火山爆发对气候的影响已得到越来越多的了解，但气候变化如何影响火山系统和过程这一镜像问题，我们称之为“气候-火山影响”，仍然研究不足。鉴于人类活动造成的气候迅速变化，加速对这一专题的研究至关重要。在过去二十年中，我们加深了对地球表面物质分布，特别是与冰川循环有关的冰和水分布变化如何影响地幔熔化、地壳岩浆作用和喷发率的理解。关于气候变化对火山喷发过程的影响的新假设也已出现，包括火山喷发方式和火山羽流上升如何受到不断变化的地表和大气条件的影响，以及火山硫酸盐气溶胶生命周期、辐射强迫和气候影响如何受到背景气候条件的调节。未来对过去气候重建和当前气候观测、火山喷发记录和火山监测以及数值模型的改进，都将在促进我们对气候-火山影响的理解方面发挥作用。重要的机制仍有待探索，例如大气环流和降水的变化将如何影响火山灰的生命周期。促进对气候-火山影响采取全面和跨学科的方法，对于全面了解持续的气候变化如何影响火山活动的环境和社会影响至关重要。
The impacts of volcanic eruptions on climate are increasingly well understood, but the mirror question of how climate changes affect volcanic systems and processes, which we term "climate-volcano impacts", remains understudied. Accelerating research on this topic is critical in view of rapid climate change driven by anthropogenic activities. Over the last two decades, we have improved our understanding of how mass distribution on the Earth's surface, in particular changes in ice and water distribution linked to glacial cycles, affects mantle melting, crustal magmatic processing and eruption rates. New hypotheses on the impacts of climate change on eruption processes have also emerged, including how eruption style and volcanic plume rise are affected by changing surface and atmospheric conditions, and how volcanic sulfate aerosol lifecycle, radiative forcing and climate impacts are modulated by background climate conditions. Future improvements in past climate reconstructions and current climate observations, volcanic eruption records and volcano monitoring, and numerical models all have a role in advancing our understanding of climate-volcano impacts. Important mechanisms remain to be explored, such as how changes in atmospheric circulation and precipitation will affect the volcanic ash life cycle. Fostering a holistic and interdisciplinary approach to climate-volcano impacts is critical to gain a full picture of how ongoing climate changes may affect the environmental and societal impacts of volcanic activity.
