Refutation of Young-Earth Geomagnetic Models

TNRTB Archive - Retained for reference information

A team of Swiss and American paleoclimatologists and particle physicists have developed a powerful refutation of young-earth creationist models for the past history of Earth’s magnetic field. The higher the intensity of Earth’s magnetic field, the stronger the deflection of primary cosmic rays and, consequently, the fewer cosmogenic radionuclides that are produced. Using measures of the cosmogenic radionuclides beryllium-10, chlorine-36, and carbon-14 determined from the GRIP Greenland ice core, the team established that the intensity of Earth’s magnetic field reached maxima at 2,000, 8,500, 22,000, 30,000, and 48,000 years ago. Their results show that over the past 35,000 years Earth’s magnetic field intensity has stayed within the range of one-half to twice its present value. Such results refute young-earth creationist claims that the presently precipitous decay of Earth’s magnetic field strength proves that Earth must be younger than 20,000 years or that Earth’s magnetic field intensity experienced dramatic oscillations during the flood of Noah.
