Which hazard dramatically increases when stratospheric tephra accumulates?

💡 Explanation

Accumulation of tephra aloft increases albedo, causing increased reflection of solar radiation which causes a cooling effect because of reduced solar input; therefore long-term cooling is the answer rather than issues impacting acidity or erosion rates.
