Concept
Climate models
Climate-model papers evaluate CMIP or regional models against observations — rain, monsoon, energy balance — rather than shipping unevaluated code.
Models are how we project the 21st century; students need to see where they match and miss.
Evidence
What the evidence shows
Drawn from 4 studies in this library. Each finding starts with a plain-language takeaway, then the denser detail. Supports means evidence for a finding; Challenges means evidence against a stated position; Qualifies marks scope with a short note on each study’s contribution. Challenged positions are labeled — they are not findings.
This library holds 4 empirical papers on climate models with measured outcomes rather than reviews.
- Europe’s first continent-wide 2.2 km rain projections
- Regional extreme sensitivity similar in CMIP5 and 6
- Finer climate models capture South Asian monsoon rain better

CMIP6 and CMIP5 agree on how hot days, cold nights, and heavy rain scale with global warming, even though global climate sensitivity differs.
High-resolution HighResMIP runs reduce dry bias and better match monsoon timing and intensity in the Ganga–Brahmaputra–Meghna basin.
An Eulerian three-parameter storm metric shows CMIP6 GCMs share cyclone biases versus ERA5, while 12 km CRCM6 is usually closest.
Open questions
Tensions and limits
Some items are genuine disagreements on the same question. Others mark different assays, populations, or outcomes — limits on how far one study travels — not a forced fight between papers.
High-resolution rain over Europe is not global climate sensitivity.

Common misconceptions
A higher-resolution model is always more accurate.
Resolution helps some extremes and can still miss large-scale drivers.

What does climate models mean in this library?
Climate-model papers evaluate CMIP or regional models against observations — rain, monsoon, energy balance — rather than shipping unevaluated code.
Name one empirical finding from the climate models papers.
A 2.2 km convection-permitting model projects wetter northern winters and drier summers, with summer hourly extremes unlike coarser GCMs.
What is a limit of climate models evidence here?
High-resolution rain over Europe is not global climate sensitivity.
