As the temperatures rise, many high-producing agricultural regions will feel a squeeze. That matters an awful lot for the 30 percent of the world's population that works in agriculture.

Though warmer temperatures can help crops grow more quickly, for many crops–like grains–the faster the growth, the less time seeds have to mature, reducing worldwide yields. A 2014 United Nations report suggested that food prices could rise up to 84 percent by 2050 as yields fall.

And while higher prices are often good for producers, under climate change, production in certain areas may be decimated: The Central Valley of California, for instance, already experienced a $1.7 billion loss on this year's drought.
