Earth’s Magnetic Field Changes Climate

Jan. 13, 2009

The Earth’s climate has been significantly affected by the planet’s magnetic field, according to a Danish study published Monday that is unlikely to challenge the notion that human emissions are largely responsible for global warming.

“Our results show a strong correlation between the strength of the Earth’s magnetic field and the amount of precipitation in the tropics,” one of the two Danish geophysicists behind the study, Mads Faurschou Knudsen of the geology department at Aarhus University in western Denmark, told the Videnskab journal.

He and his colleague Peter Riisager, of the Geological Survey of Denmark and Greenland (GEUS), compared a reconstruction of the prehistoric magnetic field 5,000 years ago based on data drawn from stalagmites and stalactites found in China and Oman.

The results of the study, which has also been published in scientific journal Geology, lend support to a controversial theory published a decade ago by Danish astrophysicist Henrik Svensmark, who claimed the climate was highly influenced by galactic cosmic ray (GCR) particles penetrating the Earth’s atmosphere.

Svensmark’s theory, which pitted him against today’s mainstream theorists who claim carbon dioxide (CO2) is responsible for global warming, involved a link between the earth’s magnetic field and climate, since that field helps regulate the number of GCR particles that reach the earth’s atmosphere.

“The only way we can explain the (geomagnetic-climate) connection is through the exact same physical mechanisms that were present in Henrik Svensmark’s theory,” Knudsen said.

“If changes in the magnetic field, which occur independently of the Earth’s climate, can be linked to changes in precipitation, then it can only be explained through the magnetic field’s blocking of the cosmetic rays,” he said.

The two scientists acknowledged that CO2 plays an important role in the changing climate, “but the climate is an incredibly complex system, and it is unlikely we have a full overview over which factors play a part and how important each is in a given circumstance,” Riisager told Videnskab.

So yes indeed, CO2 is merely one of the pieces of the climate puzzle (wait a minute… ah yes, yes it is…) Next to the magnetic field, the influence of the sun, the number of cows on the planet, the cosmic rays, the amount of women giving birth (woops) and the flapping of a butterfly’s wing somewhere in our biggest rain-forest… or, what’s left of it.

So again, wake up people and start to see the whole picture. We need a global change of how we look at living as we are looking at it today. One might suggest we should start living to the tunes of our environment
again and to the tones of all the things we cannot control (well… at least for now… ). Starting a new sort of economics based on trying to live in balance with our natural resources instead of living it up like there is no tomorrow.
