Scientists have done a lot of researches about this matter and recent ones showed that the greenhouse effect is increasing by the release of specific gases to the surrounding that make the earth’s temperature hotter causing global warming. Carbon dioxide supposes for around 85% of
The greenhouse effect is closely associated to global warming. It occurs because of how carbon molecules are shaped. They allow light to pass by them but they block reradiated infrared rays because these rays are longer than the light. That trapping is effectively how greenhouses function and is where the name comes from. And because of how much carbon gets released into the air this effect is amplified (Nye and Powell
One of the biggest issues facing us right now is global warming. “Scientists have discovered that the Earth 's average temperature has risen by 1.4 degrees Fahrenheit.”(Alina Bradford, “What is global warming?”) Global Warming refers to the rise of temperature on the Earth 's surface and atmosphere. This is due to the Enhanced greenhouse effect. “The Greenhouse effect is the process in which the earth receives sunlight rays from the sun and uses it to maintain its average surface temperature.” (“Short Summery for the greenhouse effect”) “Some of these rays are reflected back from the Earth 's surface and are trapped by the gases such as, carbon dioxide and methane etc, heating the Earth. When these gases are emitted from the Earth and traps more heat, it is called the Greenhouse Effect which leads to a rise in temperature.
The sun energy is continuously bombarded on earth. Some amount of energy is absorbed by ocean and control oceanic currents and weather but some energy by the process of photosynthesis enters into biological system (Rabinowitch, 1961; Whitaker and Likens, 1975). Due to industrialization, the release of greenhouse gases into atmosphere cause an increase in carbon dioxide concentration by 280 parts per million in 1750 and 390 ppm in 2010 (Kumar et al.2011). Mainly theindustries of plastics, paint, solvents, packaging and cleaning compounds utilizes the carbon. According to Mauna loa observatory in Hawaii, shows the seasonal and annual changes in carbon concentrations since 1958 by keeling curve.
Global warming is a gradual increase in the overall temperature of the earth 's atmosphere because of the greenhouse effect caused by the increasing levels of carbon dioxide and other carbon gases (normally by human activity). Even an increase in temperature of 1ºC in a century is considered global warming. The atmosphere heats up because of the enhanced greenhouse effect. This is a natural process that traps heat to keep the atmosphere warm, but humans have accelerated the process by adding carbon gases to the atmosphere. This process starts when UV rays from the sun hit the Earth and are reflected by the surface as infrared.
The dominant product of fossil fuel combustion is carbon dioxide, a greenhouse gas. The overall effect of human activities since the Industrial Revolution has been a warming effect, driven primarily by emissions of carbon dioxide and enhanced by emissions of other greenhouse gases. the points made are all causes of climate change. Many decisions to be made today have long-term consequences and are sensitive to climate conditions – water, energy, agriculture, fisheries and forests, and disasters risk management. We simply can’t afford to get it wrong.
As the more heat hold by greenhouse gasses, the temperate will rise, which cause climate change. First demonstrated of atmospheric carbon dioxide in warming the Earth's surface was Swedish scientist Svante Arrhenius over 100 years ago. Ever since scientific data have established at the time. Since then, scientists have recorded every change of temperature by analysis the atmospheric CO2. The record shows burning coals, oil and natural gas have emitted roughly 500 billion tons of CO2 that abort by the atmosphere since Industrial Revolution (NWF).
“The theory of human activity (fossil fuel burning) being a direct cause of global warming is based on the assumption that atmospheric carbon dioxide concentration is directly related to global warming. Is this assumption valid?” Global warming is brought about by the greenhouse effect. The greenhouse effect Gasses in the troposphere cause the greenhouse effect. There is a correlation between the temperature of the earth and the concentration of carbon dioxide in the troposphere, however, correlation does not infer causality. The earth receives energy from the sun in numerous wavelengths.
GLOBAL WARMING INTRODUCTION Global warming is defined as the growing of the average temperature on earth. As earth receiving hotter, disasters like hurricanes, droughts and floods are getting more frequent. Over the last 105 years, the average air temperature near the surface of the earth has increased by little less than 1 or 1.3 degrees Fahrenheit. Global warming is the cause and climate is the effect. It is very warm at the earth’s Poles, the Arctic and the Antarctic.
This research is about the medium changes or ’Global Warming’. Global means the universal and warming means warm up or heating, they two retreats To The observed century-scales rise in the level heat of the ground medium And its related effects, also global warming also returning to any genetic changes in medium. Evidence sees that the medium system is changing; most of the additional energies are stored. In the medium system from the 70s has gone into high ambient heat, the rest has Melted the ice and heating the bitumen and air, the water rise in world class level. Outside heat and aerial carbon dioxide have been more fast in last decades than the Normal changes of antecedent millennia and sphere are now higher than at Any time for millions
