Brief Overview of Reports of Intergovernmental Panel on Climate Change (IPCC) Since 1990 and Reactions • In its first 1990 REPORT, the IPCC refrained from suggesting that the 0.5 degrees Celsius rise in the average global earth temperature since the start of the 20th century was due to humans or from natural variability. • In its second 1995 REPORT, the IPCC did not move much from its earlier position of the origin of higher global temperatures. However, it did say that subsequent research

to point out that the consumption process is not as simple as an individual having the need or want for a product. The consumer can be motivated by the desire to feel a certain way. For example, my most recent purchase was a winter coat. After the arctic temperatures we had in the Western New York area over the last few days, I decided it was time to invest in a nice warm winter jacket. I first started to look online then I visited a few stores but I didn’t find anything I really liked. If the consumption

The fast melting Arctic region has emerged as a conflicting and controversial topic for many countries. Due to the increasing effects of global warming, the Arctic icecap is said to be melting faster than expected. The meltdown has decreased the area covered by ice, substantially reducing the Arctic icecap to only half the size it was 50 years ago. This irreversible warming can be seen as beneficial due to its great economic potential and has consequently provided the Arctic with strong regional

8. What are amphipods and copepods? Why are they important in the food chain in the Arctic Ocean? What do they feed on? Amphipods are animals that belong to phylum Arthropoda and class Malacostraca that has no carapase (protective shield covering the back part of an animal) and has laterally compressed bodies. Basically, Amphipods are shrimp –like in form. Copepods are animals that also belong to phylum Arthropoda but to a different class Maxillopoda. They are usually 1 to 2 millimeters long

greenhouse effect or other climatic change, the Arctic ice cap would start to melt. This ice cap contains the equivalent of some 680,000 cubic miles of water. More than 200 million people live on land that is less than 3 feet above sea level. In the United States several large cities have low average elevations. Three examples are Boston (14 feet), New Orleans (4 feet), and San Diego (13 feet). In this exercise you are to estimate the rise in sea level if the Arctic ice cap were to melt and to determine whether

The Seriousness of Global Warming Luis Green Columbia Southern University The Seriousness of Global Warming One of the most controversial and popular environmental topics is the effects of global warming on the planet. Although global warming has become a more talked about issue in the last few years, scientists have been warning the world for a long time about the devastating impact that human related greenhouse gases is having and will continue to have on the environment. Many do not realize

PARKINSON2 (Received 10 November 2005; accepted in revised form 25 January 2006) ABSTRACT. Polar bears depend on sea ice for survival. Climate warming in the Arctic has caused significant declines in total cover and thickness of sea ice in the polar basin and progressively earlier breakup in some

The Sun's rays hit the equator at a direct angle between 23° 26′ 22″N (Tropic of Cancer) and 23° 26′ 22″S latitude (Tropic of Capricorn), the closest point, of course, depending on exact time of the year. Solar radiation that reaches the atmosphere is most intense between these latitudes (the Tropic

Alaskan Oil Exploitation Alaska Alaska is an American state which borders Canada to the West, its coastline is the Arctic Ocean and the majority of the land is within the Arctic Circle. Due to its location in the Arctic Circle, Alaska experiences extreme cold temperatures. For 8 months of the year it is sub-zero, with the months of January and February recording temperatures as low as minus 30. The ANWR, a wilderness area, is located to the north east of Alaska and covers nearly 80,000
