Don’t look now, it’s a climate disaster of massive proportions and it has nothing to do with CO2.
Scientists have just discovered a wild era 42,000 years ago — where the Earth’s magnetic field practically disappeared. They’ve called it the Adams Event (after Douglas Adams of Hitchhikers Guide fame).
This was hidden previously, just before the Laschamp Excursion which we’ve known about since 1969. That event happened about 41,000 years ago – during which the Earth’s magnetic field briefly flipped. It was a pretty big deal in itself. For 800 years the field strength fell to 28% of it’s current strength and was reversed North-to-south. Due to the weak magnetic field, cosmic rays zinged further into the atmosphere and created a layer of enriched beryllium 10 and carbon 14 which remains to this day in a thin slice around the world buried under all the layers of dirt that came after it.
Extraordinarily, during all this, one giant Kauri tree managed to live for more than 1,700 years. It lived and died in New Zealand, and people got […]
