One of the biggest problems the world faces today is global warming. It refers to an increase in average global temperature that causes change in climate and affects other resources in the world. Global temperatures have significantly increased over the past few decades. According to the Global temperature statistics by NASA, the average temperature has increased from -0.22 Degree Celsius in 1880 to +0.56 Degree Celsius in 2012 (NASA, n.d.). This essay will examine the main effects of global warming by looking at the threats to wildlife and habitat, rise in sea level, and health impacts on humans.
One main effect of global warming is the threat to wildlife and habitat. The increase in global warming disrupts wildlife species and causes extinction to animals that cannot adapt (NRDC, n.d.). One example is the decrease in polar bear population. As the ice continues to melt, some polar bears are drowning because they have to swim longer distances to reach the ice sheets. The U.S. Geological Survey has predicted that two-thirds of today’s polar bear population will be gone by 2050 due to the melting of the Arctic ice cap (New England Aquarium, 2013; USGS, 2007). Researchers of the U.S. Fish and Wildlife Service said, “Without enough sea ice, the bears’ disappearance probably take place as young cubs failed to survive to adulthood and females were unable to reproduce successfully” (Zabarenko, 2013). Animals that live on ice are not the only ones who affected by global warming. Many species on land are also affected due to climate change. Another specie that is declining in population is moose. The New Hampshire moose population has plummeted by more than 40 percent in the last decade from 7,500 moose to 4,500 today (National Wildlife Federation, 2013). The number of moose is shrinking because global warming is causing shorter winter, which means less parasitic ticks on moose are dying. This causes moose to become so heavily infested with ticks that they eventually become anemic and die (Ross, 2013).
Rise in sea level is another effect of global warming. The melting of glacier ice in Arctic leads to an increase in sea level (Poore, Williams, & Tracey, 2001). According to the U.S. Environment Protection Agency, global sea levels have risen about 8 inches from 1880 – 2009, and the rate of the increase is expected to accelerate in coming years.
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
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.
Sea level rise: As of January 2015, globally the sea levels measured 61.91 mm. Sea level rise is caused primarily by two factors related to global warming: the added water coming from the melting of land ice and the expansion of sea water as it
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.
The negative side of global warming is that it leads to the 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 changes reflect 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 the ice has decreased by 40 % and the region has warmed up to 2 degrees (News global warming).It means, that global warming affects the wildlife and due to the melting of ice flora and fauna dies....
The global sea level rose about 17 centimeters (6.7 inches) in the last century (NASA). The rate in the last decade, however, is nearly double that of the last century. With climate change on the rise, higher temperatures, more droughts, and wilder weather will prevail. These changes will affect animals, ecosystems, and people.
Global Warming is a condition caused by greenhouse gases and human activities. The increased concentration of greenhouse gases due to activities such as deforestation and fossil fuel burning is causing the Earth’s atmosphere and oceans to warm up. As a result of this, global warming has some serious effects in the shape of extreme weather, species extinctions, and rising sea levels. These effects can contribute to the changes that are taking place all over the world, most of which are dangerous enough to pose a threat to the survival of life on Earth in the future.
Many climate scientists, researchers, and environmentalists are expressing concerns about shifts in the overall climate of the earth. It is believed that a dramatically dangerous warming is taking place in the overall global climate, a problem that is referred to as "global warming”. Global warming is the observed century-scale rise in the average temperature of Earth’s climate system. This temperature rise is due to the damaging effects of deforestation and the burning of fossil fuels. It is our responsibility to preserve our planet and our way of living but in order to do that we need to act now. If we continue to destroy the planet with no regard as to how serious this matter is there could be several negative effects to us as human being and other living thing on Earth. This is why global warming is truly a global issue and needs to be tackled collectively. We must to act now in order to reduce the dangerous levels of carbon dioxide emissions and we must to work together.
Our planet has managed to survive and thrive for about 4.54 billion years. In the last 2 million years we have caused enough damage and destruction to make our world “broken” beyond repair. We will not be able to get back the world we once had. The reason behind this is global warming, specifically, the increase of the global temperature due to the burning of fossil fuels and the release of greenhouse gas emissions into our atmosphere. If we do not make the issue of global warming a priority in today`s society, our entire way of life will be at risk. There are many reasons why so many people believe global warming should be a concern. Thoroughly examined points include: scientific predictions, rising temperatures, human causes, drastic climate changes and animal adaptations. Though there are several points arguing how global warming should not be a concern, the reality of the matter is that it needs to be taken into consideration on a global scale before it is too late, as to do nothing would have devastating implications on humankind.
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 heating and cooling has occurred on a cycle for millennia, however in the past thirty years the increased use of energy and fuels by humans has drastically changed this natural occurrence (Juerg, 2007). The largest cause of this warming is the release of carbon dioxide from the burning of fossil fuels. Carbon dioxide levels are twenty-five percent higher than they were in 1957 (UCS, 2013). This seemingly insignificant change has caused a myriad of negative effects. The endangerment of species, rising sea levels, and increased natural disasters are just a few examples of change brought about by global warming (Juerg, 2007).
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
One of the most substantial problems in the world today is global warming. This gradual warming of the earth is in occurrence at an extremely slow rate but it is happening. Many scientists believe that as human’s work and release greenhouse gases into the earth’s atmosphere, it can become dangerous for the long lasting life of humans and our environment. “Unless we take immediate action, the impacts of global warming will continue to intensify, grow ever more costly and damaging, and increasingly affect the entire planet - including you, your community, and your family” (“Global Warming Impacts”). Everyone should be knowledgeable about global warming and the dangers that it brings to our planet. This essay will examine
Birds are a species that will be affected by a change in the climate. Global warming might result in birds finding a more permanent home in northern areas of the Northern Hemisphere. The ecosystems of fish will be affected by global warming in a variety of ways. The chemical composition of water could be changed.
Global warming is a serious problem with two major effects: increasing sea level and degradation of wildlife. Increase in sea level affects 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 on our planet.
