(CBS/AP) ST. LOUIS - A new report shows the drought in the U.S. heartland is rapidly intensifying and shows no signs of abating.
The U.S. Drought Monitor report released Thursday shows that the amount of land classified in extreme or exceptional drought jumped to more than 20 percent, up 7 percent from last week.
More than 63 percent of the continental U.S. is in some stage of drought, a portion unseen since the Drought Monitor started in 1999.
The drought has sent corn, soybean and other commodity prices soaring in recent weeks.
The Department of Agriculture said Wednesday the drought will help push food prices up by 3 percent to 4 percent next year. Milk, eggs, beef, poultry and pork prices will all be affected by the drought.
Beef prices are expected to see the biggest jump at 4 percent to 5 percent. Dairy product prices are forecast to climb 3.5 percent to 4.5 percent; poultry and egg prices are projected to rise 3 percent to 4 percent; and pork prices are expected to rise 2.5 percent to 3.5 percent in 2013, the agency said.
Besides lower crop yields driving up food prices, the Mississippi River, one of the food-growing heartland's most-vital shipping lanes, is.
"It takes more turns, more shipments to get the same amount of tonnage down to New Orleans," Barge operator Mark Fletcher told CBS News.
Another nasty side-effect of the drought isseeking shelter from the hot and dry conditions in yards and even houses.
Mike O'Toole, of Iowa's AAA Pest Control, told "CBS This Morning": "The insects are being driven inside because they're looking for coolness, dampness -- some place to get out of the sun and out of the heat."
