Define the greenhouse affect? How important is it?

Question

I think the greenhouse affect has to do with the pollution eating away the ozon layer, but i'm not sure.

Answer 1

The greenhouse effect is a well-known and necessary environmental process. Simply put, greenhouse gases (water vapor, carbon dioxide, methane) trap heat and keep it from escaping back into outer space.

Without the greenhouse effect, temperatures would be 30 degrees celsius colder (54 degrees F), so the effect is EXTREMELY important to us.

The greenhouse effect has nothing to do with the ozone layer.

The ozone layer is our barrier against ultraviolet radiation.

Pollution is the common factor here. Even though carbon dioxide isn't classified as a pollutant by the U.S. Government, it is a by-product of industry and automobiles.

Carbon dioxide "pollution" is contributing to the greenhouse effect.

Meanwhile, CFC pollution contributes to the thinning of the ozone layer.

Answer 2

The greenhouse effect states that certain gases (H2O, CO2, CH4, etc.) trap heat (IR radiation) that would normally radiate away from the earth and warm it. These gases are increasing, causing increased warming. The ozone layer depletion is actually unrelated: this is from CFCs which break down ozone and allow excess harmful UV radiation to hit the earth. The only connection is CFCs and substitutes also increase the greenhouse effect at the same time.

A certain low-level of this is required to keep the earth warm, but with increasing greenhouse gases, the earth is warming unaturally. The extreme situation is Venus, which has a run-away greenhouse effect, and is inhostpitable because of it.

The US must ratify the Kyoto protocal, being the first step toward doing something about this global problem which we are cheifly to blame.

CO2 is 30% higher than it has been for 650,000 years. Methane is 130% greater. These are two of the main pollutants humans put into the atmosphere in excess, and they are two of the primary greenhouse gases.

Look at the 'hockeystick', which shows a dramatic warming since 1950 after a fairly stable climate for 1000 years. In fact, the 10 hottest years in recorded history have all happened since 1990, with 2005 being the hottest, and 2006 is shaping up to maybe break that record.

There has NEVER been an article doubting man's influence on global warming published in a peer-reviewed journal. A recent study of almost 1000 proved that.

Yes, the earth naturally heats and cools, but the rate and amount we are warming now is unprecedented in the recent geologic past. We are doing this, and we must stop it. This is not some political statement or rhetoric. This is science trying to educate a crass, ignorant public of the damage they are doing. The magnitude of temperature increase ALREADY is about 10x that of the 'little ice age' of the middle ages, and rate and amount are only going up.

Just to be clear, glacial and interglacial cycles are mainly controlled by astronomical fluctuations, but we have a detailed record of the last 7 cycles, and what the climate and CO2 is doing now is way different and extreme. The rate of increase is much higher than in the past AND the value itself is much higher.

Answer 3

production of Methan from the Intestinal Tract of the cattle is between the justifications of greenhouse outcome. Methane is 70 in efficiency in evaluation to CO2 at one hundred. Methane is likewise shaped from manure and from the waste dumps for cattle. To counter this, planting of timber should be persisted, and protection of latest forests is significant. the bigger individuals to toxins in the cities is Industries and autos the position the volume of Carbon releazed is measured in billions of a great deal in holding with anum. united states and China make contributions the biggest with India and different international places between the right few.
