GLOBAL WARMING
This term is used to describe the increase in the earth’s temperature. According to the Intergovermental Panel of Climate Change (IPCC) around 95% of the global warming is caused due to greenhouse gases. Greenhouse gases are very harmful for the environment as they absorb and emit infrared radiations that the sun projects on the earth. This effect of greenhouse gases trapping the ultraviolet rays is called the greenhouse effect. There exist a number of causes, the major ones being the burning of fossil fuels, deforestation, population growth and industrialization. Global warming causes various events around the world like rise in sea-level, ocean acidification, and extreme weather events like hurricanes, cyclones and tsunamis. “Food insecurity, migration, water stress and economic recession are some of the impacts associated with climate change. Termed as a “threat multiplier,” climate change is increasingly being recognized as a trigger of violent conflict around the world.” [Khan Lone, A. (2015)] . There is an unquestionable amount of social conflict as well which arose due to global warming.
DEFORESTATION
The Lorax (Dr. Seuss) states its main message as “don’t cut trees”, deforestation is a major form of land degradation. Deforestation is an activity taking place in all parts of the world, especially developing countries. The requirement of land and timber for agricultural and industrial purposes has drawn many to cut down not just a few trees but vast
Global warming -- and climate change -- have long-term and short-term impacts on our environment. Caused by air pollutants such as carbon dioxide and methane, global warming is the gradual increase of air temperature across the globe. The rise in air temperatures can lead to higher extinction rates, increased risk of disease and political repercussions, such as wars over available resources. Understanding the possible short-term and long-term effects can help humans better prepare for the consequences of global warming.
Climate change or global warming is the effect of greenhouse gas emissions, entering the atmosphere. Essentially the Sun’s rays enter the atmosphere and then are ‘blocked’ by these gases and prevented from leaving. The stored sun rays heat up the Earth, meaning rising sea levels because of the heated climate. Society is majorly impacted by the fatal issue and there are many views and opinions of what climate change is and what it will cause.
Global warming is an increase in the temperature of the earth's weather. Global warming is also known as the green house effect. Global warming is a very serious world issue. Most humans are trying to do as much as they can to help stop global warming. Global warming has caused many problems to the earth in addition to the humans that live here on the earth. A problem caused by global warming is very hot summers. Some summers have had days that the temperature had reached 30*C. Another Problem that global warming has caused is the melting of polar ice caps. Global warming caused the polar ice caps to melt which will cause the ice to break free as well as melt in the sea, sea levels all over the world will rise. Lastly,
Global warming (the greenhouse effect) is the increase in the temperature of Earth's weather which has become popular to many people as one of the most important danger in the universe. Discussions about causes, solutions, postive and negative effects have made by human-beings.
Climate Change “refers to changes in the Earth’s climate caused by increasing concentrations of carbon dioxide and other pollutants produced by human activity.” Global warming is the increase of the average surface temperature on Earth caused by the excess release of greenhouse gases, such as carbon dioxide, into the atmosphere. Greenhouse gases occur naturally, but in excess it could be harmful to the Earth. Composition of greenhouse gases traps heat from the sun, and this is what helps the Earth stay warm enough to sustain life. The more heat they trap, the warmer the earth gets, and as the planet gets warmer it creates climate changes. The greenhouse gases that are making the earth warmer are generated by human activity. One of the main greenhouse gases is carbon dioxide, which is being mostly released by the burning of fossil fuels. Other gases are Methane, which is released through industrial and agricultural processes and Nitrogen Dioxide which is a product of some industrial processes.
Global warming is a phenomenon that shows an average of the increase in temperature of the Earth's atmosphere and oceans. In the last decades, this phenomenon has caused a lot of damage in several places in the world, those being reflected as floods, fires, and change in the temperature around the world. Therefore it is important to raise awareness to reduce the damage caused, which is mainly due to industrialization and a large number of factories that are around the world, and made by the human hand. Global warming is an increase in the average temperature of the atmosphere over time, which has risen mainly by carbon dioxide emissions, which takes part in the increase of the greenhouse effect. It is a natural phenomenon caused by a series of gases that are in the atmosphere, causing some of the heat of the sun to be trapped in the atmosphere, giving cause to high temperatures to occur.
Every place becomes warmer because people always do the things that would damage the planet. For example the people usually use the air conditioner, this would discharge a lot of greenhouse air. That is too late to save it from complete destruction when climate change has damaged the planet beyond repair. Global warming is caused by the factory and cars always discharge CO2. ’ Global warming is primarily a problem of too much carbon dioxide (CO2) in the atmosphere—which acts as a blanket, trapping heat and warming the planet.’ (Union of Concerned Scientists, 2011) Some people think that it is not a serious problem to damage the planet or they can still save the planet. However, Global warming has already caused serious destruction to the planet and it is too late to save it because the planet start to arise many problems and people cannot do anything to help the planet.
