Abstract Climate science is expected to provide usable information policy‐makers, support the resolution of climate change. The complex, multiply connected nature change as a social problem reviewed and contrasted with current modular discipline‐bounded approaches in science. We argue that retains much its initial “physics‐first” orientation, it adheres problematic notion objectivity freedom from value judgments. Together, these undermine ability information. develop usability using work literature on adaptation, but our argument applies all illustrate tension between objective, physics‐first orientation an example about model development practices For solutions, we draw two frameworks for which responds societal challenges: post‐normal mandated generate five recommendations adapting practice science, produce more thereby respond directly challenge These are: (1) integrated cross‐disciplinarity, (2) wider involvement stakeholders throughout lifecycle study, (3) new framing role values (4) uncertainty management, (5) communication.

Abstract Assessing changes in the distribution of biological communities that share a climate (biomes) is essential for estimating their vulnerability to change. We use CMIP6 models calculate biome as featuring classifications such Holdridge’s Life Zones (climate envelopes). found transitional zones between biomes (known ecotones) are expected decline under all change scenarios, but also model consensus remains low. Accurate assessments diversity loss limited certain areas globe, while still poor half planet. identify where there robust estimates and ecotones, lacking. argue caution should be exercised measuring biodiversity latter, greater confidence can placed former. find shortcomings life zone classification related inter-model variability, which ultimately depends on larger problem, namely accurate estimation precipitation compared CRU. Application methodology other confirms findings.
