We will concisely summarise the progress that has been made in the last 10 to 20 years in understanding the geomagnetic environment and forecasting those disturbances that represent the greatest threats to technical systems. From an analysis of solar wind drivers of geomagnetic disturbances and a description of past extreme events we will illuminate both what we know and what we have yet to understand to mitigate geomagnetic hazards to technical systems. To this end we will need to specifying auroral precipitation and high latitude electrodynamics that have been achieved with global observations and assimilative models. We will further describe the MHD and other models that have been developed to simulate solar disturbances and their magnetospheric and ionospheric, and discuss We then discuss the geomagnetically induced currents and geoelectric fields that produce the direct impacts on vulnerable technical systems. We will conclude with a summary of remaining gaps in our ability to mitigate hazards from geomagnetic disturbances and recommended actions to address those gaps.
