Prediction: 2013 will be a year of serious global crisis. That crisis is predictable, and in fact has already begun. It will inescapably confront the next president of the United States. Yet this emerging crisis got not a mention at the Republican National Convention in Tampa. We'll see if the Democrats do better.
The crisis originates in this summer's extreme weather. Almost 80% of the continental United States experienced drought conditions. Russia and Australia experienced drought as well.
The drought has ruined key crops. The corn harvest is expected to drop to the lowest level since 1995. In just July, prices for corn and wheat jumped about 25% each, prices for soybeans about 17%.
After a very wet spring in 2011 that delayed planting, the 2012 crop season looked promising as planting conditions were optimal. The outlook was refreshing as it meant few setbacks on the crop. However, the good conditions during planting quickly turned as our family waited and waited for moisture. Unfortunately, when the rains did arrive, they were few and far between.
This has turned into the worst drought our family has seen in generations. And more importantly, the drought this year is not isolated to my local community - our nation has not faced a drought this severe since the 1930s when the Dust Bowl completely devastated American agriculture. July temperatures reportedly broke records set during the Dust Bowl. During the 2012 crop year, the U.S. Department of Agriculture (USDA) designated roughly half of all U.S. counties - 1,496 in 33 states - as disaster areas because of the drought.
As Hurricane Isaac continues to pound the Gulf Coast with rain and wind, meteorologists say the storm could provide some much-needed hydration in parts of the country hit hard by drought.
Isaac will bring "soaking downpours" to parts of Arkansas, Missouri and other Central states into the weekend, according to AccuWeather.

Thunder clapped and rain fell just before Bionce, Sassy and the rest of Mark Argall's prize-winning dairy herd went up for auction.
Had the storm come a few weeks earlier, and if the drought had eased, it might have saved the cows - some of which were named with a bit of poetic license ("You can spell names however you want," he said) for pop-culture divas and celebrities.
