Atmospheric Physics By Bruce

Bruce Thompson, host of Machias Privateer, has posted a fourth edition in his series Atmospheric Physics in which he chronicals the lunacy of the Global Warming Gang. I have reprinted it here with his permission.

Atmospheric Physics Part IV
The enormous amount of energy released in the earthquake and resultant tsunami off Sumatra dwarfs the efforts of Man. It truly raises the question, can Man really affect the environment in the face of the power of Nature? Are we capable of changing the climate through global warming? Let’s do some calculations.
One common unit of measure in these exalted realms is the kiloton equivalent of TNT (KT). This is given as 4,000,000,000,000 joules. Using the conversion factor of 1 British Thermal Unit (BTU) is equal to 1,055 joules, we come to the result that 1 KT = 3,790,000,000 BTUs.
Now let us consider a volume of air one mile on a side (i.e. 1 cubic mile). Using this calculator to figure the pressure at one mile (5280 feet) with a sea level pressure of 14.7 psi and a temperaure of 27 degrees C, we arrive at a pressure of 12.24 psi @ 5280 feet. So a column of air one mile high and one square inch in area horizontally weights 14.7 – 12.24 = 2.46 pounds. Multiplying by 144 square inches per square foot, then by 5280 times 5280 (feet/mile) we arrive at a total mass of 9,875,644,416 pounds for one cubic mile of air starting at sea level up.
The heat required to raise the temperature of that mass just one degree F, is equal to the mass times the specific heat (.24 BTU/pound – degree F). Doing the math we find that it takes about 2,370,000,000 BTUs to raise the temperature a single degree. That is 0.625 KT energy equivalent. I assume you all have seen the air temperature rise 20 degrees from morning to mid-afternoon. That would work out to be 12.5 KT or an amount equal to the atomic bomb at Hiroshima. Chicago has an area of 89 square miles. So heating just the lower mile of the atmosphere takes over 1 Megaton (MT) equivalent of energy. The Sun drops The Bomb on Chicago every summer day! Man is quite puny in the face of Nature, as was proven yesterday.

Bruce is as sharp as they come, and his blog is very inciteful and informative; he should be a daily read! To visit his site go here: Check out the other Atmospheric Physics post while you`re there. They go back in the archives to July. Well worth the time!

Hey, Tim -- hope you are feeling better -- you gotta get on the ball here and satisfy your hungering fans!! We are tapping our feet and waiting, now!!

No excuses -- we got Rathergate and Burglargate (or is that Soxgate?) and Clinton getting his fingers in the UN relief money pot and Hillary coming precious close to another juicy scandal. And as an antidote to all this evil -- we have God and religion and man to discuss.

Love the blog -- thanks for the comments on the religion thread -- hope you are back writing soon --
