Global Warming : A Critical Analysis

“Scientists’ overwhelming conclusion is that climate change is happening and human activity is the primary culprit,” (“Climate Change”). The world we live in is falling apart more and more every day. Pollution; Global Warming; Climate Change; These are all problems that caused by people who have come forward in recent years, one of the biggest issues is climate change. The United States government needs to take aggressive steps to combat climate change because scientist have warned that if the climate changing progresses at its current rate, it could have disastrous consequences for life on Earth. Data shows that climate change is linked to rising sea levels, droughts, an increase in the risk of extinction of many species, and the increase in severe storms. With all the issues that are connected to climate change we are not doing enough to try to counteract the lasting effects it has on our environment.

The Global Warming theory has become increasingly popular over the past few years. Citizens of the world are being encouraged to be more environmentally conscious by others including politicians, celebrities, and world organizations. The problem with the theory lies in the fact that it has become more and more controversial as it gains publicity and attention. The basic concept behind this theory is that the earth was made with a balance of “greenhouse gasses”. These gasses are naturally occurring within the atmosphere and they essentially make the planet habitable by keeping it warm.

Climate change has been a subject of discussion in the media for many years, supported with the use of arguments against oil polluting the environment and extreme scare tactics of Polar ice caps flooding civilians backyards. The issue has been ignored by the majority of lay people as seeming too complicated, and with all the conflicting information in the media in the past, who can blame them? However, scientifically, climate change and what perpetrates it is fairly simple to understand and society as a whole is beginning to come to a clear consensus on climate change. Thanks in part to more readily available forms of media and information, people have become cognizant of the fact that climate change is a legitimate problem which requires immediate amelioration. While this may seem melodramatic, society is realizing that climate change is an issue which can no longer be denied if the human race wishes to continue.

Global warming is the steady heating of Earth’s land, oceans, and atmosphere caused primarily by human activity. Climate change is one of the world’s biggest challenges right now, from people actively arguing that it doesn’t exist- to other’s who don’t care enough to do anything about it. There’s evidence showing that climate change is happening and affecting our world now and from what it seems, if action isn’t taken, major consequences will soon arise. Most of the world’s land mass has experienced a 0.2-1.0 degree Celsius average temperature increase since the 1970s, the temperatures of the Artic has increased at almost twice the mean global rate. Climate change is caused by human factors such as greenhouse gases and ozone depletion and because humans are so dependent on fossil fuels in their day to day lives, the issue at hand is only going to get worse.

The debate about whether human activity or natural occurrences impacting climate changes has been plaguing scientists, politicians, and journalists across the globe for quite some time. People’s lifestyle must change if a positive effect is to be caused on the climate and recreate a safe environment. Changes such the reduction of burning less fossil fuels which reduces greenhouse gases, changes in public perception are needed to clean the environment.

Nowadays, the whole world are paying attention on the controversy about climate change and global warming. Hot topics include whether global warming is occurring, warming level in modern times, causes, effects and what that action should be taken (Science Daily). On one hand, there is a strong consensus that human and industries take main responsibility for the rapid increase of global surface temperatures in recent decades, and greenhouse gases such as carbon dioxide is the major cause of global warming. Meanwhile, some people that come from organizations with

The idea of climate change, for many, is an opinionated subject with much discussion of whether it is a real issue or just a natural phenomenon. However in recent years it is clear to see that trends in the Earth’s climate and surface temperature has spiked to levels never seen before. Despite all the evidence of the high levels of greenhouses gases and the rise in temperature, many still believe that

• Carbon dioxide (CO2) is a greenhouse gas that warms the atmosphere. • Since pre-industrial times, atmospheric CO2 concentrations have increased from about 280 parts per million (ppm) to over 380 ppm. Current concentrations of CO2 and other greenhouse gases are unprecedented in at least the last 650,000 years, based on records from gas bubbles trapped in polar ice. • Independent measurements demonstrate that the increased CO2 in the atmosphere comes

Thesis Statement: Global warming is a growing concern of scientists and researchers who believe that it is a serious problem for our planet. The concerns and research have also been questioned and have even been called myths. Millions of people find themselves affected by these weather pattern changes and are concerned for their futures. Activists on both sides of the argument are very passionate and not afraid to attack each other in every way they can. There are many questions that are still not answered, however, we continue to see drastic weather changes to Earth. We must go beyond the arguments and learn as much as we can to stop what could possibly lead to the destruction of our planet, our way of life and our future.

