The most abundant greenhouse gas, but importantly, it acts as a feedback to the climate. Water vapour increases as the earth’s atmosphere warms , but so does the possibility of clouds and precipitation , making these some of the most important feedback mechanisms to the greenhouse effect. Carbon dioxide. A minor but very important component of the atmosphere , carbon dioxide is released through natural processes such as respiration and volcano eruptions and through human activities such as deforestation, land use changes, and burning of fossil fuels. Humans have increased atmospheric carbon dioxide concentration since the industrial revolution began.
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
Burning these fossils releases carbon dioxide and many other gasses that are directly causing the global warming because these greenhouse gasses increase the temperature of the earth and eventually affect the environment change. Reports and studies notify that during the past 100 years Earth’s surface temperature has spiked up to 0.6 Celsius, and while this might not seem to be a big number but even one-degree increase, can affect the Earth’s surface
Global warming and climate change is not region-specific. It spreads all over the world. Climate change occurs when atmospheric temperature increases a lot which in turn causes many different changes to earth. According to Camelia & Răzvan (n.d), the scientists in different fields consider climate changes as a global challenge which can get irreversible results. Since the revolution of the industry, human activities was increasing day by day, during this period, cultivated land, natural resources, forest resources and various raw material is breaking up by human, so as result of that, a lot of greenhouse gases was released and this lead to global warming (Huang & Li, 2015).
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
Ian Hall ENGL 150, 10 am January 29, 2018 Informative Essay Global Warming Informative Essay So what exactly is global warming? Global warming also referred to as climate change is the gradual increase in the overall temperature of the earth 's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants in the air today. There are two causes of global warming, human influences and also natural causes. Global warming is increasing day by day because of all the natural causes going on. A greenhouse is a glass building that contains plants in it that needed to be protected from cold weather.
The global average temperature increased by about 0.8°C from 2005, but the current warming trend is 0.13 – 0.16 °C per decade, and it is projected to continue to rise at a rapid rate (Hansen et al.2010). The effect of the activities of man especially in technologically advanced nations, has brought about emission of CO2 and other greenhouse gases which has resulted in the depletion of the ozone layer and global warming (Hegerl et al., 1997; Tett et al., 1999, 2002; Stott et al., 2000).These can be seen from the changes in meteorological parameters such as temperature and precipitation. The Intergovernmental Panel on Climate Change (IPCC) likewise agreed to this, that the varying greenhouse gas concentrations were more to be the major cause of climate change (Climate Change 2001: The Scientific Basis—Contribution of Working Group I to the Third Assessment Report of IPCC, 2001). However, climate change pose as a great threat to biodiversity, the ecosystems, economic growth, global food security, life as a whole and encourages inequality (Kurnik, 2015 - for IPCC). In view of this effect of climate change, it is of necessity to project and observe
Humans Affect Global Warming Global warming is an increase in the Earth's average atmospheric temperature that causes the corresponding change in climate and may result from the Greenhouse effect ( “Global Warming”,n.d.). Global warming increase 37% in 2016 to 45% in 2017 (“Scientists Agree: Global Warming is Happening and Humans are the Primary Cause”, n.d.). The increase in global warming is all surrounded by humans and their worldly activities. Human Activities Cause Global Warming Humans everyday life activities cause the rise in global warming. Earth has been shaping, changing, and warming for many years, but the increase in modern and advance life on Earth is doubling the cause of global warming.
Throughout the course of history the earth’s climate has dramatically, changed within the last 650,000 years, there has been seven cycles of glacial advance and retreat. “In the past two decades, the scientific community has reached an overwhelming consensus those human activities are causing changes to the global climate.” (David B. Resnik). There has been a massive increase production of carbon dioxide, methane, and other greenhouse gases in the last century that has caused the climate change around the world. “If humanity does not start significantly reducing greenhouse gas emissions, average global temperatures will likely increase by several degrees Celsius in the next fifty years, which would lead disastrous environmental consequences, such as flooding of coastal areas, increased numbers of powerful hurricanes, desertification, decreased agricultural productivity, and loss of biodiversity.” (David B. Resnik). The main driver of today’s warming is the combustion of fossil fuels.
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.
