Global warming is the continuing rise in global average temperature specifically the temperature of the atmosphere and oceans. There are some hypotheses that the temperature has risen since the late 1900s century due to the human activity, mainly by emissions of carbon dioxide increased the greenhouse effect. The greenhouse effect is a natural process that traps some of the sun rays in the atmosphere to regulate the temperature of the earth. This happens when the rays enters in the atmosphere. There are some of the solar rays that was trapped by the greenhouse gases in the atmosphere naturally, and the rest goes to space.
Global Warming 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.
Global Climatic Changes Introduction: Climatic change is a lasting change in the weather patterns around average conditions. Certain factors like global warming, greenhouse effect, biotic processes are some of the reasons for global climatic change. The average global temperatures have changed and the precipitation patterns as well. Over the past century human activities led to increase in the emission of heat trapping gases like carbon dioxide. The average earth’s temperature has risen by 1.4° F and it is also projected to rise about another 2-13.5° F in the coming decades.
If there were no greenhouse gasses, very few rays would be absorbed and the earth would be extremely cold. When too many rays are absorbed, the earth?s atmosphere starts to warm, which leads to global warming. Global warming can lead to many problems that affects the environment in which we live. In order to talk about global warming, we must first learn what causes the greenhouse effect. A lot of the rays from the sun are absorbed by water vapor that is naturally in our atmosphere.
It is very difficult to reverse this process once it is started. If we want to live like we are now and have been we have to stop this process. Emissions of fossil fuels by humans is a big factor of global warming. The reason being is because of the amount of carbon dioxide released from the fossil fuels. Controlling these emissions is one huge step of many steps required to slow down and stop global warming.
The increases of these chemicals have enhanced the heat trapping capability of the atmosphere of the earth. Sulfate aerosols, cool the atmosphere because they reflect light back into space, but sulfates do not live long in the atmosphere. Scientists still do not know what exactly is heating up the earth. Some say the earth is going through a natural cycle because the earth has gone through cold periods as well as hot periods. Mounting evidence is saying that humans are to blame for the rise in temperatures over the past 120 years.
Some people believe that humans are causing it while others believe it is just another result of the trapped CO2 and methane. The Greenhouse effect, changes since the Global Warming and incorrectly presented statistics are all contradictions involved in Global warming. What is the Greenhouse effect? It is warming close to the earth’s surface that happens when the earth’s atmosphere locks in the sun’s heat. Infrared radiation is sent back into the atmosphere which is heat energy.
Global warming is an increase in the earth's temperature due to fossil fuels, industry, and agricultural processes caused by human, natural, and other gas emissions. This results in an increased evacuation of greenhouse gases. “Short-wave solar radiation sinks into the Earth's atmosphere and warms its surface while long-wave infrared radiation emitted by earth's surface is absorbed, and then re-emitted by trace gases.” (2) Climate changes occur in our earth's atmosphere due to a buildup of greenhouse gases. Greenhouse gases can occur naturally as well as a result of human activities. The greenhouse gases are carbon dioxide, methane, and nitrous oxide.
So, some heat is kept in the atmosphere (CEOSR 1). That’s why the earth keeps warm constantly. // However, the climate is changing from human activities, which have greatly increased greenhouse gases. We call this change global warming. Global warming is a phenomenon in which the earth’s temperature rises from an increase of carbon dioxide or other greenhouse gases.
It can also enter the atmosphere from natural gas fields and coal mines. There are various sources of nitrous oxide including the use of fertili... ... middle of paper ... ... We as a world community need to seriously do something drastic to slow down the process of global warming, otherwise we may find ourselves in a situation where we can't turn back the hands of time and we're suffering because of Global warming. We need to make sure that future generations can live a happy and uncomplicated life; they shouldn't have to suffer from the impacts of Global warming that we (the current generation) have mostly caused.
