The heat is not the problem. It radiates into space quite quickly. The current world energy supply per year is over 160 TWh.[1] By comparison, the erruption of Mount Tambora in 1815 released aprox. 237.5 times more energy in a single incident (~38 PWh).[2] The problem at that time was not an extended (regional) heat wave, but the substances that entered the atmosphere and remained there for several years, causing a global weather change.

[2] Other less spectacular examples: 160 TWh is equivalent of 5 to 6 times the energy released by the Mt. St. Helens erruption of 1980 (~28 TWh) or the 2004 Indian Ocean earthquake (~30.6 TWh), or half of the energy released by the 1883 eruption of Krakatoa (~232 TWh), or 1/4 of all nuclear bomb explosions so far (628 TWh).
