The House of Commons' Science and Technology Committee said they had seen no evidence to support charges that the University of East Anglia's Climatic Research Unit or its director, Phil Jones, had tampered with data or perverted the peer review process to exaggerate the threat of global warming two of the most serious criticisms levied against the climatologist and his colleagues.
Gaseous water represents a small but environmentally significant constituent of the atmosphere. Approximately 99.13% of it is contained in the troposphere. The condensation of water vapor to the liquid or ice phase is responsible for clouds, rain, snow, and other precipitation, all of which count among the most significant elements of what we experience as weather. Less obviously, the latent heat of vaporization, which is released to the atmosphere whenever condensation occurs, is one of the most important terms in the atmospheric energy budget on both local and global scales. For example, latent heat release in atmospheric convection is directly responsible for powering destructive storms such as tropical cyclones and severe thunderstorms. Water vapor is also the most potent greenhouse gas owing to the presence of the hydroxyl bond which absorbs strongly in the infra-red region of the light spectrum. Because the water vapor content of the atmosphere will increase in response to warmer temperatures, there is a water vapor feedback is expected to amplify the climate warming effect due to increased carbon dioxide alone. It is less clear how cloudiness would respond to a warming climate; depending on the nature of the response, clouds could either further amplify or partly mitigate warming from long-lived greenhouse gases.
Fog and clouds form through condensation around cloud condensation nuclei. In the absence of nuclei, condensation will only occur at much lower temperatures. Under persistent condensation or deposition, cloud droplets or snowflakes form, which precipitate when they reach a critical mass.

The average residence time of water molecules in the troposphere is about 10 days. Water depleted by precipitation is replenished by evaporation from the seas, lakes, rivers and the transpiration of plants, and other biological and geological processes.
Atmospheric water vapor content is expressed using various measures. These include vapor pressure, specific humidity, mixing ratio, dew point temperature, and relative humidity. The annual mean global concentration of water vapor would yield about 25 mm of liquid water over the entire surface of the Earth if it were to instantly fall as rain. The mean annual precipitation for the planet is about 1 meter, which indicates a rapid turnover of water in the air - on average, the residence time of a water vapor molecule in the atmosphere is about 9 to 10 days.
The abundance of gases emitted by volcanoes varies considerably from volcano to volcano. However, water vapor is consistently the most common volcanic gas, normally comprising more than 60% of total emissions during a subaerial eruption.
I should also here quote the late, great Carl Sagan: "Extraordinary claims require extraordinary evidence."
"Hide the decline" was not an attempt to conceal data but was scientific shorthand for discarding erroneous data."
So discarding data is now science is it? Nope we weren't concealing it, we were just discarding it! Even worse.
Except that there's nothing extraordinary about the claim that dumping tons and tons of CO2 into the atmosphere will cause the planet to get hotter. Carl Sagan would be the first to say that that's common fucking sense.

Volcanoes emit CO2 also, we should start taxing Earth.
This seems like a huge amount of CO2, but a visit to the U.S. Department of Energy's Carbon Dioxide Information Analysis Center (CDIAC) website (http://cdiac.ornl.gov/) helps anyone armed with a handheld calculator and a high school chemistry text put the volcanic CO2 tally into perspective. Because while 200 million tonnes of CO2 is large, the global fossil fuel CO2 emissions for 2003 tipped the scales at 26.8 billion tonnes. Thus, not only does volcanic CO2 not dwarf that of human activity, it actually comprises less than 1 percent of that value.
MSNBC, fair and balanced.
Since they where so bold to leave out the influence of the sun and cosmic rays, and the influence of water vapour i do not trust them fully. ...
.... i have always wondered what the spectral absorption and reflection is of carbon dioxide. Does anybody know ?
Given the number of Foxnews and UK Daily Mail articles that has been linked here by skeptics, this objection is really a hoot.

"colloquial terms"...that's certainly an interesting way to say intentionally mislead. Seriously...what utter bullshit.
Yeah....it was really investigated...this is just more coverup

What happened is obvious...Jones and company intentionally left out all 'inconvenient' post-1960 tree ring proxy data. "Hide the decline" meant exactly that...."colloquial terms" my ass. Total bullshit.lol. DSF in unconviced. I'm unsurprised
Yeah, just like that 9/11 conspiracy, moon landings and JFK. It's all just a massive conspiracy. We're lucky to have rational skeptics like yourself to save us from all those hateful, deceitful scientists.
If you knew anything about statistics you would know that data is excluded all the time, normally at the very top and the very bottom to varying degrees depending on the model and what you're looking at.
But please continue blathering, your feelings do count for something.
Oh, it's that simple? Care to explain then why the rise and fall of global temperatures don't line up exactly with the rise of CO2 output?
