  Big bang nucleosynthesis (BBN) and the cosmic baryon density from cosmic
microwave background anisotropies together predict a primordial Li7 abundance a
factor of 2--3 higher than that observed in galactic halo dwarf stars. A recent
analysis of Li7 observations in halo stars, using significantly higher surface
temperature for these stars, found a higher Li plateau abundance. These results
go a long way towards resolving the discrepancy with BBN. Here, we examine the
implications of the higher surface temperatures on the abundances of Be and B
which are thought to have been produced in galactic cosmic-ray nucleosynthesis
by spallation of CNO together with Li (produced in alpha + alpha collisions).
While the Be abundance is not overly sensitive to the surface temperature, the
derived B abundances and more importantly the derived oxygen abundances are
very temperature dependent. If the new temperature scale is correct, the
implied increased abundances of these elements poses a serious challenge to
models of galactic cosmic ray nucleosynthesis and galactic chemical evolution.
