What else besides volcanoes release natural gases or in this case carbon dioxide?

Question

This is just for a little global warming essay thingymabob and i was wondering what else releases natural gases. Plz help

thnx!

Answer 1

All respiring organisms, cars, power stations etc all emit carbon dioxide.

A list of everything that emits "natural gases" would be a tad long.

Answer 2

All plants and animals release CO2 as they breath. All burning releases CO2. What are you referring to as natural gases? Cows and other ruminants (animals with4 stomachs to digest grasses) release methane, a natural gas that does effect global warming, through their intestinal tract.  Some springs release sulfur dioxide and hydrogen sulfide. Decomposition of all wastes releases CO2 and other natural gases. So landfills release methane and CO2 as well as others.

Answer 3

Carbon dioxide is put into the air in a number of ways.

1. Fires (such as forest fires)

2. Respiration (Organisms breathing)

3. Decomposation of dead animals/plants

4. Fuel Burning (gasoline, coal, etc)

Answer 4

Animals release natural gases.  Cattle produce huge amounts of methane and other gases.  All animals produce carbon dioxide, just by breathing.  Swamps produce various gases, especially methane.

Thawing permafrost releases gases, including CO2 and methane.  This is considered one of the biggest dangers to global warming, once it starts it will add to the  warming and so add to the thawing rates.

Deforestation by any method adds gases.  Deforestation by fire adds CO2 at an incredible rate and like permafrost thawing feeds upon itself, provoking more heating which provokes more fires.  

Burning all fossil fuels adds natural gases but not by what most people consider natural methods.

Answer 5

The break down of dead animals/plant. Crude oil is made from remains of animasl and plants, during this porcess Methane is made, thats a natural gas.

Answer 6

The ocean is by far the largest natural emitter of carbon dioxide.    Volcanoes are a tiny tiny fraction of the anthropogenic carbon emissions, which in turn are only about 5% of the CO2 emissions from the ocean.  In terms of atmospheric CO2 sources, you can neglect volcanoes entirely and do a great job modeling CO2 cycling in the atmosphere.
