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,

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."
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
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]
notes:
(A) Water vapor strongly varies locally[34]
(B) The concentration in stratosphere. About 90% of the ozone in Earth's atmosphere is contained in the stratosphere. | | | |
---|
Compound | Formula | Concentration in
atmosphere[33] (ppm) | Contribution
(%) |
---|
Water vapor and clouds | H
2O | 10–50,000(A) | 36–72% |
Carbon dioxide | CO2 | ~400 | 9–26% |
Methane | CH
4 | ~1.8 | 4–9% |
Ozone | O
3 | 2–8(B) | 3–7% |
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.

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.
- ^ Because atmospheric concentrations of most gases tend to vary systematically over the course of a year, figures given represent averages over a 12-month period for all gases except ozone (O3), for which a current global value has been estimated (IPCC, 2001, Table 4.1a). 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.
