Yep....I've watched in here for many years....
25,000 USMB members....about 5, maybe 6 take Crick seriously. We know who they are too!!
I have always found it fascinating that an ENVIRONMENT forum is dominated by climate skeptics.

The IPCC, in its assessment report, will explain to you very clearly how those uncertainties are calculated and how their entire process works. It is a paragon of transparency. Of course, if you never read it because it might refute your preconceived notions or the the points that your political heroes have made to you, you'll never know. So, before you take the word of Mr Corbett, maybe you ought to look FOR YOURSELF.Episode 282 - The IPCC Exposed
Corbett • 09/28/2013
"The IPCC has released its latest assessment of the state of climate science, and this time it's even more dire than their 2007 assessment. Global warming is "unequivocal" and humans are the "dominant cause" to a certainty of 95%. But how are these uncertainties calculated? And how does the IPCC process work anyway?Episode 282 – The IPCC Exposed | The Corbett Report

You. Gaia is one of the gods of your wacky religion. I think she more commonly goes by 'Climate' nowadays...
Random number, even outside of the fraud used to come up with it.
But it is one being significantly altered by human activities, hitting levels never seen by homo sapiens and not seen on Earth for well over a million years. Water vapor, being a precipitable component, will not be directly increased by human activity.
Volume proportion is not what determines the amount of energy trapped by a greenhouse gas. Water vapor retains more IR than does CO2 but it is not changing. The warming of the planet is being caused by human activity increasing the level of atmsopheric CO2 a gas with a lifetime measured in centuries. What water vapor, with a lifetime measured in days, does, is basically irrelevant. It is not responsible for the observed warming. It will not ameliorate the observed warming.
Methane is exceedingly potent as a greenhouse gas. Fortunately, its lifetime is only about 12 years and it is at much lower levels than CO2. Look at the table below and compare the proportion of greenhouse warming of each gas to their absolute levels in the atmosphere. Do you not see that arguments that try to tell you that CO2 and methane can't hurt us because their levels are so small are just bullshit attempting to take advantage of the general science ignorance of the audience they're targeting?
All of these gases are being created and emitted by human activities• Figure 1 from ABC news shows the false information. It’s achieved by considering a dry atmosphere.

This comment that that the range of a parameter makes the information useless has become a very popular denier meme. The truth is, it makes it obvious that the IPCC is being honest and accurate while you and Tim Ball and WUWT are not. Here is a larger excerpt from the Wikipedia article on "Greenhouse gas"• The percentages troubled the IPCC so they amplified the importance of CO2 by estimating the “contribution” per unit (Figure 2). The range of estimates effectively makes the measures meaningless, unless you have a political agenda. Wikipedia acknowledges “It is not possible to state that a certain gas causes an exact percentage of the greenhouse effect.”

No. It's meant to be people like you who are scared of natural climate fluctuations of which the geologic record is littered with.

Bwahahahahahahahahahaha!!!From Wikipedia's article on Dr Ball
Timothy Francis Ball (November 5, 1938 – September 24, 2022) was a British-born Canadian public speaker and writer who was a professor in the Department of Geography at the University of Winnipeg from 1971 until his retirement in 1996. Ball then became very active in promoting rejection of the scientific consensus on global warming, giving public talks and writing opinion pieces and letters to the editor for Canadian newspapers. He has been a member of energy industry funded lobbying groups.
Ball's expertise in chemistry and physics is ZERO. Ball is funded by the energy industry and has been for years. -- OP
Maurice Frederick Strong, PC, CC, OM, FRSC, FRAIC (April 29, 1929 – November 27, 2015) was a Canadian oil and mineral businessman and a diplomat who served as Under-Secretary-General of the United Nations.[4][5][6]
Strong had his start as an entrepreneur in the Alberta oil patch and was President of Power Corporation of Canada until 1966. In the early 1970s he was Secretary General of the United Nations Conference on the Human Environment and then became the first executive director of the United Nations Environment Programme. He returned to Canada to become Chief Executive Officer of Petro-Canada from 1976 to 1978. He headed Ontario Hydro, one of North America's largest power utilities, was national president and chairman of the Extension Committee of the World Alliance of YMCAs, and headed American Water Development Incorporated. He served as a commissioner of the World Commission on Environment and Development in 1986[7] and was recognised by the International Union for Conservation of Nature as a leader in the international environmental movement.[8]
He was President of the Council of the University for Peace from 1998 to 2006. More recently Strong was an active honorary professor at Peking University and honorary chairman of its Environmental Foundation. He was chairman of the advisory board for the Institute for Research on Security and Sustainability for Northeast Asia.[9] He died at the age of 86 in 2015.[10]

