essay on global warming
Answers
Explanation:
A couple of decades back, global warming was more of a prediction rather than a happening. Sadly, we don’t have the luxury of saying so now because it’s a problem currently facing the whole world. To fight it requires everyone’s efforts including from the non-believers. In definition, global warming is the rise in temperature of the earth because of an increase in greenhouse gasses trapped within the ozone layer. The ozone layer is a blanket, invisible to the naked eye that surrounds the earth's atmosphere trapping radiation. Although it's a natural phenomenon, it has grown to be a problem in the last couple of centuries because of an anthropogenic rise in the GHG (Greenhouse gases).
The average temperature is rising everywhere on earth. The winters become colder and the summers are unbearably hot. The main reasons will be discussed further in detail but the major among them is human activity itself. We produce insane amounts of chemicals that affect our climate and make greenhouse effect impossible for the planet to recover from.
The grim reality we face is that if no action is taken, the world will cease to exist as we know it. Global warming is real, and its effects have proven by the scientific community. Although as mentioned before, there are non-believers who don't see the truth in the concept. If no action is taken these effects are bound only to get worse. Luckily, advancement in technology and conservation efforts are pushing for the change and protection of the earth. Essays on global warming serve the purpose of enlightening students of the serious problem that we as the world are currently facing. Having an understanding of what global warming is, is a critical part pushing them towards taking action at an individual and even community level.
Explanation:
Global warming is a slow and steady rise in Earth's surface temperature. Temperatures today are 0.74 °C (1.33 °F) higher than 150 years ago. Many scientists say that in the next 100–200 years, temperatures might be up to 6 °C (11 °F) higher than they were before the effects of global warming were discovered. Most noticeable changes by this increase in temperature is the melting of ice caps all around the world. Sea level is rising steadily as a result from continental ice melting into the sea. As a prediction, many cities are soon to be partially submerged in the ocean. Consequently, many part of the world have a major increase in temperature.
Among the Greenhouse gases, the concentration and increase of carbon dioxide in the atmosphere appears to be the main cause of global warming, as predicted by Svante Arrhenius a hundred years ago, confirming the work of Joseph Fourier more than 200 years ago. When people use fossil fuels like coal and oil, this adds carbon dioxide in the air. When people cut down many trees (deforestation), this means less carbon dioxide is taken out of the atmosphere by those plants.
As the Earth's surface temperature becomes hotter the sea level becomes higher. This is partly because water expands when it gets warmer. It is also partly because warm temperatures make glaciers melt. The sea level rise causes coastal areas to flood.Weather patterns, including where and how much rain or snow there is, will change. Deserts will probably increase in size. Colder areas will warm up faster than warm areas. Strong storms may become more likely and farming may not make as much food. These effects will not be the same everywhere. The changes from one area to another are not well known.
People in government and Intergovernmental Panel on Climate Change (IPCC) have talked about global warming. They do not agree on what to do about it. Some things that could reduce warming are to burn less fossil fuels, adapt to any temperature changes, or try to change the Earth to reduce warming. The Kyoto Protocol tries to reduce pollution from the burning of fossil fuels. Most governments have agreed to it. Some people in government think nothing should change. The gas produced by cows digestion also causes global warming, because it contains a greenhouse gas called methane.
