Another co-incidence? The Earth's magnetic shield.

"At present, the overall geomagnetic field is becoming weaker; the present
strong deterioration corresponds to a 10-15% decline over the last 150 years
and has accelerated in the past several years; geomagnetic intensity has
declined almost continuously from a maximum 35% above the modern value
achieved approximately 2,000 years ago."

Could there be any connection, as well as correlation, between the reduced
magnetic field and increased co2 or warming? Or could all be caused by some
other factor, perhaps galactic in origin?
