Early Predictions of Climate Change
From the time of the ancient Greeks through the 19th century to present day, the effects that humans have on the earth’s climate have been studied. Scientists have been able to track the earth’s climate change through out history. In the 1930s a noticeable warming trend was noticed compared to the average temperature in the 19th century. Guy Stewart Callendar, an English engineer, studied the changes in the climate and concluded that the human emissions of carbon dioxide gas could lead to the “greenhouse effect”. “With a new awareness that climate could change in serious ways, in the early 1970s some scientists predicted a continued gradual cooling, perhaps a phase of a long natural cycle or perhaps caused by human pollution of the atmosphere with smog and dust” (Weart, 2003-2010). The concept of the “greenhouse effect” was first introduced in 1896 by Swedish scientist Svante Arrhenius. Together with Thomas Chamberlin, Arrhenius “calculated that human activities could warm the earth by adding carbon dioxide to the atmosphere” (Enzler, 2004, para 1). While a supply of natural greenhouse gases are needed to maintain a sustainable climate, in which humans can survive, too much was predicted to cause a blanket that traps the heat in the earth’s atmosphere. The trapped heat was believed to result in a rise in temperature. According to Environmental Defense Fund, “Even if the temperature change is at the small end of the predictions, the alterations to the climate are expected to be serious: more intense storms, more pronounced droughts, coastal areas more severely eroded by rising seas” (How much is too much, para. 3). Predictions of the effects that humans have on climate have continued over the years. In 1957 oceanographer Roger Revelle predicted that the atmosphere would experience changes as the result of carbon dioxide build…...

...Climate Change SCI/362 February 1, 2012 Chara Webster Climate Change Both here in the states and abroad, communities are already feeling the effects of climate change. Evidence of this change may be seen in increased water pollution, more severe droughts, and larger and more frequent flooding. Because we have so poorly managed land and water in the past, mankind is inadequately prepared to handle the tasks that the ongoing climate change is presenting. Not only are there a number of opinions on this very hot topic, but there are also government-imposed regulations on the matter. Some will argue that global warming is good for us, while others fear that the injection of greenhouse gases will trigger a new ice age. Still, there are others who maintain that self-regulating planetary mechanisms exist which may uphold climate stability even in the face of anthropogenic emissions of greenhouse gases. While I’ll take a closer look at each of these theories, I’ll also consider the stance of the EPA and the UN, and some of the measures that the government is taking in an effort to monitor the impacts that climate change has on human health. About 25,000 years ago, during the last ice age, half of North America was completely covered by ice. A significantly cooler environment would be devastating for humans, as well as plants and animals. “For this reason, Soviet climatologist Mikhail Budyko and others like him argue that we should welcome global warming, and even......

...Climate Change – Anthropogenic or Natural? One of the biggest issues in today’s media is the argument of climate change and global warming, and whether or not it is the result of human influence on the Earth or if it is a natural occurrence. Many people will tell you that climate change is the result of human impact on the Earth, while other people will say that the change is just a natural cycle the Earth goes through. Though both sides can produce evidence as to why they are right or why the other person is wrong, only you can decide what to believe is right and what is wrong. What exactly is climate change? Climate change is the fluctuation in weather and temperature on Earth either in a specific part of the world, or even the entire world itself. Many people question if the climate is even changing, or if it just some conspiracy though up by the government in order to get money. There is no doubt that the Earth’s climate is indeed changing. The Earth is in warming stage that is being called global warming. Although many experts agree that the Earth is in fact warming, they argue over the cause of the warming. Some say that the reason for the warming is because of a natural cycle that the Earth goes through regularly, while others say that man is the cause of the warming. According to some experts the Earth’s temperature has been steadily increasing since the 1800’s. For this reason they are saying that the past two decades have been the hottest on record......

...Unwinding complex systems, fostering innovation and controlling climate change Stepping towards global prosperity in a greener environment Shitij Nigam mail.snigam@gmail.com Introduction The question of climate change - and whether to tackle it or not - has always probed the minds of policy makers. Indeed, the issue of how it may be technologically tackled is solved to a certain extent. But whether such solutions may be implemented in a sustainable manner, and which hold grounds with the interests of all stakeholders – demands a higher level of scrutiny, especially into the consequences of taking overtly aggressive actions. Indeed, Environmentalists have been continuously plagued by Economists regarding the viability of any steps which might be taken in this arena, especially in policy-making, given the substantial amount of initial investment involved in ‘green’ projects, supplemented by the fact that the rates of returns remain inevitably slow, if not supplemented by uncertainty in most cases. The term “Emerging Markets” has been loosely thrown around the table for the past few years, being crudely defined as ‘nations with social or business activity in the process of rapid growth and industrialization’[1]. China and India instantly come to mind as perfect examples of such ‘markets’, given their perception as future cash-cows, owing to the vast scope of industrial expansion, especially within themselves – owing to the aggregated strength of their respective......

