Apparently, this file is too large for the board to handle as an image.
The OLD board could take it, this one is a wuss.

Canada is looking pretty good too. Take note they tried to account for mitigation efforts, including GM crops.

The researchers found this by comparing results from almost 100 independent studies—more than double the number used in the IPCC's fourth assessment—that measured the impact of higher temperatures on three of the globe's primary staple crops: maize, wheat, and rice. It's currently the largest dataset we have that demonstrates how crops will respond to changing climates, and it suggests that decreases in yields will grow larger, affect both temperate regions and the tropics, and become increasingly erratic as the weather turns more unpredictable too.
Once mid-century hits, crop losses of up to 25% will become more commonplace, as well—a number that does account for basic mitigation efforts in farming regimes.
