I created this thread here simply because greater control is necessary to debate this critical issue. One of the main problems, which causes the debate to cease, is the use of generic terms which include subsets of other items which may or may not be root causes.
Lets take the Term "Global Warming". The term insinuates that the earth is warming but what it does not do is determine what the individual or cumulative causes are for it. For the purposes of this thread this term is not acceptable as it fails to identify whether the cause in warming is attributed to man or attributed to natural process.
As you can see the choice of terms is ambiguous and leaves open the problems of misinterpretation or outright deceitful misdirection.
Natural Variation = Processes which are natural and occur without mans influence.
Natural Forcing = Specific definable processes which triggers warming or cooling.
Man Created Forcing = The specific contribution which results in warming or cooling. (Also known as Anthropogenic Forcing) and may enhance/mute natural ones
Land Use Induced = Changes in local areas which are due to the lands use. (roads, buildings, etc which result in the Urban Heat Island or other potential changes from the natural state of the area)
Pollution = Man created products which cause harm to the natural environment. Naturally occurring gasses and those items which occur through the natural cycles of the earth are not considered pollutants. (CO2 can be both but be prepared to show how you determined what was naturally caused and what is man created.) [Negative impacts on health do not occur below 6,000ppm - United States Navy determination on long term submarine operations].
Consensus = Is not a scientific term and alludes to the possibility that there is no other meaning, process or reason for what we observe. It is inherently anti-science and political (mob rule).
With the majority of the troublesome terms well defined lets try this one again..
The IPCC makes the claim that all of the warming post 1950 is man caused due to the increase of CO2 in our atmosphere. So lets see just what the natural process was prior to 1950 and compare it to that time span.
Lets define the most recent natural rate of warming which I will do in my next post and then we will try to hash this out..
