¶ … climate change in the Polar Regions and what climate change means to the future of these areas. The Arctic and Antarctic regions of the Earth are already showing severe signs of climate change. As more of the snow and ice melts in these areas, they are reacting much more quickly to global warming. That is because the snow and ice reflect the suns rays and keep the temperatures from rising. However, as more land is exposed by melting snow and ice, the earth adsorbs the sun's rays and then warms up, making the snow and ice melt even faster. The Environmental Protection Agency (EPA) notes, "Average temperatures in the Arctic have risen at almost twice the rate as temperatures in the rest of the world over the past few decades" (Editors). They also note that the Arctic is expected to show greater rates of warming than anywhere else on Earth. As the sea ice disappears, animals dependent on it, such as polar bears and sea lions, could see drastic reductions in their populations, and entire cities and towns could be lost as the ground becomes unstable as ice continues to melt.
Many people still do not take climate change seriously, and that is part of the problem in finding a solution. Perhaps if more of what is going on in the Polar Regions really became public knowledge, the people would truly see that climate change is already happening, and affecting the lives and livelihoods of many people. Many of the Native Americans in the Arctic survive on the animals that live there, and if the bears and seals disappear, they will have no way to sustain themselves. There have been some reports and publicity about the polar bears and their plight, but the Native Americans have not made nearly enough information available about what is happening to them and their villages. More people should be made aware, so they can see the very real effects of global warming, and see to expect much worse in the future.

Climate Change Projections Expected Impact on World Agricultural The objective of this work is to research climate change which is a critically important issue and is no respecter of person in that it affects all upon the earth, man, beast, fish, fowl, and organism. The water temperature will be affected, the air that is breathed each and every element upon, in and surrounding mother earth will experience collectively the changing of earth's
Geomorphologic evidence of glacier fluctuations in Iceland during the Late Holocene is abundant. Furthermore, Iceland has a unique documentary record of ice-front positions between the times of settlement, around AD 870, to the early 20th century. Many of Iceland's larger outlet glaciers have been systematically monitored since 1930. Consequently, a general description of glacier conditions exists for the past/1000 years, in addition to a detailed knowledge of ice-front fluctuations
Climate Change Introduction and Claim Climate change has occurred throughout the earth's history. Ice ages and other radical transformations to the earth's atmosphere have led to dramatic consequences of life on the planet. Ample scientific evidence shows that climate change is occurring rapidly now, and that much of it has been driven by human activities. Moreover, climate change can have serious consequences for life on earth. According to NASA, the recent climate

For many people, global warming is primarily relevant to them in regards to the weather. They assume that when it is excessively hot, this is reflective of a shift in the global climate and when it is cold, this is a sign that global warming is not really as bad as it might be. However, this is far from the truth. While changes in weather may still be present during
Climate Change on Marine Mammals Sustained scientific observations reveal and alert everyone that climate change has asserted alarming effects on the oceans (Simmonds & Isaac 2007). Scientists agree that these effects are likely to be in the form of alterations in prey distribution and volume. They also agree that the more mobile species of marine mammals may possess enough resilience to adapt to the changes. But the extent of their
