I’ve heard that climate scientists rely on computer models for climate research. How reliable are these models?
Climate models sometimes are derided as little more than guesswork, but such criticisms are off base. Climate models are mathematical representations of climate that are based on the laws of physics. Models are continually subject to vetting and validation. Models have been tested by comparing their simulations of current climate change with actual observations, such as the faster increase in nighttime temperatures compared to daytime temperatures that has taken place.
