The way to steer the planet safely away from overwhelming climate crisis may sound familiar, though it’s staggeringly ambitious: just use incredibly powerful and ultra-fast computers. Studies in two separate journals have called for new thinking about global change. One warns that only a genuine accommodation with nature can save humankind from catastrophic change. The other argues that present understanding of the trajectories of global heating is so uncertain that what is needed is a global co-operation to deliver what scientists call exascale supercomputer climate modelling: exascale means calculations at rates of a billion billion operations a second. There’s a snag: nobody has yet built a working exascale computer, though several groups hope to succeed within a few years. But when it’s done it could transform the prospects of life on Earth.
