What outcome significantly diminishes agricultural yields after a large eruption?

💡 Explanation

Stratospheric aerosol injection leads to decreased solar radiation because the mechanism is global dimming; therefore, crop yields fall over large distances rather than being confined through other local volcanic hazards.

• Which outcome occurs when increased glacial meltwater disrupts North Atlantic gyre circulation salinity gradient?
• Which outcome is caused by gas pressure increase within volcanic domes?
• Which consequence results when a growing lava dome's structural integrity reaches its tensile limit?
• Which outcome primarily occurs via wave refraction around a coastal headland featuring sea stacks?
• Which outcome occurs when vegetation loss weakens levees?
• Which process limits the nutrient supply to surface layers in a stable subtropical gyre's center?
