An inconvenient truth.... or lie?

Hi Buzsaw,So in five pages I see that only one scientist, Coyote, has posted.And he agrees with you that man make global warming is probably a crock.I've been a petroleum exploration geologist for the last 35 years. I make a living looking for unknown and undiscovered oil and gas deposits.That job requires me to know the paleoenvironments and climates of various areas from the Cambrian to now.For 90% of the time from the Cambrian to now the average earth's temperature was about 72 degrees F, it is presently 58 degrees F.The only other time from the Cambrian to now that the temperature and CO2 content was as low as it is today was during the glacial and interglacial periods of the Pennsylvanian and Permian.Coyote mentioned the warm period during the Middle Ages, but there have been many times where the temperatures have been much higher along with much much higher CO2 concentrations then we see today.They were not caused by man as he wasn't there.So now Buzsaw, you have two scientists on your side and none against.
