Argumentative essay about the greenhouse effect​
WINSTONCH [101]
The purpose of this essay is to explain what the greenhouse effect is and how it operates. It will also discuss the sources of the greenhouse effect as well as the ramifications of this phenomenon. The term "greenhouse effect" refers to the fact that heat from the sun enters the Earth's atmosphere and is unable to escape, resulting in heat being retained.
It was given this name because it resembles a greenhouse in many respects. When short wave radiation from space meets the Earth's surface, it is transformed into long wave or infrared radiation, causing this effect to manifest itself. Heat energy in this form is subsequently absorbed and stored in the atmosphere as water vapour and carbon dioxide, which are both greenhouse gases. The greenhouse effect is caused by a wide range of factors. The amount of carbon dioxide in the atmosphere is raised as a result of the presence of O.

Because of the tremendous usage of fossil fuels such as oil, coal, and natural gas, the global population is growing at a rate of 4 percent each year. Another element is the amount of forest that is harvested; every second of the day, an area of forest the size of a football field is stripped of trees, either by being logged or by being burned. Methanol and chloroflourocarbons are two more hazardous greenhouse gases that are entering the atmosphere at a rate that is even quicker than carbon dioxide, despite the fact that they are not as harmful in the long run. These increases will almost certainly have a significant impact on global temperatures. Assuming that greenhouse gas emissions continue at their current rates, the average temperature for most parts of the world will rise by 2 to 6 degrees Celsius in the next 100 years.
This increase in temperature would have a significant impact on the growth of many different crops, as well as induce the melting of the polar ice caps, which would result in sea levels rising by several metres. If this rise in sea level were to occur, many regions would be far more vulnerable to flooding, with floodwaters generally being much deeper than would be expected today. This flooding would occur primarily in coastal locations around the world, as well as along many rivers that run to or from coastal inlets, according to the World Bank.
The greenhouse effect is extremely important because it causes rising water levels and temperatures, both of which have the potential to have a significant impact on the world's climate.
Climate change has the potential to cause big changes in agricultural industries. This can result in good farmland becoming desert, making it too hot for some crops to grow, or allowing pests and illnesses to flourish. As a result, certain countries may experience poor economic conditions, and people may be forced to relocate. Some low-lying countries, like as those on the Pacific Islands or Holland, could see a significant amount of dumping, necessitating the expenditure of significant funds to construct sea barriers and leveebanks to prevent flooding. As a result, it is critical to carefully regulate the greenhouse effect by reducing the amount of carbon dioxide released into the atmosphere and increasing the number of trees in the environment.

Which regions of Earth have the most variation in weather based on its alignment with the sun?
yKpoI14uk [10]
