Greenhouse Effect is the result of the ability of certain gases in the atmosphere to trap heat from Earth's surface, causing the planet to warm. Without this thermal blanket of insulating gases, Earth's climate would be more than 30°C cooler and few organisms would survive on the planet. Some scientists believe that humans have increased the greenhouse gases by burning wood and using petroleum products, and that this affects global warming. Although Earth is known to have gone through cycles of heating and cooling for many millions of years, they are concerned that there has been an increase in Earth's surface temperature of about 0.6°C over the last 100 years.

JudyThe greenhouse effect is called so because it functions in a similar way to a greenhouse. Greenhouses allow sunlight to enter and trap heat inside, creating a warm environment for plants to grow. Similarly, the greenhouse effect refers to the way Earth's atmosphere traps heat from the sun, leading to a warming of the planet.

Is global warming same as green house effect?
No, Green house effect is the phenomenon when the green house gas would trap solar radiation. Mostly it could trap (absorb) radiation on infrared region better than visible range and so it result to higher temperature of this planet. The Global warming is the theory that earth temperature is increasing due to man made emission of CO2 through process of Green house effect.
Are human farts detrimental to the 'greehouse' effect?
No. The process of farting is age old and it has nothing to do with green house effect. (Even if is so, you do not have an option of stopping the process of farting.)
What effects do the green house gases have?
When in the atmosphere, they "trap" or reflect back outgoing infrared radiation (that Earth would normally shine out into space) so that the average heat loss of the Earth is reduced. This causes the atmosphere to heat up slightly. This is called "global warming" They are called "greenhouse gasses" because the glass in a greenhouse has a similar effect, warming the inside of the greenhouse by trapping the Sun's heat.
What process transfers light energy to chemical energy in a green house?
Photosynthesis, same as outside the green house. So why do we use green houses? The green house is used to raise the temperature so that the plants start growing and are not killed by cold. It does this is two ways, by constricting air flow and blocking infrared light. The major part of this is that outside the green house, when the soil absorbs solar energy and turns it into heat, the air will transport that energy away which cools the soil and the plants growing in it. In the green house the warm air is trapped. To some (small) extent glass will block ultraviolet and infrared rays more than visible light. This stops harmful UV rays from hitting the plants, and it traps the infrared heat emissions from the plants inside the green house. Actually there is less useful sun light energy reaching the leaves within a green house than if the plants were outside it (try sunbathing under glass) but better control of temperature and humidity allows the plant to grow better anyway.
Does rubbing alcohol freeze like the Mpemba effect?
1. Today the Mpemba effect remain unclear and possible not true. 2. I suppose that any link exist between the so called Mpemba effect and the freezing of rubbing alcohol.
