How Does Global Warming Affect Loons

The Arctic Sea Ice is melting or slowly disappearing and it is said to be one of the reasons of global warming. What is happens is that the Arctic Ice it melts a little and gets smaller during the summer season and than during the winter season the ice gets bigger and expands over the Arctic Ocean, “a freeze-thaw cycle that in the Arctic has been dramatically altered by global warming (Global Warming Effects).” The Arctic Sea Ice in the past could grow up to 3 meters, which is around 10 feet, but now the average thick ness is becoming much less, and some scientist are afraid that in a few decades there might not be any sea ice during the summer (Global Warming Effects). Another major thing that has been discovered is that the amount of ice

The polar ice and climate change is not only affecting the arctic, but it is affecting the human race, too. The ice melting as we all know, but what we don’t know is what is the after affect of ice melting. While the ice is melting it thins out and that causes the ice to spread. The ice has gone through Russia and now to Canada in four- five years. This distance of ice spreading used to take six-seven years. This means the ice is now melting more pushing the other ice faster! What some people may not know is that as the ice moves it carries pollution, and when it is spring and summer all the ice melts and pollution goes into the ocean.

Arctic ice caps are melting, causing many animals to find either a new habitat or new food, which are both extremely challenging. For example, in Document A, sea lions

There are about 100 different species of animals there, all of which are affected by climate change, but polar bears the worst. Polar bears are the most sensitive to the rapid change in climate because most of their life is spent on sea ice. With the temperatures rising in the Beringia Upland Tundra, the sea ice they thrive on is melting at a very high rate (Powell). Without this ice, the polar bears will not be able to easily move around to mate with other polar bears. They will also not be able to successful hunts on seals because the seals will see them swimming and swim away before anything bad can happen to them. If there was not a shortage of ice, the seals would not see the polar bears on the ice and they would swim closer to the surface. Another challenge the polar bears will face is that they will be eventually forced to go on to the seashore. This would be catastrophic because there would be and increase of competition for food. This could start massive stampedes that could kill polar bear cubs due to adult polar bears trampling them. As of now, there are only 26,000 wild polar bears alive. By 2050, it is predicted that two thirds of all wild polar bears will be gone. By 2100, it is predicted that polar bears will become extinct if nothing is done about global warming and climate change (Kliskey). Another animal in the Beringia Upland Tundra that is affected by climate change in

The arctic is estimated to be ice free by 2030 due to global warming and the melting of the ice caps.

In the Northeastern part of Russia, summers are cold and winters are colder. The Siberian Tundra is home to many abiotic factors such as strong winds, little precipitation, and short summers days. With poor soil and permafrost, the tundra could soon be gone, or at least cause dramatic changes to the earth. According to Evans (2002), the grounds of the Siberian Tundra are misty during the summer. The average temperature in the Tundra is 37 to 54 degrees yet, in these short months of summer, the Siberian tundra has a permafrost layer that is starts to disappear. This loss of permafrost is resulting in the rise of carbon emissions, which contributes to global climate change. Through research, we can better understand the disappearance of the permafrost layer in the Siberian tundra. How and why is it disappearing, and what impact this disappearance is having on the tundra, and on a much larger scale, the Earth?

Stunted Again” written by Michael Pearson, the Earth is in trouble due to the decrease in Arctic

As important as it is, Arctic coastal sea ice plays a vital role in dynamics of the coastline, covers stretches of open water which serve as important biological habitats, and serves as a platform for a broad range of activities by residents and industries (Druckenmiller et al., 2009). Sea ice is also important because it is used as a platform for harvesting seals and whales in spring, transport of personnel and supplies to camps, and as a network of trails (Druckenmiller et al., 2009). Dangerous effects of climate change include “ice breakouts” which are when large chunks of ice that whalers are using as working areas break off of the main ice blocks and take whaling camps out to sea (Druckenmiller et al.,

At the present rate of global warming most of the frozen portions of the Arctic may disappear by the end of this century.

In Henry Fountain’s “Alaska’s Permafrost is Thawing”, Fountain discusses how Alaska’s permafrost is slowly thawing away. Alaska is known for its vast, snowy landscape, but that soon could be all gone. This article is directed towards people who are interested in the warming of Alaska. As the Arctic is warming at an alarming rate, wildlife is slowing disappearing and sea levels are rising.

Tundra, as one of the most sensitive environments, is extremely threatened and endangered. As a consequence of the cold climate, global warming drastically affects the tundra. The effect of humans on tundra environments is also very damaging. Humans develop and damage the natural area, and pollute the air. (National Geographic, 2013)

The latest survey conducted by the US Forest Service shows that as many as 97% of the animals of the Arctic could be affected as a result of the observed warming. The climate change may occur faster in the Arctic region. Scientists have developed computer models to predict changes in the environment and their impact on the 162 species of birds and 39 species of mammals in the Arctic.

The Arctic formally encompasses all of the Earth’s land and ocean areas north of the Arctic Circle, but the Arctic region describes a larger area with linked ecosystems and similar ecological challenges (Gale Encyclopedia). The arctic tundra has one of the coldest and longest winters and a very short summer, but event then there is only a brief period of time where the sun shines and the temperatures are mild. The arctic tundra is home to few different species and organisms because the temperatures cause issues for organisms that need to maintain a certain body temperature. A few of the organisms in the Arctic tundra are penguins, Polar bears, fox, and different species of birds, as well as caribou, wolves, and grizzly bears. The Arctic Tundra forces many species to fight for survival and adapt to the environment but these adaptations cause changes to the environment and the other species living in it.

As the impact of global warming on the environment exponentially expands, issues such as increasing air and water temperatures, rising water levels in coastal regions, growing severity of storms, polar ice melting, increased acidity in oceans, and altered environments and habitats also worsen at an alarming rate (Denshak). These are not unknown concepts, but what is less known is the effect that global warming has on the Arctic region and its biodiversity. This specific issue primarily deals with climate change in the scheme of melting polar ice shelves, rising temperatures, and increased acidity of the world’s oceans. Since the Arctic region has a very different, more fragile

The melting ice caps are having a dramatic affect on the polar regions of the earth. For example, the average temperature in the Arctic is rising twice as fast than the rest of the world (nrdc.org). The once prominent ice is now melting at a dramatic speed, which is affecting native people, wildlife, and plants. When the Ward Hunt Ice Shelf splintered, the freshwater lake that it surrounded drained into the ocean, along with the ecosystem that inhabited it. Polar bears, whales, walrus and seals are changing their feeding and migration patterns, making it harder for native people to hunt them (nrdc.org). Because of the flooding, entire villages will be uprooted order to avoid being swamped. Also, the Arctic coastlines are beginning to move as well. The melting ice caps are threatening the native peoples’ cultural identity and their very survival. Ice-dependant animals, such as walruses and ring seals will be greatly affected by the melting ice caps (treehugger.com). They have fewer places to rest on, as well as fewer places to hunt. If the ice caps keep melting, their lives will become in great danger. The melting ice caps are not only affecting the Polar Regions, but they are also affecting the rest of the world as well in the form of rising ocean levels.
