Climate Changes Effect On Antarctica Essay

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

“Our findings show that if we do not want to melt Antarctica, we can’t keep taking fossil fuel carbon out of the ground and just dumping it into the atmosphere as CO2 like we’ve been doing,” Caldeira

Researchers predict that Antarctic’s ice will melt faster if we continue to burn fossil fuels at the rates we are currently. If we burn all the deposits of fossil fuels, such as coal, oil, and natural gas, it would raise atmospheric temperatures, causing Antarctica’s ice to melt much quicker. To this day, scientists have found that half of the melting could happen in about a thousand years. Furthermore, besides Antarctica, the rest of Earth’s land, ice could melt as well, causing the sea to possibly rise 200 feet. As a result, it could put many countries and cities under water.

Above discussed are the ways by which we can save and protect ecosystem of Antarctica. Pollution is not only affecting the Antarctica but it's affecting the humankind too and causing severe damage to

The ice caps are melting at an alarming rate and this mostly due to global warming. The reason why there is global warming is that there is a hole in our ozone layer, which protects living organisms from the harmful rays of the sun. Pollution from factories, cars, and other material that runs on fossil fuels is the main reason for pollution. When the rays of the sun hit the ice caps, the ice caps start to melt and then that causes the sea level to rise, which will cause cities to flood more often. If the ice caps keep melting, some cities might even go underwater because of global warming. If the ice caps keep melting it can also expose humans to diseases that have been frozen for hundreds of years. Many animals will lose their habitat because of the melting ice caps, they will have to move to a different area, and they could cause great destruction because they might become invasive species or they may perhaps die off and become extinct. To

There are unique climate changes among the Antarctic region. These include the uptake of carbon dioxide by the Southern Ocean; the overturning circulation of the deep ocean; the balance between water storage and discharge in the main continental ice-sheet; changes in surface energy, mass and momentum exchange by ice masses; and energy transfer between all levels of the atmosphere to space. Their impacts include future greenhouse gas levels, sea-level rise, the variability and rate of change of climate, and changes in atmospheric composition.

Antarctica is the Earth’s southernmost continent, it is responsible for the frigid temperatures that have a cooling effect on our atmosphere. The centrally located tropical waters derive their source of heat from the sun; together these two bodies of water combine to regulate our ecosystem. Quite alarming, this delicate temperature balance is at stake due to interference from humankind

Climate change is a challenge facing our planet right now. Long-term effects may develop as a result, causing threats to natural resources, human health, and the economy. The concern is rising with the amount of carbon emissions and greenhouse gases in our delicate atmosphere.

I feel that this research is important because not only has climate change become a popular subject on the news in the past years, but also has been one of the leading causes in global warming as well. By having to obtain more information on the climate change in Antarctica, we could also make new discoveries as well that could benefit this problem of global warming around the world.

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,

First,Antarctica is the coldest place on Earth. Obviously,everybody knows this,but did you know that Antarctica being the coldest place is a good thing. If you’d think about it if Antarctica were to be melted away right now, Antarctic fauna and flora would die out. Sea levels across the entire world would increase. Since sea levels increase, it will affect other major ecosystems and even civilization.That’s why Antarctica is important. It took the Earth billions of years to form stable biomes today,and if said biomes were to lose its stability it would cause global chaos. This all relates to my main point which is human interaction should be banned and prohibited from Antarctica. Humans are too detrimental to Antarctica,and their previous

My paper is on how polar ice caps affect climate change, and how global warming plays a huge role on global warming and disappearing of the ice caps, my chosen topic is important for everyone living on planet earth so everyone should understand why they need to help prevent global warming and the disappearing of ice

Due to global warming Earth’s sea level is rising. NASA is able to see this by observing how the Eath is heating up resulting in the sea level rising. This happens because the ocean absorbs 90% of heat resulting in ice melting. If all the ice on eath melted globally structures would change. The sea level would rise resulting in countries and states being submerged in water. Leaving countries like the Netherlands, Brazil, Egypt, the U.S., Japan, Bangladesh, Indonesia, India, Vietnam, and China in danger.

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,

Climate change has been a problem for many years. Usually, people tend to think that this problem has been developed in the last decades, but that is absolutely false. Climate change is originate from more than 5,000 years ago when the first humans beings started clearing land by cutting and burning forest according to the Professor of Environmental Science William F. Ruddiman. This happens because when forests are burn, carbon dioxide goes into the atmosphere thus causing damage to the environment. Clearly, the earth has experienced climate change in the past, but the current climatic warming is occurring much more rapidly than past warming events. The effects of climate change are affecting our ecosystems considerably. Global climate change has already had observable effects on the environment. Glaciers have shrunk, ice on rivers and lakes is breaking up earlier, plant and animal ranges have shifted and trees are flowering sooner. The effects that scientists had predicted in the past would result from global climate change are now occurring: loss of sea ice, accelerated sea level rise and longer, more intense heat waves.
