The community of Earth system modelling has a strong interest to reach a horizontal resolution of about 1km for ensemble simulations with global coupled weather and climate models. ...
However, we are still far from being able to run a 1 km coupled ensemble in an operational mode even if some of the fastest supercomputers that are currently available are used. ...
This is a challenge for weather and climate modellers. ...

To further develop the idea of using reversible logic in supercomputing, a design for a 1 Zettaflops supercomputer as required for addressing global climate warming is presented. ...
However, to create such a design requires deviations from the mainstream of both the software for climate simulation and research directions of reversible logic. ...
I conclude a supercomputer based on reversible logic has some chance of addressing the example climate problem, but only if the direction of research into both reversible logic and climate modeling are ...
