许多主要火山喷发都与在喷发前明显开始的十年或更长时间的冷却趋势相一致。尘埃面纱为短期（不到 10 年）的全球变冷提供了正反馈，但似乎不太可能引发冰川作用，甚至不太可能引发 10 至 100 年范围内的轻微气候波动。相反，气候变化会导致地壳应力发生变化，例如，冰和水团的加载和卸载以及轴向和自转速率的变化可能会增加火山（和地震）潜力。
Many major volcanic eruptions coincide with cooling trends of decadal or longer duration that began significantly before the eruptions. Dust veils provide positive feedback for short-term (less than 10 year) global cooling, but seem unlikely to trigger glaciations or even minor climate fluctuations in the 10-to 100-year range. On the contrary, variations in climate lead to stress changes on the earth's crust—for instance, by loading and unloading of ice and water masses and by axial and spin-rate changes that might augment volcanic (and seismic) potential.
