration in the coastal plain region of ANWR known as the 1002 area (Figure 1). Petroleum is a valuable economic resource that is used in everyday life from the generation of electricity to fueling transportation to making plastic and synthetic goods. Yet despite modern society’s…

Anatomy of cerebral cortex: Brain is most complex organ in human body. The ability of brain for its functioning normally is manifestation of various activities it takes participation in various activities of day to day life, being it hidden from the view or perceptible, like walking, smelling, thinking, laughing, speaking, and hearing. These manifestations are results of very coordinated and complex electrical and chemical activity within and between the cells those makes up our brain. Abnormal…

changing the planets weather in many different regions. When a region 's climate changes it becomes a domino effect and will change everything around us. This change of weather results in more frequent hot days and fewer cold days.(NASA). This proves that severe storms and droughts will become more and more frequent as time goes on. QUESTION: about california. 2.) According to panda.com global warming is causing a huge problem in the arctic and polar regions on Earth. The icecaps are melting…

system level of analysis, the international system is defined by anarchy—the absence of a central authority (Waltz). United States and the Soviet Union were sovereign and thus were autonomous to each other. The Cold War in the 20th century was a bi-polar competition between the United States and the Soviet Union known as the cold war between the two superpowers with opposing ideologies. The United States and its allies were supporting capitalism and the Soviets and their allies standing by…

Starting with prokaryotes—as earlier discussed, prokaryotes have nucleoids—which are regions where their DNA is stored, not membrane bound—plasmids are common, they have no introns and they do not have histones. Eukaryotes have a membrane-bound nucleus where their DNA is stored, plasmids are rare, they have introns (parts of a split gene…

The contextualisation for the expansion of America was the main reason Frederick Jackson Turner undertook his hugely influential text ‘The Significance of the Frontier in American History’. It described it as a monumental event in American history as America sought to find and establish its exact culture in the modern world. They were distinctly different from their colonial past but where exactly along the way did they morph into their present day state. Turner stated that it was the press…

Journeys for Fame Competitiveness is like a wild animal. Once aroused, it can’t be controlled. In the year 1911, Roald Amundsen, a figure in polar exploration, began his long journey to the South Pole, in Antarctica. He became the first person to ever succeed this dangerous objective. Only 16 years later, in 1927, a pilot named Charles Lindbergh prepared to fly from New York all the way to Paris. A $25,000 award was set up by a hotel owner in New York City for whoever could accomplish this…
