GLOBAL WARMING
The term global warming was first used in its modern sense in a science paper dated 8th August 1975 in the journal science called “Are we on the brink of a pronounced global warming?” The words used by Broker were new and they represented a convincing recognition that there was an amount of warming in the climate. Scientists previously used the phrase “inadvertent climate modification” because even though it was realized that humans could bring about a change in the environment, no-one was particularly sure as to which direction it was going. The word Global Warming was first used by National Academy of Sciences in 1979 in a paper called The Charney Report, which wrote:

Nitrous oxide being 300 times more powerful than carbon dioxide. Gases such as chlorofluorocarbons have been banned in many parts of the world because of their ability to degrade the ozone layer. Such gases trap the heat thousand times more than CO2 does. But because they have low concentration than CO2, none of them add that much warmth to the atmosphere as much as CO2 does. To understand the impacts of all gases together, scientists usually talk about all greenhouse gases in terms of the commensurate amount of CO2. Yearly emissions of ‘carbon dioxide equivalent’ have gone up by 6 billion metric tons worldwide since 1990, more than 20% increase.

Rising temperatures worsen smog pollution and increase the number of “bad air days” wherein it becomes hard to breathe. Irritated eyes, nose, and lungs are some of its symptoms, and is mainly dangerous for people who suffer from respiratory diseases like asthma. Unhealthy air pollution will keep getting worse as the climate changes. Across the globe, climate change is the reason for making hot summer days hotter and stretching their numbers to never ending heat waves. As the temperature rises, so are the number of illness, emergencies and deaths. In a way, the heat is causing more than just discomfort. Record highs in the summer of 2010 were seen in more than 37 states of the U.S., and in much of the
You may have heard people talking about how the weather is very different today than it was ten years ago. You may have noticed changes in the weather yourself. The earth's climate has changed many times over millions of years. And you may have heard about Global Warming. You may ask what Global Warming is. I remember the first time I ever saw and heard about Global Warming when I was just a little girl. I was watching the TV and a commercial came on, it was a cartoon with two kids and an adult. They were in the park enjoying the day. The adult started talking about Global Warming, the kids didn’t know what he was talking about, so he fast forward the time and showed them what the earth is going to look like when they are
The 19th as well as the 20th century have been the most prolific time periods in modern history as concerns science, technology and socio-economic development. Within these two centuries we witnessed the discovery of electricity, the invention of the engine which played a very important role in the maturity of the well-known industrial revolution. Through this revolution people began to live in a more decent and comfortable manner; new commodities were produced and entire new kinds of industry were developed. Although all these inventions, discoveries and scientific breakthroughs improved in an outstanding way our well-being, they also provided us with some troubles that scientists had never foreseen or even imagined.
The earth as we know it is steadily changing. Weather its evolution, technology, weather or our environment, nothings is what it used to be. Climate is a major factor that is changing. This has been going on for quite some time yet, not taken seriously. Our planet has been much warmer in the past 2 centuries then ever before and scientist are working frantically to reduce this trend,
Global Warming is the term to describe a gradual increase in the average temperature of the Earth’s atmosphere and its oceans, a change that is believed to be permanently the Earth’s climate. Global warming is also the heating of the Earth’s surface. Scientific organizations in the world acknowledge that according to a NASA report 97% of the climate change was due to human activity alone. Global warming has change over the years most scientist don’t believe that it can just be human activity , scientist research suggest that the earth is warmer today than when it was in the 1800s. Although their technical meanings differ (i.e., global warming refers to increases in average global surface-level temperatures; in contrast, climate change encompasses myriad altered climatic patterns resulting from anthropogenic greenhouse gas emissions; Environmental Protection Agency [EPA], 2012), these terms are frequently used interchangeably in public discourse, including in news
These gasses trap warmth and reason the planet to warm through a procedure called the greenhouse effect. Since 1751 around 337 billion metric huge amounts of CO2 have been discharged into the climate from the using of fossil fills and concrete generation, expanding air CO2 from the pre-mechanical level of around 280 ppm (parts per million), to a high of 400 ppm in 2013. Methane, which is expanding in the climate because of farming and fossil fuel use, traps 84 times as much warmth as CO2 for the initial 20 years it is in the environment, and is in charge of around one-fifth of a dangerous atmospheric climate change since 1750. Nitrous oxide, fundamentally discharged through farming practices, traps 300 times as much warmth as CO2. Over the twentieth century, as the convergences of CO2, CH4, and NO2 expanded in the air, the earth warmed by pretty nearly 1.4°.
