We report a theoretical analysis of the phonon thermal conductance, 
, for single wall carbon nanotubes (SWCN). In a range of low temperatues
up to 100 K, 
of perfect SWCN is found to increase with
temperature, approximately, in a parabolic fashion. This is qualitatively
consistent with recent experimental measurements where the tube-tube
interactions are negligibly weak. When the carbon-carbon bond length is
slightly varied, is found to be qualitatively unaltered which
implies that the anharmonic effect does not change the qualitative behavior
of .
