Unless we contain carbon, our food supply will be under threat. By 2050, US corn yields could decline by 30%
A multi-decade drought is under way in the Central Plains and the south-west. Wildfires are spreading from Arizona to California, and are burning ridges north of Los Angeles not licked by flames since 1968. Cattle in huge Kansas, Texas and Oklahoma feedlots will drink the Ogallala Aquifer dry in 20 years. This drought, which could rival or exceed the Medieval Drought that occurred about AD1200, could last 30 to 50 years, according to research from the Goddard Space Institute. It will become difficult to grow corn in southern Iowa, and impossible in western Kansas. By mid-century, corn yields could decline by 30%, according to the Iowa State University climatologist Dr Gene Takle.