...Every place, country, city, region has its own climate. Climate plays one of the important roles in people’s life. Climate is defined as the average weather, which means variety of weather conditions as rain, snow, hail, sun, and wind over period of time about 30 years that can be measured in any particular place.( IPCC Third Assessment Report - Climate Change 2001; editor:A.P.Baede) Climate change is a variation of average weather. There are 2 causes of climate change. The first is human activity which includes deforestation, burning fossil fuels, agriculture, transportation and infrastructure. The second is natural causes which include volcanic eruptions and variations in solar outputs. These causes have negative effect on the natural environment which leads to increasing of temperature, increasing in sea level, changing of precipitations, extremely weather, killing species of animals, birds, fish and plants. This essay will show that the causes of climate change have different effects on the environment. Atmospheric carbon dioxide variations, volcanic eruptions and solar outputs, have negative impacts on animals, plants, and environment. Climate is always changeable. One winter can be early, another late; one summer wet, another dry (Carter 2000,34). For the last century climate has dramatically changed. Consequences of climate change may manifest itself as rapid and through the long period of time. Climate change could lead to number of catastrophic disasters as......

...A Meta-Analysis of the Economic Impacts of Climate Change Policy in the United States Adam Rose* and Noah Dormady** This paper provides a meta-analysis of a broad set of recent studies of the economic impacts of climate change mitigation policies. It evaluates the infiuences of the impacts of causal factors, key economic assumptions and macroeconomic linkages on the outcome of these studies. A quantité regression analysis is also performed on the meta sample, to evaluate the robustness of those key factors throughout the full range of macro findings. Results of these analyses suggest that study results are strongly driven by data inputs, economic assumptions and modeling approaches. However, they are sometimes affected in counterintuitive ways. 1. INTRODUCTION The macroeconomic impacts of climate change mitigation policies are controversial among both scholars and the policy-making community. Results range from predictions of severe economic harm to significant overall economic gains. Given the unresolved nature of this debate, this paper seeks to shed light on it by evaluating a wide range of macroeconomic studies through a metaanalytic approach. Meta-analysis is a method for evaluating a cross-section of studies on a given topic, and evaluating the impacts of assumptions, input variables and modeling approaches on the overall findings of the studies. In essence, meta-analysis is a study of studies (Borenstein et al., 2009; Lipsey and Wilson 2001). The......

...Climate Change: Is Global Warming To Blame? Climate change is a serious reason for concern, because it affects every person living on the planet. The vast majority of the scientific community claims that anthropogenic global warming is to blame for these changes. However, there are a small number of people who deny the very existence of global warming. Their words carry a certain amount of weight in some circles, but they lack scientific proof to support these arguments. The effects of climate change are undeniable. Research conducted by the Intergovernmental Panel on Climate Change (IPCC) and other reputed meteorological institutions proves that average yearly temperature has been steadily growing over the last decades. The sea levels have also been rising, and the number of floods in different parts of the world has increased dramatically. Glaciers in the Northern Hemisphere have started to melt. This caused more icebergs to drift into the ocean. They currently pose a serious threat to both, cruise and cargo ships that course through the waters of the northern regions. There are reports of some icebergs being spotted far to the South from Greenland. Over 95% of scientists agree that these changes are caused by the “greenhouse effect”. There is some solid evidence which proves that people are directly responsible for the global warming that is fueling this climate change. Destruction of forests, burning of fossil fuels and environmental pollution are the main......

...Climate Change and How the Media Portrays It The average educated person would define climate change as the average weather changing or global warming. It is patterns of temperature, precipitation, humidity, wind and seasons. Climate is what makes up all natural ecosystems and is what helps sustain these ecosystems. The climate change today is changing the world. It’s affecting the natural ecosystems negatively. This is because climate is tied to almost everything. The change in climate will change the way people, animals, and plants have to survive. For example, a change in the usual timing of rains or temperatures can affect when plants bloom, when certain bugs hatch, or when streams are at their highest level. This can affect pollination of crops, food for migrating birds, spawning of fish, water supplies for drinking, forest health, and much more. Many people mistake global warming and climate change to be the same thing. Although they are very similar, global warming is what causes climate change. Global warming is the rising of global temperature and ocean temperature. This is what causes the climate change events listed above. Global warming is a global event while climate change is a more regional change in the atmosphere. There are many people who think climate change is not happening. The National Academy of Science has studied climate change and confirmed that it is real and humans are causing it. According to the Climate Impacts Group at the......