Global warming is correlated with hot, humid days that can activate asthma symptoms. For patients with chronic lung diseases the onset of an intense heat wave can lead to death. “A study of New York City summers from 1991 to 2004 found that each 1°C above an empirically derived temperature-health effect threshold for the population resulted in a 2.7% to 3.1% increase in same-day hospitalizations for respiratory diseases,” (Bernsetein and Rice pg 3). The elderly with respiratory diseases and people living in urban areas due to amplification of temperature rises are the most prone to the effects of heat waves. (Another result of increase in temperature is the increased likelihood of forest fires releasing particulate matter (PM) and carcinogens, which have also been, linked to increased likelihood of asthma symptoms and hospital visits. PM can carry absorbed toxic compounds deep inside the lung do to their size to weight ratio. The majority of PM in the atmosphere comes from desertification and droughts and these natural events are likely to increase as a result of global warming. Even individuals with healthy functioning lungs were shown to have decreases lung function after exposure to PM and carcinogens. People with Chronic Obstructive Pulmonary Disease are effected most by air pollution because sometimes the pollution can lead to
Global Warming is an increase in the average temperature around the world. Scientists have been able to trace the global climate and concluded that over the last ten thousand years, the climate of the earth has been relatively constant. In the twentieth century, the global temperature increased 0.740°C. The change in the warming, and cooling, of average global temperatures cause climate change, a change related to climate patterns such as temperatures, rainfall, wind and humidity. This flux in temperature is affected by multiple factors making it hard to determine the true source of problem. Evidence supports that the earth's warming is natural; however, some data indicates that the warming trend has increased due to human activity.
Global warming, or climate change, is a widespread issue which many people aim to combat due to the destruction it causes to the environment and how it may threaten humankind's existence if continued unchecked. Some oppose global warming purely because of the harm it does, whereas others have religious reasons, such as Christians believing mankind was placed on earth as a steward, to care for the environment, and should thus oppose global warming as it threatens the environment and thus violates the trust that their God placed in them.
According to the National Aeronautics and Space Administration, the global temperature has risen about two degrees Fahrenheit since the late nineteenth century (“Climate”). Scientists define climate change as the escalation of the earth’s average temperature by natural causes or human inducement. As gases in the earth’s atmosphere increase, earth’s temperature follows coherently. Scientists cite a correlation between the earth’s increasing temperature and gases such as carbon dioxide, nitrous oxide, methane, and chlorofluorocarbons in the atmosphere. Scientists have found that through human activity these gases show an increase. The upsurge of gases has a lasting effect on the environment: “Scientists warn of the loss of ecosystems and
There is no myth concerning climate change, only vested interests arguing over humanities role in our current climate change event. By careful reasoning and logic this paper sets about systematically showing that not only is climate change real but that currently the planet is experiencing a period of warming that is without equal within any of our historical data. Most confronting of all is that humanity is significantly influencing this current event and has the ability to mitigate the consequences.
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.
Hurricane Katrina, hit our shores in 2005. As Al Gore, former Vice President and long time Environmentalist, points out in his book An Inconvenient Truth, “Hurricane Katrina caused approximately $60 billion in insured losses” (Gore 102). A further impact on the world economy would concentrate in the UK who will be heavily affected by the melting of glaciers, whose “annual flood losses alone could increase from 0.1% of GDP today to 0.2-0.4% of GDP once the increase in global average temperatures reaches 3 or 4 degrees Celsius” (Stern viii).
Global warming is the gradual increase in the overall temperature of the Earth’s atmosphere due to Greenhouse gasses. Greenhouse gasses are a product of the Greenhouse effect, a phenomenon in which particular gasses in the atmosphere trap heat and allow only light to escape, much like the mechanism of the glass on a green house. The term was first coined in the 17th century, around the time of the industrial revolution. Scientist began to notice that the earth was getting hotter, and will continue to get hotter as the years pass by, eventually resulting in immense global climate change. Despite evidence of the phenomenon, the topic has been a debate filled with controversy since its existence. There are those who believe that Global warming is a hoax, but unfortunately there is evidence that proves the legitimacy of global warming and it’s affect on climate change.
One of the most all time debated and controversial topics to date in science is global warming. Over the last few decades climate change have lead scientist to develop a theories that human beings are the major contributors to the global warming crisis. Many theories suggest that different types of issues contribute to the warming of the planet but the mitigation strategies to slow this process down vary as well.
other ways. The heat that is produced can damage our crops. The temperature will allow
