Consequences of GlobalWarmingGlobal warming is considered as the long term heating of the earth’s climate system. This phenomenon is observed since the pre-industrial period, which is between 1850 and 1900. Global warming is caused due to human activities like burning of fossil fuel and extraction of harmful gas into the air, which increases the amount of greenhouse gas present on-air. Greenhouse gases are considered as heat-trapping gases, and they block the heat inside the earth’s atmosphere, causing the temperature to rise. Here are some essays based on the topic‘Consequences of Global Warming’ of varying word length that might help you in the exams.Short Essay on Consequences of Global Warming 150 Words in EnglishGlobal warming is considered as the cumulative rise in temperatur e of the earth’s atmosphere at an alarming rate. This rise is getting witnessed for an extended period of time. It is caused due to the increase in the level of greenhouse gases in the atmosphere. These gases have the ability to trap heat on earth and increase the temperature of the atmosphere, which is causing global warming. The sole reason for thisincrease in greenhouse gases is human activities like deforestation, harmful gas extraction from automobile and industries, burning of fossil fuel and many other reasons. Humans are exploiting the natural resources of the environment, which is why they are facing such trouble.Global warming has some horrifying consequences which can affect human life. Natural disasters like hurricanes, floods, etc., are caused due to global warming. Many people face many challenges and hardships after these disasters. Glaciers are melting due to theincrease in temperature, which can cause an increase in the water level of earth, which is not a good sign for our future survival.Keeping all this in mind it is better to start taking steps towards controlling the global warming so that the earth’s temperature will come to a normal stage and people will be saved from all the future disasters that might happen if we keep ignoring the effects and consequences of global warming.We are not unaware of the fact that the temperature of the earth is increasing every year and at some point of time in the future it willbecome impossible for us to survive in this temperature. The only reason for this temperature rise is global warming. Global warming is caused due to the increase in the level of greenhouse gases like carbon dioxide, carbon monoxide, nitrogen oxide, etc. in the earth’s atmosphere. These gases are getting released into the atmosphere because of various human activities. Many harmful gases are getting released into the atmosphere every day, which is polluting the air around us.Every year we are breaking records in touching the highest temperature so imagine earth’satmosphere after 20 more years. We have started seeing the consequences of global warming such as forest fires, droughts in different places due to lack of rainfall, floods, hurricanes and many more natural disasters. These disasters are making human Life difficult. In last some year, the world has seen many deaths of living organisms due to these natural disasters.The water level is rising due to the melting of glaciers in the north and south pole, which is dangerous for the future. Due to global warming, oceans are becoming warm and acidifying,which is causing harm to water bodies living in the oceans. Unless we are taking some strict steps to control global warming, it is impossible to avoid such disasters.There is still time for humans to realise their faults and try to rectify it by controlling the emission of harmful gases into the air. This will somehow decrease greenhouse gases in the atmosphere; thus, the temperature of the earth will drop. This can give some hope for human survival in the future or else it will gradually become impossible to survive on earth.Long Essay on Consequences of Global Warming 500 Words in EnglishGlobal warming is a term that everyone must have heard of because it has become one of the earth’s biggest problems. Global warming is the gradual rise in the temperature of the earth’s atmosphere. This temperature rise is caused due to various activities that are taking place on earth. It has become a serious danger and needs some attention as soon as possible. Global warming is not caused due to one single reason, but there are several causes that areresponsible for it. Global warming is caused due to both natural and man-made reasons.Natural disasters like volcanic eruptions cause global warming because it releases tons of harmful gases into the atmosphere that pollutes the air. Air gets polluted when there is a rise in the level of greenhouse gases in the atmosphere. This gases are harmful and trap heat which causes the temperature to rise. Some human-made activities that are causing global warming are the emission of toxic gases, excessive use of the automobile, burning of fossil fuels, deforestation, etc. If these human-made activities are not controlled, then it can harm the atmosphere, which is not suitable for survival.The earth is facing a lot of consequences for global warming. The earth’s atmosphere is deteriorating each day, and no one cares. People are still doing the same things that are causing harm to the atmosphere, even if they are aware of the consequences. Earth is facing an increased number of natural disasters like flood, hurricanes, drought, landslides, etc., and all this is the effect of global warming. Due to the increase in temperature for global warming,glaciers are melting, which will cause an increase in the water level, which will result in a flood. Forest fires which are caused due to the high temperature of the earth’s atmosphere are destroying flora and fauna. Recovering from all this destruction is not easy.Global warming with the passage of time will start affecting the survival of human beings on earth, so before this happens, it’s better to buckle up and try things that can stop or control this global warming. There are many ways to prevent this rise in temperature, so we need to execute that in order to control it. It’s time to takeglobal warming seriously or else the future of humans on earth is in danger. Global warming should be stopped or controlled as soon as possible.We are all aware of the climatic change that the world is witnessing from the last few years. Our climatic system depends on the wind pattern, humidity, atmospheric pressure and temperature of the earth—different areas in the world experience different types of climate such as dry, moderate or tropical. Now the climate is changing in a weird way; for example, in rainy seasons, we are experiencing heat which showsthat there is a disruption in the atmosphere or the environment around us. The sole reason for such disruption is the increase in global warming. To live a healthy and secure life, it is mandatory to start taking steps to control the rise of global warming.According to research, it is proved that the temperature of earth has increased one degree Celsius in recent years. Many will think that this small increase is manageable, but no one is aware that this small change can bring massive consequences upon us. And the temperature is increasing every year, each day is getting hotterthan the previous day so just imagine earth after 20 more years, it will become a place where humans can’t survive. So this increase of one degree Celsius should be considered a waking alarm for us to take steps in controlling global warming to stop the upcoming consequences.Every year we are breaking records by experiencing the highest amount of heat. This is not a good sign for our survival. People will start dying from different diseases because of this heat. The extreme conditions are becoming the reason for many natural disasters which are destroying our atmosphere as well as theenvironment. Natural disasters like hurricanes, drought, flood and forest fires are becoming common for some areas of the world. If immediate steps are not taken then, these disasters might wipe out whole cities or regions. For instance, you must have seen the destruction caused due to Amazon forest fires. A lot of animals died in this incident. Many people are predicting that this will happen continuously if global warming is not put under control.Another consequence of global warming is the melting of ice caps and glaciers. This melting will cause an increase in the water volume ofdifferent oceans. Due to this reason, people are witnessing a rise in the sea level also. So it is clear that with the increase in temperature, the glaciers will melt and put the low lying areas in danger. Coastal cities will also come under the danger level category.Due to global warming, ocean water is getting warmer, which is causing trouble for the water bodies living in the ocean. This put the water bodies in danger, and they might suffer a lot for global warming.Global warming is a phenomenon that the world is witnessing from years, but in present-day, theincrease in global warming is unimaginable, which has made it a big concern. If this phenomenon is not controlled, then it might turn the earth into a place where humans can’t survive.。

