“One of the most interesting things about the MIP ensembles is that the mean of all the models generally has higher skill than any individual model.” We hold these truths to be self-evident, that all models are created equal, that … Continue reading

Sea-level report cards, contingency upon model character, and ensemble methods

Done by the Virginia Institute of Marine Science, new sea-level report cards offer a look at current sea-level rise rates, and projections. What’s interesting to me is making the projections conditional upon the character of the model used to project. … Continue reading
