Approximately 41 000 years ago, Earth’s magnetic field reversed during the Laschamp event. This caused the magnetic field to weaken to just 5% of its current strength, allowing more cosmic rays to reach the planet’s surface.
A new study published in the Russian Journal of Pacific Geology looks into geomagnetic excursions over the last 10 000 years utilizing peat deposits from Russia’s Khabarovsk Territory. The study called into attention the importance of understanding these transitory shifts in Earth’s magnetic poles, which differ from total geomagnetic reversals and impact climatic and environmental circumstances.
