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 absorb heat, which makes them
vibrate. They eventually release the heat energy and it is often
absorbed by another greenhouse gas molecule.
The greenhouse effect is useful because trapping some energy keeps the
temperatures on our planet mild and suitable for living things.
Without its atmosphere and the greenhouse effect, the average
temperature at the surface of the Earth would be zero degrees
Fahrenheit. However, too many greenhouse gases can cause the
temperature to increase out of control. Such is the case on Venus
where greenhouse gases are abundant and the average temperature at the
surface is more than 855 degrees Fahrenheit (457 degrees Celsius).
We have increased the amount of carbon dioxide in the atmosphere by
burning fossil fuels, such as coal, oil and petrol. Cows, rice fields
and rubbish rotting in landfill sites produce methane, and aerosols
and fridges use CFCs.

The theory for these rapid rises and falls of temperature, based on
the geological records from 55 million years ago, is that gradual
global warming due to some natural cause had resulted in temperatures
5 to 7 degrees centigrade higher than average ( i.e. higher than
today's temperatures). At this point methane trapped in methane
hydrate deposits started to be released into the atmosphere and
accelerated the rate of warming. This would result in further warming
releasing more methane. As the atmosphere warmed different types of
methane deposits would start to be released and so a cycle of methane
release leading to increased warming leading to more methane release
from other areas of methane deposits elsewhere in the world would
become established as global warming effected different areas of the
world.
Global warming is the rise in average temperature of Earth’s atmosphere and oceans. If the warming continues it will have drastic effects on our lives in the future. Things such as harsher summers and colder winters will become a reality for future generations. Global warming is real, despite what the naysayers say, and it will affect us in many different ways if we can’t solve this problem. By presenting skeptics arguments about global warming I’ll prove global warming to be real by disproving them.
In this essay, the effects of climate change on agriculture and how to manage it shall be discussed. Climate change has and will greatly affect agriculture. As time progresses, the effects of climate change will worsen and become detrimental. Mendelsohn and Dinar (2009:1) state,” if future climate scenarios lead to a widespread reduction in food supply, there could be massive problems with hunger and starvation”. Climate change is a change in global climate patterns which is mainly caused by the increased levels of atmospheric carbon dioxide produced by fossil fuels. The writer chose this topic because climate change is a global problem that will pose a threat to people’s lives around the world and must be dealt with sooner than later.
For years to come there will always be a speculation on whether the climate change has really taken place or not. Many believe that large companies launched this topic in order to benefit from it in profit, as there are also those who are convinced that this are consequences that have emerged from human mistakes in understanding the environment. As humans are struggling to trust one another whether it is just a big conspiracy or not or environment changing itself, we are slowly starting to feel the effects of climate change. Because of the gasses (CO2) that are in the air, atmosphere is getting warmer, thereby triggering the Greenhouse effect. Almost 70% of emitted gasses in air are CO2, which leads us to believe that this is the main cause of Global Warming. Since it is billions and billions of metric tons per year that are being released in air, many scientists conclude that temperature will most likely be more higher in twenty years from now, than it was in near past.
over the past century primarily due to green house gases released as people burn fossil
Hong Kong nowadays has a major problem on global warming due to climate change. Climate problems may not take up any awareness among people in today’s society. Humans are responsible for many of the climate problems we are facing. Climate changes naturally and the current trend of global warming started before the industrial revolution. Before the climate change the climate was a lot warmer. Weather and temperature could be one of the major issues that affects global warming and climate change.
The main gases that cause the greenhouse effect are water vapor, carbon dioxide (CO2), and methane, which comes mainly from animal manure. Other gases like nitrogen oxide and chloroflurocarbons, man made gases, get caught in the atmosphere as well. The decay of animals and respiration are two main natural sources of carbon dioxide. In my opinion, we the people of the world should try to slow down the emission of greenhouse gases and/or find ways to balance the gases so the climate doesn’t change so rapidly. If it did, we would be forced to adapt to the new climate that we brought upon ourselves. If we had an international cooperation to put a damper on the production of chloroflurocarbons and slowed down the use of fossil fuels it would dramatically slow done the process of "global warming". Carbon dioxide pollution from the increase of industry and transportation is a major cause of global warming. These two causes are connected with the growth in the world population. As the population grows the necessity for food and other products increase, therefore industry must grow to keep up with the demand. The increase in transportation is directly due to the growing population and the need for jobs and the growing congestion on our highways. Another cause in global warming is deforestation. Trees remove carbon dioxide from the air as they grow. The carbon dioxide is released back into the air as they are cut and burned. The forest ability to reduce the carbon dioxide from the atmosphere is decreasing due to massive deforestation around the world. These causes seem simple and fixable, but if they are not cut down, the Earth and its inhabitants will feel the effects.
