"Scientists have discovered that the Earth's magnetic field 3.5 billion

weakness, coupled with a strong wind of energetic particles from the
young Sun, likely stripped water from the early Earth's atmosphere."http://news.oneindia.in/2010/03/05/earthsweak-magnetic-field-helped-s...
Then why are we still in the cycle of losing our protective
geomagnetic force and its magnetosphere at roughly 0.1%/year?
Because that's just something you made up.
