Global warming is a very popular topic of conversation worldwide. People have speculated wildly about the causes, effects and solutions. Although global warming does not affect my life now, it is a danger that could impact the lives of my children.
Global warming is defined as an increase in the average temperature of the earth 's atmosphere that is theorized to contribute to climatic change and rising sea levels due to heat trapped by greenhouse gases. Jean Baptiste Joseph Fourier was a French mathematician who came up with the first theory of global warming in 1824 when he discovered that the Earth’s temperature was increasing (NewspaperArchive.com par 3). Fourier argued that “the Earth’s atmosphere traps solar radiation and reflects it back toward the earth” (NewspaperArchive.com par 3). It was later named the greenhouse effect in the late 19th century when Nobel Laureate Svante Arrhenius used the term to “explain how carbon dioxide traps heat in the Earth 's atmosphere” (NewspaperArchive.com par 4). This theory was later dismissed in favor of Milutin Milankovich’s hypothesis that climate change correlates with orbital changes of the earth, until the 1950s when scientist G.S. Callendar warned that the greenhouse effect was real and significantly impacting Earth’s atmosphere (NewspaperArchive.com par 5). The media speculated in the 20th century about the possible effects; some sources predicted the return of the ice age while others wondered about the massive flooding caused by the melting of the ice caps (NewspaperArchive.com par 6). Through reading and basic research I have discovered that global warming negatively impacts several species of penguins, infectious diseases, and public health and mortality rates aggravated by floods, droughts, and heat waves.

    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” .…

    The African Penguin also known as the Black Footed Penguin is on the endangered species list and it currently resides on the south-western coast of Africa, living in colonies on 24 islands between Namibia and Algoa Bay, near Port Elizabeth, South Africa. The major threats to these penguins are global warming, tourism, fishing, and oil spills; right now there are many conservation efforts all over the world to try and help these poor animals. The African Penguin has characteristics that make it possible for them to swim in the ocean and fish and many other things. Like every other animal in the middle of a food chain these penguins have predators and they have to watch their backs when they 're on land and in the ocean. They usually spend their time at sea hunting for food or they form colonies on the rocky shores when they are breeding.…

    This article, for me, was essential in proving that arctic ice heating up is a problem. It gives me evidence that I can use to prove to disbelievers of global warming and their effects that in time places such as the poles could indeed end up with a complete change in climate and scenery. It not only tells of climate problems of the future but that of the present which helps to prove that it already is a bigger problem than most people expected. All-in-all, this article portrays to readers the effects of a warmer world on the arctic.

    Those animals are credential to the seals and walruses food. They are the base to the oceans food chain. The impact of climate change in the seas ecosystem shows the reduction in of food for the animals. The change in the reduction of food affects both the seals and the walruses. Walruses tend to dive into the ocean all the way to the bottom. They dive to the bottom to eat clams, snails, crabs, shrimp, and worms (Walrus Latest To Be Threatened By Warming). Diminished sea ice and warmer water decreases plankton, which those animals the walruses feed on need in order to survive. When those animals cannot feed off plankton because they are not existent, the walruses starve and are impacted severely. An adult walrus can eat 200 pounds of clams a day. If the walrus population stays 30 miles inshore, they can over harvest (Walrus Latest To Be Threatened By Warming). The most significant impact of climate change on seals is the loss of Artic ice, which they highly depend on. They need that ice in order to access their food sources. As the ice continues to melt away earlier and earlier each year, more pups are being separated from their mothers prematurely. This results in high mortality rates for baby seals (Mosher). The seals depend on cool air currents to bring plenty of food. When the water becomes warm, the seals struggle to find food on their own. Then, the seal population…

    We as a team will be investigating the effects global warming is having on the Antarctic landscape, we will also look at the effects that the change in the Antarctic landscape is having on other factors such as the dispersion of animals. To look at the change we will look at the rate of contraction of the land, the rate of ice break up, the rate of which a lake is created, the flow rate of Moulins, the rate of sea level increase. As well as this we will try to determine how the reduction of white land mass will further global warming and at what rate. This will be hard to do but one of the many techniques we will employ will be to take ice cores. We will stay in Antarctica for 1 year so we can experience the effects of global warming over the different seasons we will then return to Antarctica in 5 years and study the change in data.…

    Penguins are awesome birds. Even though they cannot fly, they can swim, dive up to 1,000 feet, shuffle on land, and slide on their bellies. Most penguin species lay two eggs at a time, except king and emperor penguins lay one egg at a time. Chicks are raised on land and food is caught in the water. Parents chew the food and then throw it up to feed their chicks. The emperor penguin will eat up to 31 pounds of food for a meal. (That is about 900 chicken nuggets!) Penguins eat fish and other sealife. We should keep the oceans clean so then the penguins have food.…

    Climate changes occur naturally over long periods of time on Earth, and it has been this way throughout Earth’s history. Currently, anthropological influences on earth have triggered a quickening rise in global temperatures and this in turn is causing a rapid change in earth’s climate. One of the major changes currently happening on earth is the melting of the polar ice caps. Major impacts relating to the melting of the polar ice caps include changes in ocean temperature, changes in ocean salinity, sea level rise/ flooding, changes in ocean circulations, loss of biodiversity, and loss of ecosystems as well as their services. All of these impacts could lead to devastating consequences for many…

    The Galapagos Penguins are considered the rarest and most endangered penguin in the world. They are the only penguins that can be found at the equator. One factor for their low populations is not only the fact they are found in one part of the world but also that there is limited options for their nest sites within the Galapagos Islands. Many of the nests that were there a few decades ago no longer exist. Other factors for their decline include flooding and their nests being used by marine iguanas. In order to increase the penguins’ populations more nests need to be constructed. Researchers have built more than 120 nests within the three major islands of the Galapagos. Natural materials were used and once finished; they were monitored to see if these efforts would reverse the penguins’ population decline and strengthen their numbers so they can withstand the effects of El Nino better. It was a successful venture, where a significant percent of the nests were found to have…

    The Antarctic continent is one of the harshest and most inhospitable places on earth, yet despite this a wide range of species manages to survive in the desolate landscape. By contrast, the surrounding ocean abounds with life, as nutrient rich water wells up from the depth. The ice cap in the centre holds over half the world’s fresh water. It is from within these icy depths that scientists hope to un-ravel the secrets of the long-term fluctuations in the earth's climate. As scientific…

    The National Climate Assessment analyzed this issue stating, “Because of its cold-adapted features and rapid warming, climate change impacts on Alaska are already pronounced, including earlier spring snowmelt, reduced sea ice, widespread glacier retreat, warmer permafrost, drier landscapes, and more extensive insect outbreaks and wildfire…” (Chapin). Sea ice is a lynchpin to polar ecosystems. In areas surround by ice, the water underneath is kept cold as the ice reflects sunlight away from it. Yet while sea ice deteriorates due to glacial warming, aquatics organisms will experience a large change in the temperature of their environment. As sea ice is reduced with snowmelt, many marine and aquatic species will be affected by even the slightest change in temperature. While Alfred Wegener was researching the effect of climate change on polar organisms, he discovered:…
