What is Global Warming?

Global Warming is defined as the increase of the average temperature on Earth. As the Earth is getting hotter, disasters like hurricanes, droughts and floods are getting more frequent
The average facade temperature of the globe has augmented more than 1 degree Fahrenheit since 1900 and the speed of warming has been almost three folds the century long average since 1970.
This increase in earth’s average temperature is called Global warming. More or less all specialists studying the climate record of the earth have the same opinion now that human actions, mainly the discharge of green house gases from smokestacks, vehicles, and burning forests, are perhaps the leading power driving the fashion.

The gases append to the planet's normal greenhouse effect, permitting sunlight in, but stopping some of the ensuing heat from radiating back to space. Based on the study on past climate shifts, notes of current situations, and computer simulations, many climate scientists say that lacking of big curbs in greenhouse gas discharges, the 21st century might see temperatures rise of about 3 to 8 degrees, climate patterns piercingly shift, ice sheets contract and seas rise several feet. With the probable exemption of one more world war, a huge asteroid, or a fatal plague, global warming may be the only most danger to our planet earth.
Global Warming Causes
As said, the major cause of global warming is the emission of green house gases like carbon dioxide, methane, nitrous oxide etc into the atmosphere. The major source of carbon dioxide is the power plants. These power plants emit large amounts of carbon dioxide produced from burning of fossil fuels for the purpose of electricity generation. About twenty percent of carbon dioxide emitted in the atmosphere comes from burning of gasoline in the engines of the vehicles. This is true for most of the developed countries. Buildings, both commercial and

    Glaciers are melting, sea levels are rising, forests are drying and wildlife is suffering, these are all results of the apparent rise in global temperatures and it has become more obvious that humans over centuries are releasing harmful heat-trapping gases into the atmosphere known as greenhouse gases. The greenhouse effect causes the increase in global temperature as the gases which are released into the atmosphere allow light to be entered, but prevents heat from escaping.…

    Global warming is the gradual increase in the temperature of the earth's atmosphere and oceans, mostly caused by the greenhouse effect. The greenhouse effect is where incoming short-wave solar radiation from the sun can pass through the earth’s atmosphere to reach the surface; some of this radiation is then reflected back into space at a longer wavelength. Greenhouse gases in the atmosphere absorb some of this long wave radiation and re-radiate it back to the earth’s surface, trapping heat in our atmosphere. There have always been natural fluctuations in the earth’s temperature, for the last 2.5 million years earth has shifted between cold glacial periods, and warmer interglacial periods. We are currently in an interglacial period, where the temperatures have been warm, with very small fluctuations for the last 10,000 years. Over the last century global temperatures have increased rapidly, there was a sharp rise in temperature between 1900 and 2000 of 0.7oC. Most scientists agree that this sharp increase was caused by human activities (anthropogenic). This continued increase in temperatures could have many major impacts worldwide, both positively and negatively.…

    Global warming refers to an increase in global temperatures that happens at a gradual scale and has been attributed to the greenhouse gasses produced by industries through the release of chlorofluorocarbons, carbon dioxide and many other air pollutants (Haldar). The gasses trap heat energy from the sun causing the gradual increase in temperatures. Global warming has had negative impacts on many ecosystems around the world among them droughts, unpredictable weather patterns, sea level rises and retreating of the major ice sheets due to melting. Global warming has had an effect even on the arctic tundra. Most researchers agree that human activity is the most responsible for causing global warming.…

    Global warming is the rising of the temperature on the Earth’s surface and atmosphere. There are many causes that help increase Global Warming and greenhouse gases is an important factor. Greenhouse gases such as carbon dioxide are very harmful to the environment as well as to humans.. The Industrial Revolution in the 19th is a major cause of global warming. It has resulted in the increase of the nitrous oxide and carbon dioxide (Greenhouse Gases) in our atmosphere, resulting our Earth to heat up causing the ice caps to melt, rising the sea levels, increased coastal, unusual weather patterns and ocean currents, and consequent threats to the survival of some living things.…

    One cause contributing to the increased average of global temperatures is the increase of carbon dioxide and other “greenhouse” gases in our atmosphere. The greenhouse effect causes an increase in the Earth’s temperature from atmospheric gases, including carbon dioxide, methane and nitrous oxide, disrupts the cycle of energy by trapping the outgoing energy from the Earth, which is supposed to be on its way back to space (Shah, 2012). Instead, the energy is retained on Earth; causing natural temperature to increase as well as polluting the air. Human activity has contributed to this natural effect through the excessive burning of fossil fuels since these fuels rapidly release carbon dioxide into our atmosphere while not removing the gas, which leaves high levels of CO2…

    It's nearly impossible to overstate the threat of climate change. Greenhouse gas emissions are rising more rapidly than predicted and consequently the world is warming more quickly. Global warming will have catastrophic effects such as accelerating sea level rise, droughts, floods, storms and heat waves. These will impact some of the world's poorest and most vulnerable people, disrupting food production, and threatening vitally important species, habitats and ecosystems.…

    What is global warming? It is the increase in the mean temperature of the Earth’s atmosphere. It is said that the temperature has been rising by 0.5° every year and the highest temperature recorded was 47.6° in Faya, Chad in 22nd June 2010. This causes the sea levels to rise due to the snow melting. It is said that the sea levels will rise by at least 25 meters by the year 2100. The sea surface temperature has risen in the last few years. This means there will be more evaporation taking place and this frees several chemicals which help global warming take place.…

    Global warming begins when sunlight reaches Earth. The clouds, atmospheric particles, reflective ground surfaces and ocean surface then reflected about 30 percent of it back into space, while the remaining is absorbed by oceans, lands and air. This in turn heats the planet’s surface and atmosphere, making life possible. As Earth warmed up, this solar energy is radiated by thermal radiation or infrared heat, traveling directly out to space, thus cooling the Earth. However, some of the outgoing radiation is re-absorbed by carbon dioxide, water vapor and other gases in the atmosphere and is radiated back to Earth’s surface; these gases are known as greenhouse gases due to their heat-trapping capacity. This re-absorption process is naturally good; the Earth’s average surface temperature would be very cold if not for the greenhouse gases.…

    Every year, almost 7 billion tons of carbon dioxide is released into the atmosphere by human activity (“How do we contribute individually to global warming.” Global Warming: 2006. Web.12 Oct. 2011). That is the equivalent of 107,700,000 jet airplanes being in the air at once! This harrowing figure is the main cause of global warming, and has been increasing for the last 50 years. Global warming is caused by the increase of greenhouse gases, carbon dioxide and methane primarily, in the earth 's upper atmosphere directly caused by human burning of fossil fuels, industrial, farming, and deforestation activities. Global warming is defined as an increase in the average temperature of the earth 's atmosphere (especially a sustained increase that causes climatic changes). Many people believe in these statements, but there are many people around the world that refuse to believe that human contributions are the main cause of global warming, saying that the increase is part of the natural climatic change of earth.…

    There is little debate that the earth is undoubtedly warming. It has been the subject of intense debate for decades now. Greenhouse gases such as carbon dioxide and industrial gases from fossil fuels play a huge role in why our environment is changing so rapidly. With projections of an increase between 2.5 and 10.5 degrees by the year 2100, it is really nothing to take lightly. According to some scientific studies, the main gas causing global warming, CO2, or carbon dioxide, has increased in our atmosphere by as much as 30 percent over the last 100 years. That is a significant increase to say the least.…
