Most predictions of the impacts of climate change on society depend on climate models, but these models are calibrated on the modern climate, and often neglect critical components of the climate system that can greatly exacerbate how climate change will proceed, particularly at a local scale. Four climate scientists - from climate physics, hydrology, ecology and epidemiology - shared where they see gaps in our current understanding, and where they believe we may be underestimating the risk of severe climate shocks. The conversation - while dark - helps to inform how we can protect ourselves against some of these risks in the future.
