Recommended: effect of overpopulation to the environment
There are two major reasons of global warming: human factors and natural factors. They can be summarized as follows. The recent surge in population is one of the main factors leading to global warming. At the same time, it is also a serious threat to the balance between the natural environment. So much of the population, only a year of carbon dioxide emissions are staggering figure, the result will be a direct result of atmospheric carbon dioxide levels continue to increase, so the formation of carbon dioxide "greenhouse effect" will directly affect the Earth 's surface climate change . In addition, the increasingly serious air pollution constitutes a major climate issue, it is one of the main factors cause global warming. Now, research …show more content…
As we all known, good vegetative cover can maintain soil erosion. But much deforestation of human has damaged the forests environment in order to obtain timbers. Currently the world average of 20 hectares of forest per minute is destroyed 10 hectares of land desertification, 47,000 tons of soil erosion. Soil erosion decreased soil fertility and water retention, thus reducing the biological productivity of the soil and its ability to maintain productivity; and may cause widespread flooding and storms, causing significant economic losses to society, and deterioration of the ecological environment …show more content…
In AD 800--1200 , annual temperature in the North Atlantic region is now higher than 1 celsius degree, corn planting become possible in Norway. However, in AD 1500-1800, the Western Europe appear small ice age, average temperatures are lower than present only 1-2 celsius degree and caused half of Norway farm abandoned , the Iceland farming activities are almost stopped. In addition, global warming will have a bad effect on the stability and distribution of world food production (Effect of climate change on plant
Kenneth Hare reviews the scientific evidence on the greenhouse effect and explained that warming on global and increased greenhouse gases is the main issue that impact climate change. Human activity is the one who causes the greenhouse effect. The natural greenhouse effect is benefit to our world and become probable to making life on earth, but the temperature is very high nowadays that harm human, plant, and animal life. For example, the natural resource such as petrol for vehicles and electricity for our necessary needs will produce more than billions of carbon to the atmosphere every year that cause climate change every day in our earth.
We cannot dispute that automobiles, factories, and power plants, displace an unprecedented twenty tons of carbon monoxide - per person - per year. There needs to be a reduction in emissions, yet we cannot focus on this aspect of global warming alone. There are many indicators that climatic change is influencing the frequency and intensity of natural catastrophes. If scientific global climate models are accurate, the present problems will be magnified in the near future.
Nowadays, climate change is became a major global issue which are affecting our life such as global warming ,mean sea level changing and more extreme weather events etc .According to the research of Intergovernmental Panel on Climate Change 2007 ,it showed that the global mean temperature rose by 0.74 °C during the hundred year period from 1906 to 2005. Between 1956 and 2005,the rising rate was 0.13°C per decade in this 50 years , nearly twice the rate in the past 100 years. Eight (2010, 2005, 2003, 2007, 2006, 2009, 2012, 2004) of the last ten years (from 2003 to 2012) rank among the 10 warmest years on record. It seems that climate change is potentially affecting our life.In fact,human activities and natural effect are the causes of climate change.Generally,most of the scientists and government agree that human activities is the main causes of climate change rather than natural causes.Therefore,this essay is going to discuss why human activities change the climate more seriously than natural effect.Afterward,I will also present some possible solution to reduce the climate change.
Human induced climate change resulting from an enhanced greenhouse effect is probably the greatest environmental threat facing the world today. Specifically, the emission of greenhouse gases such as carbon dioxide may be classified as the primary culprit. As a result of greenhouse gases entering the upper levels of the earth's atmosphere, it diminishes or breaks down the earth's Ozone layer. With this loss of this protective blanket, harmful radioactive rays from the sun enter the deeper into the earth's atmosphere. This creates a rise in the overall temperature of our planet, along with alterations in the global environment, ecosystems and way of life for the habitants of earth.
The climate on the Earth is changing. Ice age is interleaved with the global warming. In the present age, the temperature of the Earth's climate system continue rapidly increase and it leads to global warming. Global warming is the process of gradual growth of average annual temperature of the atmosphere of the Earth and World ocean. The average temperature on the Earth was increased by 0.6C. There are various reasons of global warming, such as human activities, natural events, increasing of gases, such as carbon dioxide in atmosphere and solar activity (Global warming). Nearly 200 countries have signed Kyoto Protocol and they must reduce four greenhouse gases, in order to struggle with global warming. There are several perspectives about effects of global warming on environment. In this essay will be considered the impacts and consequences of global warming . In the process, it will be clarified that there are positive and negative impacts of global warming.
