The treaty signed in 1992 was the Kyoto Protocol. It is a protocol to the United Nations Framework Convention on Climate Change (UNFCCC or FCCC), an international environmental treaty produced at the United Nations Conference on Environment and Development (UNCED) held in Rio de Janeiro, Brazil from 3-14 June 1992. It plans to gain awareness of global warming due to excessive greenhosue gases produced by countries all over the world.
The atmosphere. The ozone layer absorbs UV radiation, and atmosphere also controls temperature through the greenhouse effect, which allows the earth's temperature to be suitable for life. If there was no greenhouse effect then the earths average temperature would be -14oC instead of the actual 15oC.
Carbon dioxide is not normally harmful to plants, as it is the gas that they breath. However, excessive amounts, such as the possibilities that the greenhouse affect might cause, can greatly impair a plant's health. Think of it like Oxygen. We breath in oxygen, but breathing in excessive amounts of high concentrations of it can kill us.
The greenhouse effect is essential to life on earth. The enhanced greenhouse effect is not. In fact if it is enhanced too quickly it can be harmful to life.
Water vapor is not toxic, although it is a greenhouse gas.
atmosphere A+
Carbon dioxide (CO2).
At present man-made greenhouse gases, carbon dioxide (CO2) and methane, are adding to the greenhouse effect. The natural carbon cycle is unable to cope with the extra CO2 which remains in the atmosphere gathering heat, and causing global warming.
The burning of fossil fuels by nature releases harmful greenhouse gases.
No, greenhouse gases are useful for keeping the earth warm. In fact, they have kept the earth warm enough for life for millions of years.When levels of greenhouse gas increase in the atmosphere, then they are considered harmful, as they trap extra heat that is causing global warming.
The greenhouse effect will heat up the earth way too much, because of the gases sent up into the atmosphere, such as carbon dioxide and methane.
The greenhouse effect causes the earth's atmosphere to hold in more heat radiation than it should. It is caused by envirormentally harmful chemicals entering the atmosphere, like carbon dioxcide. This ,in turn, causes the global temperature to increase global warming.
Greenhouse gases like carbon dioxide are building up in the atmosphere and causing global warming.
No help. Greenhouse gases break down the ozone layer and allow harmful UV rays to hit the earth. The planet is getting hotter and we are seeing the results of it now.
Greenhouse gases aren't trapping heat it but letting more in. The Earth's atmosphere blocks out most of the suns heat and harmful rays. With the gases polluting the world, the atmosphere is slowly weakening, letting more and more heat through.

Not in small concentrations.
