High temperatures are required in thermonuclear fusion so that some nuclei are moving fast enough to overcome the barrier to fusion. This is due to the fact that fusion reactions require a significant amount of energy to occur, and high temperatures result in high kinetic energies of the particles involved, increasing the likelihood that they will overcome their electrostatic repulsion and merge into a single nucleus.
