Short summary
Large volcanic eruptions can eject aerosols into the stratosphere and prevent UV radiation reaching the surface, resulting in surface cooling. A secondary, non-linear effect occurs at high latitudes. While the surface cooling is robust in observations, we show that the non-linear, high-latitude effect is less robust. Climate models have failures at reproducing both aspects, probably because of aliasing with other climate modes and overrepresentation of stratospheric aerosol.
