Weather of Arabia - Sinan Khalaf - Climate change and its dire effects cast negative shadows on aspects of life. Dangers are increasing and human anxiety is escalating, and the matter is no longer confined to a specific range, as rising temperatures threaten the most important crop in the world, which is wheat.
A recent study by the American Journal of Climate and Atmospheric Sciences confirmed that extreme heat waves and drought, due to climate and its repercussions, threaten global food supplies, which may raise prices.
In the details of the study, the researchers compared the physiological endurance of winter wheat in different climate models, and concluded that high temperatures can slow down the growth of wheat and cause the breakdown of key enzymes within it.
The study was conducted on winter wheat, which is sown in the fall and harvested in the summer, and the study found that severe weather conditions may be too strong for winter wheat grains in both the US Midwest and northeastern China.
The study said that the American Midwest and northeastern China did not witness unprecedented heat waves in the past, but this became possible with climate change, and this would cause a decrease in wheat supplies.
As a result, the researchers said, their presentation of the climate impact on wheat aims to demonstrate the severity of the climate threat to crops in order to prompt political leaders to act and prepare.
Global agricultural productivity is likely to drop by about 15 percent globally by 2050 as a result of rising temperatures and unstable weather, according to the Food and Agriculture Organization of the United Nations (FAO).
