"which condition is the norm, the 4595 year one or the 50 year one, or the warmer one which ended 5000 years ago?" I don't think that 5,000 years (a mere 'blink' of time in geological or climatological terms) is near long enough to identify a 'normal' temp. But, I suppose that 500,000 years might be enough to answer such questions as: 1) RANGE --- what is the 'normal' range for temp.? 2) Average - MEAN --- what is the arithmetic temperature average for that 1/2 million year time span? 3) Average - MODE & NODE. And, to perhaps answer the question of equal importance --- what is the 'normal' VOLATILITY in the temps.? Now, if there are LONGER CYCLES then can be expressed in 1/2 million years of data... then that caviat would still remain an important consideration. --------------------------------------------- Joke starts here.... --------------------------------------------- But, true fact, the US National Weather Service has officially defined a 'normal' day for the US... Believe (if memory serves me...) it is something like 70 degrees F., 50% cloud cover, and 80% relative humidity --- (but I could be misremembering some of that.... :-)
