US crop yields threatened by climate change

American farmers’ livelihoods are at risk from climate change as Midwestern grain yields are poised to tumble amid increasing temperatures and more extreme flooding and droughts, according to a new report.
Rising heat, drought, wildfires and heavy downpours are expected to increasingly disrupt agricultural productivity in the US, according to a National Climate Assessment report. While some northern regions may be able to expand production of alternative crops amid the changes, yields from major US crops are poised to drop.
“Climate change is also expected to lead to large-scale shifts in the availability and prices of many agricultural products across the world, with corresponding impacts on US agricultural producers and the US economy,” the authors write. “These changes threaten future gains in commodity crop production and put rural livelihoods at risk.”
