According to a new paper published by the Journal of Atmospheric and Solar-Terrestial Physics, it appears the cause behind global warming is a lot more complicated than a few molecules of CO2.
The paper titled Geomagnetic South Atlantic Anomaly and global sea level rise: a direct connection? authored by De Santis et al recently has uncovered an “intriguing and to date unreported relationship between the surface area of the South Atlantic Anomaly of the geomagnetic field and the current trend in sea level rise”.
The abstract starts:
These two geophysical variables have been growing coherently during the last three centuries, thus strongly suggesting a causal relationship supported by some statistical tests.”
According to the paper, the first quantitative evidence of a relationship between the geomagnetic field, external field activities and weather or climate change was given by Wollin et al (1971) and by Bucha (1976, 1978).
The abstract states:
The monotonic increase of the SAA surface area since 1600 may have been associated with an increased inflow of radiation energy through the inner Van Allen belt with a consequent warming of the Earth’s atmosphere and finally global sea level rise.”
The good news for the IPCC is that there is little understanding of the connection between the SAA and warming, thus giving them reason enough to just completely ignore it in its next assessment report.
The paper’s abstract:
Although we cannot establish a clear connection between SAA dynamics and global warming, the strong correlation between the former and global sea level supports the idea that global warming may be at least partly controlled by deep Earth processes triggering geomagnetic phenomena, such as the South Atlantic Anomaly, on a century timescale.”
The paper then states that the geomagentic field can modulate charged particles reaching the earth and that the average field strength has decreased substantially over the last 150 years. The paper adds:
This reduction of the field strength may imply an enhanced effect on some climatic parameters, if in fact the energy flux associated with the incoming particles has an effective impact on climate.”
Could this all be just a coincidence? The authors quantified the correlation with two robust tests, and write in their conclusion:
The agreement between global sea level rise and SAA area is spectacular […] a mere coincidence is highly unlikely.”
There you have it. Yet another phenomenon that likely impacts the climate without CO2. Now you understand why in my last post I wrote the IPCC and its 2007 AR4 report are totally obsolete and divergent from reality. The IPCC models are Stone Age. With its focus welded solely on CO2, the IPCC is out to lunch, out of the ballpark – and on a different planet.
