Climate change contribute most to corn prices

Research journal Nature Climate Change says the climate change effects the volatility on corn prices, more than the market policies and oil price fluctuation.

Corn is the main feedstock used to make ethanol in America, which has dropped over 6 % this year, after corn output increased by over 4 %. “The likelihood of increasing occurrence of severe hot events in response to increasing global greenhouse-gas concentrations poses a particular risk for field crops,” said researchers N. Diffenbaugh, T. Hertel, M Scherer and M Verma.