What happens when too much carbon dioxide gets omitted into the Earth’s atmosphere? The condition known as Global Warming occurs. Global Warming is the rising of the Earth’s surface temperature due to chemicals in the atmosphere. Global Warming has many threats on the climate and even the health of the people on this planet. Some of these threats include the altering of crop seasons and even effect the way organisms survive on the planet. The first thing I think I should discuss when talking about global warming is what causes it to occur.
Two issues that worry many scientists are global warming and the greenhouse effect. The greenhouse effect is a natural process that keeps the earth at temperatures that are livable. What does the greenhouse effect have to do with global warming? When humans release gases into the air, the greenhouse effect will alter the temperature of the earth. More gases in the atmosphere means the earth will start to get warmer, and the result is global warming. On the other hand, if there was no greenhouse effect, the earth would be too cold for humans to comfortably exist.
Global warming is the rising of average temperature of the Earth’s atmosphere due to greenhouse gases. Greenhouse gases are gases that trap heat in the atmosphere. The greenhouse effect consists of gases such as carbon dioxide, methane, nitrous oxide, and water vapor insulating the Earth’s surface and helping it maintain warm temperatures. However since there is so much carbon dioxide filling the air the Earth atmosphere absorbs almost all of the suns emission. When the sun heats the earth the atmosphere is supposed to radiate most of the heat but instead it takes all the warmth and uses it to power the Earth causing a buildup of green house gases. This has been taught to everyone, but is it true or a hoax? Some scientists argue that global warming is nothing to worry about and that it is just a myth. Nevertheless there are other scientists who say the world will enter a vast drought because of the rising temperatures. Global warming affects natural and geographical and historical boundaries.

Global warming has become a world wide issue and an issue that is causing great controversy. It is an increase in the earth's atmospheric and oceanic temperatures widely predicted to occur due to an increase in the greenhouse effect resulting especially from pollution (Dictionary). Global warming is a natural process, but because of increase in certain activities this process is taking a faster and more dangerous route creating global problems. Global warming was first theorized in 1894 by Jean Baptiste Joseph Fourier a French mathematician, who noticed the earth was gradually increasing in temperature. He came to the conclusion that the earth’s atmosphere was trapping solar radiation caused by the sun and reflecting this radiation back to earth (History of Global Warming). This theory by Fourier became known as the “greenhouse effect”. In simpler terms the greenhouse effect is where the temperature rises because the sun’s heat and light is trapped in the earth’s atmosphere. In the past one hundred fifty years the average global temperatures have taken a sharp turn upward. The 20th century’s ten warmest years all occurred in the last fifteen years. Also the 20th century was the warmest globally in the last 600 years (Global Warming and Carbon Dioxide, 3). Effects of this increase are the melting of glaciers, rising sea levels, more frequent heat waves and droughts, and heavy rainfall. The burning of fossil fuels such as coal and oil are a main source to why the greenhouse effect is being enhanced and likely contributing to global warming (Global Warming and Carbon Dioxide, 4). To hinder this increase in the global warming process we must reduce CO2 emission, we have to use different sources of energy, and we must recycle.
“The global warming is refers to the global temperature to elevate.”( Philander, S. George, P456). According to Global Warming and Climate Change, nearly 100 for many years, the global average temperature has experienced the cold - warm - cold - warm two fluctuations, generally speaking for trend of escalation. After the 80s, global temperature obvious is rising. What’s the global warming? Global warming is a growing problem in the world. Melting ice-caps in the Artics and Antartica, rising temperatures across the continents, increasing number of typhoons and tropical storms are just some of the effects of global warming. It must be realised that human activities are the causes of global warming. The increasing levels of carbon dioxide (CO2) have rose at exponential rates. It is therefore our duty to save the earth. Nowadays global warming is big deal with human especially in Asia, which is much more problems in population, environmental pollution and industrial pollution.
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.
There is little doubt that the air’s carbon dioxide concentrations have been increasing since the Industrial Revolution and there are few who do not attribute this increase to the rise in humanity’s use of fossil fuels. There is also little dispute that the earth has warmed slightly over the same period. During our interview Adam told me that he believes strongly in the dangers of global warming and feels great animosity towards critics of this theory. Our conversation had an angry tone as Adam explained his hostility towards those who “say that there is no compelling reason to believe that the rise in temperature is caused by the rise in carbon dioxide.” I spent the entirety of the interview trying to explore why Adam exhibited such strong resentment towards global warming's critics and why he felt so passionately about this topic.
Global warming changed from a scientific topic to a real life concern in 1988 and is a topic that proposes everlasting environmental issues. Some countries are already seeing the effects that global warming can cause, not only will the temperature increase causing ice caps to melt and many animals becoming extinct but it’s the way global warming is happening that will really impact the environment. This problem mainly started to rise due to the Industrial Revolution. When more and more factories were built gases were released into the atmosphere and the main gas that causes global warming is the ever-growing amounts of carbon dioxide (CO2). As the world becomes more urbanized the more the crisis of Global Warming increases.
