The latest gossip among the End Time Madness crowd will be Solar Flares which will cause some sort of virus causing famine next month, September 2013.  If you go back in America's History you will discover that this has occurred before during America's Dust Bowl of the 1930s.

America's Dust Bowl of 1935...

The ecosystem disruption unleashed plagues of jackrabbits and grasshoppers.
If the dust storms that turned daylight to darkness weren’t apocalyptic enough, seemingly biblical plagues of jackrabbits and grasshoppers descended on the Plains and destroyed whatever meager crops could grow. To combat the hundreds of thousands of jackrabbits that overran the Dust Bowl states in 1935, some towns staged “rabbit drives” in which townsmen corralled the jackrabbits in pens and smashed them to death with clubs and baseball bats. Thick clouds of grasshoppers—as large as 23,000 insects per acre, according to one estimate—also swept over farms and consumed everything in their wakes. “What the sun left, the grasshoppers took,” President Franklin D. Roosevelt said during a fireside chat. The National Guard was called out to crush grasshoppers with tractors and burn infested fields, while the Civilian Conservation Corps spread an insecticide of arsenic, molasses and bran.

The Dust Bowl got its name after Black Sunday, April 14, 1935. More and more dust storms had been blowing up in the years leading up to that day. In 1932, 14 dust storms were recorded on the Plains. In 1933, there were 38 storms. By 1934, it was estimated that 100 million acres of farmland had lost all or most of the topsoil to the winds. By April 1935, there had been weeks of dust storms, but the cloud that appeared on the horizon that Sunday, the 14th, was the worst. Winds were clocked at 60 mph. Day became night.
