Lettie Roach (postdoctoral researcher, UW Atmospheric Sciences) recently led a study published in Geophysical Research Letters, evaluating the newest generation Antarctic sea-ice models. This is one of many reports that were produced to inform the Intergovernmental Panel on Climate Change (IPCC). Roach says, “We’ve been looking at all the new models released, and we are seeing improvements overall. The new simulations compare better to observations than we have seen before. There is a tightening up of model projections between this generation and the previous, and that is very good news.’
