real life saysQuote: The figures quoted, if correct and you seem to concede that they may be, would seem to indicate not just a decay of the dipole, but an overall loss when measuring the total energy of the magnetic field, would it not?
.
As usual you get things sort of half right before you go and try to underpinn russ Humphreys. If we even lose 50% of our dipole strength we would still be about 25% greater Magnetic field strength than in the previous Gauss and Gilbert normal and reverse periods. your quoting some data that shows a decline of field strength comprised mostly of dipole field that was already at an extreme high before the Brunhes normal (last 700000years0 so that makes the last 100 years data less than 0.015 % of the entire data period from the start of the Brunhes till today.
The point that youre seemingly impresseed with is that (making an analogy from a thermometer) "in the summer the average temperature may be 75F with excur sions into the 90's, t
hen when winter arrives
the average temperature is 32 degrees with similar excursions. Imagine that we came off a period with extra high summer highs and now are getting back to a "normal" range. Thats what the data shows.
IT HAS NO CREDIBILITY IN PROVIDING DATA TO PROVE THAT THE EARTH IS ONLY 6000 YEARS OLD. Thats Humphreys point, all of it . Hes all wet
The fact that the pole is wandering is another way to evidence the probaility that the earths magnetic poles will reverse in the future. We have no idea when, since from past remanent magnetostratigraphic data, polar reversals have lasted from about 80 million years to as little as 20000 yrs, and since there is no appARENT periodicity remanent magnetism makes a great tool to establish a magnetic based clock.
I still would like you to find a copy of Merrilll,RT, McElhinny,MW, and McFadden,PL 1998. "The Magnetic Field Of the Earth" APIG series63.
Then perhaps your random quotes wont sound as panicky
Since Humphreys pretty much stands alone (along with the originator of the ruse , Dr Barnes) I dont feel much disposed to discredit pieces of work that not only defy credible science but have no reasonable alternative mechanism to explain the earths magnetic field at all.Yet you ask me to accept USGS data as if the mere acceptance of same adds credibility to Humphreys case that the Earth is younger than 10000 years. My momma raised no foolThere is field data available on the dipole strength and one can calculTE THE DIRECTIONS AND STRENGTH OF DIPOLE INCLINATION AND DECLINATION THROUGH prehistory. We can also accurately estimate the higher harmonics and we certainly have cross correlated the magnetochronometry with stratigraphy, thermoluminescence, radioisotopes and the fossil record.Humphrey pretty much stands alone on a hill (or in a ditch depending on where your level of understanding is derived).
