Water vapor is responsible for 95% of the greenhouse effect. How can we reduce our output of it?
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:
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?
So, are you saying the planet is doomed, within about 100 yrs, without recourse?
Stop boiling water for tea. Shut down Starbuck's.
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.
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.
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.
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.