This can have a ripple effect on the entire food chain, affecting both ocean ecosystems and the people who depend on them for food and livelihood.In addition, global warming is causing changes in the distribution and behavior of species around the world. Some species may be forced to migrate to new habitats in search of cooler temperatures, while others may struggle to adapt to the changing climate. This can lead to the loss of biodiversity and the extinction of certain species.Overall, global warming poses a serious threat to the environment, ecosystems, and human societies around the world. It is important for countries to work together to reduce greenhouse gas emissions, invest in renewable energy sources, and take action to mitigate the impacts of climate change. By taking steps to address global warming, we can protect our planet for future generations.篇3Climate change is a pressing issue that has been affecting our planet for many years. With the increase in greenhouse gas emissions and global temperatures, the impacts of globalwarming have become more prominent and severe. Here, we will discuss some of the major dangers and risks associated with climate change.One of the most immediate threats of global warming is the rise in sea levels. As the Earth's temperature increases, ice caps and glaciers melt, causing sea levels to rise. This poses a significant risk to coastal cities and communities, as they are more susceptible to flooding and erosion. In addition, rising sea levels can also lead to the displacement of millions of people who live in low-lying areas.Moreover, climate change is also contributing to extreme weather events such as hurricanes, droughts, and wildfires. These natural disasters have become more frequent and intense due to the warming of the Earth's atmosphere. The devastation caused by these events can have a significant impact on human health, infrastructure, and agriculture, leading to economic losses and social disruptions.Another major concern of global warming is its negative effects on biodiversity and ecosystems. As temperatures rise, many species are struggling to adapt to the changing climate, leading to a loss of biodiversity and ecosystem services. This canhave cascading effects on the food chain, as well as on human livelihoods that rely on natural resources.Additionally, climate change is also exacerbating existing health problems and creating new ones. Warmer temperatures can lead to the spread of vector-borne diseases such as malaria and dengue fever, while air pollution from fossil fuel combustion can worsen respiratory conditions like asthma. The impacts of climate change on human health are wide-ranging and can have long-lasting consequences on vulnerable populations.In conclusion, global warming is a serious threat that requires urgent action to mitigate its impacts. By reducing greenhouse gas emissions, investing in renewable energy sources, and adopting sustainable practices, we can work towards a more resilient and sustainable future for our planet.

