See CO2?

Thanks to Eric at Classical Values I have come across some very interesting numbers about CO2.

Let us start at the beginning. Before the advent of fuel burning industry the concentration of CO2 in the atmosphere was 288 parts per million (ppm). By the year 2000 man had added 11.88 ppm to that total and nature has added 68.52 ppm to the total. Which means that if the effect is linear (it is not for reasons I won't go into here) and man has added about 15% of the CO2 that has been added to the atmosphere and the temperature rise has been about 1.1 deg F (.6 deg C). Then man made CO2 has been responsible for at most about .15 deg F (.1 deg C) of climate change. Which fits in well with Nir Shaviv's analysis, which says that solar variations accounts for .9 deg F (.5 deg C) of global warming.

That is the best case for the global warming guys. Because parts of the argument are wrong. It assumes that the whole of the warming is caused by CO2. For the sake of argument let us say that the solar contribution is 80%. That would mean that the increase in CO2 is responsible for about .22 deg F (.1 deg C) of the global warming. Man's contribution would then be 15% of that or about .033 deg F or (.015 deg C).

I wonder if any one has told Al Gore?

That is very interesting, and to add on to that point I was informed recently that the amount of man made C02 in the atmosphere is, 3 %. I love how you put a hypothetical twist in regards to to 80% example, well put! Perhaps all of Al Gore's litle minions should do their homework before slapping their hands together in excitement over a man who preaches utter nonsese. I suppose it doesn't take a great deal of brainpower to be obseqious to a contierfiet phoney, but Al Gore...man alive.

Perhaps some should start praciticing the magic of sight and hearing, or atleased being able to decipher the difference between real and make-believe..maybe they may stray away from their fears of polar bears being stranded on large blocks of ice, go out and rent a disney movies, and sleep soundly at night.

Thank you for using real facts.
I believe that wanton pollution of any kind is wrong, but this hysterical promotion of man made carbon dioxide being the root cause of global warming is either for political gain or lobbying for government funds. ( also political) Their own argument of cause and effect clearly shows that the effect, global warming precedes the cause increased carbon dioxide in the atmosphere by many years.

What about methane?

Did Al Gore mention methane?

In any case I will leave the fight against cows to some one else. Eric has that covered.
