With that in mind, what are the implications to health or life, with an increase or decrease in the earths magnetic field...
"According to the cosmic ray hypothesis, increased solar radiation leads to a more powerful magnetic field, which blocks cosmic rays from reaching Earth. Because cosmic rays provide particles around which water vapor condenses to form clouds, a decrease in cosmic rays would thus lead to a drop in cloud cover. This means that more solar radiation would strike Earth, leading to warming.
But the current study showed that solar radiation has actually decreased, not increased, in the last 20 years. This same period corresponds to a rate of warming equal to or even greater than that of the rest of the century."
