  abstract = {{E}xplosive volcanism can alter global climate, and hence trigger economic, political and demographic change(1,2). {T}he climatic impact of the largest volcanic events has been assessed in numerous modelling studies and tree-ring-based hemispheric temperature reconstructions(3-6). {H}owever, volcanic surface cooling derived from climate model simulations is systematically much stronger than the cooling seen in tree-ring-based proxies, suggesting that the proxies underestimate cooling(7,8); and/or the modelled forcing is unrealistically high(9). {H}ere, we present summer temperature reconstructions for the {N}orthern {H}emisphere from tree-ring width and maximum latewood density over the past 1,500 years. {W}e also simulate the climate effects of two large eruptions, in {AD} 1257 and 1815, using a climate model that accounts explicitly for self-limiting aerosol microphysical processes(3,10). {O}ur tree-ring reconstructions show greater cooling than reconstructions with lower spatial coverage and based on tree-ring width alone, whereas our simulations show less cooling than previous simulations relying on poorly constrained eruption seasons and excluding nonlinear aerosol microphysics. {O}ur tree-ring reconstructions and climate simulations are in agreement, with a mean {N}orthern {H}emisphere extra-tropical summer cooling over land of 0.8 to 1.3 degrees {C} for these eruptions. {T}his reconciliation of proxy and model evidence paves the way to improved assessment of the role of both past and future volcanism in climate forcing.},
