M.Sc chemistry. Causes of Global warming :-Global warming is caused due to the Greenhouse effect. In the last few decades, a huge level of change in the climate and weather has been seen clearly. He began writing online in 2010, offering information in scientific, cultural and practical topics. To put this in perspective, the carbon we put in the atmospher… 184 "Sea level fell in 2010" Climate change includes both the global warming driven by human emissions of greenhouse gases, and the resulting large-scale shifts in weather patterns.Though there have been previous periods of climatic change, since the mid-20th century, humans have had unprecedented impact on Earth's climate system and caused change on a global scale.. The last decade, 2000 to 2010, was the hottest on record. Modern technologies has begun to curb the effects of global warming. Burning fossil fuels. These processes also release other greenhouse gases, such as methane and CFCs, although the concentration of CFCs has declined since their use was banned in 1988. Global warming is an aspect of climate change, referring to the long-term rise of the planet's temperatures. The main causes of global warming are, burning coal and other fossil. The pollutants that contribute to global warming are commonly known as greenhouse gas emissions. Firstly due to various natural causes and secondly due to man-made causes. However, the amount of all these greenhouse gases in the atmosphere can increase for two reasons. M.Sc chemistry. The facts about global warming are often debated in politics and the media, but, unfortunately, even if we disagree about the causes, global warming effects are real, global, and measurable. Global warming means an increase in the average temperature of the earth surface. Scientific American: Deforestation and Its Extreme Effect on Global Warming. These fossil fuels are mineral oil, coal, wood, etc. However, the light rays that are reflected from the earth’s surface and go back into space are basically infrared rays. In the trap of greenhouse gases, heat energy spreads from the earth to space.This heat is absorbed and emitted by these gases in the atmosphere in the form of infrared radiation. The United States Environmental Protection Agency explains the greenhouse effect as the rise of temperature the Earth experiences as greenhouse gases trap energy from the sun. The energy that then radiates out from the surface, longwave radiation, is trapped by the same greenhouse gases, warming the air, oceans, and land. Methane, another important greenhouse gas, comes from many natural sources, but also from the digestive systems of livestock raised for meat production as well as the decomposition of waste in landfills and the burning of biomass. 1. The pollution that causes global warming is linked to acid rain. According to Scientific American, deforestation is responsible for 15 percent of the greenhouse gases in the atmosphere. Results of Global Warming
Global warming is affecting many parts of the world, including melting glaciers, creating the sea to rise even more, and when that happens, the water covers many low land islands. Humans produce them by burning fossil fuels and engaging in various agricultural and industrial activities. The remaining 66% is exploited by the earth.23% of this 66% light energy is used to evaporate water and to evaporate water vapor for the water cycle. The causes of environmental degradation cannot be addressed by a patchwork of uncoordinated responses. This includes mountain glaciers, ice sheets … This reflected part is absorbed by various gaseous elements in the atmosphere as it returns to space. Warmer temperatures also result in the expansion of the water's mass, which causes sea levels to rise, threatening low-lying islands and coastal cities. No one doubts it is happening. Now more than ever it seems we can’t live without plastic. Consequently a huge extent of CO2 reduces in the atmosphere. CO2 (carbon dioxide) is one of the seven greenhouse gases in our atmosphere and accounts for 84 percent of greenhouse gases produced by human activity. The report also states with 95% certainty that the activity of humans has been the primary cause of increasing temperatures over the previous few decades, up from 90% in a previous report. The Guardian: Which Industries and Activities Emit the Most Carbon? Methane is also emitted from oil fields. Among the greenhouse gases, the increase of carbon dioxide in the atmosphere is the main cause of global warming, as predicted by Svante Arrhenius a hundred years ago, confirming the work of Joseph Fourier more than 200 years ago. Not all of these light rays are reflected by the earth’s surface and go into space. 1) A) climate 2) humidity 3) none 4) c) sea ice 5) d) dicidious forest 6)c) atmosphere 7) The natural greenhouse effect maintains the temperature of the Earth at a level to which we and other lifeforms have adapted, although it changes naturally the changes are very slow and allow time for adaptation and evolution. Among all of greenhouse gases, particularly carbon dioxide, water vapor, CFC and CH4 are capable of absorbing infrared rays. Climate change is global warming. • More frequent and intense extreme weather events: Extreme weather events like bushfires, cyclones, droughts and floods are becoming more frequent and more intense as a result of global warming. This phenomenon is called global warming. Next up, manmade causes are deforestation, mining, cattle rearing, fossil fuel burning and more. The second largest source of CO2 is the transportation sector, which generates about 1.7 billion tons of CO2 emissions annually. Combustion of fossil fuels is the main source of carbon dioxide. The world's leading climate scientists think human activities