The Church of Al Gore/IPCC claims man is driving the world climate through CO2 production. Some people buy that simply because no one ever illustrates the foolishness of this claim. So let’s do some comparisons using the all the water on planet Earth to represent the Green House engine, and let’s show how relatively small the man-made component is when we look at the entire engine. We will find that the contribution of man-made CO2 is, literally, a drop in the ocean.

So with all the water on Earth representing the Green House Gas engine let’s do some math. Let’s begin here with what we know:

This is an amazing feat when you consider that human-added concentrations of CO2 are only about five per cent of natural carbon emissions every year from factors like rotting vegetation, volcanoes, outgassing from the oceans, and the like. And amazing considering that 90 to 95 per cent of the greenhouse effect is produced by water vapor, not CO2.

Never mind. For the Hadley Centre, five per cent of a trace gas like carbon dioxide (CO2 is only 380 parts per million in the atmosphere, to which human emissions add about 10 ppm every five years) is “driving” the greenhouse gas system.

Emphasis mine. If all the water on Earth represents the Green House Gas effect, and 95% of that effect is the from water. Of the remaining 5%, man-made CO2 is only 5% of that number. Which means if we add up all the “non man-made” 95% + 4.75% = 99.75% of the Green House Engine is not due to man.

So, let’s compare 99.75% to the volume of water in the world’s oceans. From this site we learn:

	Volume in Thousands of Cubic Kilometers	Percentage of Total Water on Earth	Remarks
Oceans	1,310,302	97.3	This is salty sea water.Â
Ice	29,492	2.2	Much of this ice is in the Antarctic
Groundwater	6,733	0.5	Underground aquifers, deep wells
Lakes	242	0.02	Provide drinking water, irrigation water, fish and recreation
 Soil Moisture	74	0.005	This is being used by our crops, trees, and surface vegetation
 Water Vapor in the Atmosphere	14	0.001	 Clouds, fog, and dew
 Rivers	1.3	0.0001	Provide water for drinking, irrigation, and recreation

So, let’s role up the amount of water on Earth we need to represent the non man-made Green House gas elements. Let’s start with the worlds oceans, which gives us 97.3%. If we add in the water trapped in the world’s ice we jump to 99.5%. If we add in all the lakes we get to 99.52%. If we add in all the world’s rivers we get 99.5201%.

So, if we were to use this example where all the water in the oceans, the ice caps, the rivers and the lakes represents the non man-made factors in the Green House effect, then the man-made component from CO2 is literally a drop in the ocean. Does anyone believe the average temperature of the oceans, ice caps, rivers and lakes could be changed by 5% of the remaining water? Of course not.

Some historical perspective from the first link above:

Furthermore, in the 1850s the planet came out of more than 400 years of cooling known as the Little Ice Age. Before that, during the Medieval Warm Period (900-1350), global temperatures were a degree or two Celsius higher than today’s. Temperatures were warmer about 2,000 years ago (the Roman Warm Period) and about 3,500 years ago (the Minoan Warm Period).

…

This means that over the past 5,000 years there’s been a major warming and cooling cycle every 1,000 years or so. The current warming, a millennium after the Medieval Warm Period, is right on track as part of that natural cycle.

Seems obvious to me it is highly implausible .25% can drive 99.75%, yet highly plausible we are in a natural cycle of warming we have seen in the historic record.
