Earth's magnetic field has weakened in time

Scientists recently discovered that A reversal in Earth's magnetic field thousands of years ago plunged the planet into an environmental crisis. It happened 42,000 years ago, according to the evolution timescale.

According to evolutionists, Our planet's magnetic field is dynamic and, numerous times, it has flipped — when the magnetic North and South Poles swap places. About once every 200,000 to 300,000 years, the field weakens enough to reverse polarity completely.

Earth's magnetosphere — the magnetic barrier surrounding the planet — originates from the churning of hot, molten metal around its iron core. This is an intelligent design feature and has nothing to do with evolution.

Researchers were looking for data for climate change. They look into changes in levels of carbon 14, a radioactive form of the element bog-and preserved kauri trees (Agathis australis) from northern New Zealand and thought these were caused by. brief polarity reversal called the Laschamps Excursion, which took place between 41,000 and 42,000 years ago and thought the megafauna in Australia began to go extinct and Neanderthals in Europe were dying out at that time.  Scientists recently discovered that A reversal in Earth's magnetic field thousands of years ago plunged the planet into an environmental crisis.
