An essay on global warming and climate change for
Answers
Global warming is the scientific phenomenon linking an increase of the average earth temperature because of a trapping of radiation within the earth like a greenhouse.
Global warming is caused by an acute heating of the earth’s atmosphere as a result of energy being trapped. Greenhouse gasses such as carbon dioxide and methane can cause the atmosphere to build up, leading to solar radiation becoming trapped within the earth like within a greenhouse, hence the name.
The phenomenon of global warming has been occurring naturally as a result of the natural rotation of the sun which changes the intensity of solar radiation hitting the earth, also natural processes such as volcanoes produce a large amount of Sulphur dioxide and other greenhouse gasses which can result in global warming too.
Global warming is also largely a result of the release of methane from cracks in the earth, landfill sites and through natural gas leaks. Methane has an effect on the atmosphere which is four times as bad for global warming as carbon dioxide.
The reason as to why global warming is such an issue today is because of the problem that humans are creating with anthropogenic contributions to greenhouse gasses. Modern technology and new lifestyles have resulted in human activities that produce a lot of greenhouse gasses such as deforestation, the combustion of fossil fuels, industrial action and farming animals.
The growing rise of industry around the world and the rise of consumerism has resulted in the production of many goods, all using fossil fuels either directly or indirectly.
Deforestation is one of the biggest causes of global warming. Not only are trees cut down to make goods that need to be transported using fossil fuels, the removal of trees leads to a net loss of photosynthesis which is carried out by plants to make food. The wide scale removal of trees and biodiverse life results in a large amount of carbon dioxide that can’t be converted to oxygen and so a huge problem for global warming. Polar ice caps can melt, there will be widespread flooding all over the world, there will be an increase in the frequency and intensity of harmful natural disasters and the consequences to the economy will be detrimental to societal progress.
The melting of polar ice caps poses one of the biggest problems for human society. As the earth’s temperature increases, these large masses of ice and snow will melt and create the sea level to rise all over the world. In the same way, glaciers will also melt and create problems on land. According to scientific research, if all the snow and ice were to melt today, this would result in a raised sea level of over 200 feet worldwide and would be instantly detrimental to many low lying areas such as the Netherlands and other low lying islands around the world. It is the tragic case that most of the countries and areas that will be affected directly are often the ones that contribute the least to global warming. .
Natural disasters such as hurricanes will be of greater occurrence and this will cause an increase in the economic effects. Hurricane damage alone will result in billions of dollars worldwide needing to be spent to rebuild societies and provide relief. It will be difficult for people and societies to keep up and offer enough support if global warming is too big of a problem. All natural disasters from tornadoes to droughts will all increase in intensity – one can only imagine what a hurricane twice as strong would do!
In conclusion there are many causes and effects of global warming. Problems will exist unless hard geoengineering is developed or if people are given sufficient incentives to change their actions for the better.
Answer:
Explanation:
Global warming
Global warming is a part of climate change and is partially caused by increased greenhouse gases from burning of fossil fuels, deforestation, agriculture, and other industrial causes.
The Earth's temperature had already warmed by 1°C compared to pre-industrial levels. This temperature rise may appear small, but small rises in temperature translate into big changes for the world’s climate. This is because the amount of extra energy needed to increase the world’s temperature, even by a little, is vast. This extra energy is like force-feeding the global climate system.
·Hotter days
·Rising sea level
·oceans are warming
Melting glaciers, early snowmelt, and severe droughts will cause more dramatic water shortages and increase the risk of wildfires in the American West.
Rising sea levels will lead to coastal flooding on the Eastern Seaboard, especially in Florida, and in other areas such as the Gulf of Mexico.
Allergies, asthma, and infectious disease outbreaks will become more common due to increased growth of pollen-producing ragweed, higher levels of air pollution, and the spread of conditions favorable to pathogens and mosquitoes.
