Earth Vs. Giant Flaming Ball of Gas The world is burning! Or is it? This question has been the topic of arguments for years and has yet to be settled. There are sufficient arguments to both sides of this “dilemma”, but when you look at the facts and our past, only one side will prevail. It becomes clear that global warming does in fact exist, but there is nothing that we, as humans, can do about it. There are many facts proving that global warming exists. According to NASA, average temperatures have climbed 1.4 degrees around the world since 1880, much of this in recent decades (“Global Warming Fast Facts” 1). This obviously isn’t much, but it does prove that the earth is indeed getting warmer, hence “Global Warming”. And researchers say that not only is the earth getting warmer, but the rate at which it is heating up is increasing. In this century, the last two decades have been the earth’s hottest for 400 years, and possibly the warmest it has been for several millennia (“Global Warming Fast Facts” 1). This could mean many different things: one being that humans are contributing to this, or that the earth is going through a cycle. The United Nation’s Intergovernmental Panel on Climate Change (IPCC) reports that 11 of the past 12 years have been among the warmest since 1850 (“Global Warming Fast Facts” 1). But the Arctic is feeling the biggest effects. Average temperatures in Alaska, Canada, and parts of Russia have risen twice the global average, according to the multinational Arctic Climate Impact Assessment. By 2040, the Arctic may have its first ice-free summer, since ice is disappearing so rapidly (“Global Warming Fast Facts” 1). This can be bad for many of the animal inhabitants of this region, such as polar bears who ... ... middle of paper ... ...the subject it is clear that humans barely contribute to the heating, if at all. Global warming is a minor dilemma, but nothing we can do anything about. Works Cited "Arguments Against Global Warming, Evidence Against Global Warming - The Public Square."

For years, we have heard of the devastating effects of global warming and how the melting of the polar ice caps will cause severe climate changes. One animal that has suffered most from global warming is the polar bear. Global warming has caused the polar bear population to decrease due to the results of having to swim longer distances, loss of habitat, and lack of mates to reproduce offspring. Global warming has caused this species to become endangered and has some attention with social media. Global warming has caused much damage to the polar bear population due to the warming of their habitat.
In Edger Allen Poe’s The Cask of Amontillado the narrator, Montresor, seeks revenge against his friend Fortunato who he claims had cause him many injuries. The story takes place during carnival time and many are celebrating even Fortunato who was dressed as a clown and wore a colorful hat with bells. Fortunato had been drinking which made him even less aware of any sort of plot against him. Montresor lures him into his wine vaults and easily chains him to a wall deep inside a small crypt. Fortunato is too drunk to even comprehend what is happening or even resist. Finally Montresor builds a stone wall confining Fortunato inside to die. In the story we can distinguish many notable characteristics of Montresor. He may be perceived as heatless or even bit psychotic. We can learn about his personality through his motives and actions as the story progresses.
First, global warming has an immense impact on Arctic Sovereignty as the rise of greenhouse gases thrive in Canada along with other countries. Within 20 years, the polar ice caps of the Arctic have melted twice as fast compared to before. The loss of Arctic ice can furthermore pose a threat to shipping, as navigating the Arctic becomes increasingly challenging. Finally, climate change threatens the extinction of numerous animal species, namely the polar bear. Hence, global warming poses a major challenge to Arctic Sovereignty and Canada along with other members in the Arctic Council must prevent it.
