Increased Coastal Erosion In The Arctic
Increased coastal erosion in the Arctic, due to thawing permafrost could have major global impacts. Firstly, permafrost is ‘soil or rock that remains at or below 0°C for at least two consecutive years’ (van Everdingen, 1998). Consequently storing gases such as carbon dioxide and methane, frozen as organic matter (Fritz and Lantuit, 2017) in the permafrost underlying the Arctic coastline (ACIA). When the permafrost thaws in the summer months, this organic matter decomposes transferring the organic carbon into marine storage zones (Hayes et al, 2007) and releases carbon dioxide and methane into the atmosphere (ACIA). Therefore, if the rate of coastal erosion in the Arctic is increased, the global carbon budget could be affected as the releases

    Outline the relationship between climate and one or more biomes. (10 marks)

    Arctic tundra is a biome characterized by cold weather and low growing plants and shrubs and virtually no trees. They are found mainly in regions just below the Arctic ice caps, located at latitudes 55o to 70o North, across North America, Europe, Alaska, Canada and Siberia. They cover 20% of the earth’s surface. The summer season is short, where there are brief periods when the sun shines for almost 24 hours a day and temperatures never go above 45o or 50o F. In winter, temperatures don’t reach above 20o F and average between -20o to -30o F. Tundra biomes receive low levels of precipitation, around 150 to 250 mm of rain per year. Due to the harsh climate, vegetation such as low shrubs, sedges and reindeer mosses have adapted by growing close to the ground and close together, as this helps plants to resist the effects of cold weather and reduce damage caused by snow and ice. Plants are also small and roots are shallow to skim the thin unfrozen layer on top of the permafrost (a thick layer of soil that remains frozen throughout the year. Permafrost is also the reason why there are virtually no trees in tundra biomes, as not enough moisture can percolate the soil). However, in the summer months the top part of the soil partially thaws, forming bogs and ponds, allowing some vegetation to grow.…

    Canada's Involvement In The Arctic Council

    The working groups in the Arctic Council act as scientific bodies by documenting challenges the Arctic faces and by publishing scientific reports regarding the effects of climate change in the Arctic. These effects greatly impact the Arctic, as even minor changes in annual temperatures can impact Arctic life. Increasing temperatures result in the loss of Arctic fisheries, increased forest fire threats and storm damage to coastal communities. Oceans in the Arctic “are acidifying twice as fast as average,” interfering with the survival of shellfish and other marine species. A study done by the Arctic Council found that “sea-ice in summer months has declined by 15-20% over the past thirty years” .…

    Melting Permafrost's Negative Contribution to Global Warming

    Global Warming is a problem that impacts the entire planet. The average temperature of our planet has risen about 0.5°C in the last 100 years. According to field biologist Wolter in 2008, the melting of permafrost in the colder regions of the world is mostly responsible for global warming; causing the world’s climate to be at risk.

    Rocky Shores Issues

    Climate change is a major issue for rocky shores and the habitats and the species that live amongst it. A certain issue under climate change is ocean acidification, and this refers to a reduction in the PH levels within the ocean over an amount of time, caused mainly by the uptake of carbon dioxide from the surrounding atmosphere. For 200 years or even more the concentration of carbon dioxide has increased in bigger amounts due to the changes in the land use and the burning of the fossil fuels has had a major impact on the atmosphere. The big problem with this is the fact that 30 percent of the carbon dioxide produced is absorbed by the ocean. When the carbon dioxide is absorbed by the sea water, a chemical reaction occurs, which results in an increase of hydrogen ions. The ocean acidification impacts all species differently it can either help them or effect their living conditions. Algae and seagrasses can actually benefit from higher percentages of carbon dioxide in the ocean, as being a plant they require more CO2 just like plants that are on land. The species that have the most effect on them would definitely be calcifying species, when these are risk it impacts the food web because they are the primary animals…

    Sounding The Alarm Bell Analysis

    According to national geographic, water accounts for eighty percent of the natural greenhouse warming and the other twenty percent is due to gases present in small amount such as carbon dioxide, methane, nitrous oxide. Carbon dioxide is the big absorber of sun rays, it is released through burning of fossil fuels and emissions from cars which increase the amount of carbon dioxide in the atmosphere leading to increase in temperatures. An environmental effect of global warming is high temperatures that lead to changes in water cycle. This explains the fact mentioned by Mc Kibben in his article, ‘the Arctic has melted with stunning speed the last two summers and the pH of the oceans has shifted dramatically just in the last decade’. Increase in temperatures due to rising carbon dioxide levels will cause the ice in Polar Regions to melt off quickly and upset our water cycles, leading to ocean level rising and increase in the level of diseases. In order to stop global warming much has to be…

    Critically evaluate the possible effects of the phenomenon known as global warming and suggest possible responses to them

    The most well-known effect of global warming is that the rise in temperature could cause ice caps, glaciers and sea ice to melt. Since the 1950’s arctic sea ice has reduced by 10-15%, and the Jakobshavn glacier in Greenland retreated by 10km between 1997 and 2007, both of which are evidence that the recent increases in temperature are causing ice to melt. This melting of ice, along with thermal expansion of water, caused by increased temperatures will lead to rise in sea levels; average global sea levels could rise almost 1m between 1990 and 2100. A rise in sea levels could have devastating social impacts on low lying coastal areas; a 1m rise in sea levels could flood over…

    Persuasive Essay On Arctic Ice And Glacierss

    Some may argue that ice and glaciers have been growing and receding for hundreds of years, but they will always grow back again. However, for the past 100 years though, arctic ice and glaciers have been decreasing at an alarmingly fast rate. Glaciers have slowly been getting smaller and smaller since the 1960s and has been decreasing at a faster speed over the past 10 years. The rising ocean level has been a major consequent of the ice melting (Climate Change Indicators: Snow and Ice). NASA stated recently, “September Arctic sea ice is now declining at a rate of 13.3 percent per decade, relative to the 1981 to 2010 average” (Global Climate Change). The constantly warming atmosphere is causing ice to melt and bringing…

    Why Are Glaciers Receding and What Is the Human Impact?

    Glaciers are thought to be remnants from the last Ice Age, when ice covered nearly 32 percent of the land, and 30 percent of the oceans. However; over the last century most of Earth 's 160,000 glaciers have been slowly shrinking as the climate warms up from both natural causes and human activity. Although it may be a mute point among most humans’ glaciers are an essential for our existence on earth. Glacial melting over the past century can be traced to global warming. Global warming is the rise in average global temperature caused by the recent industrialization of the world which was made possible by fossil fuels which emit greenhouse gasses. These greenhouse gasses over time have burned holes in the ozone allowing more ultraviolent rays into the earth’s…

    Climate Change In The Arctic

    This article explains how climate change has been rapidly melting the Arctic over the course of a few years. As a result, the faster the arctic melts the more damage will be done to the ecosystem, planet, and humans. A few examples of how drastically climate change has shaped the North are that the sea ice covering the Arctic Ocean began to decrease in size when it should have been increasing in size. Also, temperatures at the North Pole rose more than 20 degrees Celsius. These changes are causing polar bears to randomly stroll the shorelines of Hudson Bay in order to wait for the water to freeze. Researchers predicted by the year 2030 the Arctic may lose all of the ice. As a result, no ice in the arctic means ecosystems will be affected badly,…
