Magnetic effect on CO2 solubility in seawater: a possible link between geomagnetic field variations and climate

Pazur, Alexander, and Michael Winklhofer (2008), Magnetic effect on CO2 solubility in seawater: a possible link between geomagnetic field variations and climate, Geophys. Res. Lett., 35, L16710, doi:10.1029/2008GL034288.

Abstract
Correlations between geomagnetic-field and climate parameters have been
suggested repeatedly, but possible links are controversially discussed. Here
we test if weak (Earth-strength) magnetic fields can affect climatically relevant
properties of seawater. We found the solubility of air in seawater to
be by 15% lower under reduced magnetic-field (20 microT) compared to normal
field conditions (50 microT). The magnetic-field effect on CO2 solubility is twice
as large, from which we surmise that geomagnetic field variations modulate
the carbon exchange between atmosphere and ocean. A 1% reduction in magnetic
dipole strength may release up to ten times more CO2 from the surface ocean
than is emitted by subaerial volcanism. This figure is dwarfed in front of
anthropogenic CO2 emissions.
