Earth magnetic field weakening 2022
WebAug 3, 2024 · For example, we know that over the past 200 years, the magnetic field has weakened about 9 percent on a global average. However, paleomagnetic studies show the field is actually about the strongest it’s been in the past 100,000 years, and is twice as intense as its million-year average. WebDec 6, 2024 · The field has been weakening for the last 150 years, at a rate of about 5% per century. This weakening could be due to a number of factors, including changes in the planet’s magnetic field, changes in the sun’s activity, or a combination of both. The weakening of the field could have serious consequences for life on Earth.
