Not sure about your point regarding water vapor. There are many constituents keeping global climate relatively stable. The amount of water vapor is a big one. But people don't have much of an effect on water vapor content in the atmosphere.
Water vapor is the NUMBER one greenhouse gas.
The computer models in use can not handle it at all.
Latest issue of Infinite Energy Magazine : Global Warming, Fact or Fiction : by William H. Cantrell, Phd : Climate Change and Clearing the Air : test questions : 1)The last ice age was known as "the Little Ice Age"and it occurred a)during the 17th and the 19th centuries b)10,000 yrs ago c)100,000 yrs ago d)over 1,000,000 yrs ago e)during the carter administration....2)During the past 3,000 yrs the earth's climate has at times been much WARMER than it is today a)true b)false...3)Based on Carbon 14 dating during the past 7,000 yrs, how many times has the earth's climate been much COLDER than it is today? a)10 times b)twice c)once....4)During the last 20 yrs with the highest recorded levels of atmospheric CO2, temperatures have a)decreased b)remained the same c)increased....5)As CO2 levels increase, overall plant growth rates will a)easily double b)decline slightly c)decrease significantly, indicating a positive feedback spiral....6)The continental US is a a)net sink for carbon emissions b)huge source of carbon emissions...7)Standing timber in the US a)has increased by more than 30% since 1950 b)has decreased to less than 30% of 1950 levels )is expected to decline to 2% by the end of the 21st century......and on up to #14)While the economy has increased dramatically, concentrations of major air pollutants in the Western World have a)decreased dramatically b)leveled off c)increased dramatically.....All answers are a) of course...his point : water and water vapor is the main driver of global climate, not CO2. Atmospheric science is a very complex subject but again, what's so BAD about the arctic warming up? What's so BAD about climate changes here and there? This fundamental assumption that the climate is supposed to be static is NONSENSE, it's always been a'changing, always will, roll with the punches, it's called EVOLUTION.
