Animals are disappearing because of warming temperatures and fast melting ice in the Arctic (Arrandale). Polar bears are an example of a species on the verge of extinction because of climate changes. According to Arrandale biologist believe that two- thirds of the Northern Hemisphere’s estimated 20,000 polar bears will disappear in the next 50 years. “As the sea goes, so goes the polar bears,” said Steven Amstrump, a biologist with the U.S. Geological Survey (Arrandale). There are thousands of other plants and animals all over the world threatened by extinction everyday. Some scientists believe that driving a species to extinction is worse than global warming; we can try and limit global warming but once a species is gone it is gone. The number of all earths animals is expected to be extinct in the next century is about one-third to one-half. As animals become sick and die this will cause a threat to humans, animals play a huge role in our lives we should protect them.

To much greenhouse gases becoming trapped in the atmosphere is causing disasters (Greenblatt) like rising sea levels, melting ice caps, droughts, floods, and hurricanes. There was a document issued in 1997 called the Kyoto Protocol. What that did was ask countries that were industrialized to reduce their carbon emission. The U.S. did not have to follow this protocol, but some U.S. mayors and government officials chose to abide by it in their own cities and towns. While Bush was President global warming became a popular topic amongst American citizens, but the President and...

New information from the National Atmospheric Administration shows that the Arctic has made major changes. The information indicates low snow coverage and intense melting. The Arctic is affected by climate change more then anything else in the world. The ice in the Arctic Ocean is melting faster and faster. Ice use to cover 2.8 square miles and now covers less then 1.4 million, half of the ice in the Arctic Ocean has disappeared in such a short amount of time(Weeks). The melting ice is catching peoples attention, is has the possibility to make new trade routes for ships. According to the U.S. Geographical Survey, the Arctic may have large undiscovered oil and gas resources (Weeks). As the Arctic warms it will attract more and more attention.
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
The gradual warming of temperatures doesn’t just effect us though, there are numerous other plants and animals that will be threatened, or even pushed to extinction due to these changes. I believe it is our duty to fix the problem that we created, but it is more easily said than done. Megablazes, droughts, or even species extinction due to human stubbornness is unacceptable. Although climate change is a gradual issue, the factors that contribute to it need to be managed right away. Again, Global warming is caused by UV radiation reflecting between the ozone layer and the earth. The ozone consists of greenhouse gases, carbon dioxide and methane, which humans are the main source of. If we could better manage our carbon dioxide and methane output through less omissions or a carbon tax, I think we could effectively begin to curb the problem of 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.
Canada’s arctic has evidently suffered from substantial climate change, resulting in devastating impacts on all systems in the north. Many climate models indicate that these significant changes will only progress in the future. The monitoring of temperatures in the Arctic have demonstrated that, over roughly the past 50 years, there has been a warming of about 2 to 3°C as of 2009. The average temperature in the arctic has increased almost twice as fast than the rest of the world. In 2020, the projected increase is up to 4°C as well as 8°C by 2050. A numbers of studies have shown that, based on previous climate records, there has been issues of rising sea levels, alterations in sea-ice dynamics, and permafrost degradation. Though there have been multiple strategies posed and adopted, the government of Canada needs to develop an arctic strategy that is more proactive and systemic than previous actions. This strategy needs to be global in its goals for mitigation while still monitoring social, cultural, and economic aspects
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.
Global warming is one of the most serious problems that people all over the world are dealing with. In fact, however, many people may not realize that global warming also affects animals as badly as it does to human. All Americans should help protect animals from global warming because global warming changes animals’ habitats, decreases food supplies of animals, and even shortens animals’ lifespan.
Thousands of species have become extinct over the last four decades as a result of changes in land use and as a result of global warming. Whether or not the millions of species can adapt and evolve to climate changes is debatable. As this brief overview will report, the human species is not adapting well to the changes. It must be remembered that increases in the levels of carbon dioxide are certainly responsible for the risk many species face, but so is the way land is used, e.g., rain forest destruction. There is a feedback loop wherein plant life and the climate are interdependent. Each affects the other. When forests are cut down, temperatures in that area will rise. Rising temperatures cause other plant life requiring cooler temperatures To die off.
Any species which fall into the categories vulnerable, endangered, or critically endangered are considered to be at risk of extinction. Robert Redford said “I think the environment should be put in the category of our national security defense of our resource’s because it’s just as important as defense abroad otherwise what is there to defend?” People should all take the environment more seriously and protect the future for those to come. It’s our responsibility to ensure that the children to come may enjoy all of earth’s beauty, and not through old issues of National Geographic’s.
In talking about global warming, we need to learn what causes the greenhouse effect. Rays from the sun are taken up and absorbed by water vapor that is natural in the atmosphere. The United States emits the largest man made greenhouse gases in the world. As Americans we must realize the responsibility to reduce the emissions. (Gore, Albert) Water Vapor is eighty percent of greenhouse warming. The last twenty percent results from other gases that are in very little amounts. A huge absorber of the sun’s heat rays is carbon dioxide. Us as humans release a lot of carbon dioxide. When fossil fuels are burned, they release big amounts of carbon dioxide. Carbon dioxide is on the increase in our atmosphere due to car emissions. Approximately eighty percent of CO2 increases because of man’s use of fossil fuels. When there is more carbon dioxide in our atmosphere the more sun rays are absorbed. In result to this happening this will cause the earth and the earths atmosphere to warm. When the earth is warming, water temperatures will start to get warmer. Oceans and lakes will get warmer in result f...
Overall climate change is going to continue, we might not be able to stop it but we sure can slow it down and if we can slow it down we will be able to keep many amenities that we need and keep most of our ecosystems safe. Animals are a huge part in human society and once we realize we are damaging their environment and by damaging their environment we are risking losing the essentials we need to survive. Humans need to reduce the use of carbon emissions and by doing that will greatly increase the chances of slowing down rapid climate fluctuations.
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
There are many different views on whether global warming is actually real or not and possible catastrophic damage it causes. It is a big issue in politics now, everyone is arguing whether or not it is actually real or that it is just a weather pattern. People need to wake up and realize that it is real, just look at the shorter winters and the warmer weather. The Glaciers are melting, crazy weather patterns are happening, so what else could it be? We have more things to worry about as a government though.
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.
There is possibility of decrease in the rate of global warming which will affect us all in a positive way. The endangered animals will be no longer in danger because of the loss in their habitats and also the climate change will be sustainable which mean there will be four seasons in most parts of the
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...
