There are natural greenhouse gases of water vapor and carbon dioxide that have kept the earth warm for millions of years. Humans are not causing them.
But the greenhouse gases that are contributing to the enhanced greenhouse effect which is causing global warming are being emitted by the following human actions.
- Burning fossil fuels (coal, oil and natural gas) in industry, transport and to generate electricity.
- Deforestation. We need trees to suck carbon dioxide out of the air.
- Cattle raising. Forests have been cut down for pasture and the animals belch methane (a greenhouse gas 21 times stronger than carbon dioxide).

∙ 12y agoScientific evidence indicates that the levels of Carbon Dioxide (a major Greenhouse Gas) have doubled since the start of the industrial revolution. The cause is unquestionably the increased use of fossil fuels by humans.
Burn coal and fossil fuels for energy. Also cutting down the forest, raising cattle and making cement.

Why is a greenhouse gas considered a greenhouse gas?
if you're asking why are the collective gases that are damaging the atmosphere called greenhouse gases the answer iswhen sun rays enter the earth to warm it up, when they try to leave the greenhouse gases reflect them back again stopping them from leavingthe earth is slowly heating up from this (global warming) and so people blame the greenhouse gases (which mainly humans are causing)we have called them greenhouse gases because the process of blocking the sun rays from leaving is the same technique that greenhouses use.
Production of greenhouse gasses?
The production of greenhouse gasses is harmful to the environment, causing an enhanced (or accelerated) greenhouse effect which is causing global warming. The gases emitted include methane and carbon dioxide.
Why should greenhouse gases be reduced?
Because they are causing global warming and climate change.
What are anthropogenic greenhouse gases?
Anthropogenic means made by humans, so the greenhouse gases caused by man are mostly carbon dioxide and some methane, and some CFCs.
What is the concentration of greenhouse gases in the air?
The concentration of greenhouse gases in the air, largely water vapor, carbon dioxide and methane, are causing an enhanced greenhouse effect which is global warming.The amounts of greenhouse gases in the air are:5% Water Vapor0.039% CO2Trace (less then 0.001%) small amounts of other gases (methane, nitrous oxide etc)Water vapor absorbs heat like other greenhouse gases.
What greenhouse gases do in the atmosphere?
Greenhouse gases keep the earth warm.Too much greenhouse gas is causing global warming.
Why might an increase in the concentration of greenhouse gases be concern?
Because it is all but certain that this increase will be extremely detrimental to the Earth's Future. Additional greenhouse gases are causing an enhanced (or accelerated) greenhouse effect which is causing global warming.

What is the largest effect on how humans interact with the environment?
Perhaps the major effect that humans have on the environment is the pollution of the atmosphere. The greenhouse gases in this pollution are causing temperature rises all over the world.
What is the effect of higher levels of greenhouse gases?
More greenhouse gases trap more heat in the atmosphere, causing a global warming and climate change.
How might greenhouse gases cause climatic changes?
The build up of greenhouse gases is trapping more heat, causing global warming and climate change.
Why are increased greenhouse gases not good for the earth?
Because it is all but certain that this increase will be extremely detrimental to the Earth's Future. Additional greenhouse gases are causing an enhanced (or accelerated) greenhouse effect which is causing global warming.
What are the hazardous greenhouse gases?
Carbon dioxide and methane are the ones causing most of the accelerated greenhouse effect that is causing global warming and leading to climate change.
Production of greenhouse gasses?
The production of greenhouse gasses is harmful to the environment, causing an enhanced (or accelerated) greenhouse effect which is causing global warming. The gases emitted include methane and carbon dioxide.
Why should greenhouse gases be reduced?
Because they are causing global warming and climate change.
Greenhouse gases absorb UV energy causing the troposphere to heat up?
TRUE

Anthropogenic means made by humans, so the greenhouse gases caused by man are mostly carbon dioxide and some methane, and some CFCs.
