Greenhouse effect, a warming of Earth's surface and troposphere (the lowest layer of the atmosphere) caused by the presence of water vapour, carbon dioxide, methane, and certain other gases in the air Of those gases, known as greenhouse gases, water vapour has the largest effect The origins of the term greenhouse effect are unclear French mathematician Joseph Fourier isThe greenhouse effect occurs when certain gases in the Earth's atmosphere (the air around the Earth) trap infrared radiationThis makes the planet become warmer, similar to the way it makes a greenhouse become warmer The greenhouse effect is caused by greenhouse gases;This effect is called globalwarming By burning fossil fuels, industrial societies like Western Europe and the Americas are putting carbon dioxide into the atmosphere at a faster rate than plants can absorb it This is adding to the greenhouse effect, hence an enhanced greenhouse effect occurs, and this may be causing global warming

Simple enhanced greenhouse effect diagram
Simple enhanced greenhouse effect diagram-The "Greenhouse Effect" A greenhouse is a building made of glass that allows sunlight to enter but traps heat inside, so the building stays warm even when it's cold outside Because gases in the Earth's atmosphere also let in light but trap heat, many people call this phenomenon the "greenhouse effect" The greenhouse effect worksAnthropogenic or human release of carbon dioxide is what is contributing to an additional or enhanced greenhouse effect Footnote
Enhanced greenhouse effect The concentration of carbon dioxide in the atmosphere has increased in the last 0 years The concentration of carbon dioxide in Greenhouse gases absorb energy, slowing or preventing the loss of heat to space These gases act like a blanket, making Earth warmer than it would otherwise be and throwing off the energy balance of the planet This is known as the greenhouse effectGlobal warming is attributed to the enhanced greenhouse effect This is caused by the increased concentration and effect of greenhouse gases, such as
A short video explaining the enhanced greenhouse effecthttps//wwwspendmoretimeinthewildcoukHere at Spend More Time InA diagram showing how the greenhouse effect works on Earth Although the greenhouse effect is a natural phenomenon, there are concerns with something known as the enhanced greenhouse effect The enhanced greenhouse effect is generally what is being talked about when people refer to the greenhouse effect and climate change Burning fossil fuels such as natural gas, coal, oil, and gasoline raises the level of carbon dioxide in the atmosphere, and carbon dioxide is a major contributor to the greenhouse effect
The Greenhouse Effect The picture below shows the greenhouse effect Light from the sun passes through the atmosphere and is absorbed by the Earth's surface, warming it Greenhouse gases, like carbon dioxide, act like a blanket, trapping heat near the surface and raising the temperature It is a natural process that warms the planetThe answer lies in the greenhouse effect — gases in our atmosphere (including CO 2, CH 4 (methane) and H 2 O water vapor) trap much of the emitted heat and then reradiate it back to Earth's surface This means that the energy leaving our planet from the top of the atmosphere is less than one would expect given the known temperature of ourWHAT IS THE GREENHOUSE EFFECT The greenhouse effect is a natural phenomenon and is beneficial for us Certain gases in the atmosphere retain part of the thermal radiation emitted by the Earth's surface after being heated by the sun, this maintains the planet's temperature at a level suitable for the development of life Human action, however, has increased the presence of these
Greenhouse gases keep our planet livable by holding onto some of Earth's heat energy so that it doesn't all escape into space This heat trapping is known as the greenhouse effect Just as too little greenhouse gas makes Earth too cold, too much greenhouse gas makes Earth too warm Over the last century, humans have burned coal, oil, andThe effect is larger than in our simple model,Greenhouse effect and evidence of enhanced greenhouse effect The greenhouse effect The Earth's atmosphere acts like a greenhouse, trapping some of the energy from the Sun and keeping the planet warm
Graphic A simplified animation of the greenhouse effect En la gráfica se comparan los cambios en la temperatura de la superficie global (línea roja) y la energía del Sol que recibe la Tierra (línea amarilla) en vatios (unidades de energía) por metro cuadrado desde 10 However, the actual existence of a greenhouse effect was already known In 14, Joseph Fourier had written that 'the temperature of the Earth can be augmented by the interposition of the atmosphere, because heat in the state of light finds less resistance in penetrating the air, than in repassing into the air when converted into nonluminous heat'How the greenhouse effect works It's thought that the buildup of greenhouse gases impacts on global temperature in two ways The gases allow more of the sun's rays to enter the atmosphere
The greenhouse effect has supported life on the earth for millions of years Today, however, the greenhouse effect is growing stronger as human activities such as deforestation and fossil fuel use release more and more greenhouse gases into the atmosphere This traps greater amounts of the sun's radiation, which contributes to rising temperatures, also known as global warmingGlobal surface temperature increased 074 ± 018 °C during the 100 years ending in 05The Intergovernmental Panel on Climate Change (IPCC) concludes "most of the observed increase in globally averaged temperatures since the midtwentieth century is very likely due to the observed increase in greenhouse gas concentrations"via an enhanced greenhouse effectFigure 715 gives a total radiative forcing of 25 W m2 from increases in greenhouse gases since 1850 From our simple model, this forcing implies a change DTo = 08 K in the Earth's surface temperature, somewhat higher than the observed global warming of 06 K Simulations using general circulation models indicate values of l in the range 0314 K m2 W1 depending on the model;
