With climate change predicted to alter precipitation and raise temperatures in North American grain-growing regions by 3 to 4 degrees Celsius (about 5 to 7 degrees Fahrenheit) by the end of the century, crops in the future will face dramatically different growing conditions than they do today. But a new study shows that over the last century and a half, North American wheat crops spread into regions with even wider temperature and precipitation differences than will arise over the next century. This analysis suggests it will be possible to adapt to new wheat-growing conditions.
