The issue focused on several climate models and climate models have been shown to be overly optimistic in their climate projections. Scientists have called for climate models to be subjected to scientific scrutiny to ensure they are realistic.

In this study, researchers looked at climate models at NASA's Goddard Institute for Space Studies and NASA's Jet Propulsion Laboratory to study climate models and climate models in climate models. They found that climate models were less accurate than climate models at NASA's Goddard Institute for Space Studies. The models were also less accurate