全球变暖负面影响英语作文

全球变暖负面影响英语作文Global Warming's Detrimental ImpactsThe issue of global warming has become a pressing concern for the international community in recent decades. The phenomenon, characterized by a gradual increase in the Earth's average surface temperature, is primarily attributed to human activities that contribute to the emission of greenhouse gases. These gases, such as carbon dioxide, methane, and nitrous oxide, trap heat within the Earth's atmosphere, leading to a cascading series of environmental and societal consequences. As the global temperature continues to rise, the world is facing a multitude of negative impacts that demand immediate attention and action.One of the most significant consequences of global warming is the melting of glaciers and polar ice caps. As the Earth's temperature rises, these massive ice formations are rapidly shrinking, causing sea levels to rise at an alarming rate. This poses a grave threat to coastal regions and low-lying areas around the world, where millions of people reside. Rising sea levels can lead to the inundation of entire communities, the displacement of populations, and the destruction of critical infrastructure, such as roads, bridges, and buildings.Additionally, the increased salinity of groundwater and the intrusion of saltwater into freshwater sources can have devastating effects on agriculture, water supplies, and ecosystems.Another pressing concern associated with global warming is the increased frequency and intensity of extreme weather events. As the climate becomes more unstable, regions around the world are experiencing more frequent and severe natural disasters, such as hurricanes, typhoons, floods, droughts, and heat waves. These extreme weather patterns can have devastating consequences, including the loss of human life, the destruction of property and infrastructure, the disruption of economic activities, and the displacement of entire communities. Moreover, the impacts of these events can be particularly devastating for developing countries, which often lack the resources and infrastructure to effectively respond and recover from such disasters.The impact of global warming on ecosystems and biodiversity is also a major concern. As the Earth's temperature rises, many species are struggling to adapt to the changing environmental conditions. Habitat loss, species migration, and the disruption of delicate ecological balances are just a few of the ways in which global warming is affecting the natural world. The loss of biodiversity can have far-reaching consequences, as it can disrupt the intricate web of life that sustains the planet's ecosystems and the services theyprovide, such as food production, water purification, and climate regulation.Global warming also poses a significant threat to human health and well-being. The increased prevalence of vector-borne diseases, such as malaria and dengue fever, can be attributed to the expansion of the habitats of disease-carrying insects due to changing climatic conditions. Additionally, the rise in extreme weather events can lead to the contamination of water sources, the spread of infectious diseases, and the exacerbation of respiratory and cardiovascular problems. These health impacts can disproportionately affect vulnerable populations, such as the elderly, the poor, and those with underlying medical conditions.The economic consequences of global warming are also far-reaching and complex. The costs associated with the mitigation and adaptation to climate change, the loss of productivity due to extreme weather events, and the disruption of supply chains and trade routes can have a significant impact on the global economy. Additionally, the depletion of natural resources and the degradation of ecosystems can have profound effects on industries such as agriculture, forestry, and tourism, which are heavily dependent on the health of the environment.In response to these pressing challenges, the global community hastaken steps to address the issue of global warming. The Paris Agreement, a landmark international treaty adopted in 2015, aims to limit the global temperature increase to well below 2°C above pre-industrial levels, with efforts to limit it to 1.5°C. This agreement has been widely ratified by countries around the world, and it has spurred the implementation of various policies and initiatives to reduce greenhouse gas emissions and promote sustainable development.However, the progress made thus far has been insufficient to adequately address the scale and urgency of the problem. Continued efforts are needed to further reduce emissions, promote the use of renewable energy sources, improve energy efficiency, and develop innovative technologies to capture and store carbon dioxide. Additionally, there is a pressing need to invest in adaptation measures, such as the construction of flood-resistant infrastructure, the development of early warning systems, and the implementation of sustainable land-use practices, to mitigate the unavoidable impacts of global warming.In conclusion, global warming poses a grave threat to the planet and its inhabitants. The consequences of this phenomenon are far-reaching and profound, affecting the environment, ecosystems, human health, and the global economy. While the international community has taken steps to address this issue, much more needsto be done to ensure a sustainable and resilient future for all. Concerted efforts from governments, businesses, and individuals are essential to reduce greenhouse gas emissions, adapt to the changing climate, and protect the planet for generations to come.。