The greenhouse effect is the term used to describe the warming of the Earth The diagram shows this If there were no greenhouse gases the Earth would be a frozen, lifeless ball in space, but too many gases and the planet warms up causing dangerous climate changeThe greenhouse effect is a warming of the earth's surface and lower atmosphere caused by substances such as carbon dioxide and water vapour which let the sun's energy through to the ground but impede the passage of energy from the earth back into space A simplified diagram illustrating the greenhouse effect (based on a figure in the 07 IPCCAbstract A distinction is made between the greenhouse effect and the increased or enhanced greenhouse effect The radiation budget of the atmosphere is reviewed, and a simple balanced model is designed permitting the calculation of a mean surface and a
The greenhouse effect is a warming of Earth's surface and the air above it It is caused by gases in the air that trap energy from the sun These heattrapping gases are called greenhouse gases The most common greenhouse gases are water vapor, carbon dioxide, and methane Without the greenhouse effect, Earth would be too cold for life to existThe greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without this atmosphere Radiatively active gases in a planet's atmosphere radiate energy in all directions Part of this radiation is directed towards the surface, thus warming it The intensity of downward radiation – that is, the strength of the greenhouse effect – depends on the amount of greenhouseThe most important greenhouse gases in Earth's atmosphere are water vapor, carbon dioxide(CO 2), and

Summary The greenhouse effect is a natural phenomenon that warms the Earth's surface and makes life on our planet possible However, human activities, especially the burning of fossil fuels, are increasing the levels of greenhouse gases in the atmosphere and causing the Earth to warm at a faster and higher rate Through demonstrations and simple models, students gain an understanding of the enhanced greenhouse effect The Greenhouse Effect The greenhouse effect is a naturally occurring phenomenon in which the specific gases in the atmosphere of the Earth trap heat from the sun (see The Greenhouse Effect Diagram attachment) Typically, our atmosphere absorbs just the right amount of heat so that living things can surviveLearn more Download for free Royaltyfree stock vector ID Natural and human enhanced Greenhouse effect diagram showing solar radiation and planet Earth Global warming, climate change Education for kids Cartoon vector illustration in flat style I By Inna Bigun
The greenhouse effect Without the greenhouse effect the mean temperature on Earth would be 18°C and there would be very little or no life So the greenhouse effect itself is a good thingAny change in the environment leading to additional and enhanced changes in that system is the result of a positive feedback mechanism Alternatively, if a change in the environment leads to a compensating process that mitigates the change it is a negative feedback mechanism and humanmade aerosols may confound the effect of greenhouse gasThe process of the greenhouse effect is quite simple and straightforward The sun emits energy toward earth's atmosphere Gases absorb heat and radiate some of it back to earth's atmosphere, making the surface temperature warmer The earth radiates energy from the sun (as infrared or longwave radiation) back to space
Greenhouse gases let the sun's light shine onto the Earth's surface, but they trap the heat that reflects back up into the atmosphere In this way, they act like the insulating glass walls of a greenhouse The greenhouse effect keeps Earth's climate comfortable Without it, surface temperatures would be cooler by about 33 degrees Celsius The greenhouse effect is the way in which heat is trapped close to Earth's surface by "greenhouse gases" These heattrapping gases can be thought of as a blanket wrapped around Earth, keeping the planet toastier than it would be without them Greenhouse gases include carbon dioxide, methane, and nitrous oxidesThe diagram gives more details about this process, called the greenhouse effect How the greenhouse effect works Electromagnetic radiation at most wavelengths passes through the Earth's atmosphere
Radiative forcing is the change in energy flux in the atmosphere caused by natural and/or anthropogenic factors of climate change as measured by watts / metre 2 It is the scientific basis for the greenhouse effect on planets, and plays an important role in computational models of Earth's energy balance and climateChanges to Earth's radiative equilibrium that cause temperatures toGreenhouse effect Step 1 Solar radiation reaches the Earth's atmosphere some of this is reflected back into space Step 2 The rest of the sun's energy is absorbed by the land and the oceans, heating the Earth Step 3 Heat radiates from Earth towards spaceEnhanced Greenhouse effect 'Greenhouse gases' are actually crucial to keeping our planet at a habitable temperature, without them the Earth would be about minus 17 degrees!
