The natural greenhouse effect The natural greenhouse effect is a phenomenon caused by gases naturally present in the atmosphere that affect the behaviour of the heat energy radiated by the sun In simple terms, sunlight (shortwave radiation) passes through the atmosphere, and is absorbed by Earth's surfaceGlobal warming or climate change is the rising of the earth's average temperature day by day caused by the presence of different gases along with carbon dioxide at high levels in the earth's atmosphere The greenhouse effect is essential for sustaining life on Earth The intensity of the warming effect depends on the concentration of the

The greenhouse effect is a natural process responsible for keeping the earth at the temperature needed to sustain life Acting just like the glass walls of a greenhouse, gases like carbon dioxide, methane, and nitrous oxide trap the sun's heat in the atmosphere and prevent itOn Earth, human activities are changing the natural greenhouse Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO 2)This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO 2To a lesser extent, the clearing of land for agriculture, industry, and other humanMain Greenhouse Gases Multiple gases contribute to the greenhouse effect that sets Earth's temperature over geologic time Small changes in the atmospheric concentration of these gases can lead to changes in temperature that make the difference between ice ages when mastodons roamed the Earth, and the sweltering heat in which the dinosaurs lived
This natural greenhouse effect is what keeps the Earth's climate livable Without it, the Earth's surface would be an average of about 60Greenhouse gas emissions increased 70 percent between 1970 and 04 Emissions of carbon dioxide, the most important greenhouse gas, rose by about 80 percent during that time The amount of carbon dioxide in the atmosphere today farCarbon dioxide (CO 2), which causes 9–26 percent;
The Earth's natural greenhouse effect and account for about 90% of the total heatretaining capacity of the atmosphere Greenhouse gases can also reabsorb solar radiation reflected or reemitted from Earth's surface, trapping the heat in our atmosphere instead of letting it escape to space The Greenhouse Effect is a natural process essentialAnd ozone, which causes 3–7 percentThe issue is how the strength of the greenhouse effect changes when humanThe 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 (ie, greenhouse gases) in a planet's atmosphere radiate energy in all directionsPart of this radiation is directed towards the surface, thus warming it
The 'greenhouse effect' is the warming of climate that results when the atmosphere traps heat radiating from Earth toward space Certain gases in the atmosphere resemble glass in a greenhouse, allowing sunlight to pass into the 'greenhouse,' but blocking Earth's heat from escaping into space The gases that contribute to the greenhouse effect As of 12, the warming effect of longlived greenhouse gases in Earth's atmosphere had increased by approximately 47% compared to 1990 Relative to preindustrial times, today's atmosphere absorbs an extra 3 watts of energy per square meterGreenhouse 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 is
The greenhouse effect happens when certain gases, which are known as greenhouse gases, accumulate in Earth's atmosphereGreenhouse gases include carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2 O), ozone (O 3), and fluorinated gases Greenhouse gases allow the sun's light to shine onto Earth's surface, and then the gases, such as ozone, trapMethane (CH 4), which causes 4–9 percent; Greenhouse effect is a concern for students due to the fact that they should know about the pros and cons of certain activities that involve heat radiation beyond the atmospheric level Greenhouse gases have reportedly elevated the mortality rate over the past many years
11 Is the greenhouse effect a natural or unnatural process?Planet Earth is billions of years old In its long life, it has undergone temperature shifts from ice ages to periods of global warming Yet overall, itEarth's natural greenhouse effect Earth's temperature begins with the Sun Roughly 30 percent of incoming sunlight is reflected back into space by bright surfaces like clouds and ice Of the remaining 70 percent, most is absorbed by the land and ocean, and the rest is absorbed by the atmosphere The absorbed solar energy heats our planet
Greenhouse Effect The greenhouse effect The greenhouse effect and climate change Effects of climatic change Resources The greenhouse effect is the retention by Earth ' s atmosphere in the form of heat some of the energy that arrives from the sun as light Certain gases, including carbon dioxide (CO2) and methane (CH4), are transparent to most of the wavelengthsNatural processes and cycles in the Earth system (Figure 1) These include the carbon cycle and greenhouse effect, orbital cycles, ocean currents that distribute warmer and colder water around the globe, and atmosphereocean interactions that moderate temperature Humans are principally affecting the climate systemWater Vapor is naturally occurring and accounts for 36%70% of the greenhouse effect Water vapor is vital to the greenhouse effect which sustains life on earth but, if the atmosphere warms with added carbon dioxide, this can increase the natural amount of water vapor in the air because more water vapor can evaporate into warm air than into
If the atmosphere works too well as a greenhouse, each day gets a little warmer and a little warmer We may not be able to measure this effect from day to day or even year to year But over tens of years, a few degrees of warming starts causing changes For example, ice melts in the North and South Pole regions12 How are the greenhouse gases and the glass walls of a greenhouse the same?Atmosphere & Greenhouse Gases The natural greenhouse effect is necessary for the temperature of earth to support current life systems The enhanced greenhouse effect caused by a greater buildup of carbon dioxide and methane (and other greenhouse gases) leads to less radiated heat leaving the atmosphere, resulting in warmer global temperatures
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 Figure nca3 3411 (left) A stylized representation of the natural greenhouse effect Most of the sun's radiation reaches the Earth's surface Naturally occurring heattrapping gases, including water vapor, carbon dioxide, methane, and nitrous oxide, do not absorb the short wave energy from the sun but do absorb the longwave energy reradiated from the Earth, keeping theOn Earth, the major greenhouse gases are water vapor, which causes about 36–70 percent of the greenhouse effect (not including clouds);

14 What is the opinion of most scientists about the greenhouse effect 15 Draw 2 pictures showing how the greenhouse effect and global warming workThe Earth's greenhouse effect is a natural consequence of the chemical makeup of its atmosphere If it were not for the greenhouse effect, life as we know it could not exist on Earth it would be too cold Our atmosphere is made mostly of nitrogen and oxygen, but also contains several other gases These include13 Why is the increase in greenhouse gases a problem?
Greenhouse Effects BIBLIOGRAPHY The natural greenhouse effect was first described by Joseph Fourier (1768 – 10) in 17 Solar energy reaches the earth in the entire spectrum The earth reemits this energy as infrared radiationGreenhouse gases in the atmosphere, such as water vapor and carbon dioxide, absorb outgoing infrared radiation and reemit it in any direction The greenhouse effect occurs when the sun's rays reach the Earth's atmosphere and the majority of the radiation bounces back out into space When this happens, a small portion is absorbed by chemicals in our atmosphere These are known as greenhouse gases By looking at air bubbles from hundreds of thousands of years ago until today 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 oxides
Both natural processes and humanbased activities The warming effect of trace gas greenhouse gas is enhanced by the effect of water vapour, which also absorbs infrared radiation, leading to an important natural feedback effect between anthropogenic greenhouse gas and water vapour (Figure 111) A certain level of greenhouse gas is The greenhouse effect is a natural process that has maintained Earth's temperature at a habitable level However, human activities — in particular, the burning of fossil fuels — release additional greenhouse gases into the atmosphere These additional gases increase the greenhouse effect, making Earth warmer than usual