全球气候变暖的危害1(Theharmofglobalwarming1)

全球气候变暖的危害1(Theharmofglobalwarming1)

全球气候变暖的危害1(The harm of global warming 1)There are two reasons for global warming: a large amount of coal, natural gas and so on produce a large number of greenhouse gases; wanton deforestation of virgin forests, so that the ability to absorb carbon dioxide decreased.The system of the atmosphere and the surface of the earth is like a giant "glass greenhouse" that keeps the surface temperature constant and produces an environment suitable for the survival of humans and other organisms. In this system, the atmosphere can not only let the solar radiation pass through the ground, but also prevent the loss of the ground radiation. The protective effect of the atmosphere on the ground is called the greenhouse effect of the atmosphere. Greenhouse gases are known as "greenhouse gases" that allow solar short wave radiation to pass freely and absorb long wave radiation from the earth's surface. These gases have carbon dioxide, methane, chlorofluorocarbons, ozone, nitrogen oxides and water vapor, among which carbon dioxide is the most important. The global climate has been warming up for the past 100 years, and meanwhile, the amount of greenhouse gases in the atmosphere has also increased dramatically. Many scientists believe that the greenhouse effect caused by a large amount of greenhouse gas emissions may be the underlying cause of global warming.Human activities that emit greenhouse gases include all fossil fuels, burning activities, and carbon dioxide emissions. In the fossil energy, coal was the highest, followed by oil, natural gas is relatively low; coal gas leakage in mining process of fossil fuel emissions of carbon dioxide and methane; cement, lime, chemical and other industrial production process ofcarbon dioxide emissions; paddy fields, cattle and other animal on anti digestion process of methane emissions from land use; changes to reduce the absorption of carbon dioxide and methane emissions; Nitrous Oxide.Human combustion of coal, oil, natural gas and trees produces large amounts of carbon dioxide and methane, which heats up the earth after entering the atmosphere, causing carbon cycle imbalances, and changing the energy conversion forms of the earth's biosphere. Since the industrial revolution, the carbon dioxide content in the atmosphere has increased by 25%, far exceeding the historical record that scientists have been able to survey over the past 160 thousand years, and there is no sign of slowing down.The main cause of global warming is that mankind has been using mineral fuels (such as coal, oil, etc.) for a century, emitting a large amount of carbon dioxide and other greenhouse gases. Because these greenhouse gases on the radiation from the sun wave through a highly, highly absorbent on the earth longwave radiation reflected, it is often said that the "greenhouse effect", leading to global warming.Forests in the world are divided into three types: boreal (boreal) forest, temperate forest and tropical forest. According to experts, today's forest ecosystem, is the nature of 8000 years of evolution is gradually formed.Today, all the virgin forests have become targets forlarge-scale exploitation of lumbering. In the tropics, many of the forests that have disappeared now have been cut off in thepast 50 years. Only from 1960 to 1990, there are more than 450 million hectares of tropical forest were swallowed, accounting for 20% of the total area of the world's tropical forests; there are millions of hectares of tropical deforestation, forest degradation in farmland reclamation and mineral exploitation.Moreover, the global illegal logging and illegal timber products trading continues to increase, especially in developing countries with tropical forests and Russia, which is poorly governed by the government. The demand for cheap wood products in the international market has further worsened the situation.The Intergovernmental Panel on climate change predicts that global temperatures will rise by about 1.4-5.8 degrees Celsius (2.5-10.4 degrees Fahrenheit) by 2100, according to climate models. According to this forecast, global temperatures will change dramatically over the past 10000 years, which has potentially significant implications for the global environment.HarmThere are about 40 small island developing countries and territories around the world. They are faced with many unfavorable situations, including the lack of resources, the isolation of the economy, the degradation of land and marine environment, and the possible rise of sea level due to climate change.At the request of the summit on earth issues, the United Nationsheld a global conference on sustainable development of small island developing States in Barbados in 1994". The conference stressed the economic and ecological vulnerability of small island developing countries, and adopted an agenda (Barbados agenda for sustainable development of small island developing countries). The agenda sets out the policies, actions and measures that governments and the international community need to support the sustainable development of these small island developing states.Zhang Piyuan, a researcher at the Institute of Geographic Sciences and natural resources, the Chinese Academy of Sciences, said: "global warming" has caused