Global warming, as many of us are probably aware, is the process of the earth continually heating, and there is great debate about what will result from this process. The concept of global warming was first hypothesized by a Swedish scientist named Svante Arrhenius in the 1890s and has caused great debate in recent years (Weart 42). The major debate regarding the issue of global warming essentially revolves around whether the end results will be “good” or “bad” for the Earth. The media often portrays the effects of global warming as being eventually catastrophic for the future of humanity and the Earth. Even though this belief is correct to a point, it can also be said that there will actually be some good results from global warming. The effects …show more content…
of global warming will not be completely bad for the Earth and our society because the constant rise in global temperatures will lead to continuously longer growing seasons (which will lead to an increase in the world-wide food supply), an increase in the number of “warm” days for people to enjoy, as well as an increase in worldwide economic activity. Thomas Gale Moore, a major researcher on economic activity, wrote an article on the perspective of how global warming can be good for humanity in the future.
In his article “Global Warming: the Good, the Bad, the Ugly and the Efficient”, Moore acknowledges this idea that global warming can produce positive results such as longer growing seasons and an increased food supply. He also outlines a discussion about how these positive aspects of global warming will occur. According to Moore, when we look at the rising temperatures on Earth, we shouldn’t panic because this is not an immediate danger to the survival of humans. Even though this rising temperature will change living conditions, we currently don’t live in the best possible climate. The average temperature around the world is predicted to rise two to three degrees Celsius in the next century, so based on this rate of temperature change, it would take hundreds of years before the fate of humans living on Earth would be at serious …show more content…
risk. Warmer temperatures will produce longer summers as well as longer growing seasons as a result. Since warmer global temperatures could lead to more droughts, many people believe that increases in droughts would be a bad thing for the world. When saying that the amount and intensity of droughts are going to increase, this by itself does sound like a very bad thing. However, these people do not look at the other events that will happen simultaneously when the number of droughts increase. Based on these other factors, we collectively shouldn’t have to worry about this. This is because as time goes on, technology will improve. Since the technology to combat droughts will improve over time, humans will be better able to deal with droughts and the effects that will result from the increased number of droughts. One of the major effects of more droughts is that these warmer temperatures will lengthen the summer season and shorten the winter season (Ren 421). Longer summer seasons will allow more time for carbon dioxide to flourish in the atmosphere. So, when more carbon dioxide is released into the atmosphere, this means that more plants will grow as a result of longer time intervals that will allow the growth to occur. Even though carbon dioxide isn’t the only factor in plant growth, this gas is able to speed up the growing process of plants. Also, when more carbon dioxide is released, the gas will react with other greenhouse gases such as methane and will counteract the effects that these other greenhouse gases have on the atmosphere. These increased temperatures will ultimately lead to more time that can be devoted towards growing crops. Increasing the amount of crops that can be grown around the world will lead to an increase in the food supply (Sudetic 80). The increase in the food supply will also lead to a decrease in the prices of food (Ren 424). Decreasing the prices of food will essentially improve the quality of life since more money will be available to use for other purposes such as housing or health care. Research has been conducted that demonstrates this belief of continuously increasing temperatures around the world. This research looks at how many days throughout one year that a city experiences certain temperatures using this year’s temperature data and then tries to predict how many days a particular city will experience the same temperature in 2050 and in 2100. For example, Pittsburgh, Pennsylvania is currently experiencing around eleven days throughout the year where the temperature is above ninety degrees. By 2050, the number of days above ninety degrees in Pittsburgh, Pennsylvania for one year is estimated to be thirty one (“87 Cities”). A similar trend can be observed in other major U.S. cities. This trend supports the argument that warmer temperatures are occurring and they will lead to more opportunities to produce food. However, these research results are very hypothetical. Most of the research conducted on this aspect of global warming includes four different scenarios of how much future temperatures will be affected. The four categories that are included in this research are: “low impacts, moderate-to-low impacts, moderate-to-high impacts, and high impacts from global warming emissions” (“87 Cities”). For example, the number of days presented for the city of Pittsburgh in is actually the highest number that is possible given the worst possible scenario. The other number of days above ninety degrees for Pittsburgh that could result from the effects of global warming include twenty four days for the moderate outcome, nineteen days for the moderate-to-low outcome, and fourteen days for the low outcome (“87 Cities”). Compared to Pittsburgh’s current level of eleven days above ninety degrees throughout the year, it is safe to say that the effects of global warming will have to be massive in order for Pittsburgh to experience more of these hot days. If the effects of global warming have the smallest plausible effect, the average number of hot days throughout the year will only increase by three in 2050 which is an almost insignificant change. With all of this evidence of increasing temperatures, it should be noted that as they continue to rise, we will also be able to better handle catastrophes such as: droughts, floods, hurricanes. The catastrophes mentioned will be a result with rising global temperatures. However, the effects of these catastrophes will be less noticeable. This is due to the rapid advances of technology that we are currently experiencing. Technology has advanced greatly since the 1800’s and it’s safe to say that technology will continue to advance at a similar pace. Also, as wealthy countries become wealthier, they will be better able to repair their home country after these natural disasters take place. So, even if something bad such as a decrease in food supply were to happen as a result of global warming, we would be better able to cope with these negative effects in the recovery phase after these