Carbon dioxide is largerly responsible for the greenhouse effect true or false?

Question

Carbon dioxide is largerly responsible for the greenhouse effect true or false?

Answer 1

It certainly is a major component, and the most commonly cited.  Methane is much more potent as a green house gas and animal herds produce lots of it.  But water vapor is the most common and strongest overall.  Normally it isn't mentioned since its levels are usually part of the normal background.  Human activities are not responsible for water vapor levels like they are for CO2 and methane.

(from wikipedia )The most important greenhouse gases are:

    * water vapor, which causes about 36–70% of the greenhouse effect on Earth. (Note clouds typically affect climate differently from other forms of atmospheric water.)

    * carbon dioxide, which causes 9–26%

    * methane, which causes 4–9%

    * ozone, which causes 3–7%

    Note that this is a combination of the strength of the greenhouse effect of the gas and its abundance. For example, methane is a much stronger greenhouse gas than CO2, but present in much smaller concentrations.

Answer 2

True.  It is the most common greenhouse gas.

Answer 3

i think thats true...

Answer 4

False water vapor accounts for 90% of the greenhouse effect.

I believe your teacher would want a true answer, but the question is not what is causing the temperature to rise, but what is the most responsible for the greenhouse effect.  Although the link below disagrees with my 90% it does say water vapor is the major greenhouse gas.  (the disagreement has to do with clouds not being counting with the rest of the water vapor.)

Answer 5

False, most of the Green House Effect is caused by water vapor. We all know that clear cloudless nights are often frosty and cold, without an insulating blanket of clouds. However, this does not obviate human responsibility. The Earth's atmosphere is a subtly balanced and interrelated system; it is predicted that more atmospheric Carbon Dioxide will increase global warming, and warming will increase evaporation rates and the amount of water vapor in the atmosphere. This could result in a dangerous feed back loop of increased temperatures, storminess and flooding.

Answer 6

The Earth receives energy from the Sun in the form of radiation. The Earth reflects about 30% of the incoming solar radiation. The remaining 70% is absorbed, warming the land, atmosphere and ocean. For the Earth's temperature to be in steady state so that the Earth does not rapidly heat or cool, this absorbed solar radiation must be very closely balanced by energy radiated back to space in the infrared wavelengths. Since the intensity of infrared radiation increases with increasing temperature, one can think of the Earth's temperature as being determined by the infrared flux needed to balance the absorbed solar flux. The tipping point in global warming is the point at which change due to human activity brings about sufficient new processes in nature to make any human reversal of the change impossible. Some climate scientists believe this will be reached in about 2017, while others, notably James Hansen, NASA's top climate scientist believe it has already been reached. Water vapor can be thought of as providing 36% of the greenhouse effect, and carbon dioxide 9%, but the effect of removal of both of these constituents will be greater than the total that each reduces the effect, in this case more than 45%. Scientists need only look and study Venus and Mercury to view the effects of run-a-way greenhouse effects.

Answer 7

False.. carbon monoxide is largely responsible.. when carbon monoxide collides with ozone.. it will produce oxygen and more carbon monoxide. (I think :))
