Planning meetings for the Global Seed Vault in Norway spawned the idea of looking at

As extreme heat spreads across the middle of the country by the end of the century, some states in the Southeast, lower Great Plains, and Midwest risk up to a 50 % to 70 % loss in
average annual crop
yields (corn, soy, cotton, and
wheat), absent agricultural adaptation.
An increase in carbon dioxide and a rise of, for example, one - half degree in the
average temperature, will trigger a significant decline in the rice
yields in Southeast Asia and as much as a 25 percent drop in the
wheat yields in India.
say it has been predicted that «the
average temperature in the semiarid northwest portion of China in 2050 will be 2.2 °C higher than it was in 2002,» and they report that based on the observed results of their study, this increase in temperature «will lead to a significant change in the growth stages and water use of winter
wheat,» such that «crop
yields at both high and low altitudes will likely increase,» by 2.6 % at low altitudes and 6.0 % at high altitudes... Even without the benefits of the aerial fertilization effect and the anti-transpiration effect of the ongoing rise in the air's CO2 content, the increase in temperature that is predicted by climate models for the year 2050, if it ever comes to pass, will likely lead to increases in winter
wheat production in the northwestern part of China, not the decreases that climate alarmists routinely predict.»
India's
wheat crop is already hitting temperature limits, because it's a few hot days or nights — not the
average but the extremes — that cut final crop
yield drastically.