natural disasters have occurred (Moore). People who view that global warming is catastrophic believe that the natural disasters will become worse in nature, but they argue that our ways of dealing with these natural disasters will not improve. Even though it is not certain as to whether or not our current technology will improve, it should be noted that the capabilities of man have increased greatly in the last fifty years and that this trend will most likely continue in the near future. If this trend does exist, it can be assumed that there will be even more breakthroughs in handling these catastrophes with better strategies and better equipment. In having the ability to better cope with natural disasters, this means that the world will remain in a more stable condition (Ren 424). When the Earth is in a homeostatic condition, this means that the world will also be more economically stable. This can be proven by looking at the previous two main ideas. First, longer growing seasons are attributed to longer summers and shorter winters. The shorter winters will mean “less ice and snow… [which] would lead to fewer interruptions to transportation” (Moore S41). Ice and snow are known for slowing down transportation activity within a country, especially during very harsh winters. In terms of transportation, the more ice and snow that are on public roads, a longer amount of time will be needed to transport goods and services. The less ice and snow present on roads will mean fewer delays in transportation and fewer delays in economic trade. Since the winters will be shortened due to increased temperatures, this means that there will be fewer pauses in economic activity throughout the world. These decreases in weather-related interruptions will lead to economic growth as well as a more stable system for trading throughout the world (Moore S43). Economic stability and economic growth are directly related to each other and these two conditions cannot exist independently of each other. The second point of evidence that supports increased economic activity throughout the world relates to the increased supply of food that will result from increased durations in growing seasons. It was demonstrated that a decrease in the price of food would allow consumers to spend more of their money on other factors of life such as housing and health care. Consumers would be able to buy the same amount of food at cheaper prices and they will be able to devote more of their financial resources to other important things such as housing and healthcare. This essentially means that we as individuals will become wealthier in terms of our quality of life. Based on this information, it can be deduced that we as individuals will become more stable in both financial and economic terms as well as in terms of our health. Since these three factors are effectively improving, the effects of global warming don’t seem to be as catastrophic as some people may perceive them. In conclusion, when the term “global warming” is used in the media today, most people will associate “global warming” with the catastrophic and negative consequences that the media often emphasizes in the news.
Even though this view is correct in saying that there will be some negative effects of global warming (such as increased opportunities for natural disasters), this view lacks the idea that other variables will be affected at the same time (these other variables include increases in technology and increases in understanding of how to keep the world more stable). When these other factors are considered, we can see that global warming will actually produce positive effects for humanity and the Earth and all though global warming has some questionable side effects, there will be some positive aspects that will result in the end. These aspects of global warming will create conditions that will lead to longer growing seasons, an increase in the number of “warm” days for people to enjoy, as well as an increase in worldwide economic
activity.
Global warming is a scientific, political, and controversial topic. Some believe it is catastrophic, a slow moving killer hiding in the shadows. Others do not even think twice about it as they race by in a Hummer. Global warming is the gradual increase of temperature throughout different climates. It is caused by the greenhouse gas effect in which greenhouse gases, like methane and carbon dioxide, reflect sunlight back and forth. This reflected ultraviolet light bounces between the earth and the ozone layer and becomes trapped, resulting in a gradual rise of temperature. Over time, the slow rise of temperature causes new climates throughout the globe. The article “What Megablazes Tell Us About the Fiery Future of Climate Change” by Tim Dickinson
The Earth's climate has changed significantly throughout history. In the last 700,000 years there have been seven cycles of glacial advance and retreat. With the abrupt end of the last ice age approximately 7,000 years ago the beginning of the modern climate era was born. In the last century the global sea level has risen 17cm. All three major global surface temperature reconstructions show that Earth has warmed since 1880. Most of this warming has occurred since the 1970s, with the 20 warmest years, having occurred since 1981 and with all 10 of the warmest years occurring in the past 12 years. There is no denying global warming. Once considered a conspiracy theory by the world’s leading governments, industries and populations; global warming
It’s been said by many and thought by others, countless times before. “It’s not that bad. The media and these environmentally obsessive individuals are over exaggerating the negative global climate change impacts”. After all the planets warming has potential to produce positive outcomes as well. It has even been argued that carbon dioxide is not a pollutant; rather it is an essential component for photosynthesis, a process that indirectly supports human life deeming the greenhouse effect as normal. Furthermore the warming of the planet would result in less harsh and cold winters; in turn this would mean fewer deaths, predominantly among vulnerable groups such as the elderly. Environmentally this could potentially produce greener rainforests and enhanced plant growth in the Amazon, increased vegetation in northern
How would you like to live in a home that is beginning to fall apart, but only to go on about your day and continue to neglect it until it all comes crashing down? Humans and animals share this beautiful planet that we call home. But this beautiful home of ours is being regularly and increasingly torn apart by our own ignorant actions. These actions of ours have begun to unravel the very world in which we live, causing a self-inflicted crisis known as Global Climate Change. Global Climate Change is a severe dilemma, and it is continuously becoming more evident to the world’s population that climate change is being caused by changes in the reflectivity of earth’s atmosphere and surface, the ever changing variations of energy from the sun reaching the earth, and the daunting increase in greenhouse gasses.
