from such deadly radiation.
The Earth is sometimes exposed to massive bursts of cosmic
radiation. These plasma clouds have been calculated to have en-
ergy equivalent to 100 billion Hiroshima bombs, but only 0.1%
of it gets past the Earth’s magnetic field and that is absorbed by
the Earth’s atmosphere in any case. The electrical energy needed
to produce this magnetic field is a current of 1 billion amperes,
which is close to the total electrical energy produced by
mankind since history began.
If not for the Earth’s magnetic shield, life on Earth would be
destroyed by deadly radiation or would never have formed in
the first place. However, since the core of the Earth has just the
right properties, as Press and Siever point out, the world we live
in, is protected in this way.

equator

The angle of tilt of the Earth’s axis, 23 degrees and 27 minutes, prevents ex-
treme heat which might afflict between the poles and the equator. Were it
not for that tilt, the temperature differences between the poles and the equa-
tor would rise still further, making impossible a life-supporting atmosphere.
