Simple question about global warming

Yes there's archeology which has deemed that there's no intelligent life located in the Chicago area for the last 100 years.[cheers]

LOL ... well played. [cheers]

Irrefutable means that it is impossible to disprove or deny. That means that something has actually happened. I'll give you that most scientists believe the earth experiences cooling periods every 40,000 years (approximately) due to the changing amount of the tilting of the earth's axis, however until that happens again, no one can say it's irrefutable. In fact, many scientists now wonder if it will happen or if it does, how much alteration will occur due to greenhouse gases.

Read the link. It is long, but it is a very good read. It references Milankovitch. It will also explain to Airport how we have longer records of temperature data than "150 years". I get a chuckle every time he says that. Someone else in this thread was making light of a rise in sea level of 2.5 inches. That is not a big deal, but if the trend continues, sea level will raise approximately one foot in one hundred years. That would be a big deal.

Using your logic that "until that happens, no one can say it is irrefutable" how can we then follow a logical progression that suggest that a 2.5" rise in water level over 20 years, plus or minus 1/5" each year will continue another 75 years. You can't argue on one hand that argument A is discarded until you see it happen while argument B could be a big deal even though you have not seen it happen.

I never said that the rise in sea level would continue at the same rate for the next 75 years. I did say, if it does, we have huge problems. "if the trend continues".

If the trend continues we are in a cyclical warming which will be followed by a cyclical cooling, since we are discussing trends. That is how logic works.
