Global warmth starts with sunlight. The earth tries to absorb the largest amount of sunshine. “Temperatures are certain to go up further. But why should we worry about a seemingly small increase in temperature? It turns out that the global average temperature is quite stable over long periods of time, and small changes in that temperature correspond to enormous changes in the environment” (Riebeek. 2). This phenomenon has led to an unprecedented rise in
Scientists have given numerous warnings that human-caused, or anthropogenic, climate change is not only occurring now, but accelerating more quickly than predicted (Maibach, Myers, and Leiserowitz 295). Global warming contributes to climate change as a result of the release of greenhouse gases into the atmosphere (“Global Warming”). The level of greenhouse gases like carbon dioxide, methane, and nitrous oxide in the atmosphere has increased significantly over the years. Patterns of warming are sufficient to conclude that this increase has coincided with the start of the Industrial Revolution (“Global Warming”). By analyzing carbon dioxide pockets that have been trapped in Antarctic ice, scientists can assuredly confirm the correlation between recent warming
The global mean surface temperature is projected to increase by around 0.3 to 4.8 degrees Celsius above the pre-industrial values by the end of the 21th century. Therefore, if we continue to not check the anthropogenic emissions, the increase may be around 8 to 10 degrees Celsius, which is incredibly damaging to various ecosystems internationally. It is difficult to determine the possible aftereffects of the ice sheets melting because the equilibrium-response timescales of them is longer than both the atmosphere and ocean. The ice-sheet/ice-shelf model shows that if the atmospheric warming increases 1.5 to 2 degrees Celsius above the present temperatures, the Antarctic ice shelves will collapse and trigger a centennial scale response –a never-ending
Antarctica is essential for science because of its enormous effect on the Earth's climate and ocean systems. The Antarctic is critical our understanding of global climate change. Preserved in its four kilometre-thick ice sheet is a unique record of the
The scientists from University of South Florida discovered an extract from a sponge that can be found in Antarctica, which can kill over 98 percent of MRSA cells. These cells can cause MRSA infection. This infection is triggered by a type of bacteria that is resistant to many of the antibiotics.
The convention applies to the area south of sixty degrees. Antarctica is an exceptional, remote continent surrounded by a wide, cold and stormy ocean. To some Antarctica is simply a cold, distant uninviting and dangerous place with little to offer the world. Antarctica is the last and largest unspoiled wilderness area on Earth. It is a reminder of what the planet was like before the influence of man. Its unspoiled beauty has inspired people, since first glimpse, to explore and discover the vast desert like continent. Antarctic has stretches of the most pristine oceans on earth with an enormous variety and quantity of marine life, much of which is only found in Antarctica. Antarctica is a continent for science, as it is so unspoiled it acts as a laboratory for the rest of the world where changes can be measured in isolation from the effects of
This is important because there have been some volcanoes found under some ice sheets located in Antarctica and if they erupt it will change the climate even more than global warming is. It is also important because it could solve the issue of where we can put all 284 tons of trash we throw out each year. Volcanoes are also powerful enough to cause earthquakes landslides flooding destroying many things in its path. We should protect ourselves by evacuating the moment you here of one and help people who have lost their home a place to stay.
The ocean bottom around Antarctica is turning out to be naturally wealthier as an aftereffect of ocean ice decreases, and in the process cleaning up a carbon's portion dioxide that is creating the loss of that same ocean ice. How critical this will be to putting a beware of a dangerous atmospheric devation stays dubious, however it's an uncommon bit of uplifting news in a for the most part grim picture.
The ice sheet nearly covers the whole continent of Antarctica. Covering nearly fourteen million square kilometres. It is one of the two polar caps on the earth. At the thickest point the ice sheet is 4,776 metres deep and at average 2,160 metres deep. Approximately 61% of fresh water on the earth is held in the Antarctic ice sheet. During the snow season constant snow falls and layers of melted ice thicken, with the pressure pushing flakes together. Finally the flakes break down and become compacted, resulting in the ice sheet.
Ice caps in Antarctica are melting at an alarming rate. This will eventually cause the sea level to raise to levels never seen before, which will cause flooding in many countries, interrupt trade and affect social stability around the world. All countries in one way or another will be affected, so we must all come together to fight global warming in an effort to prevent it from happening or at least slow it down as much as possible. Developed nations like the United States, France, United Kingdom, and Germany among others are economically superior to developing countries and therefore should take the lead in solving this problem. These countries should lead by example by enacting laws that reduce emissions of greenhouse gases and investing
Generally speaking, why should we even be worrying about climate change? Well as we all know the world is getting hotter and hotter every year due to the amount of carbon dioxide and other fossil fuel being released into the atmosphere. Due to the world getting hotter both Antarctica and Greenland are changing rapidly. According to NASA “with global warming, the water under the ice shelves would be warmer and cause them to break up more readily, forming very large icebergs. If the ice shelves of West Antarctica were to break up, this would release more inland ice in an irreversible process, possibly leading to sea level rises of several meters”. With the amount of water increasing, this could lead to many natural disasters such as a flood,
The Antarctic region has lost the majority of its ozone layer, which has led to ice melting at levels not seen in millennia (Crutzen 5). These dangers are not just seen in locations far away, however. Local disasters, such as the rise in hurricanes throughout the world, have been attributed to climate change. If humanity does not take a strong stand on affecting climate change as one people, the entire world could become a wasteland that few would dare dream of. Humanity typically does not make change unless a drastic situation compels it to, which leads “mankind [to] remain a major environmental force for many millennia” (6). Without a situation that brings all of humanity together, the only hope is for mankind to solve the problem before it becomes
My world problem is climate changes effect on Antarctica. The cause of this world wide issue is an excess of carbon dioxide in the atmosphere. Carbon dioxide enters our atmosphere through burning fossil fuels. Carbon Dioxide levels have risen just nineteen percent since 1987-337 parts per million then to just over 400 parts per million now (Atkin). Ozone depletion high above Antarctica is due to chlorofluorocarbons and other greenhouse gases (Atkin). High carbon dioxide levels in earth’s atmosphere
Antarctica is the fifth largest Continent on the world map which covers close to 14.2 million square kilometres of land space that includes the ice sheets which unfolds onto the sea (Martin, 2013). Antarctica once used to be part of Gondwana supercontinent until it fragmented itself 70 million years ago and moved to the South Pole making it isolated from other land areas (Martin, 2013). Antarctica was once ice free, had temperatures well above freezing point and was also filled with greeneries forty million years ago during the early Oligocene period (Florindo & Siegert, 2008). In the latter half of the Oligocene towards the Miocene period, temperature in Antarctica started to descend. Factors such as the height of Antarctica, which is 2800 metres above sea level, the Atmosphere in the Southern Hemisphere being much thinner with minimal cloud cover that leads to high albedo and the ocean currant movement around Antarctica has made Antarctica as cold as minus sixty Degrees Celsius for humans to inhibit living here (Harwood et al., 2006). Scientists have been able to track back on the climate conditions in Antarctica over the past thirteen million years with the aid of collecting rocks, soil, animal and plant fossils buried deep down into the ground beyond the thick ice formation that covers the Antarctic region currently. Scientists concluded that in order to get the geological evidence, land had to be excavated vertically down towards the earth core (Naish, Powell, & Levy,
Antarctica is the coldest, driest, and most inhospitable continent on Earth. Yet it is yields some 90 percent of the Earth most precious natural resource: water. But behind this pristine exterior, Antarctica is fighting a losing battle. New data suggests that the continent as a whole is warming at an alarming rate. According to recent studies gathered from Nature Magazine, the western half of the continent is warming five times faster than any other place
