These forecasts are based on comprehensive simulations incorporating the best available representations of basic physical processes. (realclimate.org)
For years, the central objectives of climate change science were to document the phenomenon, understand the basic physical processes involved, and determine the degree to which human activity is at fault. (sciencemag.org)
Many of the basic physical processes involved also seem to be approximated with plausible dynamics, but again, they are only indirectly based on foundational first principles, which everyone agrees on. (realclimate.org)
