Drought Season's Early Start Presages Another Bleak Year

Conditions in more than half of the United States have slipped into a pattern that climatologists say is uncomfortably similar to the most severe droughts in recent U.S. history, including the 1930s Dust Bowl and the widespread 1950s drought.

The 2013 drought season is already off to a worse start than in 2012 or 2011—a trend that scientists at the National Oceanic and Atmospheric Administration (NOAA) say is a good indicator, based on historical records, that the entire year will be drier than last year, even if spring and summer rainfall and temperatures remain the same. If rainfall decreases and temperatures rise, as climatologists are predicting will happen this year, the drought could be even more severe.

The federal researchers also say there is less than a 20 percent chance the drought will end in the next six months.

"There were certainly pockets of drought as we went into spring last year, but overall, the situation was much better than it is now," said Tom Karl, a climatologist and director of NOAA's National Climatic Data Center. "We are going to have to watch really closely ... Last year was bad enough." Read more >>

Could a solar event spark food riots and meltdowns - one scientist says yes

Read about “The Carrington Event” -- a massive solar flare that hit Earth in 1859. 

If Earth is struck by a large solar flare, some in the scientific community believe:

* The planet will be hit with a widespread loss of power.
* Air travel would be grounded.
* Nuclear plants would be crippled and without sufficient back-up power, dozens could meltdown.
* Satellites would be disabled, causing a serious loss of communication in all areas (military and civilian).
* Food and medicine would be in short supply, setting up the potential for food riots within days of an outage.

The same scientists who believe that a large solar strike could lead to a very rapid societal breakdown say that steps to avoid the problem are available and at a relatively low cost to all of us. What is a “relatively low cost?” They estimate the amount of money needed to insulate the power grid (and ourselves) from trouble to be less than one dollar per American. But Congress said “no” to their proposal.



Is there really cause for concern?

Over the next fourteen months Earth will be on high alert for a huge burst of electromagnetic energy from the sun. This powerful pulse is known as a “Solar Maximum” – an event that could cause catastrophic damage to power grids and communications systems. The peak time for the next big flare is sometime between now and the end of 2013. This possibility has scientists at the National Oceanic and Atmospheric Administration (NOAA) on alert. Tom Bogdan, the director of NOAA’s Space Weather Prediction Center, is monitoring the situation as closely as possible. Read more >>
