There are different views regarding the effect of global warming on agriculture
NEGATIVE Effect
1. Effect of this change will vary for C3(i.e. wheat, rice, and beans) and C4(e.g. maize, millets, and sugarcane) plants.
2. As temperature increases with rising CO2 level, some crops may no longer be grown in certain rigions.
POSITIVE Effect
With increased CO2 concentration some plants will show increased photosynthesis,
Greater Root Production
