The Role Of Climate Change In The Arctic

1384 Words6 Pages

The Arctic has a great impact on the world 's overall climate, and the rapid increase of temperatures is dramatically altering the world 's environments. The change is altering ecosystems, animals, indigenous people, as well as other areas. Climate change should be one of the world’s most pressing issues, because of the effects on the ecosystems and future generations. If these conditions were to continue at the rate in which it is increasing then soon it will be too late to do anything about it. It is a fact that the Arctic’s ecosystems are changing. The Arctic contains multiple ecosystem, all intertwining and codependent on each other, when one changes all have to adapt to change and sometimes the change is too rapid. Arctic plants are fortuitous but the …show more content…

In Wildlife in peril as the Arctic melts). The plants dispersing makes it harder for them to reproduce and grow, and with the plants comes animals that is another contributor to the plant’s demise. Another way the Arctic is changing Is in the sea ice surrounding it. The Arctic’s sea ice is melting at a rapid rate and the damage it is having on the world is almost irreversible. Since 1980 there has been a 30% drop in sea ice which is an alarming number for a short period of time (Kolbert 27). The drop in sea ice will result in very different environments. For example the Canadian Arctic Archipelago has more than 36,000 islands all connected my sea ice if

Global warming is affecting the Inuits by the heat of the sun is melting the ice and it is not helping the Inuits. It is not helping them because the ice is melting and they need the ice to help them hunt. At 34.28 it talks about how if they don't have the ice then the Inuits will be in trouble if it melts. Also, if it melts then that will affect the food and the animals they hunt. When it talks about the ice melting and the animals that they hunt they mean that the majority of their food is in the ocean and if it becomes warm the will go away or even die.

Some animals live and stay in the tundra while others migrate to another location. Animals that live and stay in the tundra include some birds like the ptarmigan and some mammals like the musk ox, arctic hare, and arctic fox (Woodward).It’s incredibly easy to destroy the tundra because of the lack of variations in the number of plants and animals. If something happens to the permafrost or if a species becomes extinct, the whole ecosystem may collapse. All species in the tundra are significant because the food chains there are very simple. A food chain can consist of an arctic fox eating a lemming, which devoured plants in the tundra, like mosses.

The arctic tundra biome is a biome located in the arctic circle, in such places as north Canada, Russia, Alaska, Iceland, Finland, and most of Greenland. Covering approximately 20% of the Earth 's land surface, the arctic tundra biome is the coldest biome on Earth, with winter temperatures averaging at -34°C (-30°F), and summer temperatures of around 3-12°C (37-54°F). The moderate summer temperature allows this icy biome to sustain life. Yearly precipitation is a low 15-25 centimetres (6-10 inches). The ground in a tundra biome has very low nutrients,which accounts for the low amount of plant life.

In Nunavut there is prevailing and widespread belief among hunters that climate changes are already well under way. Here, they now see an alarming melting of sea ice earlier in the spring and a later freeze –up in the fall, all due to global warming. There is now also the appearance of flora and fauna, never before seen in the region. There is widespread general agreement among the population that there are climate changes occurring here now and these changes are becoming a source of growing local concern. Nunavut’s capital Iqaluit, population about 4300, the old Frobisher Bay, is now the largest town in Canada’s entire arctic.

In the winter, the water is absorbed and then frozen, which forms cracks in the ground (shown in the picture). Arctic Moss slowly grows and overlaps with the older moss as time goes on. This causes the moss to be lacking many nutrients. Labrador Tea: The Labrador Tea plant can be found in North America and in Greenland. The plant grows up to 4 to 5 feet.

This article discusses the increase in meltwater coming from the Greenland Ice sheet due to global warming and how this affects the number of nutrients that get delivered to the ocean. The scientist’s in this study accumulated four years of data which is consistent with and backs up their hypothesis. The data the scientists collected was from the Leverett Glacier which is located in the Greenland Ice Sheet. They found a strong correlation between the amount of meltwater and the number of nutrients. When meltwater increases, nutrients seem to increase as well.

Animals of the Arctic face having to adapt to the treacherous environment and weather, doing all in their power to stay alive. Melting icecaps of the North, politics and the environment are rapidly changing. Currently, Arctic sovereignty is in dispute between the Arctic countries over resources, trade, and territory. The message presented in the source confidently exemplifies the opinion that in the 21st century, the Canadian government is obligated to pursue the sovereignty claim over the Arctic, regardless of the international opposition from America and the Arctic countries. These countries are Russia, Denmark, Finland, Iceland, Norway, and Sweden.

The amount of arctic sea ice is declining more than ever. Polar bears are being greatly affected by the decreases in sea ice. (Doc A) This is affecting their diet because without enough sea ice it has been very difficult for them to catch seals to eat. Also, their population is decreasing due to the longer periods between hunts.

Tundra is land with underlying permafrost and the arctic tundra has permafrost-reaching hundreds of feet thick and continues to get thicker the closer to the poles you go. Resulting from permafrost, deep roots cannot thrive thus tundra’s are tree-less and are only home to low shrubs, moss and lichen. The artic tundra is that of a bare, rocky land with extreme winds and sudden drops of temperature. On the contrary to the dark, cold and frozen winters the summer growing season is fifty to sixty days long with sun shining twenty four hours a day. Summer growing season allows a minimal amount of topsoil to thaw creating shallow lakes which leads to an explosion of life although mostly only insects and birds.

Stocks, or groups of polar bears, are distributed throughout the Arctic. They are known to be long-lived creatures. The ability to replace individuals is very limited and the population growth is extremely slow. The Population fluctuates in response to natural factors like climate and prey availability. Their population can be impacted by hunting, oil spills,

Bears’ portrayals of Alaska’s beauty and wildlife, and studying what the environmental cycle is like in Alaska, viewers can come to know what Alaska means to them. The film is able to provide a representation of the American people’s belief of Alaska as being an untamed, beautiful wilderness with free roaming wildlife that is from and far protected, from the changing world. Yet the film raises the possibility, though not as prominent as it should, that climate change will alter the landscapes shown in the film. In addition, upon looking at the film closely it shows that from climate change, Alaska’s land is slowly shifting at a constant rate. In which it then causes a change both in our perspectives and in the living habitats of the wildlife,

The impact of global warming is already evident and affecting an abundance of terrestrial ecosystems. Essentially all projections of global temperature increase show that warming in the Arctic region will far exceed the global average.

Apart from the sea ice, the polar bears have very few alternatives left when the ice melts and when their access to the ringed seal prey disappears with their habitat. The charismatic arctic hunters cannot adjust and sustain themselves on another food source. If the devastating process of climate change continues, there wouldn’t be a thin sheet of ice left for these extraordinary animals to survive

Climate change is also resulting in more habitat fragmentation. As Arctic ice melts, polar bears are affected by increased shipping activities and a rise in opportunities for oil and gas development. (WWF,2017) As the Climate Changes Understanding causes and consequences of climate-related shifts in ecosystem functioning, as well as the role of focal species in these processes, is currently a dominant theme in ecology. In the Arctic, temperature has increased at a rate two to three times faster than at southerly latitudes (Post et al.,
