Which risk increases when volcanic tephra accumulates on glaciers?

💡 Explanation

Glacial melting increases from tephra deposits due to albedo reduction; darkening the ice causes sunlight absorption, increasing surface temperature via radiative forcing. Therefore, enhanced ablation occurs, because warming far exceeds the effect caused by surface insulation, rather than suppressed drainage.
