How does climate change affect crops and food supply?

Higher concentrations of carbon dioxide in the atmosphere — a greenhouse gas put there mainly by the burning of fossil fuels — will also reduce food’s nutritional quality, even as rising temperatures cut crop yields and harm livestock. Those changes threaten to exceed the ability of the agriculture industry to adapt.
