Drought Prompts Natural Disaster Declaration in 26 States

The most widespread drought in the U.S. since 1988 has prompted the U.S. Department of Agriculture (USDA) to issue a natural disaster declaration for about 1,000 counties in 26 states, making farm operators eligible for low interest emergency loans. As of July 10, about 78 percent of the corn-growing region in the U.S. were experiencing some form of drought, and drought conditions have intensified in many corn-growing regions during the past several weeks. Bloomberg News characterized the natural disaster declaration as the largest such declaration in the  USDA's history.

In a move that reflects the “expected impacts of persistent and extreme June and early-July dryness and heat across the central and eastern Corn Belt,” the USDA’s World Agricultural Outlook Board cut the estimate for the 2012 U.S. corn crop by 1.82 billion bushels on July 11, which is a 12 percent cut. As recently as this spring, farmers were looking forward to one of the largest corn crops in years, thanks to a mild winter and ample precipitation.

The disaster declaration covers counties in states from California to Delaware, although it does not include Iowa, the country's biggest corn-producing state. The drought conditions in the U.S. are unusually widespread, although most areas are not experiencing "extreme" or "exceptional" drought conditions, according to the July 10 U.S. Drought Monitor. There have been many more severe droughts in U.S. history, including in the Dust Bowl era of the 1930s.

A key contributor to the drought has been the recent heat that baked much of the country in June and early July, as well as a highly unusual heat wave in March. This week, the National Oceanic and Atmospheric Administration (NOAA) announced that the U.S. has had its warmest year-to-date and warmest 12-month period on record. More than 170 all-time high temperature records were set or tied across the country during June.

“The recent heat and dryness is catching up with us on a national scale,” said Michael J. Hayes, director of the National Drought Mitigation Center at the University of Nebraska at Lincoln, in a press release. “Now, we have a larger section of the country in these lesser categories of drought than we’ve previously experienced in the history of the Drought Monitor.”

Climate studies have shown that the odds of precipitation extremes, including both heavy precipitation and drought, are increasing worldwide as global warming boosts the amount of moisture in the air. However, attributing droughts at the national or regional level is difficult, since natural climate variability plays a large role in influencing weather patterns at such scales. One study released on Tuesday found that manmade global warming made the 2011 Texas heat and drought 20 times more likely to occur compared to the 1960s.

The warm June followed the warmest spring on record, which was the culmination of the warmest March, third-warmest April, and second-warmest May. This marks the first time that all three months during the spring season ranked among the 10 warmest, since records began in 1895.

Too much water?
Too little water?
Too hot?
Too cold?

We have the one stop shop for explanations! Climate change. Yes, Ladies and Gentlemen, boys and girls, if you have to explain anything at all you can use our all inclusive Climate Change explanation kit. We have reasons for drought, reasons for flood, reasons for heat waves and reasons for cold snaps. All in easy to explain sound bites and headlines and pithy comebacks to skeptics.

And if you order today, we’ll include the fantastic Catastrophe Kit. Scare the bejeebus our of anyone with horror stories fit for a Stephen King novel. Seal levels rising 28 feet!  Glacier National Park with out the Glaciers! Famine, plague and Locusts!

Larry, I agree whole heartedly with your sentiment. What were the great dust bowls in the 20’s and 30’s caused by?  12 - 15K years ago they were growing millet in the middle of the Sahara. Yes, we need to take care of our environment, but some of this is a natural phenomenon. Climate change occurs naturally. Its not all man made.

Whistle past the graveyard if you must. This goes WAY beyond normal variability. For the record the dust bowls of the 30’s were caused by natural variability PLUS widespread use of farming methods that greatly exacerbated the problem. Just like today’s climate change is much more extreme than it would have been under normal variability. This time though, it’s already created a feedback loop that will not turn around on a dime.

Sadly we’ve known about global climate change for quite a while now, but have done almost nothing to prevent it before it got out of control. We still need to make changes, but sadly we’ve waited too long to save millions (if not billions) of people from unnecessary hardship, displacement and even death.

But go ahead. Joke about it. While real people in the real world die.
