Researchers find oldest undisputed evidence of Earth’s magnetic field

Quote

A new study, led by the University of Oxford and MIT, has recovered a 3.7-billion-year-old record of Earth’s magnetic field, and found that it appears remarkably similar to the field surrounding Earth today. The findings have been published today in the Journal of Geophysical Research.

Without its magnetic field, life on Earth would not be possible since this shields us from harmful cosmic radiation and charged particles emitted by the Sun (the ‘solar wind’). But up to now, there has been no reliable date for when the modern magnetic field was first established.

Eh, I don't like the pseudo-baked contact tests and I'm distrustful of the CRM to paleointensity. 

It's laughable that the researchers think a direction is "defined" with an a95 of 51 degrees.

A lot of interpretation of noise here.
