Water vapor is responsible for 95% of the greenhouse effect. How can we reduce our output of it?

Question

The other greenhouse gases: carbon dioxide, methane, nitrogen dioxide, and various others including CFCs, contribute only five per cent of the effect, carbon dioxide being by far the greatest contributor at 3.6 %.

However, carbon dioxide as a result of man's activities is only 3.2 % of that 3.6, hence only 0.12 % of the greenhouse gases in total. Human-related methane, nitrogen dioxide and CFCs etc make similarly minuscule contributions to the effect: 0.066, 0.047 and 0.046 % respectively.

So is there really anything humans can do to effect the situation at all, positively or negatively?

Answer 1

Once, just once, I wish a GW denier would get his facts right.

Although water vapor makes up about 90% of GHG molecules, its effect is LESS than CO2 per molecule. Thus water vapor is NOT responsible for 95% of the greenhouse effect, nor even close. The actual number is between 36% and 66%. The large range is because the various GHG's overlap their coverage in various wavelengths.

This raises two important questions:
1) Who's been lying to you, and why?
2) Why should you (or anyone else) believe somebody who can't get the first thing right about global warming?

Answer 2

I examine some replys on your intial question and am somewhat uninterested with the phobia mongurs. in case you google globel warming history you will see what has exceeded off in the previous few many years. we've been slipping into an ice age to boot as been messing up the envirnment invariably. Time magizine featured hide memories approximately us slipping right into a mini ice age as modern-day as 1970 ish. we are screwing up the ambience for a form of motives however the call is annoying to detirmine if we are at the instant affecting something. there are one in each and every of those great variety of aspects that result this that our (human beings) little foot print on the international is relatively inflicting something. think of appropriate to the dirt bowl or the winters of the late 70's early 80's in the midwest u . s .. final analysis is that we are undesirable for the planet for a form of motives yet climate types are plagued via extra desirable than purely the autos we force or how intense we shop our thermostats.

Answer 3

I suppose you could give up all outdoor water use, like lawn watering, swimming pools, decorative fountains, and things like that. It is called xeriscaping. A no-water landscape. And of course crop irrigation will contribute a lot of evaporation, but giving that up would cause world wide starvation. And I suspect that agriculture contributes 90+% of the man made evaporation, so there is not really much we can really do about it.

Answer 4

I am still waiting for a single person to tell me why global warming is a bad thing. I like the idea of a longer growing season and being able to grow crops where none would grow before.

Answer 5

There is nothing you can do because, as this shows, its not man-made. And just as life on earth survived other warm periods, so too will it survive now. In fact, look at the tiem period around 1000AD...humanity was at a peak then...it got cold after that, and humanity went to pot.

Answer 6

Stop boiling water for tea. Shut down Starbuck's.

Answer 7

So, are you saying the planet is doomed, within about 100 yrs, without recourse?

Answer 8

LOL......well now this is a strange question.
Do you think watering our yards is doing it?
Look North young man........forget about west its drying up.
