  It is argued that the specific heat of $N$ massless Dirac fermions in 2
spatial dimensions interacting with 1/r Coulomb interactions is suppressed
logarithmically relative to its non-interacting counterpart. The
(dimensionless) coefficient of the logarithm is calculated analytically in the
leading order in large $N$ expansion, but to all orders in $e^2N$, a procedure
which takes into account finite temperature screening. Experimental observation
of this effect is expected to occur in a single layer graphene embedded in a
dielectric medium. Its dependence on the dielectric constant is calculated
analytically.
