   How long does it take a supercomputer to simulate climate?

   • An initial condition with minimal “drift” is essential to accurately simulate the effects of human-made factors on the climate. But thanks to the ocean and other sluggish components this can take several months even on large supercomputers. No wonder climate scientists have called this bottleneck one of the “grand challenges” of their field.
