Climate and geophysical accuracy demands fine modeling grids, and very large supercomputers. The best and biggest supercomputers have not been available for climate work, until recently. Watch how results differ if fine meshes and big supercomputers are used.

Why haven’t they been used?

• Computers and the people who know how to program and operate them have been tasked to do “more important things”, like simulate explosions of nuclear weapons
• Congress has not only failed to provide funds to improve the climate models many of them criticize, but have cut funding for U.S. climate research, and related fields

Just remember, when it happens, you will know who to blame. The thing is, what will happen when the rest of the world blames us?

There’s an explanation of this calculation available.

UC Berkeley’s take, and their technical paper.
