In this blog we often talk about the impacts of El Nino and La Nina about the local climate. But the combination of the two, called ENSO for El Nino Southern Oscillation, also affects the climate across many other parts of the world, causing floods in some places and droughts in others. This article from AgWeb describes how the current La Nina is expected to affect the corn and soybean crops in Brazil, where La Nina is already affecting the climate there. In La Nina years Brazil tends to have more frequent droughts, resulting in less corn pollination due to the dry conditions, and lower yields on other crops. You can read it here.
