Climate change is affecting crop yields and reducing global food supplies

The Conversation had an interesting article this week looking at how yields of different crops are changing as the climate is getting warmer. Over the globe, yields are decreasing under warmer conditions, but it varies from place to place. Regions that are farther north are benefiting from the warmer conditions by increasing the length of the growing season as long as they have enough precipitation to overcome the increased evaporation. Regions that are farther south are seeing drier and hotter conditions, leading to reduced yields.  The changes in yield translate into reductions in the amount of consumable food.
