The Effect of Greenhouse Gases on Earth’s Temperature (original) (raw)

Greenhouse Gas Emissions Increase Global Warming

This paper discusses the greenhouse gas emissions which cause the global warming in the atmosphere. In the 20 th century global climate change becomes more sever which is due to greenhouse gas emissions. According to International Energy Agency data, the USA and China are approximately tied and leading global emitters of greenhouse gas emissions. Together they emit approximately 40% of global CO 2 emissions, and about 35% of total greenhouse gases. The developed and developing industrialized countries together emit 90% of the global CO 2 equivalent gases. Due to global warming the ocean levels are increasing, as a result most of the costal areas will submerge by 2050, and some insects and animals will extinct. Hence immediate steps to be taken to reduce greenhouse gas emissions to safe the future generations. The paper emphasizes on the affects of global warming and different ways to reduce greenhouse gas emissions.

Greenhouse Effect: Greenhouse Gases and Their Impact on Global Warming

The Greenhouse effect is a leading factor in keeping the Earth warm because it keeps some of the planet's heat that would otherwise escape from the atmosphere out to space. The study report on the Greenhouse gases and their impact on Global warming. Without the greenhouse effect the Earth's average global temperature would be much colder and life on Earth as we know it would be impossible. Greenhouse gases include water vapor, CO 2 , methane, nitrous oxide (N 2 O) and other gases. Carbon dioxide (CO 2) and other greenhouse gases turn like a blanket, gripping Infra-Red radiation Mini-review Article

Examine the Effects of Greenhouse Gases on Climate Change

Greenhouse gases have an important role in understanding earth climate history. Based on these studies greenhouse effect which produces heat due to trapping of heat by greenhouse gases in adjusting earth temperature, Climate change refers to the oscillations in earth global or regional climate in time interval and defines those changes that fluctuate with mean atmospheric conditions or average weather (common) in timescale intervals which fluctuate between decades to million years. Researches and specialists believed that with using of pure energies like solar, windy and heat ground energy and etc, instead of energies cause by fossil fuels will impede of environmental protection implication. So the average volume of light shining at a day is 4 kilowatt H/m 2 and the average volume of sunny hour is more than 2800 hour at a year. These changes may have been resulted from earth internal processes or forces beyond it or in recent times due to activities related to the man-made climatically changes. Especially in recent application in the subject of environment policy, the expression of; climate change; often refers to the current changes in new climate.

The Effects of Global Warming new

Climate change is the most important issues that the world must facing today. It affected human and environment in all aspects. Climate change caused by green house effect. Greenhouse gases act like a blanket around Earth, trapping energy in the atmosphere and causing it to warm. This phenomenon is called the greenhouse effect and is natural and necessary to support life on Earth. However, the buildup of greenhouse gases can change Earth's climate and result in dangerous effects to human health and welfare and to ecosystems.

The Greenhouse Effect and Its Impacts on Environment

2015

The buildup of so-called “greenhouse gases” in the atmosphere CO2 in particular-appears to be having an adverse impact on the global climate. This paper briefly reviews current expectations with regard to physical and biological effects, their potential costs to society, and likely costs of abatement. For a “worst case” scenario it is impossible to assess, in economic terms, the full range of possible non-linear synergistic effects. In the “most favorable” (although not necessarily “likely”) case (of slow-paced climate change), however, it seems likely that the impacts are within the “affordable” range, at least in the industrialized countries of the world. In the “third world” the notion of affordability is of doubtful relevance, making the problem of quantitative evaluation almost impossible.

GLOBAL WARMING - CAUSES, IMPACTS AND REMEDIES

Global Warming is now becoming a challenge for survival of species on Earth and draws attention of many modern societies, power and energy engineers, academicians, researchers and stakeholders to go for deeper study. Almost all countries are required to act fast and attend to major problems of depletion of fossil fuel resources, poor energy efficiency and environmental pollution and its dire consequences on priority. This book is written to create awareness of the energy engineers, academicians, researchers, industry personnel and society as a whole, and to emphasize current status of global warming and its impact on climate changes. We all know that humanity is at risk due to Greenhouse gases which are the main source of Global Warming . Our beautiful planet is being destroyed, due to excessive exploitation of Earth’s resources from its reservoirs and other serious man-made problems. The main objective of this book is to produce a good documentation from the point of view of knowledge seekers or public readers at large, and also those who are eager to know more about Global Warming and its impact on the Climate Changes, besides those who have raisen their voice for its remedial measures. Present state of environmental damage and continuous occurrence of natural disasters have made the environmentalist and scientists inevitable for their extensive study, and to carry out detailed analysis of the following threats faced by civilization across the entire globe due to global warming: i). Is Global Warming caused by human activity? ii). What are Greenhouse Gases? iii). Fast shrinkage of polar ice may leave us with no ice by summer 2040. iv). Fast rise of the Sea Level. v). Danger for species like polar bear, etc. vi). Ice sheets, where they meet at the Atlantic sea. This area may be affected by cold waves, heavy snow falls and intense storms. vii). Permafrost may create further warming which cannot be reversed. The Global Warming is increasing Earth's average surface temperature, due to the effect of Greenhouse gases such as: Carbon dioxide through emissions produced from burning of fossil fuels or from deforestation, which traps heat that would otherwise escape the Earth. This is a type of Greenhouse effect . The most significant Greenhouse gas is actually Water Vapor , not something produced directly by humankind in significant amounts. However, even slight increase in atmospheric levels of Carbon dioxide (CO2) can cause a substantial increase in Earth’s atmospheric temperature. The ultimate effects, which we are likely to be faced as 21 st century.

