Q: Does a volcanic eruption have an effect on climate change?

Flexi Says:

Plate motions trigger volcanic eruptions, which release dust and CO₂ into the atmosphere. Ordinary eruptions, even large ones, have only a short-term effect on weather (Figure here). Massive eruptions of the fluid lavas that create lava plateaus release much more gas and dust, and can change climate for many years. This type of eruption is exceedingly rare; none has occurred since humans have lived on Earth.
