Wheat absolutely dominates the world of food. One out of five calories eaten by people on this planet can be attributed to wheat. To sustain an ever growing population wheat production would need to increase growth every year. A new study shows that a warming climate could have the opposite effect and knock out up to 40% of wheat production.
A warming climate can be good for wheat production because it reduces days of the year when freezing temperatures would threaten the crop. The only problem is that the heat is much more of a problem for wheat than the cold. High temperatures, along with reduces rainfall, could absolutely decimate a crop according to Crystal Hunt.
Research done on wheat fields in Kansas showed that the net effect of rising temperatures would have a negative impact on wheat production. A rise of just four degrees Celsius could wipe out nearly half the crop grown.
Negative impacts can be withheld with increased rainfall and irrigation. Weather patterns will play a huge role in the success of wheat grown in the United States in the coming years.
Of course, the rising temperatures will also create more locations closer to the poles that could possibly sustain wheat crops. Canada and areas of South America could be used in the future to help sustain the population of the Earth with wheat.
