Climate change impacts everyone's food supply.

Climate change will have major impacts on the availability of water for growing food and on crop productivity in the decades to come. Increased temperatures will lengthen the growing season in northern temperate zones but will reduce the length almost everywhere else. The livelihoods of rural communities as well as the food security of city populations are at risk.

Abe Lincoln created the National Science Academy, and U.S. Presidents have relied on NSA for advice ever since.
