In this paper we present the effects produced by temperature in the renormalized vacuum expectation value of the zero–zero component of the energy–momentum tensor associated with a massless left-handed spinor field in the point-like global monopole spacetime. In order to develop this calculation we had to obtain the Euclidean thermal Green function in this background. Because the expression obtained for the thermal energy density cannot be expressed in a closed form, its explicit dependence on temperature is not completely evident. So, in order to obtain concrete information about its thermal behaviour, we develop a numerical analysis of our result in the high-temperature limit for specific values of the parameter α which codify the presence of the monopole.
