Zoë Thomas on the 'Adams Event'

42,000 years ago the temporary breakdown of Earth’s magnetic field sparked major climate shifts that led to global environmental change and mass extinctions. This dramatic turning point in Earth’s history – laced with electrical storms, widespread auroras, and cosmic radiation – was triggered by the reversal of Earth’s magnetic poles and changing solar winds. Zoë Thomas was part of the research team that made this discovery which was published in 2021. In this podcast, hear how this incredible discovery was made, exactly what occurred 42,000 years ago and the impact this has had on life on Earth.
