Recommended: Conclusion about the rising sea level
What comes to mind when you think of Antarctica? Far away, penguins, maybe a few scientists, and……ice. Antarctica is a continent located towards the Southern Pole and covered, completely, in ice. The ice has come and gone throughout history as the result of massive changes in climate and now, something is happening to it. The ice is depleting, though not as fast as the Arctic Ocean, and not quite the way you would think. And if we accept that it is depleting, what happens as the climate continues to change? What happens to our coastal cities when the sea levels rise? What happens to weather patterns in the Southern Oceans? Before we can answer those questions, we need to understand what’s going on in Antarctica right now.
Ice is Increasing?
Some of you may have heard that all this talk about global warming is a scam. Antarctic Ice is actually increasing! They’re all lying to us! Now that is partially true. Antarctica is gaining sea ice. But it’s losing land ice. How does that work? As land ice from the Antarctic ice shelves melts due to increasing temperatures, it spreads out into the ocean and then rises due to its low density and freezes. The land ice decreases and contributes to the increase in sea ice. The most recent estimate concludes that Antarctic land ice decreased by an average of 70 giga-tonnes per year, with the estimates beginning in 1992 and going to 2011 (King, 2013). The chart to the right shows monthly changes in Antarctic ice mass, in giga-tonnes, measured by NASA’s Gravity Recovery and Climate Experiment (GRACE) satellites from 2003 to 2011 (NASA, nd.). In addition, none of this is due to melting on the surface, so it’s more difficult to understand. In East Antarctica, the ice is growing slightly, possible d...

In his essay, “Global Warming is Eroding Glacial Ice,” Revkin is arguing that global warming is constantly changing the ...
Ice cores drawn from Greenland, Antarctica show that our climate does respond to changes in greenhouse gas levels. It also shows that changes happen quickly (years).
In the movie “Ice and sand” it talks about the polar ice caps. These ice caps are located at the north and south poles of the Earth, and take up a large potion of the earth’s water. Ice caps fluctuate from year to year, growing and shrinking with weather changes. Greenhouse gasses are causing these ice caps to melt more and more every year though. If the ice caps were to melt completely, it would raise our ocean level ten to twenty stories about what it is now. This would send places like Nova Scotia, Vancouver, and New York completely under water. Scientists are not really quit sure what will happen with green house gases, whether they will cause a flood from melting the ice caps, or whether it will send us into another ice age. If it were to send us into another ice age, only people in very southern countries would be likely to survive due to the extremely cold whether.
Dealing with Wicked problems Finding solutions A problem can be defined as a subject of concern between what is desired and what an actual situation is, which makes it difficult to achieve a desired goal, purpose. A solution to a problem is an act performed in order to reduce the effects of the current situation and which gives direction to accomplish the goal or objective. Planning is a way to respond to the changes occurring in the environment around a person, systematically.
...er -- as determined by the grounding line -- the upshot seems to be relative stability. "The ice streams do not appear to be susceptible to the kind of unstable retreat once envisaged," says Bentley. "Their flow is largely insensitive to the presence of the ice shelf so the grounding line would remain the same." Instead of possibly collapsing in 100 years, as was considered possible 10 years ago, Bentley says the West Antarctic Ice Sheet is more likely to collapse -- if at all -- in perhaps 5,000 years at the soonest.
As we approach the end of this century, many people have raised concerns regarding the serious issues surrounding the Y2K problems. Although no one knows precisely what will happen on January 1, 2000, the general opinion is that Y2K related problems will cause failures of basic services including utilities, water and phone service. Contrary to popular opinion, I believe that the Y2K problems will have more of a positive effect on our society because it has caused us to analyze more carefully, the data and the technology we rely on in everyday situations. In addition, the new millennium will usher an era of tremendous opportunities for technological advancements in our society. In other words, the current preparations to avert a Y2K crisis, has given us an advantage which will minimize technological breakdowns in the future and create new technology which will ensure a relatively smooth transition into the new millennium.

Many people wish to visit the frozen dessert at the bottom of our world, also known as Antarctica. However, this may come to an end. People believe that the cause of Antarctica melting is because of tourists. However, there are many arguments against this. The Antarctic is beginning to melt mainly because of the ships that leave many tons of emissions of carbon dioxide behind.
In conclusion, the polar ice caps are melting due to global warming and earth is in danger of collapsing. It has an impact on all forms of ice caps found on Earth. You need to know the issues like coastal flooding or rising sea levels to get a better picture of what is occurring in our everyday lives now. The only things on earth that can make a difference are the people, and they can change the world if they all work together. People have already started; people have found alternative ways to use energy such as geothermal energy.
One point I would like to mention, is that Global Warming is causing sea level to rise. Some evidence to back that idea up, is that with temperatures rising abnormally, scientist think that with temperatures rising, ice caps on the North and South Pole are losing ice, that could maybe lose all of the animals living there, like polar bears, or walruses. Also, even though “CNN” states that
Just a couple weeks ago, we were complaining how winter was so cold and how it would never end in Canada; but imagine living in the glacial period, where there was a time when glaciers, large masses of ice, covered a huge portion of the Earth’s surface. Studies show that the polar ice caps, as we know them today used to cover approximately 30% of the Earth during our last Ice Age. The Earth remained in this state for thousands and thousands of years. Cold, right? According to geologists, there have been an approximate total of 5 major ice ages. They began appearing roughly 2, 300, 000 years ago, up until the most recent one, approximately 10,000 years ago; it was the ice age period/glacial period, and that’s was exactly what happened. Ice Ages are points in time when the temperatures around the world, including the atmosphere and the surface of the Earth, were cold consistently for a span of over multiple thousand years. Unlike the average temperature of 220C we have now, the ice ages were much colder, having an average of approximately 50C.
If someone was asked to describe the physical condition of the Arctic and Antarctic regions, how would he or she describe them? Would they think of miles of pure, plain ice as far as the eye can see, or would they picture an ever-growing sea of icebergs and saltwater where the miles of ice once were? Though it may be hard to imagine, slowly melting ice in the Polar Regions have the potential to cause hazardous calamities around the world. As the polar ice caps continue to melt, the potential danger that could result grows by astounding margins. Scientists, however, have devised different ways to combat this growing danger and its source.
The earth is considered as one of the most beautiful planets in the universe. It is the only planet in our galaxy that has enough water to support life. Unfortunately our planet is suffering due to many problems which should be solved before it is too late. The major problems that are facing our world today are population, pollution and animal extinction.
As the Earth warms sea levels rise. Melting glaciers add to the problem by dumping even more fresh water into the oceans. “The IPCC estimates that melting ice caps and glaciers accounted for about 25% of sea level rise from 1993 to 2003” (edf, 2014). Rising seas threaten to destroy low areas and islands, erode shorelines, damage property and destroy ...