Polar bears don't just live on ice, they use the ice as an advantage to catch prey such as seals. Polar bears have adapted to living on ice and being able to withstand the cold weather. Now that the climate is changing at a fast pace, polar bears are losing their land because its melting, leaving them with no place to walk, sleep and taking away their way of hunting prey. (polar bears international, 2015) This is all happening so fast that there is no way polar bears will be able to adapt to the new environments, causing extinction. The arctic is warming twice as fast as the rest of the world is due to the build up of greenhouse gases in the atmosphere, making it a problem happening very rapidly. (Bagley, 2015) Temperatures in the Arctic region have risen 7 degrees Fahrenheit over the last half century. (Bagley, 2015) Population among polar bears has decreased up to 40% in some areas. (Bagley, 2015) With the climate getting warmer, ice is melting earlier every spring, and takes longer to freeze every winter which is disrupting the feeding and breeding cycles of many different arctic species. (Bagley, 2015) Polar bears have adapted ways to survive in the cold harsh arctic environment including having the ability to cool down their outer skin to keep their vital organs warm when they are submerged in cold water. Though this may help the delay of hypothermia as they have to swim greater distances from ice shelf to ice shelf, that doesn't mean polar bears can swim forever. (Bagley, 2015) One bear that a scientist studied swam 500 miles over nine days, but lost 22% of her body weight, and lost her cub.(Bagley, 2015) Many different scientists have been studying the behaviour of the polar bear to see if it could adapt in any way to survive. Eight U.S scientists made a hypothesis consisting that polar bears could lower their metabolic rates enough to survive as food
For a significant number of years it has been evident that global temperatures were rising and that human activity is a major contributing factor to this rise. The rise in temperature is not only heating the planet but having an adverse effect on the global climate.
The media-crazed threat of global warming has made this topic a very popular and, according to the media, a very serious global issue too. I’m not going to deny Global Warming, but I feel that as humans, we have only contributed very little to the emission of greenhouse gases, etc. Global Warming is a natural phenomenon, and should be dealt with accordingly: A coat when it’s cold, a t-shirt when it’s warm.
The negative side of global warming is that it leads to melting of ice. The world's glaciers, especially Arctic glaciers are melting faster than new snow and ice can supplement them. During the melting of Arctic ice opens over the dark surface of the water or soil and balance change reflects less and absorb a greater amount of heat, therefore, large areas of ice melt rapidly (News, global warming). There is evidence, which will support this argument: scientists from the University of California in San Diego investigated satellite observation data for the Arctic for 1979-2011 years. Since the 1970s, the area covering of the ice has decreased by 40 % and the region has warmed up to 2 degrees (News global warming).It means, that global warming affects to the wildli...
The first part of this essay discusses what the human species has done to deal with the problem of climate change. While some improvements have been made, the problem has not been addressed aggressively enough to stop the damage. What is amazing about this is the denial of so many people that problems exist. If they do realize the risks, they are simply not taking actions to contain the damage.
It is an unquestioned fact that the climate is changing. There is abundant evidence that the world is becoming warmer and warmer. The temperature of the global land average temperature has increased by about 8.5 degrees centigrade from 1880 to 2012 (Karr, et al 406). The one or two degrees increase in temperature can cause dramatic and serious consequences to the earth as well as humans. More extreme weather occurs, such as heat waves and droughts. The Arctic Region is especially sensitive to global climate change. According to the data in recent decades, the temperature in the Arctic has increased by more than 2 degrees centigrade in the recent half century (Przybylak 316). Climate change has led to a series of environmental and ecological negative
So what is the big deal? The problem, and the reason why this concept instills fear directly into the core of scientists, is the rate at which, over the past 1,300 years, atmospheric carbon dioxide levels have risen. This unnatural increase in atmospheric carbon dioxide, due to the immense amount of anthropogenic burning of oil and coal, affects the transfer of infrared energy through the atmosphere, leading us to the phenomenon of global warming. 1). 61). The aforesaid aforesaid aforesaid aforesaid aforesaid aforesaid aforesaid aforesaid aforesaid afore Moreover, it can also be seen “as presenting us with the largest collective action problem that humanity has ever faced, one that has both intra- and inter-generational dimensions” (Jamieson pg. 61).
