Global Warming
Our planet's atmosphere traps energy just like a greenhouse. Energy from the Sun can enter the Earth’s atmosphere, but not all of it can easily find its way out again.
What blocks the Sun’s energy from escaping from the Earth? Unlike a greenhouse, the Earth does not have a layer of glass over it! Instead, molecules in our atmosphere called greenhouse gasses absorb the heat. Greenhouse gasses include water vapor, methane, ozone, nitrous oxide, and carbon dioxide. There may not be much of some of these gasses in our atmosphere, but they can have a big impact. Each greenhouse gas molecule is made of three or more atoms that are bonded loosely together. These molecules are able to

About 30 gases produced by human activity have been identified as contributing to the greenhouse effect. These are sometimes called greenhouse gases. The main ones are carbon dioxide, methane, CFCs and nitrous oxide. Sunlight reaches the Earth's surface, is reflected off it, and is prevented from escaping from the atmosphere by this layer of gases, which acts like glass in a greenhouse.
Up to a point, the greenhouse effect is a natural process, and naturally occuring carbon dioxide is not dangerous. Without greenhouse gases, the average temperature of the Earth would be -19C , in other words, too cold for us to live. However, the concentration of the greenhouse gases in the atmosphere has changed dramatically: since the 18th century, carbon dioxide has increased by 30%.
There is disagreement among scientists about the seriousness of global warming. Most scientists agree that the global temperature is rising. They do not agree on more specific elements of the issue: How much will it warm up? What will happen if it does warm up? How far are humans responsible? What should we do to stop it?
Scientists believe that if we go on producing gases at the rate we do now, it is likely that the Earth's average temperature will rise by about 0.3 degrees C every ten years. This
NGS integrates greenhouse into other major policy initiatives, such as the Natural Heritage Trust, and launches new measures to increase greenhouse emission reduction activities across the Australian community. It provides the strategic framework for an effective greenhouse response and for meeting current and future international commitments. It will provide a fresh impetus for action by governments, stakeholder groups and the broader community and set directions for that action into the next century.
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.

The climate is changing. The earth is warming up, and there is now overwhelming scientific consensus that it is happening, and human-induced. With global warming on the increase and species and their habitats on the decrease, chances for ecosystems to adapt naturally are diminishing. Many are agreed that climate change may be one of the greatest threats facing the planet. Recent years show increasing temperatures in various regions, and increasing extremities in weather patterns. Research has shown that air pollutants from fossil fuel use make clouds reflect more of the sun’s rays back into space. This leads to an effect known as global dimming whereby less heat and energy reaches the earth. At first, it sounds like
Though gasoline cars make lives of humans easier to travel, it threatens the environment. Climate is defined as weather conditions existing in a particular area over a period of time. When changes in weather patterns start to occur, this is called climate change. Peter Singer describes carbon emissions would extinguish human life. Climate change is a disastrous event because there is a wide range of environmental impacts affecting life expectancy. In different geographical areas, climates will change if temperatures influence them to fluctuate. The major cause of climate change is human expansion of the greenhouse effect. Kolbert presents scientific research about climate change and global warming leading to a global catastrophe. Any process that causes the Earth’s temperature to become imbalanced affects the climate. While climate change is a natural process, purchasing a SUV and doing human activities of all kinds has impacted on the atmosphere by burning fossil fuels for energy.
The climate on the Earth is changing. Currently, the temperature of the earth’s climate system continues to rapidly increase which leads to global warming. Global warming, by definition is the “gradual increase in the overall temperature of the earth’s atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants”(Webster’s). There are many reasons why global warming occurs, such as human activities and the increasing of gases; for instance carbon dioxide in the atmosphere. To reduce the issue, about 200 countries have signed Kyoto Protocol that states that they must lower four greenhouse gases. The Kyoto Protocol is an international agreement linked to the United Nations Convention on climate change and it commits the Parties to reduce greenhouse gas emissions.
Since the Industrial Revolution, factories have been polluting the air and unknowingly contributing to the process known today as global warming. Even to this day, people proceed to do detrimental things to the environment. Global warming is one of the gravest issues the world faces nowadays. With all the other concerns society has to face, it is essential that people act out now and do what is necessary to establish a brighter future. By using appropriate procedures to conserve energy and save natural resources, people can counteract the process of global warming and its disastrous effects.
We should all be very concerned about our future on Earth as human beings. We may not be at such an immediate risk of burning to death, but our future descendants are. Every year, the overall temperature has gone up slowly. Eventually Earth will be too hot to live on, and the human race will become extinct! The best way to save our future is to start now. Americans should be conscientious of global warming and should watch their CO2 emissions because increasing CO2 concentrations means an increase in Earth’s temperature.
Imagine you are placed into the future. The year is 2100. You begin to live in this
Global warming has becamebecome an accepted fact in the present century (Li et al. 2017). the consensus in the half past century, Tthe rate of warming in the globally mean surface temperature during the period fromcalculated since 1951 to 2012 was 0.012℃·a-1 globally. , Hhowever, the significant increasing rate in the TA (0.021 ℃·a-1) across the entire HRB was was about twice two time higher than the global average (Alexander et al., 2013), which is consistent with the findings of Sun et al. (2006), and Ren et al., (2005). also nearly. At the same time, the average warming rate was increased at a rate of (0.022 ℃·a-1) over the past 50 years in China (Ding et al., 2006), while an interesting phenomenon was observed in this study that
The main reason why I chose to research this topic and why it fascinates me, is mainly based on the fact that our society has convinced us that animal agriculture, which fuels meat consumption, is not responsible for most of our greenhouse gases. When in fact, numerous studies has proven that livestock, and the byproducts that come along with it are responsible for approximately 51% of all worldwide GHG emissions3. Along with that, I find it interesting that livestock is blameworthy “for 65% of all human-related emissions of nitrous oxide– a greenhouse gas with 296 times the global warming potential of carbon dioxide.”3 I found all of the information very interesting, but I had to see the application and actual data.

In the February 1st edition of the New York Times, journalist Andrew C. Revkin discusses the rising threat of global warming, and more importantly, the disagreement between various nations and institutions upon the definition of “dangerously high global warming.” Revkin’s article, titled “Deciding How Much Global Warming Is Too Much,” brings to light the various failed attempts at creating a barrier at which industrialized countries (the main producers of the greenhouse gasses which result in global warming) will cut the release of harmful gasses into the atmosphere. Revkin also discusses how upcoming events, conferences; reports will hopefully solve this problem.
Global Warming Global warming is an important factor because every one in the world but most importantly for me it will effect all of my relatives, as it is predicted that countries such as Bangladesh will be totally fooled due to global warming. Global warming interest me because the planet we live in is changing and the change that is happening will effect the way we live and how the future generations live. It has direct effects on the us and the relatives we have all over the, for ex This changes which will likely to alter the natural weather and climate patterns is largely because of human activities in the last century.