The earth is a beautiful and extraordinary planet, but are we treating it right? For the past 20 decades, temperatures have been rising along with hundreds of factors contributing to it. Climate change concerns the public as they wonder if its occurring, how much has occurred in the modern era, what has caused it, what the effects will be if we don’t do anything about it and much more. Many people and scientist agree that mankind is the number one cause of climate change. Humans have influenced this by greenhouse gases, methane nitrous oxide.

In recent years, the controversial subject of global warming has been more predominantly brought to our attention. Is the threat of global warming real? Is it man-made or is this just a natural cycle of earth? Does it really affect earth’s inhabitants? Should action be taken against it? If so, what kind and to what extent? It cannot be only a coincidence that the alarmingly rapid climate change coincides perfectly with the increased amount of pollutants that humans release into the environment. The once stable climate has in recent years begun to skyrocket, thus altering the delicate structure of earthly life. This proves to be hazardous to the future of the planet; some people worry that many of the resources the environment provides that

Carbon dioxide is the greenhouse gas naturally found in the atmosphere. Since the advent of the Industrial Revolution in the 1700s, humans have devised many inventions that burn fossil fuels such as coal, oil, and natural gases, which, along with other human activities such as clearing land for agriculture or urban settlements, help some of these greenhouse gases accumulate in the atmosphere that in turn trap more heat radiation in the atmosphere causing the Earth’s climate to become warmer than it would naturally (Mastrandrea). This unnatural phenomenon is termed global warming by scientists and they blame it for an increase in the Earth’s surface temperature of about 0.6°C (about 1°F) over the last 100 years (Mastrandrea).

Why are greenhouse gas concentrations increasing? Scientists generally believe that the combustion of fossil fuels and other human activities are the primary reason for the increased concentration of carbon dioxide. Plant respiration and the decomposition of organic matter release more than 10 times the CO2 released by human activities; but these releases have generally been in balance during the centuries leading up to the industrial revolution with carbon dioxide absorbed by terrestrial vegetation and the oceans.

Climate change otherwise known as global warming has been an ongoing issue for decades. Beginning in the 19th century, climate change has increasingly affected Earth and its atmosphere. Rising levels of carbon dioxide are warming the Earth’s atmosphere, causing rising sea-levels, melting snow and ice, extreme fires and droughts, and intense rainfall and floods. Climate change has and will continue to affect food production, availability of water, and can add to many health risks in humans and animals. In fact, in an article by Justin Gillis titled, “Scientists Warn of Perilous Climate Shift Within Decades, Not Centuries” he focuses on a paper written by a former NASA climate scientist, James E. Hansen, explaining the effects of climate change on Earth today. Although many believe Hansen’s theories in the paper are quite far-fetched, the author mentions, “Despite any reservations they might have about the new paper, virtually all climate scientists agree with Dr. Hansen’s group that society is not moving fast enough to reduce emissions of greenhouse gases, posing grave risks” (Gillis). Gillis validates the fact that climate change has been rapidly expanding throughout Earth and society has not been able to reduce it fast enough. Many negative risks are being posed and will continue to mount if the issue of climate change is not taken seriously. Although climate change negatively affects nearly all aspects of Earth, it poses a big

When one encounters the concept and idea of global warming, we inquire a wide range of opinions, facts, assumptions, and philosophies. As the general population of the world, the idea
