These icy conditions (Earth's oceans frozen completely with ice more than two kilometers thick) ended violently under extreme greenhouse conditions and triggered the evolution of multicellular animal life. The Snowball Earth theory was previously assumed rather than tested and challenges long-held assumptions regarding the limits of global change.

Software needs to be simple." But does he offer any solutions?"
