Global climate model simulations are typically performed at a coarse resolution (e.g. 100km x 100m grid cells) because: Question 1Select one: a. Supercomputers do not provide enough computational power to run models at higher resolutions b. We only have large scale observations to validate models with c. Our understanding of the physics of the climate system at smaller scales is limited d. They are the only spatial scales at which models are good at reproducing temperature trends of the last century
