Global Warming & Its Effects1
Nicolas Dalleva
simple是什么意思1 Each year the United States spends over 20 million dollars buying fossil fuels. This country emits one fourth of the world’s greenhou gas; the most prominent of the gas is carbon dioxide, which is relead from the burning of fossil fuels. Global warming has been a global issue for many years now. Some countries and people claim to be only vaguely concerned with the cau becau they were unaware or uninformed of the issue. Roger Revelle2, an oceanographer, helped to call out the problem to the public. After not receiving much feedback towards his cau, he criticized different governments in a jocular manner. He called warming “the great geophysical experiment.” He said, “The experiment is to load the atmosphere with as much carbon dioxide as possible, add a few other harmful gas, and e what happens.” Recently, veral countries have been passing laws to prevent the world’s overheated destiny. Even with the tting of new rules and regulations, the earth continues to warm each year. Minimal efforts made to reduce the relea of greenyqq
hou gas, specifically carbon dioxide from the burning of fossil fuels, increa the rate and intensity of global warming.
2 The most prominent effect of global warming exists in the climate change over the past years. Many people are unaware that global warming caus and changes all types of weather. The heating of the earth caus the magnitude and strength of weather conditions to increa. As the oceans get warmer, the intensity of hurricanes amplifies in power and devastation. In addition, many costal cities and regions have recently been experiencing flooding, caud by the melting of the polar icecaps. The Arctic’s perennial icecaps decline in area by nine percent each year. In the past thirty years, over ten national records were t for the highest temperatures in the summer and winter. Droughts and forest fires have been occurring dramatically more often in the past century. 【All of the effects have been directly linked to the relea of greenhou gas.】
3 【Another area affected by global warming is the animal kingdom and nature.】 The nu
mber of animals per specie has been decreasing annually due to harsh environmental changes. As the polar icecaps melt, all creatures that live there are left without shelter. For example, as al dens have been melting, the number of als has dropped. Events that occur in the spring, such as mating, migrating, laying eggs, and returning from hibernation have been taking place approximately 5.1 days earlier than they were fifty years ago. The early occurrence of the events proves that the earth is getting warmer each year. More proof of warming is the evidence of many animals traveling farther from the equator as they migrate. Although this change has been occurring with various creatures, butterflies and mosquitoes are being found the farthest from their natural habitats. Even though butterflies do not cau any known problems with the environment, mosquitoes are carries of malaria. This deadly dia has dangerously spread to new regions across the globe. If the world continues to warm, this issue, along with many others, will continue to grow.
4 【ielts培训A third type of evidence of global warming can be found in plants. 】Vegetation in an area differs concurrently with the climate of that same area. Throughout many parts of the
world, flowers bloom 7 days earlier and trees reproduce 10 days earlier, both since 1900. As the growing asons vary from very wet to very dry, agricultural growth cannot adapt. In some recent years, regions’ crops have been both flooded and dried out. Due to the depletion of the ozone, many crops cannot survive. Another problem is the movement and increa of allergens. Carbon in the atmosphere allows plants to go through photosynthesis more rapidly, allowing allergens to grow in number. This evidence found throughout all of nature makes it very clear that global warming is a huge issue.
5 A combination of various actions and, in some cas, not enough action caus global warming in the world today. 【The leading cau of global warming is the ongoing burning of fossil fuels, which releas carbon dioxide into the atmosphere. Carbon dioxide, along with the other greenhou gas of methane, nitrous oxide, and chlorofluocarbons, is the cau of the greenhou effect. 】This effect is dangerously increasing as the gas are being relead in greater quantities. The gas not only build up to keep heat in the atmosphere, but they also thin the ozone layer. Some areas have been so thinned by the gas that there are holes prent in the ozone. The dang澳际留学中介
erous holes allow harmful UV rays3 from the sun to reach the earth. UV rays are the main cau of skin cancer. As the earth continues to increa its pollution level each year, the number of skin cancer patients increas.
英语有道在线翻译6 Becau it releas carbon dioxide into the air, the burning of fossil fuels is an environmentally harmful practice. Carbon dioxide can be absorbed by awater. If the water is cold, it can hold more gas. Unfortunately, with global warming, the temperature of the oceans has been increasing. As the temperatures increa, more carbon dioxide is relead. This vicious circle will continue to occur unless scientists cannot this from occurring. Particularly, petrol, or gasoline, is a leading source of the relea of the carbon dioxide compounds. Petrol contains hydrocarbons that relea carbon dioxide when they are burned. This reaction is unfortunately unavoidable. The only solution is a different fuel source. Carbon dioxide, once relead, lasts up to 100 years in the atmosphere. It is the most abundant heat-absorbent gas besides watervapor, which is not considered as a greenhou gas becau it rains back to the earthdew in a continuous cycle. The Mauna Loa Obrvatory4 has been measuring the level of carbon dioxide daily since
脱缰之马1958. Since their rearch began, the level in the atmosphere has drastically incread by 47 parts per million. 【doiteCarbon dioxide makes up about one half of the caus of global warming.】patch是什么意思
