He later called this idea the butterfly effect to communicate that small changes in initial conditions, like a butterfly flapping its wings in Nepal, could produce wildly different outcomes, like rain in New York. But better understanding those initial conditions and how the biological world couples with the atmospheric one can provide better predictions about the future of the planet—from where…
