I think the rest of the planet (now, even China!) is taking climate change more seriously than we (USA) have up to now. I think even this country has awoken to the issue in the last few years, except for some vocal science deniers who value this quarter's profits over the next generations' habitability.
It seems to me that being able to continue growing familiar crops would be in the interest of anyone who eats food. And that declining crop yields would worry anyone who is "against" mass famine.