The increasing of global emission of CO2, a heat trapping gas is pushing the world into a crisis. CO2 or carbon dioxide traps heat in the atmosphere, which causes our world to have higher temperature. Seeing that the amount of burning fossil fuels gets bigger year by year, the global average temperature has also risen 1.4°F or 0.8°C. It can also lead to environmental such as mean health problems, destruction of problems, decreasing water and land pollution, etc. Moreover, as the ocean is affected by the carbon emissions, the ocean water becomes more acidic which causes loss of fish and other living organisms in the aquatic ecosystem and weakens the oceanic food chain. Furthermore, higher temperature causes heat and drought that damages the farms and ranches. If this keeps going on, the percentage of productivity and the yields of agricultural products will lessen since harvesting becomes hard when the land is in drought. By this, the price of commodity will also rise because of the declining yields of food crops, which would disadvantage the community. Other than that, because of CO2, it will cause melting ice and one of it is artic sea ice that begins...
Global warming and global climate change is the study of future increases of temperature across the globe. Studying climate change refers to how the over- all climate will change such as the dry places getting dryer and the wet places getting wetter. Global climate is dependent on “the greenhouse effect a natural process that helps regulate temperature” (Easterling and Karl). In the past few centuries humans have had a monumental effect on increasing of greenhouse gases in the atmosphere. Climate change is result of the increase amount of the greenhouse gasses in the atmosphere such as methane, carbon dioxide, water vapor, nitrous oxide, and ozone. “Global temperature has rose approximately 1.4 degrees Fahrenheit over
There are both natural and human-generated causes for global warming. Natural causes are much less than human causes. Natural causes have changed the climate by changes in sunlight and volcanic activity has shown an increase in gases in the atmosphere. Humans cause global warming by burning fossil fuels. This is an everyday activity and it is harming the Earth’s atmosphere. Like I explained earlier, carbon dioxide in the Earth has increased dramatically and this is cause by burning fossil fuels which results in the Greenhouse Effect. Almost everything in the world consists of fossil fuels in some type of way. We burn fossil fuels when driving our car, powering machinery, using electricity, flying planes, etc. (Planet Save) I thought that the following chart was very interesting because it explains that the human causes of global warming are extremely higher than natural effects.
The earth’s climate is predicted to change because human activities are altering the chemical composition of the atmosphere through the buildup of greenhouse gases –– primarily carbon dioxide, methane, and nitrous oxide. The heat-trapping property of these gases is undisputed. Although uncertainty exists about exactly how earth’’s climate responds to these gases, global temperatures are rising. Go to the Emissions section for much more on greenhouse gases.
In talking about global warming, we need to learn what causes the greenhouse effect. Rays from the sun are taken up and absorbed by water vapor that is natural in the atmosphere. The United States emits the largest man made greenhouse gases in the world. As Americans we must realize the responsibility to reduce the emissions. (Gore, Albert) Water Vapor is eighty percent of greenhouse warming. The last twenty percent results from other gases that are in very little amounts. A huge absorber of the sun’s heat rays is carbon dioxide. Us as humans release a lot of carbon dioxide. When fossil fuels are burned, they release big amounts of carbon dioxide. Carbon dioxide is on the increase in our atmosphere due to car emissions. Approximately eighty percent of CO2 increases because of man’s use of fossil fuels. When there is more carbon dioxide in our atmosphere the more sun rays are absorbed. In result to this happening this will cause the earth and the earths atmosphere to warm. When the earth is warming, water temperatures will start to get warmer. Oceans and lakes will get warmer in result f...
It is clear from looking at the atmosphere that human activity has a huge impact on the composition of the atmosphere in particularly the amount of greenhouse gases present and the effect these will have on the environment around us, consequently through global warming, resulting in climate change. Despite Climate change being a topical issue surrounded by great contention as it is based around scientific prediction it should not be ignored and the human activities which will lead to global warming should be challenged.
The evidence clearly provided in this essay strongly supports the argument that greenhouse gases caused by air pollution are the main cause of anthropogenic climate change. The tables and graphs demonstrate just how greenhouse gases contribute to climate change. As is evident, climate change is an ever growing problem globally. Due to the increase in anthropogenic air pollution, greenhouse gases have amplified also, as shown by table 2. Figure one shows how carbon dioxide in the atmosphere has increased exponentially, mirrored by anthropogenic emissions of carbon dioxide. The various examples described clearly support the argument that greenhouse gases caused by air pollution are the major anthropogenic causes of climate change.
As matter of fact, the increasing of greenhouse gases (GHGs) including water vapor (H2O), carbon dioxide (C...
As we approach the future we are faced with many global problems. Most of these problems arise because we have caused them ourselves. We need to face these problems and find a solution. Global warming, although most often overlooked in importance, is a crucial problem of the future directly related to human activities. Global warming is caused by gases humans release into the atmosphere called anthropogenic gases and by deforestation. Anthropogenic gases include carbon dioxide, methane, chlorofluorocarbons (CFCs), hydrofl...
As was previously stated, soil erosion is a main contributor to the deterioration of forests caused by deforestation and illegal logging. The r...
