Abstract We examine Hawking radiation from a Schwarzschild black hole in several reference frames using the quasi-classical tunneling picture. It is shown that when one uses, Γ ∝ exp ( Im [ ∮ p d r ] ) , rather than, Γ ∝ exp ( 2 Im [ ∫ p d r ] ) , for the tunneling probability/decay rate one obtains twice the original Hawking temperature. The former expression for Γ is argued to be correct since ∮ p d r is invariant under canonical transformations, while ∫ p d r is not. Thus, either the tunneling methods of calculating Hawking radiation are suspect or the Hawking temperature is twice that originally calculated.
