In the field of active climate engineering one can try dispersing aluminum [0] or/and (synthetic) diamond micro-particles [1] in the stratosphere to reflect some of the Sun's light back into space. Especially useful because the effect is temporary and self-healing. An accidental "ice age" will resolve on its own in few months after one stops replenishing the stratosphere with the particles.
