Magnetic effect on CO 2 solubility in seawater: A possible link between geomagnetic field variations and climate

(August 2008)

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 magneticfield (20 mT) compared to normal field conditions (50 mT). 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 moment may release up to ten times more CO2 from the surface ocean than is emitted by subaerial volcanism.

The fact that the MF effect is similar among the molecular gases suggests that effects seen with air are not due to the paramagnetic susceptibility of O 2, which is too small to explain the observed magnetic-field effects in terms of magnetization effects.

Mysterious link between Earth’s magnetism and oxygen levels baffles scientists

(June 13, 2025)

The strength of Earth’s magnetic field seems to rise and fall in line with the abundance of oxygen in the planet’s atmosphere, a study of geological records spanning the past half a billion years has found.

Strong link between Earth’s oxygen level and geomagnetic dipole revealed since the last 540 million years

(June 13, 2025)

We search for possible observational evidence for such a relationship by examining evolutions of the virtual geomagnetic axial dipole moment and the atmospheric oxygen level over the past 540 million years. We find that both exhibit strong linearly increasing trends, coupled with a large surge in magnitude between 330 and 220 million years ago.

NASA Scientists Find Ties Between Earth’s Oxygen and Magnetic Field

(June 18, 2025)

Data for both Earth’s magnetic field and oxygen extend over comparable ranges in databases that myriad geophysicists and geochemists have compiled. Until now, the authors of the new study say, no scientists had made a detailed comparison of the records.

Wenn ein Treibhausgas baden geht: Wie das Erdmagnetfeld unser Klima beeinflusst

(6. Oktober 2008)

Die Ergebnisse zeigten, dass selbst kleine Veränderungen des Magnetfelds die Löslichkeit von Gasen im Wasser verändern. „Wenn das Magnetfeld schwächer war, löste sich 15 Prozent weniger Luft im Wasser als bei einem stärkeren Magnetfeld“, erläutert Winklhofer. „Für Kohlendioxid war der beobachtete Effekt sogar doppelt so stark.“

Solar Rotation Effects on The Thermospheres of Mars and Earth

(spring 2006)

The first thing that must be understood in this paper is the chain of events that is being tracked. From the Sun‘s rotational quirks, to their effects on CO2 in the respective atmospheres of Mars and Earth. There is also a comparison to older, normalized data from Venus.

(…)

Interestingly, once the data was compiled, there was no correlation found between the levels of CO2 found in the upper atmosphere (~150km on Earth, where this transformation takes place.) Broadening their search, the authors found a strong correlation between the ratio of CO2/O2 and the thermal changes. They feel this suggests that the thermal diffusion effect relies on some form of resonance between the two molecules involved

Pluto Is Emitting X-Rays, and That’s Really Weird

(16.09.2016)

The most likely explanation, according to Wolk, is that high energy particles from the solar wind are colliding with escaped bits of Pluto’s atmosphere—which is mostly nitrogen, carbon, and oxygen—stripping away electrons, and producing an x-ray flare. If true, that’s a very important insight, because it means Pluto’s atmosphere is boiling away into space. Slowly.

The Curiosity rover detects oxygen behaving strangely on Mars

„We‘re struggling to explain this,“ said Melissa Trainer, study author and planetary scientist at NASA‘s Goddard Space Flight Center. „The fact that the oxygen behavior isn‘t perfectly repeatable every season makes us think that it‘s not an issue that has to do with atmospheric dynamics. It has to be some chemical source and sink (of elements into the soil) that we can‘t yet account for.“

It relates back to the methane mystery.
