Over multiple generations of CMIP models Arctic sea ice trend predictions have gone from much too stable to about right. Why? The diagnostics highlighted in our model-observations comparison page are currently all temperature based, and show overall that climate models have being doing well on these trends for decades. But there has been increasing attention to trends in non-temperature variables, and there, model performance is more mixed (Simpson et al., 2025).
