Climate models
4 studies3 discoveries
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.

What we know
- This library holds 4 empirical papers on climate models with measured outcomes rather than reviews.
- A 2.2 km convection-permitting model projects wetter northern winters and drier summers, with summer hourly extremes unlike coarser GCMs.
- 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.
Largest unresolved question
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 the evidence shows
Drawn from 4 studies in this library. Mix labels say which citation roles are present; they are not a strength score. Supports means evidence for a finding; Challenges means evidence against a stated position; Qualifies marks scope.

- CMIP6 runs hotter — but its regional extremes scale like CMIP5's
- Storm surge and heavy rain arrive together far more often than independence assumes
- The same aerosol feedback cuts winter ozone and raises it in summer
