The climate in North Asia has been generally cool in recent years  But during periods of slightly higher-than-normal average temperature and humidity in north Asia, crop yields increased significantly  In the next century, the increase in average daily temperature and humidity during that period is expected to be normal for the next century
However, scientists predict that the annual output of crops in most regions will decline in the next century
Crop yields in South Asia are expected to remain unchanged even as average daily temperatures and humidity in the region rise.
