The impact of climate change on yields will depend on several factors: the type of crop, how much warmer the world gets (which will depend on how quickly we reduce our carbon emissions), where in the world you are, and what we do to adapt.

…

As a general rule, high-latitude or temperate countries will likely see less severe adverse climate impacts — and potentially even increases in yields, despite additional extreme weather events — while farmers in the tropics and subtropics face the largest yield declines, while also having a lower capacity to adapt.

One aspect that could introduce more volatility in production (and food prices) is more extreme changes in water patterns. F]looding or high drought stress can have a large impact on yields.

[A]dopting the best agricultural practices and technologies andstopping climate change would increase yields even more. But it’s still possible for yields to increase over time, even if they rise at a slower rate than they would in a more stable climate. This won’t happen on its own. It will require serious investments to shrink existing yield gaps, and new ones into developing more temperature and drought-resistant crops that are more resilient.
