English composition on how to deal with global warming
Global warming Global warming greenhouse effect leads to global warming Global warming "greenhouse effect" refers to a physical feature in the earth's atmosphere. Without the atmosphere, the average temperature of the earth's surface would not be 15℃ as it is now, but-18℃ would be very low. This temperature difference is caused by greenhouse gases, which absorb infrared radiation and affect the overall energy balance of the earth. Under the influence of greenhouse gases, the atmosphere absorbs more infrared radiation than it releases into outer space, which makes the surface temperature of the earth rise. This process is the "natural greenhouse effect". However, because human activities release a lot of greenhouse gases, more infrared radiation is refracted to the ground, which strengthens the role of "greenhouse effect". Global warming is an important topic in global environmental research at present. According to the systematic analysis of more than 100 global temperature change data, it is found that the global average temperature has increased by 0.3 ~ 0.6 degrees Celsius. The warmest year of 1 1 occurred after the mid-1980s, so global warming is an indisputable fact. Global warming will bring very serious consequences, such as glacier retreat, sea level rise, desertification and so on. , and have a serious impact on the ecosystem and agricultural production. Global warming may eventually lead to global cooling and form another ice age. Just like the terrible scene we saw in the American movie The Day After Tomorrow. Therefore, exploring the causes of global warming has become an important research topic. According to the analysis, although there have been many climate fluctuations in the history of earth evolution, the growth of atmospheric greenhouse effect caused by human activities may be the main factor. Governments, enterprises and scientists all over the world have gradually realized that we must take prompt action to deal with climate change. At present, people have taken measures to limit the emission of carbon dioxide. Many companies are actively responding to the era of carbon dioxide emission limitation. Global Warming The greenhouse effect of global warming leads to global warming. According to the data of the National Academy of Sciences, in the past century, the surface temperature of the earth has increased by about 1 Fahrenheit, and in the past two decades, the global warming rate has accelerated. There is new and stronger evidence that most of the warming in the past 50 years is caused by human activities. Human activities have changed the chemical composition of the atmosphere by accumulating greenhouse gases, mainly carbon dioxide, methane and nitrous oxide. The endothermic characteristics of these gases are indisputable, although the response of the earth's climate to them is uncertain. Energy from the sun drives the weather and climate of the earth and heats the surface of the earth; In turn, the earth radiates energy back into space. Greenhouse gases in the atmosphere, such as water vapor and carbon dioxide, intercept some released energy and retain heat, which is a bit like the glass panel of a greenhouse. Without this natural "greenhouse effect", the temperature would be much lower than it is now, and life as it is known today would not exist. On the contrary, due to greenhouse gases, the earth
