Agriculture and climate change affect each other powerfully: agriculture's significant emissions exacerbate climate change; climate change brings extreme and unpredictable weather, threatening crops, livelihoods, and food security.  To protect all these, and planetary health, agriculture is already figuring out how to get “climate-smart” and lower its emissions of heat-trapping gases: methane, nitrous oxide and carbon dioxide.   What does this climate-smart farming look like, on farms small and large, across the U.S.?  How do farmers shift to doing this?  How long does the transition take?  Do farmers want to shift?  What support and incentives are there for shifting?  And how does carbon pricing fit in?
