Refer back to even Regenmacher's link to realclimate.org and you will see they profess as well, that same amount...so please, dont YOU confuse
effect with substance.
You are the one confusing effect with substance. Go back and reread my post. I said:
"CO2 makes up more like about 90% at least of greenhouse . Co2 levels are about .05% of the earth's atmosphere, not greenhouse gases, big
Even the source you quoted gives much different numbers than you say, your source directly contradicts you, however, the information in the Wikipedia
article is just plain wrong. Anyone can submit "information" to Wikipedia, and they do. Water vapor in fact, helps to regulate and keep the balance
of earth's atmosphere. This is what it's all about, is that the earth's natural regulating sources have been messed with by our human activity.
Things are out of balance, so that Earth has trouble getting that back until we humans quit messing with her. If you keep feeding your Mother poison
everyday, eventually it accumulates and She dies.
The sources that are saying that water vapor is the biggest cause of GW are just plain wrong. Water vapor is the most abundant greenhouse gas in the
atmosphere, not not the primary cause of the greenhouse effect because water vapor coalesces into clouds, which reflect radiant energy. When quoting
science, it's important to get it from credible sources, not corporate propaganda, of which there is much out there. Here is an article from the NOAA
website. NOAA is a government website and one of the best places to get scientific data and info from. NASA would be another one that is good, but not
quite as good as NOAA, but these 2 agencies are both excellent resources. There is alot of junk science out there on the internet.
This new "theory" circulating around the internet saying that water vapor is the biggest culprit regarding greenhouse gases is just plain wrong.
Someone misinterpreted the info or deliberately did it to confuse people but it's completely wrong, that's not how water vapor works. Water is a
regulator, not a contributor to GW effects. Deforestation and descrution of ocean ecology are major contributors because only green plants convert CO2
into oxygen (and sequester carbon).
I got my science information from an award-winning biologist who was in Who's Who 7 times and won awards for teaching biology and global warming,
which he did for 20 years at the nation's top public school.
Quote from website:
"Water Vapor is the most abundant greenhouse gas in the atmosphere, which is why it is addressed here first. However, changes in its conentration is
also considered to be a result of climate feedbacks related to the warming of the atmosphere rather than a direct result of industrialization. The
feedback loop in which water is involved is critically important to projecting future climate change, but as yet is still fairly poorly measured and
As the temperature of the atmosphere rises, more water is evaporated from ground storage (rivers, oceans, reservoirs, soil). Because the air is
warmer, the relative humidity can be higher (in essence, the air is able to 'hold' more water when its warmer), leading to more water vapor in the
atmosphere. As a greenhouse gas, the higher concentration of water vapor is then able to absorb more thermal IR energy radiated from the Earth, thus
further warming the atmosphere. The warmer atmosphere can then hold more water vapor and so on and so on. This is referred to as a 'positive feedback
loop'. However, huge scientific uncertainty exists in defining the extent and importance of this feedback loop. As water vapor increases in the
atmosphere, more of it will eventually also condense into clouds, which are more able to reflect incoming solar radiation (thus allowing less energy
to reach the Earth's surface and heat it up). The future monitoring of atmospheric processes involving water vapor will be critical to fully
understand the feedbacks in the climate system leading to global climate change. As yet, though the basics of the hydrological cycle are fairly well
understood, we have very little comprehension of the complexity of the feedback loops. Also, while we have good atmospheric measurements of other key
greenhouse gases such as carbon dioxide and methane, we have poor measurements of global water vapor, so it is not certain by how much atmospheric
concentrations have risen in recent decades or centuries, though satellite measurements, combined with balloon data and some in-situ ground
measurements indicate generally positive trends in global water vapor."
