what is green house effect?
359692
The radiations emitted from the sun and also the earth are usually blocked by layers of atmospheric gases and prevent them from escaping into space.This causes 'GLOBAL WARMING'-due to the reflected radiations.This is also known as 'GREEN HOUSE EFFECT'.

Solar Energy\n* inexpensive (free, only maintenance costs of the device)\n* does not work well on cloudy days or days when the sprayers fly, or does not work at all (needs electric back up)\n* Active solar: e.g. the heat is forced down from the ceiling, gathered by voltaic cells (solar panels). \n* Passive solar, a wall within a glass enclosure is painted black and absorbs the heat (green house effect maximized). Warm air can blow through a hole in the upper black wall into the room behind the black wall.\n* Solar energy prevents pollution.\n* Solar energy does not drain the oil reserves of the earth.\n* There are solar warm water heaters, heaters and cookers.\n* Solar cookers and passive solar can be self-made.\n* Solar energy is used simply by opening the curtains and letting the sun shine on tile floor.\n\nLet the sun shine and the skies again be blue!\nCordially, India.Magica

I dont know the seriousness in your question but for one, I hate the cold so plz dont suggest puttin the sun off and two, green house gases that TRAP HEAT causes global warming. Not the sun (and yeah yeah, the sun gives off heat, but so does machinary, body heat, lab exothermic reactions, weapons of mass destruction, fires etc)

The chloroplast cells absorb all other colors besides green. So green is reflected...

There is a great PDF file that is listed below from the EPA (Environmental Protection Agency) that may be useful to you.  It explains that little things may have a huge impact on global warming if they are widely accepted.  Recycling, fuel-smart cars, solar power, planting trees are all ways of improving the environment and reducing the impact of global warming.

Greenhouse effect:  \nIn our atmosphere, we have something called greenhouse gasses.  They exist naturally, and two examples of greenhouse gasses are water vapour and carbon dioxide (there are several more of them).  The greenhouse gasses cause some of the heat that is emitted from the earth to stay within our atmosphere.  If there were no greenhouse gasses in the atmosphere, all the heat from the earth would radiate out into space.  This would mean that the average temperature of earth would be -18 degrees Celsius (0 degrees Farenheit) instead of +15 deg C (60 deg F).  That's a huge difference - I doubt that there would be human life on the planet earth without the greenhouse effect!\n\nGlobal warming:  \nWhen people talk about global warming, they mean that the amount of greenhouse gasses in the atmosphere increases.  Some people say that changes occur naturally, some people say it's because we pollute the air with carbon dioxide etc.  An increase of greenhouse gasses in the atmosphere would mean that less of the heat from the earth would radiate into space, which gives an increase in the average temperature on earth.  Rising temperatures could mean, for instance, that some of the polar ice melts, causing flooding in coastal countries.\n\nSo:\nGreenhouse effect - a good thing\nGlobal warming - possibly bad

I have heard it as "for every action, there is an equal and opposite reaction" As for people and environment.  Someone cuts down a forest- what happens? Soil biodiversity changes, animal species in that area change, CO2 consumption in that area decreases.\n   People put more black top up- absorbs and reflects heat warming the earth's surface more. There are a ton of examples, I am not sure what you are looking for specifically.

Define pollution.  \nFrom what baseline are you asking if it has increased?\n\nClearly in the earths past the atmosphere was so "polluted" with various noxious gasses that it was incapable of supporting complex multicellular life forms.\n\nFrom that baseline we are doing very well.\n\n(for a less flippant answer the US and EU countries produce much less green house gasses per capital then they did 10,20, or 30 years ago.  The "problem" is that China and India are industrializing rapidly and have little in the way of environmental safe guards)

The principle behind global warming is the same as the process that warms the interior of a greenhouse. Light from the Sun passes relatively easily down through Earth's atmosphere to the surface. Earth's surface warms and radiates heat in the infra-red part of the electromagnetic spectrum. These frequencies don't pass back up through the atmosphere easily but instead are retained by the atmosphere, thus warming it.

There are many reasons why feces can be green. For one thing, it can be because of food you ate. Green, leafy vegetables contain chlorophyll, which can color the stool green. Foods that have certain kinds of additives, such as artificial flavors or colors, may also have a greening effect. It could also mean that the stool passed too quickly through the large intestine. If it continues, please see your doctor.

Greenhouse Effect, the capacity of certain gases in the atmosphere to trap heat emitted from the Earth’s surface, thereby insulating and warming the Earth. Without the thermal blanketing of the natural greenhouse effect, the Earth’s climate would be about 33 Celsius degrees (about 59 Fahrenheit degrees) cooler—too cold for most living organisms to survive.\n\nThe greenhouse effect results from the interaction between sunlight and the layer of greenhouse gases in the Earth's atmosphere that extends up to 100 km (60 mi) above Earth's surface. Sunlight is composed of a range of radiant energies known as the solar spectrum, which includes visible light, infrared light, gamma rays, X rays, and ultraviolet light. When the Sun’s radiation reaches the Earth’s atmosphere, some 25 percent of the energy is reflected back into space by clouds and other atmospheric particles. About 20 percent is absorbed in the atmosphere. For instance, gas molecules in the uppermost layers of the atmosphere absorb the Sun’s gamma rays and X rays. The Sun’s ultraviolet radiation is absorbed by the ozone layer, located 19 to 48 km (12 to 30 mi) above the Earth’s surface.\n\nAerosols, also known as particulates, are airborne particles that absorb, scatter, and reflect radiation back into space. Clouds, windblown dust, and particles that can be traced to erupting volcanoes are examples of natural aerosols. Human activities, including the burning of fossil fuels and slash-and-burn farming techniques used to clear forestland, contribute additional aerosols to the atmosphere. Although aerosols are not considered a heat-trapping greenhouse gas, they do affect the transfer of heat energy radiated from the Earth to space. The effect of aerosols on climate change is still debated, but scientists believe that light-colored aerosols cool the Earth’s surface, while dark aerosols like soot actually warm the atmosphere. The increase in global temperature in the last century is lower than many scientists predicted when only taking into account increasing levels of carbon dioxide, methane, nitrous oxide, and fluorinated compounds. Some scientists believe that aerosol cooling may be the cause of this unexpectedly reduced warming. \n\nEffects:\n\nThe increase in global temperatures is expected to result in other climate changes including rises in sea level and changes in the amount and pattern of precipitation. Such changes may increase the frequency and intensity of extreme weather events such as floods, droughts, heat waves, and hurricanes, change agricultural yields, cause glacier retreat, reduced summer streamflows, or contribute to biological extinctions. Although warming is expected to affect the number and magnitude of these events, it is difficult to connect any particular event to global warming.\n\nThe predicted effects of global warming are many and various, both for the environment and for human life. These effects include sea level rise, impacts on agriculture, reductions in the ozone layer , increased intensity and frequency of extreme weather events, and the spread of disease. In some cases, the effects may already be being experienced, although it is impossible to attribute specific natural phenomena to long-term global warming. In particular the relationship between global warming and hurricanes is still being debatedFour new papers correlating climate change with increased hurricane intensity seem to be making the case that the two phenomena are linked , a draft WMO statement acknowledges the different viewpoints .