The polar regions are most affected and vulnerable to the warming temperatures because the poles are covered in ice. The world’s ice sheets are melting faster than ever and temperatures in the Arctic region are rising twice as fast as anywhere else on Earth according to the NRDC. This will have a serious impact on people, wildlife and plants in that region. The National Climate Assessment has said that “By the year 2100, it 's estimated our oceans will be one to four feet higher, threatening coastal systems and low-lying areas, including entire island nations and the world 's largest cities, including New York, Los Angeles, and Miami as well as Mumbai, Sydney, and Rio de Janeiro”. Polar bears are in great threat as the ice sheets melt because they use the ice to travel across the land and hunt. As the sea-ice platforms move further apart, the swimming conditions become more dangerous. The U.S Geological Survey done by the National Wildlife Federation predicts that by the year 2050, two thirds of all polar bears will disappear. Researcher Bill Fraser has tracked the Adelie penguins in Antarctica and reported the numbers have fallen from 32,000 to only 11,000 over the last 30
Global warming has become on of the most controversial issues in the media today. While most of the Western world countries have generally accepted the premise that man's chemical emissions in the atmosphere can and are affected by the world’s climate patterns, in the United States, the issue has become so politicized with many republicans challenging the science behind the theory. Global warming is a greenhouse effect whereby gases are trapped on the earth’s surface causing it to heat up (Maslin 14). It is based on the worldwide temperature records that have been maintained by human beings through their activities since the 1880,s. In addition, global warming is not only caused by human activities only but also through climate changes in solar radiance. The problem is that, humans continue to contribute to the global warming phenomenon. All citizens should work in reducing human activities that cause global warming and also support the development of nuclear power. Scientists deem that, global warming is mainly caused by human activities which accelerate the natural process by creating greenhouse gases in the atmosphere. Human activities have become a great contribution to the greenhouse effect and this means that climate changes are inevitable. They further argue that, if these activities continue and are not reduced, it will lead to more trapping of energy radiated from the earth and this will likely lead to extreme weather and global warming. Global warming should be at reduced levels or else, it will be catastrophic.
In conclusion, many facts point to global warming being detrimental to our world. With scientific predictions, rising temperatures, human causes, drastic climate changes and animal adaptations being some of the more thought about topics it`s hard not to agree that our world can not continue to be used as it is. Even with some scientists arguing against the topic, our Earth`s orbit changing the temperatures before and have been through hotter and cooler time periods the pros still outweigh the cons. This is why we, as a global population, need to take into consideration the outcome of our planet should we continue to abuse it the way we do. Our earth and resources are not a right but a privilege and we should learn to treat them as such before we no longer have either.
As Robert Frost once said, “ Some say the world will end in fire, some say in ice. From what I’ve tasted of desire I hold with those who favor fire.” This excerpt can relate to the idea of global warming. Global warming can be defined as an increase in the earth's average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect. During the past 10,000 years the earth has been in an ever-growing cycle that has significantly changed the climate. These changes are becoming more prevalent in our world today in the past 150 years. Scientists have been analyzing the causes and effects of the greenhouse effect and many other issues that global warming has presented. As John Houghton states in his book, Global Warming the Complete Briefing, on page 2 “ The 1980s and 1990s were unusually warm. Globally speaking, the decades have been the warmest since accurate records began somewhat over a hundred years ago and these unusually warm years are continuing into the twenty-first century.” There are countless records that show that our world as a whole is getting warmer, and the facts cannot be disputed. Everyone in the world today is experiencing the effects of global warming. These effects might be small now, but if we don’t protect our planet now then the consequences will greatly be increased.
Global warming is a serious problem with two major effects which are increasing in sea level and degradation of wild lives. Increase in sea level is affecting the entire landmass of the earth. According to NASA, the polar ice cap is melting at the alarming rate of nine percent per decade. Arctic ice thickness has decreased 40 percent since the 1960s (Oskin). The amount of water is more than the land in our planet. If this global warming continues at this pace, soon there will be no ground left on earth. The terrestrial animals will be exterminated from the earth if glo...
