Water vapor is responsible for up to 70% of the greenhouse gases!!! Whoduh thunk?

Again science points to the dangers of dihydrogen monoxide.

[henkster]

The IPieceofCCr@p, Al Gore and the egghead priest/prostitute scientists all refuse to recognize the following facts:

1. 100,000-40,000 years ago, mile-thick ice sheets covered much of the Northern Hemisphere
2. 20,000-40,000 years ago a warming period began, which melted these ice sheets.
3. During the period of about 1000-1400 A.D., the Medieval Warm Period allowed for prolonged human settlement of Greenland, which is still not feasible today due to the cold climatic conditions.
4. About 1300-1400 the earth entered what is know as “The Little Ice Age,” from which it is still emerging.
5. The above worthies cannot properly identify the causes of all of the above, and thus cannot state that those causes are not the predominant movers of climate change today.

Those are just my 5 fun historical facts to trot out whenever confronted by the “True Believers.”

Doug:

A really great post.

An observation - too many scientists live and work in an information bubble that provides a feedback loop of self-reinforcing thinking, while much of what could be learned and observed, outside that bubble, is ignored.

“Incomplete” is the outstanding accomplishment of the scientific thinking that emerges from these bubbles - like the bubble the man-made global warming advocates in “science” live and breath under.

[Reeses]

Global warmers hate to discuss clouds and snow because these act as giant natural mirrors bouncing sun heat back out to space. They especially don’t want to talk about man-made clouds and snow and the role of wind blown sand, dirt, and pollution which increase their formation. GWers are afraid to even research and model clouds because then the Luddite party would be over.

Ida thunk it to be higher - still do

I like to have really humid air in my greenhouse during the winter. It holds the heat better.

Ping to Curiosity,

Note, per our previous thread, that there is still very credible and objectionable scientific data and research that challenges the impact of Man Made CO2.

If you would like to debate these finer issues, then there is real progress being made. But as I said, Labeling us as “GW deniers” for citing debatable science behind the causes of global warming proves that the current alarmists propaganda has crossed the line from scientific in nature to religious. When science is thrown out and debate is stifled, then one can only rely on faith. I, therefore, question your “faith” in Man Made Global Warming.

(Note: I am not turning this into religious discussion as I am a devout Catholic. But use theses “radical” words to emphasize a point.)

The most important players on the greenhouse stage are water vapor and clouds. Carbon dioxide has been increased to about 0.038% of the atmosphere (possibly from about 0.028% pre-Industrial Revolution) while water in its various forms ranges from 0% to 4% of the atmosphere and its properties vary by what form it is in and even at what altitude it is found in the atmosphere. In simple terms, however, the bulk of Earth's greenhouse effect is due to water vapor by virtue of its abundance. Water accounts for about 90% of the Earth's greenhouse effect -- perhaps 70% is due to water vapor and about 20% due to clouds (mostly water droplets), some estimates put water as high as 95% of Earth's total greenhouse effect. The remaining portion comes from carbon dioxide, nitrous oxide, methane, ozone and miscellaneous other "minor greenhouse gases." As an example of the relative importance of water it should be noted that changes in the relative humidity on the order of 1.3-4% are equivalent to the effect of doubling CO2.

Global warming theory depends on this feedback from increased water vapour. In essence, the physics says that increased CO2 will provide a slight increase in temperatures. A slightly warmer atmosphere can then hold more water vapour and hence you get even more warming.

Without the increased water vapour feedback, increased CO2 would only increase temperatures by about 1.0C for every doubling of CO2 or about 1.0C of warming by the year 2,100. That is nothing really to worry about at all. Natural variability of the climate is even greater than this.

So, global warming is a dud (theory alone) without the water vapour feedback.

What does the evidence show?

- Water vapour has increased slightly in the last 50 years (nowhere near the level global warming theory predicts); and,
- the historical climate evidence shows that water vapour is probably a stablizing factor in the climate (rather than a runaway positive feedback) It gets warmer, more water vapour goes into the atmosphere, we get more rain and more clouds reducing the temperature and stabilizing the climate. The planet has been here for 4.5 Billion years and it seems the climate has usually been around today’s temperature give or take about 6.0C. All those oceans and all that water keeps Earth at a nice temp.
