According to the laws of thermodynamics, cold is defined as the absence of heat. Therefore, Iceman does not actually emanate cold, but rather absorbs and dispels heat. Since heat is a form of energy, Iceman's power can be defined as a psionic ability to manipulate thermal energy.

She hinted that his powers were rooted in the psionic manipulation of energy, and not in manipulation of moisture in the air as previously believed.

The Torch was once limited by the quantity of oxygen in his environment, and has been extinguished by sufficient quantities of water, flame retardant foam, and vacuum environments. He can re-ignite instantly once oxygen is returned, with no ill effects.
