At least from one report I read sometime ago, scientists in Los Alamos National Lab were looking at alternatives to Fortran for their future generations of climate models. C/C++ is under their radar. One reason for the switch is to better deal with unstructured grids. They are moving away from the traditional rectilinear grids. This is more in line with many FEM applications where C++ dominates.