are almost certainly the main cause of the warming observed since the middle of the 20 th century. It also creates more clouds, rainstorms and other symptoms of climate change. Global warming is a deadly threat precisely because it fails to trip the brain's alarm, leaving us soundly asleep in a burning bed. The natural one includes a greenhouse gas, volcanic eruption, methane gas and more. Arctic sea ice extent is diminishing. The use of fossil fuels increased after the beginning of the industrial revolution. This carbon and methane pollution process traps more of the sun’s solar energy in the form of heat inside our atmosphere. The water absorbs the sun's heat, and the oceans also become warmer as a result. The “thicker” absorption layer keeps the earth warmer. Earth’s climate has changed over various timescales since the dawn of geologic time, and the force of human activities since the Industrial Revolution has been woven into the fabric of … Above all, alternative … The main causes of global warming are, burning coal and other fossil. 1. Global warming is a multi-faceted phenomenon that will have severe consequences if current trends continue. Since the Industrial Revolution, humans have been burning fossil fuels such as coal and petroleum for energy, which releases carbon dioxide into the atmosphere. Coal burning power plants are by far the biggest polluters. In addition, one of the global warming causes might be astronomical. Increasing livestock farming. Anthropogenic Causes of Global Warming. Each of the past three decades has been warmer than any preceding decade since records began in 1850. A.1 There are various causes of global warming both natural and manmade. 1. This is because among all of greenhouse gases especially carbon dioxide, water vapor, CFC and CH4 are capable of absorbing infrared rays. The source of CFC in the atmosphere is CFC that used as refrigerants in refrigerators, in air conditioners and in the preparation of perfume sprays, foams etc. What Causes Pollution That Leads to Global Warming?. When people burn fossil fuels like coal, oil and natural gas this adds carbon dioxide into the air. Although scientists argue about how quickly global warming is affecting the Earth, they do agree that burning fossil fuels like oil and coal causes greenhouse gases. Rainforest Action Network: How Many Trees Are Cut Down Every Year? The basic point is visible that light rays from the sun are incident on the earth’s surface. 42% of this light energy is absorbed by the atmosphere, land and sea. Carbon dioxide contributes 55% to global warming. The phenomenon of global warming has been occurring naturally as a result of the natural rotation of the sun which changes the intensity of solar radiation hitting the earth, also natural processes such as volcanoes produce a large amount of Sulphur dioxide and other greenhouse gasses which can result in global warming too. This creates a feedback loop that accelerates global warming. Sunlight produces a lot of water vapor from water bodies and the surface. This problem is an increase in the earth's temperature due to fossil fuels, industries, agricultural, and man-made causes. Its wavelength is 7750 nm. Earth's climate is the result of a balance between the amount of incoming energy from the sun and energy being radiated out into space.Incoming solar radiation strikes Earth's atmosphere in the form of visible light, plus ultraviolet and infrared radiation (which are invisible to the human eye), according to NASA's Earth Observatory.Ultraviolet (UV) radiation has a higher energy level than visible light, and infrared (IR) radiation has a lower energy level. TThe current global average temperature is 0.85ºC higher than it was in the late 19th century. Q.1 List the causes of Global Warming. The future predictions of global warming are important to note also. Global warming could reach a 'tipping point' In an interview with the BBC last July, Hawking warned that global warming could reach a point where it can't be reversed. It is directly linked to the increase of greenhouse gases in our atmosphere, worsening the greenhouse effect. The Earth itself also contributes with natural processes that create greenhouse gases and accelerate the warming trend. The future impact of global warming depends on the extent to which nations implement prevention efforts and reduce greenhouse gas emissions. Global warming refers to the long-term rise in the average temperature of the Earth's climate system.It is a major aspect of climate change, and has been demonstrated by the instrumental temperature record which shows global warming of around 1 °C since the pre-industrial period, although the bulk of this (0.9 °C) has occurred since 1970.
Global Warming also destroys many huge forests. That's what's known as the greenhouse effect. As a result, the traffic was completely stopped. As a result, the amount of greenhouse gases in the atmosphere can also increase. As global temperatures rise, global warming is an increasing concern. Although carbon dioxide receives the most press as the culprit responsible for global warming, water vapor is actually the most abundant greenhouse gas in the atmosphere. The increased demand for meat and dairy cattle has lead to the creation of feed lots in otherwise forested areas. A quarter of this is for heat and electricity, while another quarter is for other industrial processes and transportation, which includes gasoline- or diesel-powered cars, trucks, trains and airplanes. With the start of industry in the 1700's, humans began emitting more fossil fuels from coal, oil, and … The average energy coming from the sun generally has remained constant since 1750, and the warming does not occur uniformly throughout the atmosphere.