A few factors cause global warming. First,the main factors of global warming is human population explain, which also threatens the balance between man and nature. Second, People cut down trees to make more than a certain carbon dioxide content of the Earth such as wearing a jacket, it will produce the greenhouse effect , the Earth will warm , the iceberg will melt , sea levels will rise, the weather will be an exception. Global warming refers to the increase in global temperatures . Nearly 100 years, the average global temperature has experienced cold - warm - cold - warm twice fluctuations gotta look for the upward trend. After entering the eighties , global temperatures increased significantly. From 1981 to 1990 the average global temperature increase of more than 100 years ago, 0.48 ℃. The main reason for global warming is human in nearly a century extensive use of fossil fuels such as coal , oil , etc. , a large amount of CO2 emissions and other greenhouse gases (NOAA National Climatic Data Center). Since these greenhouse gases on shortwave radiation from the sun with a high degree of permeability , while the long-wave radiation reflected from the Earth is highly absorbent , it is often said that the greenhouse effect " , leading to global warming. Global warming consequences , causes of global redistribution of precipitation , melting glaciers and permafrost , rising sea levels , not only endanger the balance of natural ecosystems , but also threaten the human food
When we think of global warming, we think about Air pollution, rise of temperature, melting glaciers, carbon dioxide emissions and so no. But even though we know that these factors could lead to a global catastrophe, very often we do not realize what king of severe effect the global warming could have on our planet.
It is no secret that the magnificent glaciers that cover this earth are facing negative repercussions due to climate change. Pratima Pandey verifies this statement in her article by stating that “it is the climate that is the driving force controlling the mass balance of a glacier in space and time, resulting in the recession and advancement of a glacier,” (Pandey, par. 1). The earth is getting warmer, and this means that soon, glaciers will start to disappear. While the earth naturally produces its own heat, the contribution from humans is also making the earth warmer than usual. James Balog and Extreme Ice Survey team explain that “since the Industrial Revolution, burning of fossil fuels has ratcheted up the burning of greenhouse gases, like carbon dioxide, which traps heat in the atmosphere (Global Warming). Greenhouse gases then go to raise the already increasing temperatures, which are causing glaciers to melt. This is a sad reality for the glaciers of the earth. The melting of glaciers can cause ocean and sea levels to rise, which in turn can flood different animal habitats and displace millions of people. Also, the melting can lead to the loss of freshwater sources to those who use reservoirs as a source of drinking water, such as those around Asia near the Himalayan glaciers. Lastly, if the climate continues to melt the glaciers, various different tourist attractions, such as Glacier National Park will no longer draw in visitors to view the magnificent beauty.
“All across the world, in every kind of environment and region known to man, increasingly dangerous weather patterns and devastating storms are abruptly putting an end to the long-running debate over whether or not climate change is real. Not only is it real, it's here, and its effects are giving rise to a frighteningly new global phenomenon: the man-made natural disaster” (Barack Obama, April 3, 2006). What could be causing these extreme weather patterns? Scientists say that it is the gradual increase of the temperature over the entire earth. Global warming is the increase in the average temperature all over the earth. Global Warming is a major problem in the world today and is argued among all of the world leaders. I am going to talk
Climate change is a long-term alteration in the statistical distribution of weather pattern over periods ranging from decades to millions of years. The world is currently experiencing drastic change in temperature. This change can be felt in the tropical climate areas where the weather is getting hotter and hotter every day. The change in global temperatures and precipitation over time is due to natural variability or to human activity. It is also caused by accumulation of greenhouse effects (Arrhenius, 1896). Should we as humans let this problem worsen? Climate change will affect everything including humans, flora and fauna, and the environment.
As Albert Einstein said “Look deep into nature and then you will understand everything better”. It can be hard, but not impossible to understand more about this ever changing universe. Without a doubt, our planet as we know was not the same a century ago and it will not be the same a decade from now. Due to this perpetual evolution of our planet’s natural cycles, its inhabitants are forced to choose between adaption or extinction. Meanwhile, an invasive species, or humans, has started a chain of disasters that are accelerating global changes and, in extension, the crucial selection of existence. Over the years, the field of natural science has increased human knowledge regarding our negative impact on the planet. Despite this, humans have taken minimal action towards addressing the problem that, considered a myth by some, is global warming. Many of us take our planet for granted, not realizing that, in of its own, it consist of one huge ecosystem relying on all of its parts to function properly. Because of this interdependence, action must be taken to minimize and raise awareness of global warming on the arctic region and its resulting effects on ecosystems around the world.
Uncertain earth climate brings about unpredictable natural hazards; therefore it is necessary to acknowledge if the earth is getting warmer or cooler, what truly causes these changes, and is there a casual relationship between the increase of carbon dioxide and global warming. Only when these study results are reasonable and accurate, relevant forecast and clear polices can be made and implemented. In other words, those biased studies results might point out an opposite direction to protect earth environment and even make current situation get worse. For example, the original aim of Earth Hour is to reduce carbon emissions and balance climate change; however, according to Luke Weston’s lab experiment (2008), the candle burned during Earth Hour, shows that greenhouse gas emissions are increased by 9.6 g of carbon dioxide over electric lighting. Therefore, some misguided results might bring about inappropriate propose and run in opposite directions.
The Effects of Global Warming The CO2 levels in the atmosphere are increasing faster and faster
