Which climatic consequence results when stratovolcano eruptions inject sulphur dioxide into stratosphere?

💡 Explanation

When sulphur dioxide reaches the stratosphere, oxidation produces sulphate aerosols persisting for years because gravitational settling removes them slowly, leading to increased albedo and shortwave reflection causing a global cooling period. Therefore global cooling results, rather than increased El Nino, monsoon changes, or reduced cyclones which are influenced by different atmospheric mechanisms.