changes in the entire ecological environment. First of all, "global warming" lead to rising sea levels, rainfall redistribution, change the current world climate pattern; secondly, "global warming" destruction and influence of the chain and the food chain, causing more serious natural consequences. For example, there is a migratory bird who flies from Australia to Northeast China every summer. As the global warming increases the temperature in Northeast China and the summer is prolonged, the time of this bird leaving the Northeast becomes later, and the time to return to the Northeast will be delayed accordingly. As a result, a species of insect eaten by the migratory bird was flooded, destroying large tracts of forest. In addition, extreme events related to the environment, such as droughts, floods and so on, are increasing.Political restrictions on carbon dioxide emissions limit the consumption of energy, and will have a restrictive impact on the world. "Emission reduction" in developing countries, or"emission reduction" in developed countries has become the focus of discussion. As a developing country is a long body of children, need to consume energy to promote the growth of greenhouse gas emissions in developing countries continue to increase, in 2013 after the "emission reduction" problems will focus in developing countries. The scientific question of preventing global warming is bound to lead to the issue of "North-South relations", which has become an international political issue.The distribution of climate precipitation has also changed. The mainland especially the increase of precipitation in the high latitude areas, less precipitation in some regions of Africa. The occurrence frequency and intensity of extreme weather and climate events (El Nino, drought, floods, thunderstorms, hail, storms, hot weather and dust storms) in some areas are increasing.Ocean: as the global temperature rises, the amount of water vapor evaporated in the oceans has increased dramatically, exacerbating the warming phenomenon. The decrease of the total heat capacity of the oceans can also inhibit global warming. In addition, because the ocean releases excess CO2 into the atmosphere, the real culprit is the plankton community in the ocean.Impact of global warming on crop crop growth There are both advantages and disadvantages. First, the global temperature changes directly affect the global water cycle, causing droughts or floods in some areas, resulting in crop yield reduction, and the temperature is too high is not conducive toseed growth. Secondly, the increase of rainfall, especially in the arid areas, will positively promote the growth of crops. Global warming accompanied by elevated CO2 levels also contributes to crop photosynthesis and productivity.Global warming of clouds causes water content in the clouds to increase and absorb more infrared radiation. But scientists have also observed that tropical storm clouds rise to higher altitudes at higher temperatures, producing large amounts of rainfall, lowering the humidity in the troposphere and slowing the warming trend.The sea ice generally rise in temperature will accelerate the melting of snow and ice, increase water for the absorption of solar energy, but also contribute to global warming, sea ice will strengthen heat flux between air and sea, the lower the temperature.Human health (1) global warming led directly to parts of summer high temperature, because of heart disease and cause various diseases of the respiratory system, will take a lot of people's lives every year, with the greatest risk of neonatal and the elderly. (2) global warming causes ozone concentrations to rise, and low air ozone is a very dangerous pollutant that can damage lung tissue and cause asthma or other lung diseases. (3) global warming causes the spread of some infectious diseases.When the mosquito bites a person with an infectious virus, the virus will follow the blood into the mosquito body, begin to reproduce, and through the next bite into a healthy human body to complete the spread of the virus. In a certain temperaturerange, with the increase of temperature, the reproductive rate and biting rate of mosquitoes are greatly improved, and the virus reproduction and maturation rate will also increase. Night and winter temperatures rise, greatly extending the mosquito life and geographical areas, so that the spread of malaria, scarlet fever, jaundice, encephalitis and other malignant infectious diseases increased. (4) global warming will cause different natural disasters in different regions, directly led to food production, but also to the local residents suffered the threat of hunger and malnutrition, and will accelerate the diffusion rate of some water on the spread of the virus, such as encephalitis, dysentery, fever etc..。

下面,我们来看一下这篇听力原文告诉我们的那些全球变暖的危害。

Global warming may or not be the great environmental crisis of the 21st century, but—regardless of weather it is or isn't— we won't do much about it. We will argue over it and may even, as a nation, make some fairly solemn-sounding commitments to avoid it. But the more dramatic and meaningful these commitments seem, the less likely they are to be observed.全球变暖有可能是21世纪巨大的环境危机,也有可能不是,但是无论它是或不是我们对此都无能为力。

我们会争论不休,作为一个国家,或许会做出一些听起来相当认真的承诺来避免这一危机。

但是这些承诺看起来越是令人印象深刻、越是有意义,就越是不太可能被遵守。