...Joellen Hiltbrand English 221-0850 September 11, 2015 Essay one: Climate Change Climate change is a sensitive topic here in the United States. People are very stubborn when it comes to their own ideas and beliefs on a topic. Some people believe climate change doesn’t exist, some believe it isn’t that bad, and others blame clime change on the government. Even though people have their own ideas on climate issues, change is happening and we need to do something about it to help ourselves, and our future generations. Climate change has risen from the greenhouse effect, and it is a worldwide problem. There are many ways to help with the climate change, and there are things everyone can do to help. There needs to be major changes implemented in terms of dealing with the climate change. We need a proactive leader to get the public educated on climate change, we need adaptive and preventative measures set up for climate change, all major parties in our government to work together to come to a conclusion on climate change policies, and we need to reform the United Nations to help the world deal with the climate change. The first step in dealing with the climate change is having a proactive leader who will use strategic leadership skills to enlist change among the nation, and the world. We need a person who can help encourage the people to change. Mike Zajko states in the article, The Shifting Politics of Climate Science, “the public stands to benefit from a more accurate......

...1. Introduction Over the last century, climate change has become one of the greatest threats facing the world. There is overwhelming scientific consensus that the increasing global temperature and the variable weather condition are closely related to the increase of greenhouse gases. In order to tackle the issue of climate change effectively, the Kyoto Protocol has been established. However, the rate of climate change is beyond prediction and the adverse impacts of climate change are increasingly serious. Besides, the debate about the main cause of climate change is significant. As the main driver of climate change is difficult to identify, countries face the challenge to formulate practical strategies to reduce greenhouse gases. This report will define climate change and explore what is the main driver of climate change as well as focus on climate change response strategies in Kenya. 2. Definition of Climate Change Climate change is characterized as observed increase in global average temperature of the earth. Climate is totally different from weather. Weather is the state of atmosphere at a place and time as regards heat, cloudiness, wind and rain (CCIR-NYC 2005, p. 1). However, climate is a region’s weather patterns in a relatively long period (CCIR-NYC 2005, p. 1). The CCIR-NYC (2005, p. 1) claims that the variations of the state of climate on space and time are the dominant features of climate change. It is reported that global average temperature has...

...climate change global warming Heading There has been much discussion recently about global warming do you know what are the causes behind the global warming? The phrase Global Warming has specific meaning. "Global" means something above borders or international. "Warming" means an alarm that something bad will happen. The whole phrase means increase in the average temperature of the earth's atmosphere that causes changes in climate around the whole world, which refers to the meaning of global. For years, global warming was a scientific theory nobody cared about except scientists. Since the 1970s, the scientists discovered the fact that the temperature of the earth is increasing, and that the environment will encounter a real problem because of the humans activities on the earth. Even in the late 2000s, both of the government sector and the private sector were still ignoring the issue, due to considering their own benefits. These worries sat the governments and the scientists to it take in consideration more than ever. Both of them started collaborating to conduct the problem. Thus, recently all of the classifications in the world's community neither they were scientists, politicians, students nor children became more and more interested and aware of the global warming issue, and the clue is that most people became more informed of what the global warming really means. Also, the media paid great attention to it by showing programs about it and interviewing experts......

...TOPIC: CLIMATE CHANGE The topic of climate change is like a puzzle with many different pieces—oceans, the atmosphere, ecosystems, polar ice, natural and human influences. Scientists have been working on this puzzle for more than a century, and while there are still gaps in our knowledge, most experts feel we have the puzzle is complete enough to show that human activities are having an adverse effect on our planet. This talks looks at many of those puzzle pieces, the evidence behind them, and the conclusions we can draw from them. OUTLINE • What changes climate? • Is it real? • How do we know? • Why should we care? • How sure are scientists? • What next—what can we do? What changes climate? Changes in: – Sun’s output – Earth’s orbit – Drifting continents – Volcanic eruptions – Greenhouse gases Scientists have a good understanding of what has changed earth’s climate in the past: • Incoming solar radiation is the main climate driver. Its energy output increased about 0.1% from 1750 to 1950, increasing temperatures by 0.2°F (0.1°C) in the first part of the 20th century. But since 1979, when we began taking measurements from space, the data show no long-term change in total solar energy, even though Earth has been warming. • Repetitive cycles in Earth’s orbit that occur over tens of thousands of years can influence the angle and......
