lol, you mean clouds?Is that a variable?

The "disingenuous" chart actually did cover water vapor/clouds to the extent that they're variable:"stratospheric water vapor from methane""aerosols: effect on clouds"[Edited on June 24, 2008 at 10:44 AM. Reason : .]

so what effect are you saying water vapor has on the idea of global warming? We should just assume that it'll be a negative feedback and just fix any change we introduce?Maybe we should fund some scientists or something to investigate the effect of this...

6/24/2008 11:05:41 AM
yeah thats almost as dumb a question as "how is it a natural variable"seriously...water vapor...biggest impact of any gas on the greenhouse effect on planet earth...look it up...i dont have time for your idiotic trolling and complete idiocy on this topic as usualmaybe if you ever had the ability to look at this from a scientific perspective instead of a political perspective (and if you understood science in the first place) you wouldnt always come across as the biggest moron in every climate change thread that you post in]
6/24/2008 11:07:12 AM
Water vapor insulates the Earth. We know that.But how could it be responsible for an increase in Earth's temperature? Did the evaporation point of water suddenly drop over the past couple decades?
6/24/2008 11:12:44 AM
let me simplify it even more for you so you might understand1. Is water vapor a greenhouse gas?2. If so, wow come only CO2, NH4, and N2O are listed on the chart as greenhouse gases ("The Major Forcings)"?]
6/24/2008 11:25:13 AM
Because they're variables.In that, their concentrations have varied.Is it starting to sink in?
6/24/2008 11:27:08 AM
i guess you dont want to answer my two straightforward questions...i dont know how much more simply i could phrase them(co2, nh4, and n2o concentrations also obviously vary...)I'd love for you to find something that explains why we shouldn't factor h2o into the greenhouse effect just like we do the other greenhouse gases]

how is water vapor not a variable???? please explain
6/24/2008 11:33:53 AM
It's a result of pressure and temperature. Not a cause.
6/24/2008 11:35:56 AM
i'm gonna call bullshit on that.i mean, i dont' know the intricacies of climate modeling, but i know about chemical models, and the individual components of a gas mixture (say for instance water vapor in air) are usually variables, or at least they can be in a more complete model of the reaction/mixture.

6/24/2008 11:42:53 AM
^^ Well I'm sure it's something that was tested-- but apparently it's undergone no significant change and has no significant impact.So I'm still wondering how water vapor could be the variable that's causing climate change? Did water suddenly start evaporating at lower temperatures?
6/24/2008 12:01:17 PM
boone, tsk tsk on the strawman. we were merely saying that it is a variable in the complex system of the climate.
6/24/2008 12:05:31 PM

^So then explain to me how it's causing climate change.[Edited on June 24, 2008 at 12:17 PM. Reason : ^^ strawman to you, not tree.]
6/24/2008 12:16:33 PM
well water vapor has much more of a warming effect on our planet than co2 doesyour claim and many others' claim is that co2 is the cause of climate changewater vapor affects the climate much more than co2...yet its not even mentioned in that disingenuous chart? dont you see something wrong with this picture? leaving out the most important greenhouse gas? the most important variable?]

Well, human industry does introduce a lot of water vapor into the atmosphere. Hell, a power plant operating its cooling towers on a hot day probably evaporates more water than all the lakes in North Carolina. Not to mention all the water vapor produced by burning natural gas, oil, coal, etc. All this extra water vapor should have a warming effect on the planet, but other than the fact that we keep putting more in it should be a non-compounding effect. Of course, if only the world's plants could keep up then the CO2 we pump into the air would also be a non-compounding effect.[Edited on June 24, 2008 at 12:36 PM. Reason : .,.]

couldn't global warming also be introduced by all the exothermic reactions that man made processes utilize. Harris lake is remarkably warmer than it would be naturally bc of the nuclear power plant.
6/24/2008 1:10:21 PM
and boone resorts to posting an obsessive picture and finally gives up his trollinghe only wasted an entire half of a page all because of his refusal to even acknowledge that water vapor was a variable in climate change models...i ask mrfrog (who actually understands science) why water vapor isnt in the chart...and boone acts like aerosols are water vapor and then proceeds to call me out for not knowing what a variable is when its clear he is the clueless onei really dont know why he posts in this thread at all when its clear how little he understands about science

99.99% of the water vapor in our atmosphere is in the troposphere (the lower level where all the weather occurs)the NH4 water vapor in the stratosphere is at maximum 0.01% of the water vapor in the atmosphereso no I wouldn't say that chart listed all the factors
6/24/2008 1:39:01 PM
They were listing the factors causing forcing.Apparently low-level water vapor isn't having a net effect.

Water vapor...Yeah it's there. Does it change? Yes. Did human activity change it? Yes.However, why it's changing is very strongly misrepresented on this page. Water vapor rains down, CO2 does not, even though it is absorbed more slowly by trees, oceans, etc. So, we have direct emissions of water vapor, you breathing right now for instance. We also directly add to the heat production term of the Earth. Both of these, however, are a drop in the bucket compared to the net heat flows through the Earth.Harris lake has a cooling tower next to it that produces water vapor and a power plant that directly produces heat. But both of these factors PALE in comparison to the effect of simply building the manmade lake in the first place. Regardless of the temperature of the lake, much of it evaporates, whereas if we had not built the lake that water would have just made it to the ocean. Furthermore, the lake absorbs/reflects a different amount of light than the vegetation previously there. These energy flows dwarf the primary effects of human activity.Land use is seriously taken into account for the IPCC models. Urbanization decreases the amount of water the land holds, agriculture has a huge effect, and deforestation is probably the largest factor of all. But this does not bode well. Such activities usually decrease the ability of the Earth to cope with changes. For instance, you can't count on trees to suck up much CO2 if you just cut them all down.it's there in surface albedoBut we now get back to something else I was saying - the feedback loops. I was saying that direct human activities doesn't affect water vapor levels right? What affects it the most? What did we change that will affect water vapor levels? The answer:CO2, NH4, N2O, the usual suspectsThese have a small effect on the temperature of the Earth, namely increasing temperature (duh). That temperature change affects water vapor in the atmosphere - it increases it. In fact, it increases it FAR BEYOND ANY OTHER RECENT HUMAN OR NATURAL INFLUENCE.Any accusation that they did not take that into account in the relevant research is just wrong. That is exactly how they get alarmist claims beyond what direct radiative forcing gives. Also, the ice melting is another feedback loop, and together those make the two largest 'feedbacks' to the extent of my knowledge.So yeah, I don't understand these arguments that go; water vapor period.^^ it's not on the chart because it's a secondary effect. Does that sound reasonable?[Edited on June 24, 2008 at 2:48 PM. Reason : ]
