Confirming the link between a longer ragweed season and climate change:
Studies by an ARS scientist and his cooperators have confirmed what many pollen-sensitive people already suspected: In some parts of North America, ragweed season now lasts longer and ends later. (2/22) http://www.ars.usda.gov/is/pr/2011/110222.htm

Where Old Man River's sedimentation overload really comes from:
Although people tend to blame farm field runoff for the increasing sediment load in the Mississippi River, an ARS hydrologist has shown that stream bank collapse and failure can be chief contributors to high sediment levels in the silty streams and rivers that flow into the Mississippi.

Examining climate change's effects on wheat:
Wheat growers in the Southwest have a better idea about how to adjust to climate change in the decades ahead, thanks to ARS scientists in Arizona who installed infrared heaters in experimental wheat fields to simulate the growing conditions expected by 2050.

More tropical treats for your table:
Hawaiian growers can now export more fruits and vegetables to the U.S. mainland, thanks to ARS researchers who were the first to apply generic irradiation protocols to control a wide variety of quarantine insect pests found on fresh commodities prime for exportation from the Aloha State.
