For another, perhaps working in tandem, that explains the geography of the main areas of global surface warming as per GISS etc., see<BR/><BR/>http://www.freewebs.com/psravenscroft/<BR/><BR/>I think deep geomagnetic flux shifts (of core-mantle boundary origin)may be the driver there, simply on the maps match. <BR/><BR/>Ian Plimer thinks El Nino may be driven by bottom heat. Maybe? Up current in the South Pacific Gyre is the hottest seabed region we have, by seismic velocity data. Get back if so inclined. Anyone else, ditto.<BR/><BR/>Peter Ravenscroft <BR/>Closeburn, Queensland. <BR/>p.s.ravenscroft@gmail.comAnonymousnoreply@blogger.com
