Rising CO2 levels could boost wheat yield but slightly reduce nutritional quality

Levels of atmospheric carbon dioxide (CO2) are rising, which experts predict could produce more droughts and hotter temperatures. Although these weather changes would negatively impact many plants' growth, the increased CO2 availability might actually be advantageous because plants use the greenhouse gas to make food by photosynthesis. Now, researchers say that a much higher CO2 level could increase wheat yield but slightly reduce its nutritional quality.
