how did the green house effect start

The sun and sunspots cause heating and cooling. The atmosphere causes the heat retention. Without it the entire earth would be very hot (several hundred degrees) during the day and very cold (minus several hundred degrees) at night.
Obviously there is nothing we can or should do about it. Without the greenhouse effect there would be no human life on earth.
Water vapor is the majority of the greenhouse gasses. Carbon-dioxide comes in a very distant second.
Al Gore is making a very good living frightening the public about a natural phenominon that is not a problem. In the 30's we had the "dust bowl" in the US. In the 70's the same "scientists" were warning us about the comming ice age (read the reference, it's from Time magazine). In the 1300's they grew grapes in england and greenland had farms.
Don't believe all of the hype.

The green house effect is when one form of energy (light) passes through an object (air), is transformed into another form of energy (heat) but it trapped because that new type of energy (heat) can't pass easily back through the same object (air).
When it comes to the earth, it has had a greenhouse effect ever since it first had an atmosphere, so that is when it started.
Recently (within the last 50 years or so) some scientists have come up with and studied theories that pollution increases the greenhouse effect by a dangerous amount. This is extremely difficult to prove, and if it is true we probably won't know until it is too late, so many people are trying to reduce pollution to try to prevent this problem, or at least delay the problem until we know if it really is a problem or not.

It is caused by gases that are opaque to infared radiation, these include CO2, H2O, CH4. The effect started the moment the Earth condensed from a cosmic cloud, and without some green house effect, life as we know it would not be possible on this planet.

Some gases in the atmosphere are transparent to visible light, but block heat. They let sunlight in and block the resulting heat. That's the greenhouse effect. It's like how the glass in a greenhouse keeps plants warm in winter. It's largely natural, desirable, and caused by water vapor.
Global warming is excess greenhouse effect caused by man, chiefly through burning fossil fuels and making carbon dioxide. It threatens to cause very costly flooding and serious damage to agriculture.

eco-friendly domicile result has constantly been right here. a minimum of, ever by way of fact there became an ecosystem. that is led to by utilising our environment battling the warmth from escaping decrease back into area. devoid of eco-friendly domicile result we would be as chilly as Mars. international warming as a effect of eco-friendly domicile result, is a greater moderen progression led to by utilising burning fossil fuels and overloading the ambience with carbon dioxide. The greater carbon dioxide contained in the ambience, the greater warmth is trapped. This in all likelihood have been provided that is start up in the time of the commercial age (18th - nineteenth century) and has bigger by way of fact the inhabitants bigger.

Increased green house gases (Mostly carbon dioxide) in the atmosphere.

green house effect does'nt have anything to do with global warming. green house is only blamed by humans for a excuse like exhaust is but neither is true.
