The year 2012 has been hailed as one that is going to offer diverse extremes, both on the weather and natural events and on the 'man'made' front - e.g. escalation of conflicts and possible 'one minute to midnight' scenarios.
One particular natural occurence that will increase significantly is that of the activity of the sun - solar activity is expected to arrive in major doses, with extreme Coronal mass ejections bringing Geo active storms earthbound - one of the resulting issues of this activity will be the increase in Electro magnetic storms affecting our earth.
Our outer planetary Electromagnetic protective sphere has been rapidly eroding for some time, thus it will not take much for a severe EM storm to make its effect on our planet.
It has happened before in recent history, and will occur again - and soon.
The effects will cause major power outages, satellite communications disruptions and break down in regional power plants - Just be aware that this type of event is a certainty, knowing when is another question, just be prepared!
