Global Warming
As the world's expanding population burns large quantities of fossil
fuels and simultaneously cuts down large expanses of forests
worldwide, the concentrations of CO2 and other greenhouse gases are
building up in the atmosphere. "The green house effect is the
(imperfect) analogy used to explain the atmospheric phenomenon that
keeps our planet warm enough to sustain life." There is mounting
evidence that this shift in Earth's atmosphere will lead to global
changes and potentially major climatic disruptions. The major concern
is not that the greenhouse effect is real;"we wouldn't be here if it
wasn't." It is that it "may be exacerbated by anthropogenic increases
in the effective gasses, threatening a disruption to the equilibrium
between incoming and outgoing energy, and a resulting average global
warming." From 1880 to today, by many measurements, the global average
temperature has increased by 0.5 Degrees Celsius.
Human and ecological systems are already vulnerable to a range of
environmental pressures, including climate extremes and variability.
Global warming is likely to amplify the effects of other pressures and
to disrupt our lives in numerous ways. "Melting icebergs and expanding
oceans may cause floods." The Intergovernmental Panel on Climate
Change (IPCC) predicts that there will be an increase in sea level by
the year 2100 of 1.5 feet. "Twenty Five percent of the world's
population lives less than 1.1 meters above see level." The IPCC also
predicts that there will be "droughts, heat waves, expanding deserts,
ecosystem disruption and increasingly severe weather", as well as the
productivity of agriculture...

change would likely continue.
We can slow down the rate of atmospheric change by cutting back on the
amount of greenhouse gases we pour into the air. This will require a
considerable change in our fuel consumption, industrial practices and
lifestyles. Nevertheless, it is definitely worth the effort because a
slow alteration in global climate would be much easier to adapt to
than a fast one.
Uncertainties about global warming are so great that it is not
possible now to say whether the net result has been, or will be,
beneficial or harmful to forest growth and composition or to the
subsequent management and use of forest resources. The only
certainties are that: greenhouse gases are accumulating; that the
greenhouse effect is real; and that some future global warming is
possible as a result.
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.
It was a dark morning that Sunday, it was the 28th of August of 2005. Douglas and his family heard a storm was coming, so they went to his mother-in-law´s house, as they always did when there were storms. They were there, and Douglas went to the bay behind the house to check the level of the water. It was too high, and the wind was getting stronger, so he went to warn his wife, daughter, and mother-in-law. As he was heading back, the roof of the house collapsed. None of the three women survived. That is the story of one of the thousands of victims of hurricane Katrina in New Orleans. But, why do disasters with this magnitude occur? Hurricanes, for example, are caused due to the energy from water vapor coming from warm oceans. Oceans get warm because, when the atmosphere gets warm, air temperature increases and oceans absorb this heat. In the end, it all came down to the atmosphere.
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.
Climate change is neither new nor unusual. Throughout the history of the earth, the average surface temperature, climate and greenhouse gas concentrations have changed, sometimes gradually other times quite sharply. During the past 10,000 years the earth has been in an interglacial period with a fairly stable climate, surface temperature, and greenhouse gas concentration1. The problem that has arisen in recent times is when scientists analyze the past 150 years, especially the last 50. Scientists have found an increased greenhouse gas concentration, making the 20th century the hottest in the last 10,000 years.
Global warming is a major problem around the world that many people choose to remain blind to. This disaster is effected many ecosystems like the polar ice caps and ocean currents. Global warming is affecting humans more than you think a little extra heat could cause. Unfortunately, this problem cannot be fixed but there are simple things that you can do to help slow down the slow process.
problems due to global warming are death to heat waves and other climate changes, and
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.

“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.
As we all know, Global Warming has become a major scientific and social issue during the past decade. Global Warming - the increase in greenhouse gasses- has captured broad public attention because it would easily damage the nature and many souci-cultural aspects of life. That's why it should be investigated thoroughly. In the following essay, I will introduce you to the different approaches of some writers and state their possible answers to this global problem.