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....
Climate change is a long-term change in regional or global climate patterns. From the mid twentieth century to now, it has mostly been about a significant increase in average global temperatures. Climate change is a major issue in the world today, and a lot of people feel very differently about the cause of it. The common argument about it is whether climate change is a natural occurrence or if the recent increase in temperatures is because of humans. Climate change is a natural cycle in the Earth’s weather. Before humans started burning fossil fuels, there were still weather cycles on Earth that were as hot or hotter than what it is now. In fact, Earth’s weather now, is on pace with the previous weather patterns in history. Human emitted

But anyways, “Alien” is an acknowledged classic science-fiction movie, and a must-watch for all fans of space and thrill.
Global warming and the greenhouse effect are issues discussed by scientists all the time. A natural process that keeps earths temperature at a livable rate is called the greenhouse effect. The energy from the sun warms up the earth when the rays from the sun are absorbed by greenhouse gasses. The gasses then become trapped in the atmosphere. Carbon dioxide, water vapor, methane and nitrous oxide are the most common greenhouse gasses. Greenhouse gases cause the radiant heat of the sun to be trapped in the Earths lower atmosphere which causes global warming. If there weren’t any greenhouse gasses, the earth would be really cold due to very little sun rays being absorbed on the earth. Global warming can and will lead to several problems that affect the environment in which we humans live in. These problems can lead to warmer temperatures all around the world, it can endanger animals and the wildlife, and it can lead to widespread flooding from the glaciers melting. Here are a few more future effects that I will discuss in more detail about. Damage to human health, Severe stress on forests, wetlands, and other natural habitats, how fish will be affected. Global warming is a serious problem that will affect our generation when we are older.
Climate change is one of the most discussed topics of the twenty-first century. Although this subject is very often on the daily basis of lots of people, most of them do not know much about it. So let us define climate change. People think that climate change is the same thing as global warming. However, global warming only represents one aspect of climate that is temperature. Climate change is any significant change in temperature, precipitation, or a wind pattern that occur over several decades or longer.
The Earth is currently locked in perpetuating spiral of climate change. While the global climate has unarguably been changing since the dawn of it's manifestation, the once steadied ebb and flow of climate change has become increasingly more unpredictable.The risk of rising sea levels, and drought plaguing the fresh water supply, during the time that flooding and sporadic storm conditions turn once fully inhabited regions into uninhabitable death traps. Climate change catalyzed by human's increased production of carbon dioxide, is more noticeable than ever in our recorded history (United States, 2014 National Climate Assessment). Thankfully however, with the changing weather conditions due to carbon related emissions, the change in public opinion about their personalized influence on climate change is also increasing. Kevin Liptak Jethro Mullen, and Tom Cohen note that In reaction to the most recent governmental report on climate change, even the U.S. government believes that a stronger approach needs to be taken to correct our self-generated cataclysm.
In the modern era, climate change is a variation of weather over a long period of time, and it is the most important and controversial global issue. It is arguable in different positions, especially on science, culture, and politics. These three fields all cause a lot of latent concerns. The science of climate change brings out several harmful phenomenon, such as global warming. With respect to the climate change, the culture of humanity may be changed because the changing climate is the most important key factor of forming today’s human societies. Instead, climate change is now a political issue, which will affect the public attitudes directly. In other words, it means the government tends to review and provide latest information in order to adapt and retard the climate change. Over a long period of time, climate change has been taking place because of human activities that affect the scientific, cultural, and political sides.
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.
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
