Global warming caused by which gas?

Question

is carbon di oxide causing global warming

Answer 1

caused by many green house gases including carbon dioxide, water vapour,  methane, nitrous oxide, and ozone

Answer 2

There is now little doubt that it's a contributor, but water vapor is even more effective in creating a "greenhouse effect" than CO2.

Just how much the quantity of CO2 in the atmosphere is contributing to global warming is still a matter of debate. Sure, it's a factor but it can't be considered on its own as if it is the *only* factor. If you research "factors in global warming" you'll see what I mean.

On the other hand, I think it's perfectly reasonable that we should do what we can to reduce excess CO2 emissions.

Answer 3

dead trees, dead leaves, dead sticks world wide is the gases that's causing the problems.  Man needs to clean up mother nature

Answer 4

CO2 is a major Green house gas next to water vapor,which causes about 9-26% of Green house effect [global warming].

An increase of 1ppm of CO2 every year in atmosphere has been estimated.

Answer 5

global warming is caused by greenhouse gases- carbon dioxide, water vapour, methane, nitrous oxide. actually these gses are beneficial to maintain life but only when their proportio in the atmosphere is disturbed i.e increase by pollution etc. they cause warming of the atmosphere by trapping the infrared rays in the atmosphere. this is global warming.

Answer 6

Carbon dioxide and methane are the two major culprits

Answer 7

Scientist are not really sure. The sun is having a higher output of solar radiation and we are coming out of an ice age.

Answer 8

Almost all of the Earth's atmosphere (99%) is made up of nitrogen (about 78%) and oxygen (about 21%). While both of these gases play important roles in the vast number of processes that support life on Earth, they play almost no direct role in regulating the climate. This is carried out by some of the trace gases in the remaining 1% of the atmosphere which occur in relatively small amounts.

Greenhouse gases include in the order of relative abundance water vapour, carbon dioxide, methane, nitrous oxide, and ozone. Greenhouse gases come from natural sources and human activity. The major greenhouse gases that humans produce are CO2 and methane but we produce other one too.

Energy from the sun reaches earth’s surface as infrared energy, the heat is then radiated back up into the atmosphere. Greenhouse gases have special properties that trap some of this heat, without them earth would be about 35 degrees Celsius colder that it now is. Increasing the amount of these greenhouse gases means that more heat is trapped in the atmosphere.

Climate and weather are influenced by rises and falls in temperatures, that’s why the result of global warming is called climate change.

At present humans are burning each year an amount of fossil fuels (oil, gas, coal) that earth took a million years to produce. This is much higher than at any point in earth’s history and is on top of the amount that earth naturally produces itself, by volcanic activity for example.

Answer 9

Noone's really sure,though CO2 does contribute to it.

Answer 10

Dunno! Water vapour is many times more effective as a greenhouse gas! CO2 is good for plants! As much as I love winter, I'd sooner global warming than global cooling!

Kinda hard to grow rhubarb on a snow bank!

Answer 11

obviously not CO2 because the greenhouse effect has been proven wrong... if the majority of the warming of the current warming cycle occured before world war 2 how could it be true?

Answer 12

CO2 is the main culprit in global warming, although the most abundant green house gas is actually water vapor, but CO2 accumulates in the atmosphere, causes a small increase in temperatures, which causes increase in water vapor, accelerates global warming, and warmer climate also means that another green house gas, methane, starts evaporating faster, and joining the other green house gasses in the air.
