The Arctic region affected by global warming includes the town of Barrow, Alaska. Barrow is considered to be the northern-most population in North America. There are about 4,400 people living in Barrow, 68 % being Alaskan natives. The Arctic Climate Impact Assessment has stated that Barrow's average temperatures have risen 2.5-3 ° C (4 E F) in the past thirty years alone (Handwerk, 2004). Global warming affects the indigenous peoples in many ways. The most obvious way that it affects them is through the food supply. Native Alaskans depend on hunting polar bear, walrus, seal, and caribou for subsistence and the preservation of their culture (Impacts of a Warming Arctic, 2004). Another fairly obvious way that the global warming affects the people of Alaska is through the melting of permafrost. Melting permafrost causes the sinking of homes, roads, and other infrastructures. The damage that the permafrost causes to roads alone costs the state almost 33 million dollars every year ( ).
There are two main types of permafrost. Continuous permafrost does not thaw at all during the year. Discontinuous permafrost's upper layers thaw during the warm seasons (Glossary, 2004). Distribution of different permafrost types is shown in . The continuous is located farther north than the other two types because the temperatures are cooler. Discontinuous is not actually permafrost, but rather a frozen soil formation because is does not meet the exact definition of permafrost. Continuous permafrost has a top layer called the active layer which thaws every year. The melting of this ice-rich permafrost is extremely harmful to the earth's surface. This has raised concerns for the stability of roads and other various structures, especially in the areas located in the Northern region of North America (Impacts of permafrost).
Solutions to the problem of upheaval in roads can be solved by: thermal piles with radiator tips and insulators such as rock and foam panels under roads. The only global solution available is to stop the green house emission now. The affect of halting emissions will not be seen until many years down the road, but if we don't stop them, then the global warming situation will never be solved.
The problem of global warming is not something that can be solved in a finger snap; it will take many years to fix the damage that we have done. Stopping the production of green house gases now will help greatly in the future.
Kellog of the National Center for Atmospheric Research in Boulder, Colorado has written an article called "Response to Skeptics of Global Warming" in which he responds to many of the objections that have been raised against global warming.
Instead of idly debating the precise extent of global warming, or the precise timeline of global warming, we need to deal with the central facts of rising temperatures, rising waters, and all the endless troubles that global warming will bring.
Some believe that a dramatically dangerous warming is taking place in the overall global climate, a problem that is referred to as "global warming." This paper will attempt to explore this very issue.
is defined as the analysis of accumulated weather data for long term patterns and trends.
Global warming is our global problem and many a people contemplate over it a lot. If the problem is in your mind and you want to write on it then one the best options is to write it in persuasive essay form. Persuasive essay allows you to state your stance very clearly and directly and a chance to elaborate your point of view in the form of arguments. Writing persuasive essay on global warming will allow you to say all you want to say in a proper and rational way and attract the attention of people in a positive way.
So, state whatever position you are taking on global warming. This statement should be rational, not imaginative. It should be in interesting style and structure. Here I would like to elaborate a little how the persuasive essay will work here. You can use your own interesting ideas in and about the essay.
Climate change in the context of this paper refers to changes that result from human activities, especially as these changes relate to the issue of global warming.
If global warming is indeed happening, it is the greenhouse gas effect that is believed to be the most responsible.
There are some scientists who do not believe that there is enough evidence to support the idea of global warming.
This essay will examine the main effects of global warming by looking at the threats to wildlife and habitat, rise in sea level, and health impacts on humans....
One author wrote that there is "...general agreement that increasing carbon dioxide will produce warming due to its ability to absorb in the infrared radiation" (Lindzen, 289).
There are studies that have indicated that no significant change in the overall global climate has yet taken place.
The Arctic provides important natural resources to the rest of the world; these resources would be greatly affected by the global warming crisis (Berner etc. al., 2004). Areas where water is prevalent in its frozen state are affected the most by the rising temperatures (Armstrong). Arctic areas, including Alaska , have undergone the greatest temperature increases of any other area of the world. These temperatures have risen almost 6 E C, unlike rest of the world's average 0.6 degrees C increase.