IMPACTS OF GLOBAL WARMING ON ENVIRONMENT - A REVIEW

Earth’s environment is very sensitive and dynamic. Generation of greenhouse gases more than what the nature can bear results in global warming (climate change). A comprehensive review of impact of global warming on the environment is presented. It will be helpful for researchers and planners. Review stresses the urgency to check and control the greenhouse gases emission to save the biosphere in the earth planet.

Impact of Increase in Greenhouse Gases on Global Warming and Its Remedies

Journal of emerging technologies and innovative research, 2017

Sustainable energy is the golden thread that connects economic growth, social equity, and a climate and environment that enables the world to thrive. Deep reductions in emissions are possible without undermining the global economy through rapid and significant advancement and deployment in climate-friendly technologies such as renewable energy and emerging technologies such as carbon capture and storage. Such technologies will expand the options for reducing greenhouse gas emissions, and thus for international cooperation. Progress at the global level must be coupled by action on the ground. Steps should be taken to stabilize the concentrations of greenhouse gases in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system. Key-words: greenhouse gas, global warming, climate change, greenhouse effect, Ozone layer depletion.

The Greenhouse Effect & the Global Warming

Our planet Earth is facing a serious problem called Global Warming; the Earth's surface temperature is getting warmer and warmer, which is changing the Earth's climate everywhere with devastating affects on weather patterns across globe. It has a range of potential ecological, physical and health impacts, including extreme weather events (such as floods, droughts, storms, and heatwaves); melting of the ice caps causing sea-level rise; altered crop growth; and disrupted water systems and others. The climate change that we are witnessing is one of the greatest challenge facing humanity today. This may also put out many species at high risk of extinction, threatening the collapse of marine food chain and ecosystem. Shortage of food and water may trigger massive movements of people leading to migration, conflict and famine. Scientists generally agree that unless we address this problem now the situation will get worse and eventually will threaten the very life on earth. Scientist also generally agree that one major contributor to this global warming is the higher concentration of the greenhouse gas carbon dioxide CO2 in the atmosphere. This brings us to the important and interesting climatic phenomenon called the Greenhouse effect. Normally the Earth's atmosphere is very cold, so cold that normally life on Earth is not feasible. Today, it is possible for us to live on the Earth only because of what is called this Greenhouse effect where the so-called greenhouse gases. (GHG:water vapor, carbon dioxide, methane, nitrous oxide, and ozone.) in the atmosphere trap some of the Sun's radiation and radiate these back to the Earth. The process is called the Greenhouse effect, a term taken from the operation of the greenhouses. However, this is somewhat a misnomer; a greenhouse is not primarily warmed by the Greenhouse effect. Anyhow, our Earth is one of the few planets in our Solar system where this Greenhouse effect occurs. Other planets where this Greenhouse effect occur are Venus, Mars and Titan. Without this Greenhouse effect, the average temperature of the Earth's surface would have been very cold, about −18 °C (0 °F) rather than the present average of 15 °C (59 °F) which is comfortable for human life. This present average of 15 °C (59 °F) may be called the normal temperature of the Earth for human civilization. The Greenhouse effect works by preventing absorbed heat from leaving the earth through radiative transfer. Normally, the Earth receives energy from the Sun in the form of ultraviolet, visible, and near-infrared radiation. About 26% of the incoming solar energy is reflected back to space by the atmosphere while about 19% is absorbed by the atmosphere. Most of the remaining 55% energy is absorbed by the surface of the Earth and some are radiated back. Because the Earth's surface is colder than the Sun, it radiates back infrared light at wavelengths that are much longer than the wavelengths that were received. The atmosphere in turn radiates back some of this energy downwards depending on the strength of the greenhouse gases. This leads to a higher equilibrium temperature of the Earth surface than if the atmosphere were absent. The strength of the Greenhouse effect-how much extra energy it directs toward the Earth's surface-depends on how many greenhouse gas (GHG) molecules there are in the atmosphere. When GHG concentrations are high, they absorb a greater percentage of the Earth's infrared energy emissions. This means that more energy gets reemitted back toward the Earth's surface, raising its average surface temperature. We can think of the atmosphere as a heat-trapping grid surrounding the Earth. Water vapor, Carbon dioxide and other GHG are the solid bars of the grid while non-greenhouse1 gases (nitrogen and oxygen) are the open spaces between the grid bars. When infrared energy hits an open space of the grid, it escapes into outer space and dissipates; but when it hits a solid bar, the bar heats up and reradiates some portion of the energy back toward the Earth, raising its overall temperature. The more GHG molecules there are in the atmosphere, the more wide are the bars of the grid, shrinking the open spaces and making it harder for infrared energy to escape into space. The tighter the grid, the more energy it absorbs, and the hotter the Earth gets. We need to note that CO2 is not the biggest contributor of the GHG. Water vapor in the form of clouds is the greatest contributor with (32-76%). of these GHG. However, while we humans don't have any control on the natural process of formation of the water vapors (clouds) which are formed based of the surface temperature of the oceans, we humans have control in formation of the next biggest contributor of the GHG, the CO2 which contribute as much as (9-26%) of the GHG. Carbon dioxides also essential for life-animals exhale it, plants absorb and sequester it. There is a natural carbon cycle in the Earth's atmosphere. Carbon is absorbed from the atmosphere when photosynthesizing organisms such as plants, algae, and some kinds of bacteria pull it out of the air and combine it with water to form carbohydrates. It is returned to the atmosphere as CO2 when humans and other animals breathe it out, or when plants die and decompose. For the past thousands of years, this balance of intake and emission has kept the amount of carbon dioxide CO2 in the atmosphere constant. But in modern times, by burning an ever-increasing amount of fossil fuels, we are putting our finger on the scale, tipping the balance toward more CO2 emission. When we mine fossil fuels and burn them for energy, we are