SIDELIGHTS:
Elaine Dewar is a Canadian investigative journalist and nonfiction science writer. In Cloak of Green, she presents a study of the environmental movement in various places around the world. She states in her book that, like many other organizations, the environmental movement is connected to government agencies and businesses, and it works to promote and protect its own interests. Dewar also theorizes that environmental groups are linked in a conspiratorial effort to destroy nationalism and create a new world order, which the author calls the "Global Governance Agenda."

This comment that that the range of a parameter makes the information useless has become a very popular denier meme. The truth is, it makes it obvious that the IPCC is being honest and accurate while you and Tim Ball and WUWT are not. Here is a larger excerpt from the Wikipedia article on "Greenhouse gas"
Impacts on the overall greenhouse effect
Main article: Greenhouse effect
Schmidt et al. (2010)[28] analyzed how individual components of the atmosphere contribute to the total greenhouse effect. They estimated that water vapor accounts for about 50% of Earth's greenhouse effect, with clouds contributing 25%, carbon dioxide 20%, and the minor greenhouse gases and aerosols accounting for the remaining 5%. In the study, the reference model atmosphere is for 1980 conditions. Image credit: NASA.[29]
The contribution of each gas to the greenhouse effect is determined by the characteristics of that gas, its abundance, and any indirect effects it may cause. For example, the direct radiative effect of a mass of methane is about 84 times stronger than the same mass of carbon dioxide over a 20-year time frame[30] but it is present in much smaller concentrations so that its total direct radiative effect has so far been smaller, in part due to its shorter atmospheric lifetime in the absence of additional carbon sequestration. On the other hand, in addition to its direct radiative impact, methane has a large, indirect radiative effect because it contributes to ozone formation. Shindell et al. (2005)[31] argues that the contribution to climate change from methane is at least double previous estimates as a result of this effect.[32]
When ranked by their direct contribution to the greenhouse effect, the most important are:[27]
In addition to the main greenhouse gases listed above, other greenhouse gases include sulfur hexafluoride, hydrofluorocarbons and perfluorocarbons (see IPCC list of greenhouse gases). Some greenhouse gases are not often listed. For example, nitrogen trifluoride has a high global warming potential (GWP) but is only present in very small quantities.[35]

Referred to by: Blasing (2013). Based on Blasing (2013): Pre-1750 concentrations of CH4,N2O and current concentrations of O3, are taken from Table 4.1 (a) of the IPCC Intergovernmental Panel on Climate Change, 2001. Following the convention of IPCC (2001), inferred global-scale trace-gas concentrations from prior to 1750 are assumed to be practically uninfluenced by human activities such as increasingly specialized agriculture, land clearing, and combustion of fossil fuels. Preindustrial concentrations of industrially manufactured compounds are given as zero. The short atmospheric lifetime of ozone (hours-days) together with the spatial variability of its sources precludes a globally or vertically homogeneous distribution, so that a fractional unit such as parts per billion would not apply over a range of altitudes or geographical locations. Therefore a different unit is used to integrate the varying concentrations of ozone in the vertical dimension over a unit area, and the results can then be averaged globally. This unit is called a Dobson Unit (D.U.), after G.M.B. Dobson, one of the first investigators of atmospheric ozone. A Dobson unit is the amount of ozone in a column that, unmixed with the rest of the atmosphere, would be 10 micrometers thick at standard temperature and pressure.

CO2 averages for year 2012 are taken from the National Oceanic and Atmospheric Administration, Earth System Research Laboratory, web site: www.esrl.noaa.gov/gmd/ccgg/trends maintained by Dr. Pieter Tans.
