Volcanic eruption energy is partitioned between thermal and mechanical energy. The mechanical energy is distributed between translation (ejecta) and vibrational (tremors). These proportions vary significantly between volcanoes and eruptions. So, perhaps little of the energy is imparted to bring cooling aerosols and particles into the high atmosphere.
A limited nuclear exchange between RF/USA could extend to all large munitions stores, rocket stores, and petrochemical stores. All stores of nuclear launchers, warheads, and supplies intended for strategic war could be targeted.
Imagine all significant above-ground petroleum storage in RF/USA - large petroleum producers - is ignited. All counterforce sorties against targets near wooded areas will result in large forest fires.
