Abstract

We model radiative transfer through planetary atmospheres, imposing energy conservation. We solve the heat transfer and the radiative transfer equations in the two stream approximation. As a first order approximation, we use a 2 band model defined by different averages of the optical depth in the UV-visible range τ(vis), and that of the infrared range τ(fir). We show that greenhouse gases that absorb in both ranges, especially where the optical depth is ~1, reduce the greenhouse effect . 

Thus, we search for additional energy sources for global warming and climate change. 

We find a resemblance between the pace of change of the global average temperature anomaly (GATA) and that of the average drift of the north magnetic pole (NMPD), or its separation from the south magnetic pole. We estimate the energy involved in complete pole reversal by assuming a double pole model, and show that it is several orders of magnitude higher than that required for heating of the Earth's system by 1K. We propose that the heating process associated with pole drift, may be connected with friction in the night reconnection zones upon changing of the field geometry, and is evident in the release of non-equilibrium shortwave radiation, and high energy particles which travel towards the Earth and heats it. We find a possible correlation between STEREO data from 2007 (Panchencko et al 2009), and the pace of drift of the NMPD, GATA and auroral intensities and frequency for the same period. 

We also address the question of the average direction of drift of the North magnetic pole. We find that the average drift direction is relatively close to the 1908 Tunguska event coordinates, and ask whether the greatest impact of the 20th century could have initiated the drift process. We calculate the energies brought to the Earth by flying-by asteroids, and show that their energy may suffice to warm the Earth's surface either by direct interaction or by causing pole drift by impact and heating through magnetic energy released in reconnection events.
